I bought two pieces I am already using great quality

My use: Automate the heating dab a aquarium. Temperature measurement is not only very reactive but plus is extremely accurate. It is of course possible to act on the controls of the device directly on its function keys but the sequence can be somewhat complicated at the beginning. The big strong point for me is remote control by application, when the device will be recognized in your WIFI and you will have installed the application on your telephone, you will have at your fingertips tous the parameters as well as the monitoring of the temperature curve. At that time the uses will be A child’s game.

Perfect operation. Cool design.

This works perfectly and I am very happy with it- BUT the “Line” and “Neutral” labels are reversed. If it is connected as labeled it can cause a dangerous condition. Please see attached picture and connect it like this. I will be ordering more of these. I hope the maker can correct the labeling error.

Great transaction! Thank You!
