Firmware 0.12.x and 0.13.x don't support consumption type for relays.

This script adds MQTT discovery support for Shelly Gen2 devices in the Home Assistant.

This script needs Home Assistant python_script component so, if you never used it, I strongly suggest you to follow the official instruction and check that python_script is properly configured and it's working.

For the device to work with the script, it must have MQTT configured and options RPC status notifications over MQTT and Generic status update over MQTT enabled.

You can download shellies_discovery_gen2.py file and save it in <config>/python_scripts folder or install the script via HACS. You won't find Shellies Discovery Gen2 in the HACS Integrations section, nor add it as a custom repository. You must have a properly configured python_script component to be able to install the script from the HACS Automations section.

Shellies Discovery Gen2 will automatically install/update the script on your Shelly device. Due to python_scripts integration limitations, updating the device script requires the announce automation to run twice.

• Shelly Plus 1
• Shelly Plus 1PM
• Shelly Plus 2PM
• Shelly Plus Add-on
• Shelly Plus H&T
• Shelly Plus I4
• Shelly Plus Plug IT
• Shelly Plus Plug S
• Shelly Plus Plug UK
• Shelly Plus Plug US
• Shelly Plus Smoke
• Shelly Plus Wall Dimmer
• Shelly Pro 1
• Shelly Pro 1PM
• Shelly Pro 2
• Shelly Pro 2PM
• Shelly Pro 3
• Shelly Pro 3EM
• Shelly Pro 4PM
• Shelly Pro EM
• Shelly Wall Display

Battery powered devices like Plus H&T are put to sleep most of the time. For this reason, adding/updating entities configuration for a device should be done as follows:

• enter the device into setup mode (press the button on the device)
• manually run Shellies Announce Gen2 automation

To debug the script add this to your logger configuration:

# configuration.yaml file
logger:
  default: warning
  logs:
    homeassistant.components.python_script: debug
    homeassistant.components.automation: info

• binary sensor
• button
• fan
• light
• sensor
• switch
• update

• the device name is taken from the device configuration
• the relay name is taken from the device configuration
• the relay consumption type is taken from the device configuration (consumption type must contain light or fan to configure light or fan platform)
• if the input type is set to button, device automation triggers are available
• custom MQTT prefixes are supported
