I now have a timer from Hager (EGN103). I actually need additional smartphone control, is Shelly Pro 4PM the right replacement or are there better options?
These are different applications. The Shelly can do the same thing as the Häger, as long as it's connected to the Internet to get the time! But more precisely, the Häger is a true 3-phase switch, whereas the Shelly has 3 channels... On the other hand, the Shelly is for home automation. If you're an initiate, you need to find out more first...
