Without registration in the Zigbee network, the thermometer does not work. Registration of the thermometer in the Zigbee network is carried out by closing the “reset” contacts with “gnd” for 3 seconds or when turning on the power after flashing. To save power, the registration time is limited by turning off the thermometer after 45 seconds.

Can't I flash any other firmware anymore?

Use Zigbee OTA.

Zigbee OTA

Where can I find it and how can I do it?

pvvx commented 10 months ago

You have flashed a program for the thermometer to work on the Zigbee network. The ZigBee standard has "ZigBee OTA" in its specification.

Your best bet is using this: https://www.zigbee2mqtt.io/guide/usage/ota_updates.html#local-ota-index-and-firmware-files
