I had some time and created a backend where you can send data from Fronius Inverter via push service and show it on web page. Simple proof of concept, no pretty graphics. This is early alpha version of Solar Api monitor
How it works
register at: http://solarapimonitor.com/api/#/register. email and password is send from Fronius inverter unencrypted, so please use unique password (at least 6 characters).
then login at: http://solarapimonitor.com/api/#/login to make sure email and password works
Setup push service in Fronius settings as on pictures. You can set any interval, but please do not use 10 seconds, it may overload my server in case of more users. For now it is for free. Enjoy.
