          I was using a different approach for smoke sensor read, if you are interested please take a look here: http://forum.mysensors.org/topic/2747/home-automation-multi-sensor-nodes
          There are examples includes of single sensor node and multi-sensor node that include also MQ2 sensor and example how to read the associated MQTT message into HomeAssistant.
