Product notes
LocalSmartHomeGuide: Apple Home / Google Home / HA for Thread or Zigbee mode. Dual-protocol exclusivity is a major SKU delta. v0.90: re-typed switch_button -> on_off_light. CSA DCL VID 0x115F PIDs 0x1003/0x1004/0x1005 primary 0x0100 On/Off Light (the three US certs above). Aqara US specs: WS-K02E 2 buttons 1 channel, WS-K03E 2 buttons 2 channels, WS-K04E 4 buttons 3 channels; relay max 10 A. Matter Survey telemetry (community, 2026-10-16) for the same PIDs: 1-3 On/Off Light endpoints plus 2-4 Generic Switch endpoints (MomentarySwitch only), Electrical Sensor on the root -> also listed under switch_button, single press only.
v0.90 re-type (High): CSA DCL primary 0x0100 On/Off Light -> on_off_light per the v0.89 rule; also_device_types switch_button for the wireless buttons (Generic Switch endpoints from Matter Survey telemetry + Aqara button/channel counts; single press only). Confidence unchanged.
How it differs from the type answer
- Cannot run Zigbee + Matter Thread simultaneously; type matrix assumes the Matter (Thread, default) route only.
- Load relay channel(s) are On/Off Light; the extra buttons appear as Matter Generic Switch endpoints (community telemetry) that send single press only: no double, long or release over Matter.
- Decoupled mode, relay lock and custom double/long press need Zigbee mode + an Aqara hub (Aqara dual-protocol page; Aqara Forum 2025-08 US user).
- Neutral optional: without neutral, 5 W minimum load and no power monitoring (Electrical Sensor); multi-gang variants are separate models.
