SONOFF RM433 remote control with 8 buttons

It’s a nice little remote control with 8 buttons, it is powered with a 12V 27 battery.

You can also buy a base, the remote fits into it by a magnet.




The protocol used is compatible with OpenMQTTGateway modules below:

  • ZgatewayRF (ESP32 or ESP8266 with an RF receiver)
  • ZgatewaySRFB (Sonoff RF Bridge)
Here is the official link:


Now if we take a look to the power consumption of this sensor we can see that:
  • When sending signal 9mA during around 0.5s
  • Sleep current less than 1uA continuously
Duration estimation
See relative comparison into the list of compatible devices
It should last more than 1 year with 20 actions per day.

Some pictures:

We can see that the remote is powered by a 12V 27A battery, 12V 23A will not fit into the remote for info.

This little remote control is interesting, I retain the following advantages:
  • 8 buttons
  • possibility to attach it to a wall thanks to a dedicated base
  • nice quality
  • seems robust
I recommend it.

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

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

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
