MQTT Subscribe Sensor

The mqtt_subscribe sensor platform allows you to get external data into ESPHome. The sensor will subscribe to messages on the given MQTT topic and parse each message into a floating point number.

Please note this component only works with MQTT topics that have numeric data! Each time a message that is not a number is published a warning will be shown. Please use the MQTT subscribe text sensor for importing arbitrary text into the ESPHome ecosystem.
