Hi, I have a Shelly EM 1 to measure the power consumption of my airco. The airco is on a dedicated circuit breaker. Also I have solar panels that are also on a dedicated circuit breaker. See picture. When the solar panels are producing a lot of energy I notice that the Shelly registers returned power around 5 watts. The same measurements are also in the Shelly app visible. So it’s not a Homey app issue. Can some explain how this is possible? I know it’s not a dedicated Homey question
