Fixed

  • Passing a configuration set value parameter that is bigger than the supplied size parameter. (@jfcloutier)

v5.0.1 - 2022-06-27

Fixed

  • Virtual thermostat reporting fan state command class did not actually support that command class (@jfcloutier)

v5.0.0 - 2022-06-24

Refactored the Grizzly.VirtualDevices.Device behaviour. The behavior no longer has an init/1 callback. Moreover, the handle_command/2 callback still exists but second parameter is not Grizzly.VirtualDevices.Device.device_opts() type. Lastly, a new callback device_spec/1 was added.

The change to handle_command/2 also changes the return value expected by the behaviour. If you have implemented this behaviour see the documentation for Grizzly.VirtualDevices.Device.handle_command/2 for new return values.

The Grizzly.VirtualDevices.Thermostat and Grizzly.VirtualDevices.TemperatureSensor have both been updated to reflect the changes to the virtual device behaviour. In order to use either of these virtual devices you will need to call start_link/1 on them before you're able to send commands to them.

This change requires process based device implementations to be supervised outside of the Grizzly supervision tree. This allows the consuming application the ability to control how the virtual devices are started and when and how they should be shut down.

Changed

Added

  • Grizzly.VirtualDevices.Device.device_opts() type
  • Grizzly.VirtualDevices.Device.device_spec/1 callback
  • Support for empty alarm report event params (@jfcloutier)
  • Support long range node ids in the smart start meta extension field :network_status (@jfcloutier)
  • Grizzly.VirtualDevices.whereis/1

Fixed

  • Grizzly.ZWave.Commands.NodeAddStatus.param() value :node_id type now reflects virtual device ids

v4.0.1 - 2022-06-13

Fixed

  • Fix ClockReport command :name field (@jfcloutier)
  • Fix forcing zipgateway cache update when calling Grizzly.Node.get_info/2

v4.0.0 - 2022-05-19

Breaking change in the Grizzly.VirtualDevices.Device behaviour. If you have not implemented a custom virtual device then you can safely upgrade.

If you have implemented a custom virtual device the init/0 callback is now init/1. To upgrade change your implementation to:

@impl Grizzly.VirtualDevice.Device
def init(_) do
  {:ok, my_state, my_device_class}
end

The change is to add the _ as the argument to your init implementation.

Changed

  • Grizzly.VirtualDevice.Devices behaviour init/0 callback is now init/1

Added

Fixed

  • Ensure Grizzly.VirtualDevices.Thermostat device implementation returns :noreply for unsupported command classes. (@jfcloutier)
  • Fix to calculating RSSI averages (@jfcloutier)
  • Crashing the initialization of a new virtual device caused the virtual device network to get in a bad state

v3.0.0 - 2022-05-12

Breaking change in these modules:

In NetworkManagementInstallationMaintenance command class the :speed type is now a list of speed() rather than a single speed. This effects the command PriorityRouteReport parameter :speed. This parameter is now a list of speed() rather than a single value.

If you do not use this command you can safely upgrade with no changes.

If you do use this command you will need to update code that assumes the :speed parameter is single value.

This change was made to better aline with the Z-Wave specification.

Changed

  • Grizzly.ZWave.CommandClasses.NetworkManagementInstallationMaintenance.neighbor_param() type's :speed param returns a list of type speed(). (@jfcloutier)
  • Grizzly.ZWave.Commands.PriorityRouteReport.params()'s :speed param is now a list of speed() than than a single speed(). (@jfcloutier)

Added

Fixed

  • Error when the primary route report would try to be handled (@jfcloutier)

v2.1.0 - 2022-04-27

Added

Fixed

  • When a lock does not encode an UserCodeReport as an event parameter (@jfcloutier)
  • When an unknown user code is encoded as a empty string (@jfcloutier)

v2.0.0 - 2022-03-21

Breaking change

For this release we removed the on_ready option for Grizzly and added the Grizzly.StatusReporter behaviour. This is a module that the consuming application can implement to get a more specific type of ready status. There are a handful of moving parts to getting Z-Wave and Grizzly up, so this behaviour can be extended over time to handle more ready cases.

