Zigbee2mqtt or WIFI smoke/gas sensor needed

Hi everybody,

can you suggest me any reliable smoke/gas sensor to be integrated into Home Assitant via zigbee2mqtt or via wifi, please?

Thank you!

Not a full smoke and gas in one with Home Assistant solution, but I have been using the Shelly Gas device in stove hood, at water heater and HVAC and pleased with it. Fortunately only tested it, no real use! It is a solid unit, I use with MQTT to HA. For smoke I have the Google Nest devices, but no integration with HA.

Using the Xiaomi gasdetector here

Hi!
Is it reliable (no false alarms)? How long does the battery last?
Thank you.

It works with an external powersupply and no false alarms rhe last 3 years.
It is a Honeywell device.

Shelly gas device is mains powered and has not had any false alarms. It does not detect smoke, which is something I wanted in the stove (poor cooks here :wink: ) As I said, I use the Google Nest devices for smoke and CO.
