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:


SONOFF Official SONOFF RM433 - RF receiver for Remote Control | SONOFF Official SONOFF RM433 is a 433MHz transmitter. With it, you can remotely control the devices and appliances that can receive 433MHz RF Now if we take a look to the power consumption of this sensor we can see that:
When sending signal 9mA during around 0.5sSleep current less than 1uA continuouslyDuration estimation
See relative comparison into the list of compatible devices
It should last more than 1 year with 20 actions per day.

SONOFF PIR2 PIR sensor

I had the chance to receive a whole set of ITEAD 433mhz stuff from them to test and see if they are compatible with OpenMQTTGateway, let's first begin by a look to the sensors and remote control.
As they are all at least compatible with one OMG module, they are now added into the OpenMQTTGateway compatibility list.

Let's begin by the PIR2 PIR sensor:


PIR2 PIR sensorIt looks more modern compared to the other PIR sensors we have seen before, it has a blue led light in the front and is presented as pet immune.

It sends one signal when triggered, the protocol used is compatible with OMG and in particular the following gateway:

Integration of Mijia clock, temperature and humidity sensor to OpenMQTTGateway

Mi flora and Mijia temperature/humidity sensor are now well integrated with OpenMQTTGateway, you can have a temperature sensor that last months just with an ESP32 and one of these 2 devices.

Just upload OMG to the ESP32 and it will automatically read the sensors values published by the devices around you.

A few weeks ago I have seen on aliexpress website a new BLE device made by Xiaomi with a big clock and also the ability to measure temperature and humidity. This device is called Mijia model LYWSD02 and you can find it currently for around 15$.
It was the chance to test it and see if it can be incorporated to OMG.

After a few weeks of waiting :-) I received the device.






We can see directly that it is an e-ink display (same technology used in ereaders), we should have good results in terms of battery lasting.
The device is powered by 2 classical CR2030 Lithium batteries and comes with some stickers and support for different type of mounts.

Once you remove the little part of platic going out t…
