Freeing the Silvercrest (Lidl/Tuya) Smart Home Gateway from the cloud

A collection of scripts/programs for freeing your Silvercrest Gateway from the cloud.

More information available here:

Upgrade firmware of the Zigbee module

By default, the Lidl gateway ships with EmberZNet version 6.5.0.0 which is quite old. It is possible to upgrade this to a newer version using a script provided in this repository.

WARNING: For now, it's not guaranteed that you can revert to the stock firmware after flashing the updated one. Please use with caution!

The latest firmware, 6.7.8.0, is available here: https://github.com/grobasoz/zigbee-firmware/raw/master/EFR32%20Series%201/EFR32MG1B-256k/NCP/NCP_UHW_MG1B232_678_PA0-PA1-PB11_PA5-PA4.gbl

The procedure is as follows:

  1. Make sure you have followed the initial setup to gain root SSH access on the device.
  2. Download the latest firmware and place it somewhere convenient.
  3. Execute the firmware_upgrade.sh script from within the scripts folder. Use the IP address of the gateway, the SSH port, the EZSP version, and the filename of the firmware file as parameters, like this: ./firmware_upgrade.sh 192.168.1.4 2222 V7 ncp_firmware.gbl. You should not need to change the EZSP version, V7 is the default shipped with the gateway.
  4. When prompted, enter the SSH password for the gateway. This occurs three times.
  5. The new firmware should now be flashed, and the device will reboot. You can check the version with bellows: bellows -d socket://GATEWAY_IP:8888 info.
