Frequently asked questions

Does Google Home support a Matter water heater?

Google Home does not list a Matter water heater as a supported type, so heating schedules stay in the maker app (Med, checked 2026-10-18). Google Home shows a Matter water heater but cannot control it (Med, checked 2026-10-18).

Can Google Home automate a Matter water heater?

No — Google Home adjusts a Matter water heater but cannot start an automation from it. As an action, Google Home cannot use a Matter water heater in an automation (Med, checked 2026-10-18).

What do I need to add a Matter water heater to Google Home?

Google Home does not support a Matter water heater, so adding a Matter controller will not make it pair; a hub only matters for the device types Google Home does support.
