The AC loads bar at the right side of my Brief screen randomly alternates between the correct length, corresponding to the wattage shown, and a shorter bar, corresponding to a value estimated to be about 400 Watt lower. The bar length changes every few seconds, while the power consumption and the Watt number displayed stays nearly constant. I’m not sure when this started but I don’t think it behaved like that when I first started using gui v2. I noticed this behavior while running v3.52~2, but reverting back to the previous v3.50 version doesn’t make a difference. The last thing I changed was turning off Auto-ranging for the gauges, but turning it back on doesn’t help either.
I’ve made a screen recording of the behavior: video
The grid setpoint is 0W with an external current clamp connected to the Multiplus II.
The PV inverter is AC coupled and connected via Modbus.
