AVATTO S06 IR gateway compatible with OpenMQTTGateway

For this new post we will make it compatible with OpenMQTTGateway; the BAKEEY IR remote on banggood or AVATTO S06 on Aliexpress (the links are affiliated).

Note that this article apply only to the non tuya compatible S06 models. The newest models, marked as tuya compatible are not based on ESP so not compatible with OMG.


From this discussion on Home Assistant forum, I have deducted that the AVATTO gateways may be uploaded with new firmware, so I bought 2 of them. Thanks to their pinout information I was able to quickly get this device up and running with OMG.

Overview

The S06 is a compact IR bridge with FCC, CE, and RoHS marks,you can find it for less than 15$. Here are some photos:




Disassembly

It is not so easy to open, you will need a thin plate, insert it on the junction between the two box parts and do a lever effect at several locations.



We can see inside that the microcontroller is a TYWE3S, the FCC datasheet gives us plenty of information:
  • ESP8266

  • 1mb flash

  • 50K RAM

So we may be able to flash it with an FTDI and upload OMG.


Here is the LED setup:


It has 7 IR emitters LED, one receiver, and one blue LED.

the IR LED is bigger compared to my other AVATTO round gateway.


Upload OpenMQTTGateway.

Set your FTDI to 3.3V

Connect an FTDI following this wiring to the board:


  • BOARD GND - FTDI GND

  • BOARD RX - FTDI TX

  • BOARD TX - FTDI RX

  • BOARD 3.3V- FTDI VCC

  • BOARD IO0 - BOARD GND

  1. Connect the FTDI to your computer

  2. Open your Arduino IDE or platformio

  3. With platformio  type the following command:  platformio run --target erase

  4. With the arduino IDE :Erase flash "All flash content"  & DOUT mode

  5. And now you can flash it with OpenMQTTGateway, with platformio, type the following command: platformio run --target upload

The board is an ESP8266 1MB, here is the configuration used with PIO in the platformio.ini file:



 

[env:avatto-ir]

platform = ${com.esp8266_platform}

board = esp01_1m

lib_deps =

  ${com-esp.lib_deps}

  ${libraries.irremoteesp}

  ${libraries.esp8266_mdns}

build_flags

  ${com-esp.build_flags}

  '-DZgatewayIR="IR"'

  '-DTRIGGER_GPIO=13'

  '-DLED_SEND=4'

  '-DIR_EMITTER_GPIO=14'

  '-DIR_RECEIVER_GPIO=5'

  '-DGateway_Name="OpenMQTTGateway_AVATTO_IR"'

 


The IR receiver use the GPIO5,

the IR emitters is on GPIO14, 

the blue LED on GPIO4

the reset button on GPIO13.


Once flashed you can set up your credentials with your smartphone, click one save and you should see the gateway coming on your broker.


You can now send and receive IR signals and integrate the board with your favorite automation controller!




And now you should be able to control your IR devices with a powerful board.

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

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 .
