Review on 🌡️ Enhanced Blue LED Temperature Display with External Sensor by Sure Electronics by Eduardo Reyes

Works great! I powered it with a cheap 12V power supply (Etekcity GD-001). The connecting wires were correctly aligned (red + and black -) so they seem to have solved this problem. If you carefully open the back, you will see 4 DIP switches that you can use to customize the display. You must be online to view installation information. It was set up the way I wanted it when I got it. #1 on, #2 off to display in F, #3 on, #4 off. to display the temperature readings from channel 1. The blue display is not too bright, but is easy to read at night. I have a couple of digital clocks in my bedroom, I don't need the others. I just wanted a digital temperature gauge. I assembled my usual thermometer to test it and it seems to be very good. This is a good stat if it holds up over time.
