Homewizard WiFi Watermeter

I just bought the home wizard WiFi water meter after getting the P1 meter and energy display. I’m trying to set it up but it always fails on the set “Adding to your home” and then says something is wrong with the WiFi configuration, although the light is green on the water meter and the WiFi connection step is done.

I have tried everything they tell you to do on their website. Anyone else encountered the same issue and how did you fix it? Now the device is not usable cause I can’t add it to my home

Does anybody have homewizard watermeter installed on non-officially compatible watermeter? I have one that has literally same clock-kind round scale the meter requires but is not listed between compatible devices. I guess this is going to be only a problem of mounting it properly?
