Making your RF 433mhz sensors and devices communicate with your home automation, gateways comparison

After more than one year of usage of home automation (HA) I have seen that one critical point is the communication between the sensors/devices and the HA system. 

 There is several possibilities for that:
  • Infrared
  • 5,8ghz
  • 2,4ghz
  • 867mhz
  • 433mhz
  • wire
  • ...
And for each of these possibility we can have a huge amount of different protocols. The goal of this article is to draft a list of the 433mhz gateways that can be found. We will focus on 433mhz due to the fact that in european countries 433mhz devices/sensors are quite easy to find and with a correct price.

We will take the following citerias:
  • Price
  • DIY complexity
  • Number of protocols taken into account
  • Complexity of home automation integration
And take a look at RFXCom, RFLink, 433toMQTTto433 ESP8266, 433Utils, Broadlink RM... I will put in green the keypoints of each gateway.

E&R = 433mhz emitter and receiver, can be a FS1000A and a XD-RF-5V or a superheterodyne one (recommended)

    Have a look to Nodo (cheap RFLink) : https://www.nodo-shop.nl/en/21-rflink-gateway

    I have a Broadling RmPro and you miss an important advantage or two. It has built in support for IOS/Android control. It also supports 315MHz which as additional common standard for many shutter/blind/gate controls.

      Thanks added, do you know where a list of supported RF protocols can be found?

    For RFlink: http://www.nemcon.nl/blog2/devlist
    It supports over 100 protocols.
    It supports 315, 433, 868mhz and 2.4 Ghz depending on the modules you add to it..

    Have a look at https://github.com/merbanan/rtl_433/blob/master/README.md.

    It's good for receiving data.

    Thank you for compiling the list.
    Do you know if this USB RF Transceiver can be controlled with OpenHAB?

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

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
