Once you calibrate this to a known thermometer (its easy to do), it will keep temperatures within a half degree. I use it in my 25 gallon reef.
Insignia™ - Dock Kit with HDMI and USB for Nintendo Switch – Black NS-GNSTD19 VG

Excellent replacement for the factory dock
If you have more than one television and like to move the Switch around, this is a great convenience.
Works just as well as the factory docking station.