To use the status reporter:

defmodule MyApp.StatusReporter do
  @behaviour Grizzly.StatusReporter

  @impl Grizzly.StatusReporter
  def read() do
    # Grizzly and Z-Wave are set up!
    :ok
  end

  @impl Grizzly.StatusReporter
  def zwave_firmware_update_status(status) do
    # Grizzly is trying informing you if it tried to update teh Z-Wave firmware
    # and what the status of that attempt is
    :ok
  end
end

New feature

The newest feature is automatic Z-Wave firmware update. This feature is opt-in and will only try to run if configured. This is useful if you need to update the Z-Wave firmware when Grizzly starts. Here's the configuration:

grizzly_opts = [
  # enables the updating the Z-Wave chip
  update_zwave_firmware: true,
  # configure which firmwares you might want to flash to the Z-Wave chip.
  zwave_firmware: [%{chip_type: 7, path: "/path/to/firmware_file", version: "7.16.03"}],
  # path the Z-Wave programmer program provided by Silicon Labs
  zw_programmer_path: "/usr/sbin/zw_programmer",
  # ..other options
]

{Grizzly, grizzly_opts}

Changed

  • removed :on_ready Grizzly option

Added

  • Z-Wave firmware updates on Grizzly start (@jfcloutier)
  • Ability to get the Z-Wave chip version information (@jfcloutier)
  • Add Grizzly.StatusReporter behaviour

v1.0.1 - 2022-02-28

Fixed

  • Ignore extra bytes reported in association group list by some devices (@jfcloutier)
  • Decode 0x00..0x063 as :on in Basic command class to align with Z-Wave specification (@jfcloutier)

v1.0.0 - 2021-12-20

This release bumps Grizzly to v1.0.0. Grizzly has been used for many years now and has helped a product pass Z-Wave certification. Most the work that gone into Grizzly for the last little while has been minor changes and bug fixes, but core API has remained stable.

Thank you to everyone who has contributed over the years!

  • Jean-Francois Cloutier

v0.18.0 - 2021-2-10

This release breaks the DSK API and other supporting APIs. If you have not supported S2 inclusions, smart start, or use the DSK API for any reason then it should be safe to upgrade.

The break to DSKs is the new Grizzly.ZWave.DSK.t() struct. All inclusion and node provisioning commands now expect a Grizzly.ZWave.DSK.t(). There are two times you will need to get a DSK.t():

  1. User input of a DSK pin (the nicely formatted representation)
  2. The binary (<<>>) representation.

For the first case you can use Grizzly.ZWave.DSK.parse/1 and for the second case you can use Grizzly.ZWave.DSK.new/1.

A common use case for DSKs is using the DSK pin (the first 5 digits in the DSK) to do S2 inclusion. This was done by calling Grizzly.Inclusions.set_input_dsk/1. Where the input DSK was an non_neg_integer(). This API has been changed to take a DSK.t().

Example 

dsk_pin = "12345"
{:ok, dsk} = Grizzly.ZWave.DSK.parse(dsk_pin)

Grizzly.Inclusions.set_input_dsk(dsk)

This API is more useful for taking user input (which the DSK pin is), parsing it, and passing the DSK to the inclusion process. Also this pushes validation of DSK to the Grizzly.ZWave.DSK.parse/1 function.

dsk_pin = "123456"
{:error, :invalid_dsk} = Grizzly.ZWave.DSK.parse(dsk_pin)

The DSK.t() has the String.Chars protocol implemented so if you want to a pretty representation of the DSK, say for logging or displaying the DSK to the user, you call the to_string/1 function on the DSK.t(). Also, see Grizzly.ZWave.DSK.to_string/2 for more details.

If you need to access the raw binary form of the DSK you the DSK.t() exposes the :raw field, so you can access that via dsk.raw.

