Compatibility notes
- Grimsholm (Sweden) markets it as one of the first Matter-over-Thread irrigation valves, integrating with 'Apple Home, Google Home, and other Matter-compatible controllers', with flow measurement, freeze and leak detection and IP65 rating (grimsholm.com, read 2026-10-18).
- The product page carries no price or article number and asks visitors to sign up for launch news, so availability appears limited or upcoming (grimsholm.com, 2026).
- Matter vendor/product ID 4992:17 was supplied by the catalog owner and not independently verified against the CSA database.
- Caveat: an Apple Developer Forums thread from September 2026 reports Apple Home refusing to add accessories declaring the Matter 1.3 Water Valve device type (0x0042), so how this valve presents in the Home app should be confirmed on hardware (developer.apple.com/forums/thread/844622).
- Announced; not yet shipping at the time of research.
