Unable to add homewizard p1 meter to home assistant despite being visible

Hi Guys, thanks for helping!

I run home assistant on a raspberry pi 4 and have the homewizard integration installed. Through this integration, I am able to add my homewizard energy socket succesfully. I also have a P1 meter that is seen by home assistant as a new device to be added. If I try to add this P1 meter, I get an error that the device cannot be reached.

Taken steps:

  • Re-install homewizard integration
  • Rebooting Home assistant
  • reboot homewizard p1 meter
  • Factory reset P1 meter
  • Verify that ‘local API’ is enabled in the P1 settings in the homewizard app

None of these steps have worked. I would very much appreciate help since I want to build a dashboard that shows my energy consumption with relation to the outside temperature to see how well my house isolates under different temperature circumstances.

Once again, thanks a lot for your help!

I have the same problem. I cannot install P1 monitor.
