Highlights

  • Monitors CO, combustible gas, smoke, temperature and humidity
  • CO sensor with a stated design life of up to 10 years
  • 85dB alarm plus flashing light
  • 1000mAh backup battery
  • Sold as 1 unit or a 2-pack

Best for

Renters or RV owners who want a plug-in unit covering several hazards without wiring or an app.

Things to consider

  • It is non-smart, so there are no phone alerts when you are away.
  • The listing does not mention UL or other safety certification; check local code requirements before relying on it as your primary alarm.
  • Smoke rises, while an outlet sits low on the wall, so placement may limit smoke detection compared with a ceiling unit.

Our take

Plenty of coverage for the money in one plug-in box, best used alongside, not instead of, code-required alarms.

Buying from Moes

MOES is a smart buy for DIY smart-home builders who already use Tuya, Smart Life, Zigbee or Matter and want switches, sensors and blind motors for far less than name-brand equivalents. Skip it if you want hassle-free returns, since change-of-mind returns aren't accepted, or if you need gear fast, since standard orders ship from China. Before ordering, confirm the US or EU version, whether a neutral wire is required, and whether you need a hub.
