hi everyone,
I have just setup a new HA installation in my new house and started monitoring electricity consumptions.
Context: i have a smart meter with a Energywizard P1 dongle, a full electric heath pump and solar panels.
I am using the sensor Energy import and Energy export as consumptions and return, respectively.
Unfortunately I don’t have yet a sensor for monitoring the solar panels alone (should come soon when i will have access to the huawei kiosk mode):
I have then added the heathpump and other devices as individual devices, but i have noticed that today I have negative untracked consumptions also during the night.
My interpretation is that during day lights, untracked consumption would represent the excess put in the grid vs what i am actually consuming (I might be wrong thoug):
I have checked the individual energy entities of the heathpump and other devices and they are monotonically crescent, so I don’t understand that negative consumption at night.
Any idea?
This dashboard is kind of weird to set up at first. But once you understand the basics, it all starts to make sense.
Untracked consumption, whether positive or negative, is caused by things not being nested properly or due to calibration issues between sensors. You should have one main power sensor, and then all other sensors should be nested under that. If you go to Energy Configuration from the Energy Dashboard, hit Edit for each of your Individual Devices and make sure everything has an upstream device attached to it. For example, if you have your main grid power sensor, everything in the first tier below that should have the main grid sensor as the upstream device. If you have a smart plug off of one of those circuits, the smart plug would have the upstream device set to that circuit, and the upstream device of that circuit would be your main grid device.
The solar should be nested under your main grid sensor and would then show as negative power draw.
For example, my main grid input (address is there, so redacted) is labeled “Main Panel Power” and my house has a subpanel off of that, so Main Panel Power is the upstream device of my House.
hi, thank you for your answer!
I have tried, and i have added the Energy Import sensor coming from the P1 port to the individual devices, and added it as root of all the other devices.
but it didn’t seem to do the trick:
That means the chid devices you have added are using more energy then their parent device. Which is of course impossible. You have not configured the child-parent device relationship correctly.
Only make a device a child device it its power is also measured by an upstream “parent” device.
It does not have to be a child of something if it has no other measurement upstream.
Thanks, indeed, I compared the usage of electricity with the one coming from the P1 port and my energy supplier, and the consumption during the night was way less… so it looks like the heathpump is showing weird consumption values…
Or I am misinterpreting the meaning of those entities.
