HomeAssistant error log - MQTT

I happened to go through my logs today and I saw this error:

> Source: helpers/config_validation.py:761
> Integration: MQTT (documentation, issues)
> First occurred: 1 September 2021, 23:08:14 (5 occurrences)

I have searched all my yaml files and cannot find “value” in any of them. Does anyone know where i should be looking?

Probably an auto-discovered mqtt light

Ah! OK thanks

Hey there gents,

Can you please help me out. I have the same issue and do not understand how the above post resolves the issue. Can you please explain further?

Thanks in advance.

if you don’t have a MQTT light defined in .yaml with a ‘value_template’, then it is probably an auto-discovered mqtt light. Both Tasmota and Zigbee2MQTT can send auto-discovery messages to HA, so you don’t have to configure yourself in .yaml.

Check with mqtt explorer what light it is.

Thank you very much for the pointer. I was able to find the offending devices by using MQTT Explorer and then remediate the issue by updating the Tasmota firmware.

Thanks again. :slight_smile:
