I was not able to get either of the locally-polling SMA options to work. The SMA tl option that uses Sunny Portal did work, but updated its figures only very sporadically.oepi-loepi wrote: ↑Wed Mar 23, 2022 11:27 pmIt should work on the sma.Henri wrote:Sorry, I don't have the solar panels yet, but I doubted or the solar panels work with this app. But based on your answer i think so.
I can't get local polling to work because my SMA Sunny Boy 3.0 only allows access to its web interface and API over TLS. Even though the solarPanel app has an option for connecting over https, it will not work because it won't accept self-signed certificates which the SMA inverter uses. I tried adding the certificate to the local certificate store on the Toon, but even then it refuses to work. Even curl will not connect even when I forcefully provide it with the inverter's certificate through the --cacert option.
I ended up setting up a reverse proxy to connect with the inverter over TLS which is itself accessible over plain HTTP. When I direct the solarPanel app to this plain http proxy everything works as expected.
