I’ve been using a new free iOS app called PowerCheck for my FoxESS system recently and am finding it really useful. My setup is 42kWh of batteries, 9kW DC and 4kW AC connected solar.
Really liking running it as an always-on dashboard on the kitchen iPad. It's got a large and easy-to-see battery indicator (with animation), and you can see all your live solar, charge, discharge, grid draw, and temperature values on the screen at once.
I set the screen colours to match the kitchen decor so it's a neat part of the room now. Just thought I would share.
Cheers!