This release also added support S2/SmartStart QR code generation. See the Grizzly.ZWave.QRCode module for more details.

Changed

Added

Thank you to those who contributed to this release:

  • Jean-Francois Cloutier

v0.17.1 - 2021-1-12

Added supported for using zipgateway versions >= 7.14.2.

When upgrading from a zipgateway version less than 7.14.2 you should provide the zgw_eeprom_to_sqlite utility in your system or firmware. The utility should be located in /usr/bin. Grizzly will try to run the utility if we detected it.

You can configure the database file and eeprom file via :database_file and :eeprom_file options for the Grizzly.Supervisor. These are optional and no changes are necessary for how you start Grizzly if you have already been using Grizzly.

Added

  • Support for zipgateway versions >= 7.14.2
  • :eeprom_file to supervisor args (optional)
  • :database_file to supervisor args (optional)

Thank you to those who contributed to this release:

  • Frank Hunleth

v0.17.0 - 2021-1-8

This release does a major overhaul on the Grizzly.Transport behaviour. If you haven't implemented a custom transport this release should not effect you and you should be able to update with out too many issues, see the "Removed" section of this release to note any other breaking changes. If you have created a custom transport please see the documentation for Grizzly.Transport to see how transports are now implemented.

Added

Changed

  • Refactored the Grizzly.Transport behaviour - please see documentation to see how to use the behaviour now.

Added

  • Cookbook documentation for common uses of Grizzly

Changed

  • Reduced the amount of logging

v0.14.5 - 2020-09-02

v0.14.2

Added

Removed

  • crc dependency

v0.14.1

Enhancements

Thank you to those who contributed to this release:

  • Jean-Francois Cloutier

v0.14.0

This breaking change has to do with how Grizzly is started. It is no longer an application. Grizzly exposes the Grizzly.Supervisor module for a consuming application to add to its supervision tree. All other APIs are backwards capable.

See the upgrade guide for more specifics on how to upgrade.

Breaking Changes

  • Grizzly is not an OTP application anymore and will need to be started manually via the new Grizzly.Supervisor module
  • All application config/mix config options are not used
  • Removed the Grizzly.Runtime module

Enhancements

Thank you to those who contributed to this release:

  • Jean-Francois Cloutier

v0.13.0

This update breaks the main Grizzly.send_command/4 API as Grizzly use to respond with different tuples but now it will return with the new Grizzly.Report.t() data structure. A full guide on the breaking changes and what needs to be updated can be found here.

This change allows us to gather more information about a response from Grizzly. For example, with this change you can get transmission stats about network properties when sending a command now:

{:ok, report} = Grizzly.send_command(node_id, command, command_args, transmission_stats: true)

report.transmission_stats

See the Grizzly.Report module for full details.

Enhancements

  • Add Grizzly.Report
  • Add getting transmission stats for sent commands
  • Docs and type spec updates

v0.12.3

Fixes

  • Handle multichannel commands that are not appropriately encapsulated

Thank you to those who contributed to this release:

  • Jean-Francois Cloutier

v0.12.2

Enhancements

v0.12.1

Enhancements

Fixes

  • Some devices send alarm reports that do not match the specification in a minor way. So, we allow for parsing of these reports now.
  • Fixed internal command class name to module implementation mapping issue for :switch_multilevel_set and :switch_multilevel_get commands.

Thank you to those who contributed to this release:

  • Jean-Francois Cloutier

v0.12.0

There is a small breaking change that will only effect you if you hard have :water_leak_detected_known_location and :water_leak_dropped_known_location hard coded into your application for any reason. These are notifications about water leaks, and so if you have not directly tried to match on or handle logic about water leak notifications then this breaking change should not effect you.

From a high level this release provides updates to Z-Wave notifications in terms of command support and package parsing, extra tooling for better introspection, a handful of new commands and command classes, and helpful configuration items.

