The prior epever app was functional but extremely clunky. Most annoyingly, it required manual refreshing rather than giving realtime data.
The new Pair app is much better. Looks fine and gives real-time info:
The 2nd pic shows LFFP-specific setting for low-temp cutoff of charging and discharging (standard temp probe required). My Rebel Batteries LiFePO4 has BMS cutoff and the batt sits on a warming mat, but a third safety is welcome. I don’t have the funds to replace the batt any time soon.
