One of the biggest advantages of the MST05 is its flexible installation design. You can mount it directly to the wall using the included backplate, hardwire it for a cleaner setup, or place it on a table or countertop using the included stand. Its DIY-friendly design makes installation quick and simple for homeowners.

Even during internet outages, the thermostat continues functioning locally, allowing you to maintain temperature control directly from the device itself.