Enhancements

Fixes

Thank you to those who contributed to this release:

  • Jean-Francois Cloutier

v0.11.0

Grizzly now supports parsing alarm/notification parameters as a keyword list of parameters. This change is breaking because the event parameters use to be the raw binary we received from the Z-Wave network and now it is a keyword list.

We only support lock and keypad event parameters currently, but this puts into place the start of being able to support event parameters.

Enhancements

  • Support parsing event parameters for lock and keypad operations

Thank you to those who contributed to this release:

  • Jean-Francois Cloutier

v0.10.3

Enhancements

Fixes

Thank you to those who contributed to this release:

Enhancements

Fixes

  • Sensor types returned from the support sensors report
  • Broken link in docs

Thank you to those who contributed to this release:

  • Jean-Francois Cloutier

v.0.10.1

Enhancements

Thank you to those who contributed to this release:

  • Jean-Francois Cloutier

v0.10.0

Removed the parameter :secure_command_classes from Grizzly.ZWave.Command.NodeInfoCacheReport. Also updated the param :command_classes to be a keyword list of the various command classes that the node can have.

The fields in the keyword list are:

  • :non_secure_supported
  • :non_secure_controlled
  • :secure_supported
  • :secure_controlled

If you are using :secure_command_classes for checking if the device is securely added you can update like this:


{:ok, node_info} = Grizzly.Node.get_info(10)

Keyword.get(Grizzly.ZWave.Command.param!(node_info, :command_classes), :secure_controlled)

Enhancements

Fixes

  • Internal command class name discrepancies

Thank you to those who contributed to this release:

  • Jean-Francois Cloutier

v0.9.0-rc.4

Enhancements

Fixes

  • When resetting the controller we were not closing the connections to the nodes. This caused some error logging in zipgateway and also left open unused resources. This could cause problems later when reconnecting devices to resources that were already in the system.

Thank you to those who contributed to this release:

  • Jean-Francois Cloutier

v0.9.0-rc.3

Enhancements

  • Some Z-Wave devices report the wrong value for the switch multilevel report so we added support for those values.

Fixes

  • Grizzly.DSK -> Grizzly.ZWave.DSK
  • Grizzly.Node.add_lifeline_group -> Grizzly.Node.set_lifeline_association

We moved all the commands and command classes to be under the the Grizzly.ZWave module namespace and refactored the command behaviour.

Grizzly.send_command Changes

The main API function to Grizzly has changed in that it only takes a node id, command name (atom), command args, and command options.

Also it no longer returns a plain map when there is data to report back from a Z-Wave node but it will return {:ok, %Grizzly.ZWave.Command{}}.

Please see Grizzly and Grizzly.ZWave.Command docs for more information.

Connections

Grizzly uses the zipgateway binary under the hood. The binary has its own networking stack and provides a DTLS server for us to connect to. Prior to Grizzly v0.9.0 we greatly exposed that implementation detail. However, starting in Grizzly v0.9.0 we have hidden that implementation detail away and all connection functionally is handle by Grizzly internally. This leaves the consumer of Grizzly to just work about sending and receiving commands.

If you are using %Grizzly.Conn{} directly this is no longer available and you should upgrade to just using the node id you were sending commands to.

When Grizzly is Ready

We use to send a notification to let the consumer to know when Grizzly is read. Staring in v0.9.0 the consumer needs to configure Grizzly's runtime with the on_ready module, function, arg callback.

config :grizzly,
  runtime: [
    on_ready: {MyApp, :some_function, []}
  ]

See Grizzly.Runtime for more details

Inclusion Handler Behaviour

Adding and removing a Z-Wave node can be a very interactive process that involves users being able to talk to the including controller and device. The way Grizzly < v0.9.0 did it wasn't vary useful or robust. By adding the the inclusion handler behaviour we allow the consumer to have full control over the inclusion process, enabling closer to Z-Wave specification inclusion process.

See Grizzly.InclusionHandler and Grizzly.Inclusions for more information.

