RdPower 4+

Previously I had spent some hours over numerous days trying to get this App working with my iPhone 8 with no luck.
It seems it couldn’t identify the server IP address properly, thinks it’s 0.0.0.0 so failed at the Distribution stage.
There was some communication occurring between the RD6006 and my iPhone so I know it’s not a hardware issue. I have checked my modem for the mentioned compatibility settings, but nothing matches the name descriptions.
It’s a shame because the PSU seems to be quite good so far. The website doesn’t have an English option so no help there, and the YouTube videos have the comments disabled...
Hopefully someone will see this and solve the problem => see update below...

Edit V1.1.5: still doesn’t identify the modem/router IP. It still shows 0.0.0.0 it might be good to allow the user to set the server IP manually?
I did manage to get a false success message, but it didn’t connect to the GUI. Please keep trying!

Edit V1.17: It works! Thanks for your efforts. Note there is still room for improvement:-
1/ the voltage graph doesn’t show the actual voltage at all times => Found out the graph is interactive and was stuck at the start! Swiping left got it going again.
2/ the address set in the control centre doesn’t seem to affect the Server Address (my iPhone IP), nor the device IP which is shown in my Network Analyzer App. What does it do? Same for the Address in the RD6006 menu. Should these be set the same? A better instruction would be good.
3/ the set values M1 - M9 can be controlled via the callout icon, but the On/Off output behaviour is different when setting a higher/lower value. It would be good to have a consistent behaviour.
4/ solving the above 2 items would add another ⭐️

Not able to find any wifi network which my iPhone 11 Pro Max is connected too - field just empty. With an iPhone 5 S network can be selected and RD6018 show the IP but than the process stops with an error.
