Tools to create a Domoticz plugin for local-tuya devices.

local-tuya-domoticz-tools

Tools to create a Domoticz plugin for local-tuya devices.

💡 The Domoticz version should be 2022.1 or higher.

Creating the plugin

To create a plugin, you will need to create 2 things.

Plugin metadata

This is the XML header that is used to populate the plugin creation page in Domoticz. You can create it using local_tuya_domoticz_tools.PluginMetadata.

Starting the device.

To start the plugin, you need to create the device and register the units.

Check local_tuya_domoticz_tools.plugin.plugin.OnStart for the function signature.

Units should be created using manager.register(...).

For a switch unit, it would look like:

from typing import Dict

from local_tuya import DeviceConfig, ProtocolConfig
from local_tuya_domoticz_tools import UnitManager, switch_unit

from my_device import SwitchState, SwitchDevice


def on_start(
    protocol_config: ProtocolConfig,
    _: Dict[str, str],
    manager: UnitManager[SwitchState],
) -> SwitchDevice:
    device = SwitchDevice(config=DeviceConfig(protocol=protocol_config))
    manager.register(
        switch_unit(
            id_=1,
            name="power",
            image=9,
            command_func=device.switch,
        ),
        lambda s: s.power,
    )
    return device

Units

Units represent a Domoticz device and is associated to a Domoticz hardware.

Manager

The role of the manager is to

• create/remove units: register method
• dispatch the commands from units: on_command method
• update units state: update method

Unit types

• switch
• selector switch
• temperature (accepts values preprocessor)
• set point

For common units parameters, see the base.

Installing the plugin

You should provide a script that will be used to install the plugin. It would look like:

from local_tuya_domoticz_tools import install_plugin, PluginMetadata

def on_start(...):
    ...


if __name__ == "__main__":
    install_plugin(
        metadata=PluginMetadata(...),
        on_start=on_start,
        import_path="my_device.domoticz",
    )

💡 Domoticz path defaults to ~/domoticz a -p option can be passed to change that.

Filtering units

You can automatically add an option to the plugin to filter created units.

To enable it, you need to implement local_tuya_domoticz_tools.UnitId and add all unit IDs, then simply pass it to the install function. UnitManager.register will handle device deletion.
