RFM69 or CC1101 are excellent 433MHz transceivers, but none of the existing RF libraries in hassio provide support for these transceiver modules (you can use MySensors component but requires you to have an independent gateway on a separate Arduino, Moteino or Rasp-Pi etc).
Hello I’m interested a lot on this to.
Right know I have one esp8266 to work with the RFM69toMQTT Gateway!
But will be better if the raspberry was the node master!
