Control your Anel NET-PwrCtrl products with this app. It uses the UDP interfaces the products provide to switch sockets.
Your phone/tablet will either have to be in your wifi or you need to connect a VPN before this app can work.
I strongly recommend against a simple port forward from your router to your PwrCtrl as this will let your username/password go unencrypted over the internet.
Even though I have been kindly allowed to use the company's graphics and product names for it this application is not provided by Anel Elektronik, but is a private project.
So far I was only able to test this application with NET-PwrCtrl HOME devices. The interface will also show 8 sockets instead of only 3. That's because the UDP shows 8, even if there are only 3. I decided to implement it that way nonetheless so it may work with other hardware variants than the HOME edition.
