It's really fun and easy to do the setting with nice graphic interface on phone. The product gives much better accuracy compared to conventional timer relays. I get extra features such as diagnostic and password protection. Now I can know the status of relays and even do debugging on outputs. All wiring and timing diagrams can be found in the app too. Furthermore, I can feedback instantly my questions through app and get support in.This is the product I looking for! What's more? The app is free of charge!
