EARU EAKCB-T-M with energy measurement BL0942 shows 0 watt and 0 PF power factor at load change.
I bought 2 pieces of these switches with measurements and uploaded OpenBeken. They are connected to a small off grid installation, one at the input and one at the output.
One of them - the one on the input is showing the power and PF measurement wrong after a load change. I calibrate it on a low load - 58 watts, then all is fine until I increase the load, then it gets off. Same when I calibrate on a higher load, when I reduce it shows 0 PF and 0 watt. Overall on a low load it's power factor is very low through the inverter, at 50 watts at 'rest' it's 0.15 PF, 1.6 A and 58 watts.
Generally strange, as I've done the same with everything on the output and there are no such problems, but there is generally a much better PF of 0.4 at 50 watt.
I don't know too much about these openBekens, are there any commands what I've missed that might help?

I was calibrating on a higher load last night - 300 watts and as soon as I turned the load off the PF dropped to 0 and the watts also dropped to 0.
