Product notes
Aqara US shop: Matter-over-Thread integrates with Apple Home, Google, Alexa; Zigbee via Aqara hub for exclusive features. Matter Survey (2026-10-15): Temperature + Humidity endpoints; Thermostat Controller binding client; no pressure/light/AQ. Per-platform automation follows temp_humidity type matrix; thermostat binding is SKU-level delta. v0.92: also listed under buttons. Matter Survey telemetry (49 installs, SW 1.1.0.0) shows EP3-5 Generic Switch (MomentarySwitch + Release + LongPress + MultiPress) for the three front buttons. Matter Alpha hands-on (2025-05-01, Matter over Thread): three buttons with short, long and double press triggers in Apple Home; Alexa routines could use only one button; Home Assistant works with extra setup.
v0.47 High add. CSA page Cloudflare-blocked on curl; cert IDs from WebSearch CSA product synthesis cross-checked with Survey VID/PID 0x115F/0x2004. v0.92: also switch_button (three Generic Switch button endpoints; telemetry + Matter Alpha hands-on). Confidence unchanged. Merged the duplicate CSA import record `aqara-aqara-climate-sensor-w100` (+1 source).
How it differs from the type answer
- LCD on-device display + physical buttons — UX beyond bare type matrix.
- Matter Survey: Thermostat Controller (binding) — can drive Matter thermostats without hub routing for some setups.
- Zigbee hub extras are bridged — not Matter fabric features.
- Its three buttons also show as Matter buttons (single, double, long press); which presses can start automations differs by platform (Matter Alpha 2025-05: Alexa only one button).
