I do not own one but wondering if anyone have tried testing the Bosch Twinguard Smoke/CO2 detector / multi-sensor with Home Assistant’s ZHA inegration (Home Assistant’s built-in native Zigbee gateway component) using this initial Bosch Twinguard 8750001213 quirk (ZHA device handler) from pull request @sarangnemo submitted?
See related Device Support Request and discussion about using the Bosch Twinguard in ZHA here:
FYI, you can find some more instructions here in this community how to test experimental qurks that have not yet been merged:
PS: Note that with the ZHA integration you need to have a moden Zigbee Coordinator radio adapter based on a newer Silicon Labs or Texas Instruments radio chip and Zigbee stack version, like example the official Home Assistant Connect ZBT-1 / SkyConnect, (so it will not work in you have a ConBee/RaspBee or ZiGate based Zigbee Coordinator dongle/stick).
