Since a couple of weeks DSMR Reader stops reading the data from my mosquitto server (apart from HA). I can see messages like this in my log which might suggest that something is wrong with my mqtt instance:
“/usr/src/homeassistant/homeassistant/components/dsmr_reader/sensor.py”, line 55, in async_added_to_hass
homeassistant.exceptions.HomeAssistantError: Cannot subscribe to topic ‘dsmr/reading/electricity_delivered_1’, make sure MQTT is set up correctly
However, with MQTT explorer I see the data updated every 10 seconds my the device, and other services like zigbee2mqtt, zwave and espresence keep working as expected.
The only thing that changed is my recorder settings from MySQL to PostgreSQL, but I cannot imagine that this would influence the reading from mqtt.
Reloading the DSMR Reader integration solves the problem (challenge?) for a couple of days.
Anyone has any clues on where to find what’s wrong?
