Smoke & CO Detectors - UK

My 3 Nest Smoke and CO detectors are about to run out of life (10 years). Does anyone have any recommendations for Homey compatible replacements?

  • Ideally mains powered (though not essential)
  • Smoke & CO
  • Zigbee or Matter
  • White

Yes, I have 3x Sensereo smoke and 1x Sensereo Smoke + CO

All have been rock solid, never dropped off the mesh.
Not mains powered, but Matter over Thread.

If you are looking for mains powered units the FireAngel products are a great option

Do they have Matter or Zigbee? I can’t find a model number.

They have a Zigbee module (ZB-module) which works in all models that can fit the connectivity modules.
