Hello,
I have the same problems also.
When high load is needed, the measurements are nearly ok, but in “idle” Mode everything is worse.
I’ve had a chat with the support yesterday, but no results for the problem.
Is there a way for a factory reset? So I can try to setup everything new?
What I have also seen, ist that Main B has got less Amps. A and C are O.K. with the offical Powermeter, but B is less from 0.4A at 300W and up to 3 Amps at 2kW…
I’m very sad, but I think I will return the paket and try something different…
HomeAssistant is working well with the Vue…
