Overview

In a smart home with a Thread hub, the Heiman detector watches for smoke with a dual-beam photoelectric sensor and pushes alerts through Apple Home, Google Home, Alexa, SmartThings or Home Assistant. It mounts with screws and runs on an included battery.

Local Thread automations can switch on lights or cut power the moment smoke is seen, even with the internet down. Without a supported border router it works only as a standalone alarm.

Who it's for

Homes using Apple, Google, Amazon, SmartThings or Home Assistant ecosystems suit it. Anyone without a supported hub should choose a standard or Wi-Fi alarm.

Pros and cons

Pros
  • Photoelectric sensing cuts cooking false alarms
  • Works with major smart platforms
  • No Wi-Fi needed
  • Local automation triggers
Cons
  • Requires a Thread border router
  • Smoke sensing only listed
  • Home Assistant setup needs IPv6

Performance notes

Two light beams detect smoke particles scattering, which catches smoldering fires and ignores steam better than ionization sensors. Thread messages travel locally, so automations fire without the cloud.
