IKEA KLIPPBOK (Thread) vs Shelly Flood Gen4 (Wi-Fi) water leak sensors for Matter: alarm, batteries, sensing cable, network needs and CSA certificates.
A Thread sensor that sounds its own alarm versus a Wi-Fi detector with a sensing cable

Both are Matter water leak sensors with a CSA certificate on file. KLIPPBOK uses Thread, so phone alerts need a Thread border router, and it can sound a local alarm with no smart system. Shelly Flood Gen4 joins Wi-Fi and comes with a 2 m sensing cable. Shelly notes that a leak alert does not shut off water by itself.
