Hello everybody,
Until this morning, I had a working MySensors integration on Home Assistant using the MQTTGateway. This morning, I upgraded my host-system to Ubuntu 20.04 LTS, and although Home Assistant itself is running perfectly, I can’t seem to get the MySensors integration part working again. I am not completely sure this is related to the upgrade, but it would be a very unlucky coincidence
I am running Home Assistant 0.109.3 using Hass.io, installed with Home Assistant supervised installer, running on an Intel NUC, on a Ubuntu 20.04 LTS server, upgrading from a Ubuntu 18.04 LTS server.
My configuration is still quite simple, with 2 remote sensors, one publishing the temperature based on a Dallas sensor, the other publishing both TEMP/HUM based on a DHT22. The configuration.yaml looks like this:
mysensors:
gateways:
- device: mqtt
persistence_file: '/tmp/mysensors.json'
topic_in_prefix: 'MySensorsOut'
topic_out_prefix: 'MySensorsIn'
Now, the problem is in my opinion easily pinpointed to the MySensors integration, as the MQTTGateway has always continued writing sensor-values to the Queue, but since the update, no entities are created anymore.
In the Gateway logs, it looks ok aswell, I think.

In the logs, I can see that the Home Assistant plugin is loaded correctly, and that a subscription is successfully done.

I also know this subscription works well, because creating a manual topic causes the system to react. Publishing MySensorsOut/3/0/0/0/0 causes the following item in the logs:
2020-05-04 14:16:22 DEBUG (MainThread) [mysensors.gateway_mqtt] Receiving 3;0;0;0;0;20

2020-05-04 14:16:22 ERROR (MainThread) [mysensors.handler] Node 3 is unknown, will not add child 0
Other things I have allready tried, without success:
- Restore of a snapshot from when MQTT was still working. Both with Restore and Restore & Wipe. Strangely enough, this doesn’t change anything.
- Disabling and re-enabling of the Mysensors-integration.
- Disabling the persistance-part in the config.
- Restarting the MQTTGateway.
- Restarting almost everything else including emptying the MQTT-queue.
- Update to 0.109.
I have little knowledge about the exact mechanics of the HA MySensors integration. Can anybody else think of something else that could be causing this?
Many thanks & Stay healthy!
Hans.
