View Humidity specifications →Does Meross Smart Multi-Function Hygrometer & Thermometer MS120H include a screen?
Yes, according to the listed specifications. Check which readings or controls are available on the device without opening an app. A 1.9 inch display shows the current reading and cycles between the five measured parameters.
View Screen specifications →Does Meross Smart Multi-Function Hygrometer & Thermometer MS120H support Matter?
Matter is listed as “Meross Hub required”. The stated condition applies to this feature. Verify the exact device type, firmware and features exposed in your chosen platform. Matter support is not proof of feature parity. Not a Matter device itself: the sensor speaks Bluetooth to the Meross Matter Smart Hub (MSH450P), and the hub is what joins Matter. Meross states shipments of the hub and sensors began 2026-09-28.
View Matter specifications →Does Meross Smart Multi-Function Hygrometer & Thermometer MS120H work with Home Assistant?
Home Assistant is listed as “Meross Hub required”. The stated condition applies to this feature. Check the exact integration and firmware. A catalog integration label does not establish local control, official support or available entities. Home Assistant reaches it over Matter through the Meross Matter Smart Hub, or through the community meross_lan integration once Meross adds support.
