How to erase NVMEM with Zigbee2MQTT

NVMEM (NVRAM) - Non-volatile memory that is used to store the Zigbee Coordinator settings.

Warning

This method only works if you have installed Zigbee2MQTT in Linux (not the HA addon).

  1. Stop Service zigbee2mqtt:

sudo systemctl stop zigbee2mqtt

  1. Go to the directory with Zigbee2MQTT installed:

cd /opt/zigbee2mqtt

  1. Run the command to erase NVMEM:

node scripts/zStackEraseAllNvMem.js <PORT>

where <PORT> is the port of your Zigbee coordinator. This is usually /dev/ttyACM0 for stick or /dev/ttyUSB0 for controllers.

  1. Restart the stick/module.

Warning

This step must be performed necessarily, otherwise the stick/module will not work.
