Frost-resistant smart plugs
prices on 5 models— smart sockets and extension cords that allow operation at temperatures below zero. The specific minimum temperature may be different, it's ok to clarify it separately; however, if the device is planned to be used in an unheated room or other similar conditions, it is definitely worth choosing an option from this category.
A typical example of the use of such devices is a garage or workshop in a private house. During a long absence, when the room is not in use, it can not be heated; and some time before arrival, you can remotely turn on a smart socket with a heater connected to it and arrive in an already heated room with comfortable conditions.
