Mains powered temperature sensor

Recommendations for mains powered temperature sensor

I'd like to put a temperature sensor in my well pump house. It is maybe 50-60 feet line of sight from one of my hubs, with not much in between. I don't know if that will work or not, but I'll test it with some other devices I have just to see. I only need temperature, but realize the best solution might be some other sensor that just happens to report temperature also. I'd prefer to plug it in so I don't have to worry about batteries in the middle of winter. Thanks for your suggestions!
