How to run a full Zigbee2MQTT instance with frontend on Tuya T6E Android smart home touch panels.

This guide applies to touch control panels such as:

  • Moes T6E Smart Multi-functional Control Panel (Moes store*, AliExpress*, Banggood*)
  • Zemismart T6E (Zemismart store*, AliExpress*)
  • Avatto T6E Central Control Touch Screen (AliExpress*)
  • HiHome T6E Smart Home Control Panel (HIhome EU store*)
  • Tuya T6E Multi-functional Control Panel (Amazon*, Amazon*, AliExpress*)
  • Smatek T6E 4" Whole Home Control Panel (EU Spec. Android 8.1) (Alibaba)*
  • This probably works on any panel with TYZ13S module but is not yet verified.

    This guide assumes you already have adb shell access to the panel.

    Note that Zigbee2MQTT support for Silabs EFR32 Zigbee chips is still marked as experimental.

    T6E Android panels use the Tuya TYZS13 Zigbee module with old 6.5 firmware version which is not supported. To run Zigbee2MQTT first you have to update the firmware.

    Update Zigbee Firmware

    To update the firmware you will need tools:

    • a soldering iron - a basic one is sufficient for small projects like this such as Mustool MT883 (Banggood*, AliExpress*)
    • good solder and flux - don’t get the super cheap stuff and definitely don’t use unleaded solder. I typically get Mechanic brand from AliExpress* and also their RMA223 flux*.
    • Dupont wires*
    • serial to USB flasher - a CH340G based one has been proven to be most reliable (AliExpress* or Amazon*).

    Wiring

    Disassemble the panel to get access to test pads for the Zigbee module. Solder wires to TX, RX, VCC and GND pads.

    Solder wires

    Connect the Dupont cables to the USB adapter:

    T6E adapter
    TX RX
    RX TX
    VCC 3V3
    GND GND

    Flashing

    Install Elelabs Firmware Update Utility.

    Download firmware in .gbl format for EFR32MG13P from ESZP-Firmware repo, I used efr32mg13p-v8-6910-115200.gbl.

    Connect the serial to USB adapter to the PC and note the COM port number.

    Flash the firmware with (replace COM number with yours)

    Elelabs_EzspFwUtility.py flash -f efr32mg13p-v8-6910-115200.gbl -p COM3
    

    The output should be similar to:

    2022/10/12 19:01:57 Elelabs_EzspFwUtility:   Successfully restarted into X-MODEM mode! Starting upload of the new firmware... DO NOT INTERRUPT(!)

    Prepare T6E Panel

    Open an ADB shell and change to root with su command then allow access to the Zigbee module to other users with:

    chmod a+w /dev/ttyS5
    
    px30_evb:/ # ls -al /dev/ttyS5
    crw-rw-rw- 1 gps gps 4,  69 2022-10-06 19:00 /dev/ttyS5
    

    While still a superuser disable the Tuya panel app

    pm disable com.smartpad.fourinchneeu.smart
    

    The underlying launcher is more persistent and we need to hide the .apk from the system.

    First make system partition writeable:

    mount -o remount,rw /system
    

    Rename the .apk:

    mv /system/app/TuyaLauncherInternational/TuyaLauncherInternational.apk /system/app/TuyaLauncherInternational/TuyaLauncherInternational.apk.original
    

    Reboot the panel.

    Install Termux

    Download Termux and install it using adb install

    Launch Termux on the panel.

    Install Zigbee2MQTT

    Install requirements to run Zigbee2MQTT.

    pkg install git python openssl nodejs
    

    Answer Y when asked.

    Clone Zigbee2MQTT from official GitHub:

    git clone --depth 1 https://github.com/Koenkk/zigbee2mqtt.git zigbee2mqtt
    

    You can make your life easier, instead of typing it all up use this from adb:

    adb shell input keyboard text 'git clone --depth 1 https://github.com/Koenkk/zigbee2mqtt.git zigbee2mqtt' && adb shell input keyevent 66
    

    Keyevent 66 is the ENTER key.

    Go to Zigbee2MQTT directory

    cd zigbee2mqtt
    

    Install nodejs dependencies:

    npm ci
    

    If everything went correctly the output of npm ci is similar to (the number of packages and seconds can differ on your device):

    node-pre-gyp info ok
    added 383 packages in 111.613s
    

    Before we can start Zigbee2MQTT we need to edit the configuration.yaml file. This file contains the configuration which will be used by Zigbee2MQTT.

    Open the configuration file:

    nano ~/zigbee2mqtt/data/configuration.yaml
    

    Set your MQTT broker location and credentials then change serial to the port of TYZS13 module:

    serial:
      port: /dev/ttyS5
      adapter: ezsp
    

    It is recommended to use a custom network key. This can be done by adding the following to your configuration.yaml. With this Zigbee2MQTT will generate a network key on next startup.

    advanced:
      network_key: GENERATE
    

    To enable the frontend add the following (see Zigbee2MQTT Frontend documentation for more settings):

    frontend: true
    

    Exit and save the file with Ctrl + X

    Run Zigbee2MQTT with

    npm start
    

    Check if everything is running well and the frontend is available at http://[ip_address]:8080.

    Start Zigbee2MQTT on boot

    Download Termux:boot and install it with adb install.

    Start the Termux:Boot app once by clicking on its launcher icon. This allows the app to be run at boot.

    Create the ~/.termux/boot/ directory with

    mkdir ~/.termux/boot/
    

    Open a new file in that directory

    nano ~/.termux/boot/zigbee2mqtt
    

    Create the following script:

    #!/data/data/com.termux/files/usr/bin/sh
    termux-wake-lock
    cd ~/zigbee2mqtt
    npm start
    

    Reboot.
