Shellies Discovery Script

janco245 · September 23, 2023, 12:07pm

Hi, I’m new to HA. can you please advise me why I can’t find the integration Shellies Discovery Script?

Shellies Discovery is not an integration, this is a python script.

I spent hours trying to integrate the Shelly Motion 2 in HA. Nothing worked: connection error. Until I came across your Discovery script. Then the Shelly was integrated in five minutes. You are a life saver

I´m trying to get the script for discovery of all my shelly devices running. Being a total newbie I am not sure even how to understand the information in the github page.

What I have done (in my home assistant running in docker container):

copied the script to /python_scripts (the “hello world” script seems to work)
found it in developers tools / services
added the minimal configuration to my configuration.yaml
rebooted HA several times

I keep on getting the below error in the log file:
Invalid config for [python_script]: expected dict for dictionary value @ data['python_script']. Got [{'id': 'shellies_announce', 'alias': 'Shellies Announce', 'trigger': [{'platform': 'homeassistant', 'event': 'start'}, {'platform': 'time_pattern', 'hours': '/1'}], '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.payloa.... (See /config/configuration.yaml, line 33). Please check the docs at https://www.home-assistant.io/integrations/python_script

I think you added shellies_announce and shellies_dicovery automation to the python_script section. This is wrong! You can add automations in the UI.

Thank you for the clarification @Bieniu. Now I got my shellies gen 1 up and running. Now taking step 2 with gen 2 and then exploring all the wonders of HA.

hi @Bieniu,

maybe you can help with my 2 Shelly EM (fw1.14) & your latest script.
I can see both EM show up in the MQTT integration device list, all good as they are pick up by your script.

but I have 2 problems:
A) I try to select one of them to be used for the energy dashboard, but it is not available in the list.
suggesting an integration issue → Expected data source not listed - Home Assistant
B) the energy value returned by MQTT show anything between 0-0.05kWh (or 0-50Wh when I change the unit, I was expecting more something between 2000-3000Wh of real consumption).

I had those problems long time ago (about a year), I notice it after HA update, but maybe not related, I honestly don’t know. this is why I update everything Shelly to latest with some hope to solve the problem, it doesn’t. As you have a better overview and memory of old version history, you maybe have an idea where I should start to look at, to solve those issues.

Thank for your help.

suggestion (not sure):
entities not defined → see manual integration here Integrating your electricity grid - Home Assistant

‘Make sure you set and provide the device_class , state_class , and unit_of_measurement for those sensors.’ → I have no clue how to modify/complete the right yaml file.

Show me screenshot from MQTT Info section and from Developer Tools → States for this energy sensor.

You didn’t show me the screenshot from MQTT Info.

Bieniu · October 8, 2023, 7:03pm

It seems to me that your configuration comes from the very old version of Shellies Discovery.

Pensee · October 8, 2023, 7:11pm

very old (I am using your script since 05/2020)-> that is more than probable, that’s happen when you try to update manually the yaml, not understanding all of it…

“”“This script adds MQTT discovery support for Shellies devices.”""
VERSION = “4.5.3”

MQTT info , I was thinking it was the 2nd screen shoot, can’t see what else do you mean by MQTT info
