Hi Vincent,

I’ve got a question about the Solar Forecast. I’m looking into which app/device to use, but to my surprise my Growatt inverters are already shown there. In the description it says _Device with meter\_power.tomorrow / .today_. Are these the only capabilities that’s looked at for Solar Forecast because I wouldn’t have expected to see my inverters there (I will ask @Gruijter which capabilities are actually used in the Growatt app)

I’ve used the Power by the Hour app to create PV monitor device which is a device to Forecast Solar, but those devices don’t show up. I don’t know which capabilities this device uses, that’s also something I will have to ask Robin.

Thanks!
