Hey, I am currently trying to narrow down my untracked energy reported, at least for the larger consumers in my house.
I am basically using a combination of KNX actors, smart plugs and math (for consumers with linear consumption when turned on).
I basically still have a blind spot of approximately 50-60 watts when the house is completely idle. This is from some standby consumptions, consumption of KNX bus etc.). When we are not at home, I recognize this blind spot of untracked energy to increase, especially when we’re having good weather and our solar panels are producing energy.
I am using a GoodWe GW6.5KN-ET inverter, which is also integrated in Home Assistant, but I am really struggling to get a hand on the inverters own power consumption. The integration does not provide an entity for that.
I tried to use the difference between Total Power entity and PV Power entity, but this difference sometime becomes negative, so this does not seem to make real sense.
Anyone with a compatible setup and an idea on how to properly allocate the according share of untracked energy to the inverters self consumption?
