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

Gen2/3 devices information

Pro/Plus devies are supported by Shellies Discovery Gen2 script.

Prerequisites

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.

MQTT integration must be configured in Home Assistant.

Installation

You can download shellies_discovery.py file and save it in <config>/python_scripts folder or install the script via HACS. You won't find Shellies Discovery 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.

After installing the script and adding automations, run Shellies Announce automation or restart Home Assistant twice.

Go to HA community for support and help.

How to debug

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

Troubleshooting checklist

  • correct MQTT configuration in Home Assistant with discovery enabled
  • same discovery_prefix in Home Assistant configuration and in script configuration
  • Shellies firmware updated to current version
  • Home Assistant updated to current version
  • enabled MQTT in Shellies configuration
  • you can't manually run the shellies_discovery.py script ('dict object' has no attribute 'payload_json' error)

Shelly device name

The script supports Shelly devices with non-standard names (Internet & Security -> Advanced - developer settings -> Custom MQTT prefix in the Shelly WWW panel). If you want to change the name of the Shelly device, you must first remove the device from Home Assistant (Configuration -> Integrations -> MQTT -> Device -> Remove). Otherwise, all device entities will be duplicated.

Minimal configuration

# configuration.yaml file
python_script:

# automations.yaml file
- id: shellies_announce
  alias: 'Shellies Announce'
  trigger:
    - platform: homeassistant
      event: start
    - platform: time_pattern
      hours: "/1"  # Modifying this if you are using Shelly Motion can drain your device's battery quickly.
  action:
    service: mqtt.publish
    data:
      topic: shellies/command
      payload: announce

- id: 'shellies_discovery'
  alias: 'Shellies Discovery'
  mode: queued
  max: 999
  trigger:
    platform: mqtt
    topic: shellies/announce
  condition:
    - condition: template
      value_template: "{{ trigger.payload_json.gen is not defined }}"
  action:
    service: python_script.shellies_discovery
    data:
      id: '{{ trigger.payload_json.id }}'
      mac: '{{ trigger.payload_json.mac }}'
      fw_ver: '{{ trigger.payload_json.fw_ver }}'
      model: '{{ trigger.payload_json.model | default }}'
      mode: '{{ trigger.payload_json.mode | default }}'
      host: '{{ trigger.payload_json.ip }}'

Battery powered devices

For battery powered devices, the script requires you to set the value of 12h for sleep_mode.period or to configure expire_after yourself.

Don't send announce topic more than once an hour if you're using Shelly Motion! This can quickly drain your device's battery.
