Compatibility notes
- Earlier Bluetooth-only Onvis contact/alarm sensor, succeeded by the Thread CS2. The community HomeKit catalog (homedevices.app) reports Bluetooth with firmware 1.1.2 / 2.0.7 / 2.1.18, undated.
- Not on Onvis's current store (onvishome.com), so there is no manufacturer spec page. Likely discontinued.
