Hi all,
I have a Bosch heatpump (wlw196i) with ems-esp gateway connected to my home assistant via mqtt. It works nice.
Now I am trying to make sense of the numbers.
Most important, I would like to obtain the power consumption of the device to be able to have the device as a separate consumer apart from my house power consumption,which it is currently included in.
I can get only one power consumption from the ems-esp, which is “compressor outlet power”. However, that is in the order of 8 kW. The entire heatpump should not consume much more than 2-3 kW. Therefore, apparently the “compressor outlet power” should be the actual heating power downstream of the compressor, like (heat from ambient + compressor power) in a ratio of 3:1 according to the current COP.
Has anyone been successful in calculating the actual power based on ems-esp readings?
I have a couple of energy readings, however they are only in discrete 1kWh steps. Seems to be a bit coarse for a derivative sensor, especially if it is summer and only hot water is produced with 1-2 kWh a day…
Cheers!
Has anyone be
