Compatibility notes
- Zigbee contact sensor (US$14.99-19.99, two AAA batteries); the product page says Apple HomeKit, Google Home, Alexa and SmartThings support is 'enabled by Smart Bridge MZ1 (sold separately)' (thirdreality.com, read 2026-10-18).
- The MZ1 bridge generates a Matter setup code so it can be added to Apple Home via multi-admin, and Third Reality support says the sensor then appears as a contact sensor (3reality.com guides, read 2026-10-18).
- Indoor use only; not for mounting on metal doors or windows (thirdreality.com, read 2026-10-18).
