Don't understand the procedure?

I'm stupid. In the developer console I can read the battery status in the cluster powerCFG batteryAlarmMask. Now I need an example of how I can evaluate and display this in my own converter.

My search has been unsuccessful so far.

Could you describe what you mean by your own converter?
Do you mean you're trying to add a device to your own Zigbee2MQTT install that isn't currently supported with the existing converter? E.g. adding a new device?

Check out https://www.zigbee2mqtt.io/advanced/support-new-devices/01_support_new_devices.html
If it's specifically a Tuya device (even if it's not branded Tuya it may be Tuya based OEM) then there's a separate section for those devices.

You'll probably need to use an external converter https://www.zigbee2mqtt.io/advanced/more/external_converters.html

batteryAlarmMask will sit under the cluster genPowerCfg

Yes, since the support of Lupus devices is currently limited to 2 or 3 devices, I want to tinker with something myself. I don't want to continue using the LUPUS alarm system for home automation, but I want to continue using its components. The thermostat valve and the scenario switch are currently causing me problems. Both only display "OK" (0) or empty (1) via batteryAlarmMask. The scenario button also has the problem that it only displays "Recall Scene ID 0x01" and I haven't worked with that yet.
