    I have the same set up as you 6kW south facing system and a regular 6kW Solis inverter. I to had the same problem as you as I couldnt see how much I was exporting or using, the Solis app also is not that great. I decided to go down the Home Assistant route to log and monitor my system.

    I put in a ShellyEM to log my main ESB incomer and my PV feed. This will show you how much you are importing and exporting and also having it on the PV feed will give you live data on your PV. HA also has a dedicated energy dashboard that gives you good data. IF you want to get into the details than you have Grafana in HA as well that can you you fancy graphs like below

    Amazing this gives me way more confidence to go for the Shelly setup! I'm going to order one today. Any reason to go for the pro version over regular, only €10 in price difference:

    The pro version says 'Photovoltaic ready'. Prob just sales pitch though