Command Handler Behaviour

If you need to handle a Z-Wave command lifecycle differently than the default Grizzly implementation you can make your own handler and pass it into Grizzly.send_command as an option:

Grizzly.send_command(node_id, :switch_binary_set, [value: :on], handler: MyHandler)

See Grizzly.CommandHandler for more information.

Supporting Commands

At the point of the rc.0 release are not fully 100% supporting the same commands as in < v0.8.8, but we are really close. The commands that we haven't pulled over are not critical to average Z-Wave device control. We will work to get all the commands back into place.

Thank you to Jean-Francois Cloutier for contributing so much to this release.

v0.8.0

Adds support for handling SmartStart meta extension fields.

These fields give more information about the current status, inclusion methods, and product information for the SmartStart device.

There are two breaking changes:

  1. All SmartStart meta extensions were moved from Grizzly.CommandClass.NodeProvisioning namespace into the Grizzly.SmartStart.MetaExtension namespace.
  2. Upon finalizing the meta extension behaviour and API we made changes to how previously supported meta extensions worked. Namely, we added a new/1 callback that does parameter validation, and returns {:ok, MetaExtension.t()}. This breaks the pervious behaviour of to_binary/1 functions in perviously implemented meta extensions.
  • Enhancements
    • Full support for SmartStart meta extensions
    • Add meta_extensions field to Grizzly.CommandClass.NodeProvisioning commands that can handle meta extensions
    • Update Grizzly.Conn.Server.Config docs
  • Fixes
    • Invalid keep alive (heart beat) interval
    • Set correct constraints on Time command offset values

Thank you to those who contributed to this release:

  • Jean-Francois Cloutier
  • Ryan Winchester

v0.7.0

Introduces SmartStart support!

SmartStart will allow you to pair a device to a Z-Wave controller with out turning the device on. Devices that support SmartStart will have a device specific key (DSK) that you can provide to the controller prior to turning on the device.

iex> Grizzly.send_command(Grizzly.Controller, Grizzly.CommandClass.NodeProvisioning.Set, dsk: dsk)
:ok

After running the above command you can plug in your SmartStart device and the controller will try to join the Z-Wave network automatically.

As a note, your controller might not have the necessary firmware to have SmartStart.

To verify this you can use RingLogger to read zipgateway logs which at the start will log if the controller supports SmartStart.

Breaking Changes

Breaking change to the return value of sending Grizzly.CommandClass.ZipNd.InvNodeSolicitation.

When using that function send_command would return {:ok, {:node_ip, node_id, ip_address}} but now it returns {:ok, %{ip_address: ip_address, node_id: node_id, home_id: home_id}}.

  • Enhancements
    • SmartStart support through the NodeProvisioning command class
    • Added home_id field to Grizzly.Node.t()
    • Support fetching home_id of the Z-Wave nodes when fetching Z-Wave information about the node

v0.6.6

  • Fixes
    • Application start failure when providing the correct data structure to the zipgateway_cfg configuration field

v0.6.5

  • Enhancements
    • Support GetDSK command
    • Support FailedNodeRemove command
    • Allow zipgateway_path configuration
    • Generate the zipgateway.cfg to allow device specific information to be passed into the zipgateway runtime.

v0.6.4

  • Enhancements
    • Validation of UserCode arguments to help ensure usage of Grizzly follows the Z-Wave specification

v0.6.3

  • Enhancements
    • Supports AssociationGroupInformation Command Class

v0.6.2

  • Enhancements
    • Remove the dependence on pidof allowing grizzly to work on any nerves device without the need of busybox

v0.6.1

  • Enhancements
    • Update commands IntervalGet and ManufacturerSpecificGet to be more consistent
    • Better handling of invalid ManufacturerSpecific info received from devices

v0.6.0

Changed Grizzly.CommandClass.CommandClassVersion to Grizzly.CommandClass.Version and changed Grizzly.ComamndClass.CommandClassVersion.Get to Grizzly.CommandClass.Version.CommandClassGet as these names reflect the Z-Wave specification better.

