This script adds MQTT discovery support for Shelly devices in the Home Assistant.
Pro/Plus devies are supported by Shellies Discovery Gen2 script.
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.
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.

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
- 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)
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.

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.
