Home Assistant MQTT Sensors

[chrifey]

For everyone who is using Home Assistant, I created the configuration for a few sensors within HA [1] based on the MQTT data.

My setup is using a local mosquitto instance on the raspberry pi where bb_mqtt is running, that is configured as bridge to publish the topics to another mosquitto instance running on my Home Assistant machine (the connection to there is via user/password over secure channel).

configuration.yaml
