- Does the Mill Smart WiFi Floor Thermostat work with Apple Home or HomeKit?
- Likely. It is Matter certified (certificate CSA255A9MAT46331-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Apple Home on a page we hold. Apple says an iPhone using iOS 18 or later can add Matter accessories to the Home app without a home hub. Apple’s Matter page lists thermostats among the accessory types the Home app supports.
- Does the Mill Smart WiFi Floor Thermostat work with Google Home?
- Likely. It is Matter certified (certificate CSA255A9MAT46331-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Google Home on a page we hold. Google says you need a Matter-enabled hub device set up on your home wireless network before you can add Matter devices to Google Home. Google’s supported-device-types page lists the Thermostat type.
- Does the Mill Smart WiFi Floor Thermostat work with Alexa?
- Likely. It is Matter certified (certificate CSA255A9MAT46331-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Alexa on a page we hold. Alexa needs a Matter-compatible Echo; Amazon says its Echo devices support “a subset of Matter 1.5 and lower device types”, so check that yours does.

- Does the Mill Smart WiFi Floor Thermostat need a hub or a Thread border router?

- When was the Mill Smart WiFi Floor Thermostat Matter certified?
- The CSA certified it on Aug 13, 2025 (certificate CSA255A9MAT46331-24). That is its certification date, not a retail release date, which MatterCatalog does not state.
