Why adding RFM69 compatibility to OpenMqttGateway

The next release of OpenMQTTGateway will introduce the compatibility with RFM69 transceivers based on the work of lowpowerlab and bbx10.

After some discussions about what will be the new module for OpenMQTTGateway we concluded that the rfm69 from HopeRF would be a good candidate. I did the implementation with the most powerfull variant of RFM69 the RFM69HCW.




It offers in one module :

  • Emission and reception
  • It support multiple frequencies 315, 433, 868 and 915mhz
  • It has a range of several hundred meters
  • It has acknowledgment, you know when the data sent has been received by the recipients
  • It can adapt its power related to the distance between sender and receiver
In some word you can now have mqtt data from far sensors with low power consumption.


This first implementation support the rfm69 library which make it compatible de facto with moteinos low power boards.

A second step could be to integrate the library from jeelabs to be compatible with jeenodes and openenergymonitor.

And we can also explore the replacement of the base RF receiver and emitter of the gateway, maybe a big work to do...

As you see there is a lot of things to build and explore with rfm69 !

433toMQTTto433 - Bidirectional ESP8266 NodeMCU gateway between RF 433Mhz signal and MQTT

The goal  is to act as a gateway between 433Mhz sensors and a MQTT broker or between the MQTT broker and 433Mhz actuators, It enables to: receive MQTT data from a topic and send RF 433Mhz signal corresponding to the received MQTT data  publish MQTT data to a different topic related to received 433Mhz signal  It can be an interesting part in an home automation system so as to interface sensors and actuators (wall sockets) with software like openhab . List of compatible sensors here The interest of putting this gateway to an ESP8266 and not on a raspberry pi is to be able to manage security actions at gateway level (power on a siren, cut power to certain devices) following RF data received by sensors without being dependent to the PI for security related actions. [EDIT] all infos are now centralized into  the github repository  take a look at it you will find up to date info about OpenMQTTGateway You need: Software: Mosquitto Arduino IDE latest version (tested ok with 1.6.10

Infrared IR, 433mhz and MQTT on ESP8266 bidirectional gateway OpenMQTTGateway

Following discussions on the home assistant forum people gave me the idea to add Infrared communication to the 433mhz gateway.  The goal is to act as a gateway between 433Mhz sensors, infrared remote controls and a MQTT broker or between the MQTT broker and 433Mhz actuators, infrared devices, It enables to: receive MQTT data from a topic and send RF 433Mhz signal corresponding to the received MQTT data  publish MQTT data to a different topic related to received 433Mhz signal  receive MQTT data from a topic and send infrared signal corresponding to the received MQTT data  publish MQTT data to a different topic related to received infrared signal  It can be an interesting part in an home automation system so as to interface sensors and actuators (wall sockets), your tv, home cinema, hifi ... with software like  openhab  or home assistant . List of compatible RF sensors here [EDIT] all infos are now centralized into the github repository  take a look at it you will find up to d

SONOFF RF BRIDGE + Pilight or How to extend the supported protocols by our little bridge

With version V0.9 of OpenMQTTGateway  @steadramon  &  @puuu  (the ESP library creator) enabled by their work to integrate Pilight library on OMG. Permiting to increase significantly the list of RF protocols of OMG . But now that we have this interesting possibility and with the goal of OMG of beiing multi boards compatible, why not trying to put Pilight on a Sonoff RF Bridge . So as to do this test I ordered a new one so as to be on the same hardware as most of the users (my other RF Bridge is a demonstration old one) So as to decode RF signals the Sonoff RF Bridge has a special dedicated chip (EFM8BB1)  that communicate with the esp8285 with a serial connection. If we want to increase the number of RF protocols compatibles on the device without modifying the hardware, the only software based solution is to hack the  EFM8BB1. This hack is available and made by @ Portisch . The list of protocol is interesting but at the moment not as big as Pilight one. Maybe I will t
