The RFM69GW is a RFM69 to MQTT gateway that uses the ubiquitous ESP8266 chip. There are two or three similar projects that I’m aware of but I’ve put together some hardware and firmware features that make it different. by Xose Pérez:
- I’m using Felix Rusu’s RFM69_ATC library so it supports Monteino nodes with Auto Transmission Control feature enabled for an adaptative transmission power: longer battery life & less radio pollution
- RFM69CW footprint, compatible with RFM12B and hence with old Monteinos or even with JeeNodes (untested)
- Web configurable map between node messages and MQTT topics.
- EEPROM persistent configuration using the awesome Embedis library by PatternAgents
