Hardware

Hello,

im currently looking for a CO-Detector and a Smoke Detector, which is working with Zigbee and also has a audio alert in case of detection.

I have a zigbee2mqtt stup running, but cannot find detectors, in germany (amazon), where im 100% sure they have zigbee.

Can anyone tell me some models where you know that zigbee2mqtt is working with.
For example i checked out the HS1SA from Heiman, but i can only find the non zigbee version on amazon.

Also, do you have any recommendations on a zigbee repeater (plug and play if possible)? i have this dongle on my HA: SONOFF Zigbee 3.0 USB Dongle Plus,Zigbee Gateway TI CC2652P + CP2102N Zigbee USB Stick,Zigbee Hub für ZHA in Home Assistant or Zigbee2MQTT,Open HAB etc.: Amazon.de: Computer & Zubehör

Thank you.

Same question here. Looking for a combined Smoke / CO Detector in the EU that integrates with HA without having to physically tinker with it. I would prefer a WiFi version, ideally local integration (without cloud / app).

Anyone any ideas?
