@vansman it starts working again. After a few days the information is returned at the screen. No idea why.

@Hoaxr Mine is also stopped working. Try to set the url in whitelist but that seems to do nothing with it.
When copy the url in the browser i get the information on my screen so the url is right and working at the rasberry.
Only see the header on my mirror no data.

@Hoaxr Thanks! It works.
I added some dataRequest’s in Homewizard.js. (current voltage - total export)

What i like to see is a daily use of energy. In the API list i see a timestamp but my coding skills are very low.

I also tried to add the data from the watermeter. This data comes from another local ip adres. When adding the dataRequest.active_liter_lpm the display returns a Null number.
So tried add an second ip in config.js but then the first ip is ignored, so all electricity and gas return a Null number. (the value of the watermeter then displayed correct.)
But a nice start that i have some info on my mirror.
Thanks so far

I like to see some data from the Homewizard P1 meter on my mirror.
There is an local api which can be turned on in the app.
In a browser i get the current data with http://IP_P1_meter/api/v1/telegram
Unfortunately my coding skills are not that great.

Hope someone like to create it
