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 sensor

It 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:

  • 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 it consumes 6mA during around 2s
  • The sleep current is around 14uA

Duration estimation
See relative comparison into the list of compatible devices
This sensor is very well optimized in term of power consumption, it is among the top of the list of the energy savy devices!
It should last several years.

Here is the back side of the package with the main characteristics:

This sensor is powered by 2 AAA batteries, a good choice as these batteries are easy to find and are cheap.

In conclusion a good PIR sensor with a very good autonomy. 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

Get your BLE sensors data into Home Assistant in 5 minutes

You can now upload your board directly from the web browser!  So let's imagine you want to read data from a sensor like a Mi Flora, an LYWSD03MMC, a weight scale, or any other BLE sensor from this list  Plug an ESP32 dev board to your computer USB port Go to this website: https://docs.openmqttgateway.com/upload/web-install.html Select esp32dev-ble Click the install button Depending on your board you may have to press the BOOT button Choose the port that the ESP is connected to. Wait until the process is complete. Release the BOOT button That's it, OMG is now loaded into your ESP32 board without Arduino IDE, platformIO or a binary flasher. Here are the steps in images: Now comes the Home Assistant part: Add the MQTT integration and activate auto discovery Create a user and a password (Configuration->Users) without administrator right for the gateway Well, this is enough for Home Assistant. So let's now connect both: Check the Wifi Access points available with your smartph

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
