Product notes
CSA primary device type 0x0043 (Water Leak Detector), End Product, Matter over Wi-Fi. Maker/Amazon: Apple Home, Alexa, Home Assistant, Homey. Kit: controller with alarm + pre-bound sensors (supports up to 10).
Jiangsu Shushi Technology Co., Ltd. on CSA. Consumer retail confirmed (ThirdReality shop + Amazon).
How it differs from the type answer
- Two-part system: Matter controller + wireless drip/leak sensors (not a single battery Thread probe like IKEA KLIPPBOK).
- Local 100–120 dB alarm on controller; mute via hardware switch.
- Platform exposure follows leak type matrix; no SKU-level platform test this pass.
