Zigbee Smoke Detector ZSDR-850 detected but no battery level

[jeroenst]

I bought a ZSDR-850 smoke detector which according to https://zigbee.blakadder.com/KlikAanKlikUit_ZSDR-850.html is supported.

The device is paired with tasmota zigbee, but only show signal level, no battery level, while it is supported by https://www.zigbee2mqtt.io/devices/ZSDR-850.html

I also don't know which message is send from tasmota-zigbee upon smoke detection.

How can battery level be shown and what message will I receive upon smoke detection?
