Mosquitto

As part of this weekend’s regular service update, I also came across Mosquitto’s new 2.1.2 release. This is my tale… I’m using Mosquitto as the MQTT broker for my IoT thermostats and smart plugs. If you’re interested, you can find more details on my setup in this and this post.

Said mosquitto instance is scraped by mqtt2prometheus to get the data my smart plugs and thermometers produce into my Prometheus instance. Finally, I also migrated my Zigbee2MQTT instance over to the k8s cluster. It controls my Zigbee transceiver and sends the data from my thermometers on to mosquitto. ...
