@DaChNic itās done. You can install the latest version by clicking on 2.8.0 above and press the green install button. (no need to remove your powerview app!)
At this time I have to restart Homey every few days because this app just stops working. Last times this happened I also restarted the Powerview hub but Im not sure if this is required to make it work again.
Nothing has changed in my network, I have no idea what I can do to prevent this.
Maybe this will help others, so hereās what fixed it for me:
In my case, the Powerview hub was connected via wifi, I found an option in the hub to fix the ip when connected with a cable so I did that and set the ip there (even though I previously already fixed the ip in my router and Iāve never seen it using a different one than expected).
Iām not sure using the wired connection or setting the option in the hub did the trick it but at least it works now and Iām not touching anything anymore unless it breaks again
