Frequently asked questions
Does Amazon Alexa support a Matter water heater?

Can Amazon Alexa automate a Matter water heater?
No — Amazon Alexa adjusts a Matter water heater but cannot start an automation from it. As an action, Amazon Alexa cannot use a Matter water heater in an automation (Med, checked 2026-10-17).
What do I need to add a Matter water heater to Amazon Alexa?
Amazon Alexa 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 Amazon Alexa does support.
