I am suddenly getting some strange behavior with my MQTT setup.
I have 2 Raspberry Pi’s. One is running Hassbian and the other is acting as the Mosquitto MQTT Broker.
I have some Hue Dimmer switches and am running the Hue-MQTT-Bridge as a way of integrating them into Home Assistant and everything has been working fine.
However now I cannot get Home Assistant to respond to the Hue Dimmers. I can subscribe to the MQTT topic on the MQTT Broker and can see the messages being received from the dimmers. I have also enabled Home Assistant MQTT logging but for some reason the messages are not being picked up in the log. I have some other devices using MQTT in a similar manner and these are appearing in the Home Assistant log.
I cannot get my head around what the problem could be. Any ideas please?