If you only have used Grizzly.get_command_class_version/2 and the related function in Grizzly.Node module this change should not effect you.

  • Enhancements
    • Add support for:
      • MultiChannelAssociation Command Class
      • WakeUp Command Class NoMoreInformation command
      • Complete Association Command Class
      • ZwaveplusInfo Command Class
      • Version Get Command
    • Clean up docs
    • Renamed Grizzly.CommandClass.CommandClassVersion to Grizzly.CommandClass.Version
    • Renamed Grizzly.CommandClass.CommandClassVersion.Get to Grizzly.CommandClass.Version.CommandClassGet

v0.5.0

Introduces Grizzly.Command.EncodeError exception and updates encoding and decoding functions to return tagged tuples. We now use these things when trying to send a command via Grizzly.send_command/3 so if you have invalid command arguments we can provide useful error handling with {:error, Grizzly.Command.EncodeError.t()}. The EncodeError.t() implements Elixir's exception behaviour so you can leverage the standard library to work with the exception.

Unless you have implemented custom commands or used one of the many command encoders or decodes explicitly this update should not affect you too much. If you have used the encoder/decoders explicitly please see the documentation for the ones you have used to see the updated API. If you have written a command we encourage you to validate the arguments and return the {:error, EncodeError.t()} to improve the usability of and robustness your command. The new Grizzly.Command.Encoding module provides some useful functionality for validating specs for command arguments.

  • Enhancements
    • Provide command argument validation and error handling via Grizzly.Command.EncodeError.()
    • Update all the command arg encoder/decoder to use tagged tuples for better handling of invalid command arguments
    • Introduces new Grizzly.Command.Encoding modules for helping validate command arugment specifications
  • Fixes
    • Crashes when providing invalid command arguments

v0.4.3

v0.4.2

  • Enhancements
    • Support NoOperation command class

v0.4.1

  • Enhancements
    • Add support for Network Management Installation Maintenance
    • Updates to docs and examples

v0.4.0

Changed how configuration works.

Grizzly now requires the serial port to be configured:

config :grizzly,
  serial_port: "/dev/ttyACM0"

Also added the pidof_bin configuration option to allow official Nerves systems to work with some of the Grizzly scripts the call that utility by using the busybox package and pointing to the executable of pidof that is compiled with busybox.

If you are using a custom system you can add that utility to the busybox config, and not need to use this configuration option.

config :grizzly,
  pidof_bin: "/srv/erlang/lib/busybox-0.1.2/priv/bin/pidof"

Double check the version of busybox you are using and make sure that version matches the version in the pidof_bin path.

Changed run_grizzly_bin to run_zipgateway_bin.

v0.3.1

  • Enhancements
    • Implement multilevel sensor command to get supported sensor types

v0.3.0

The big change here is removing the in memory cache for devices on the network. Most common use cases will be for a consuming application to hold on to the network device information and apply some costume logic to now that is managed.

Also, we would have to keep both the external and internal cache in sync, which is really hard and was creating an odd event based system, which also lends itself to complexity.

Breaking Changes

Grizzly.list_nodes() -> Grizzly.get_nodes()

This is mostly because before we were listing nodes from a cache, and now we are getting nodes from the Z-Wave network.

Also with get_nodes we don't automatically connect to the nodes. So getting and connecting to all nodes on the Z-Wave network might look something like this:

def get_and_connect() do
  case Grizzly.get_nodes() do
    {:ok, nodes} -> Enum.map(nodes, &Grizzly.Node.connect/1)
    error -> error
  end
end

Grizzly.update_command_class_versions/2 -> Grizzly.update_command_class_versions/1

Before we would pass if the update would be async or not after reviewing how this gets used it made sense to always do it sync. Also it returns a Node.t() now with the command classes updated with the version.

This is the same change found in Grizzly.Node.update_command_class_versions

Grizzly.command_class_version/3 -> Grizzly.get_command_class_version/2

Removed the use_cache param as there is no longer a cache.

Same change found in Grizzly.Node.get_command_class_version
