Just got my Cerbo GX set up in the hut and it's pulling data from the MPPT and the multiplus fine. But I'm wondering if I'm underusing it. Currently only monitoring battery SOC and PV input, nothing else.
Thinking about adding a temperature sensor inside the hut — it gets proper cold here in winter and I want to know if the LiFePO4s (Fogstar 200Ah) are dropping below the safe charge threshold overnight. Worth doing or does the BMS handle all that anyway?
Also seen people wiring in a energy meter on the AC side. Is that straightforward on a small single-phase setup like this? Only running about 800W peak load max — kettle, a few lights, small inverter fridge.
What sensors or integrations have you found actually useful day-to-day vs stuff that seemed clever but you never look at?
