Help with Energy Dashboard setup – wrong units and data from Huawei SUN2000 | Home Assistant | Page 1

Hello everyone,
I’m having trouble setting up my Energy Dashboard in Home Assistant.

I have a 15 kW solar system made up of three Huawei SUN2000-5KTL-L1 inverters connected in parallel. My goal is to track production with peak and off-peak tariffs.

I’ve followed the latest video guide and documentation, but I’m getting incorrect values — showing MW instead of kW, and even after dividing by 1000, the numbers still don’t look right. I’m also not sure which entities I should be using in the dashboard.

Attached are screenshots of my device data for reference.
Any advice would be greatly appreciated!

Can you be more clear what you're looking to fix

#

For the grid consumption I got this message shourtly after - to Change the unit

#

After that I start getting this

#

You seem to be confusing power with energy.
https://www.home-assistant.io/docs/energy/faq/#energy-vs-power

#

Why would a Wh sensor be changed to W? They aren't the same thing.

#

Or is that the integration itself that changed the unit?

#

Well the HA proposed the first one, so I click the Fix issue button

#

I've basicaly created Utility meter with sensor Power Meter - Active power

#

You don't want to use a utility meter on a power sensor.

#

I guess the integration has for some reason changed a previously energy sensor to a power sensor, which is a bit strange, but we can work with that I guess...

#

Ok, so I guess I've implemened the offpeak trariff wrong

#

If you want to get energy from power, that's an Integration (Riemann Sum) helper.

#

Once you have the energy sensor (in kWh), then you can generate a utility meter based on that to split tariffs

#

(I think it's a fairly common misconception that utility meter handles power->energy integration, but it does not).

#

Ok, what is this Riemann Sum, Integration/Helper

tidal fern Oct 30, 2025, 3:25 PM

#

blazing cliff Ok, what is this Riemann Sum, Integration/Helper

basically it sums power (kW) over time to give you energy (kWh)

#

if this is unclear please look up the difference between power and energy. It is critical you understand this otherwise none of this makes any sense

#

Ok I set it up and data look correct but still have some warning in the energy settings page related with my grid import sensor

What I did so far:
Added the Riemann sensor that i found hire with the fillowin settings https://www.home-assistant.io/integrations/integration/#energy

I've also added templete helmper to invert the power meter values because is negative value. settings here

then your template is wrong

#

did you follow Q10 here? https://gist.github.com/langestefan/acbf7e42b15b302e9aacc08663039e57#10-i-have-a-power-entity-which-goes-negative-when-returning-energy-to-the-grid-how-do-i-split-this-into-two-entities-one-for-energy-production-and-one-for-energy-consumption

Believe this is no my case... i dont have energy export/ returning energy. I Only consume

#

how ever when i consume 5000w the power meter netive sensor shows -5000

#

blazing cliff Hello everyone, I’m having trouble setting up my Energy Dashboard in Home Assist...

#

This Image here. The image shows
Active power -1609 W and at this time i was pulling 1609 W from the network

tidal fern Nov 4, 2025, 2:28 PM

#

so why not just use consumption and exported sensors?

keen trail Nov 4, 2025, 4:03 PM

#

The "Energy Grid Import (off)peak" sensors can't be right as the unit is in Watt which is power, not energy...

But you want to split your PV generated energy into peak and off peak? For that, use a utility helper with tarrifs and an automation to switch them.

#

tidal fern so why not just use consumption and exported sensors?

when i used the active power (Power meter native) sesor i get error that the value could no be negative

blazing cliff Nov 4, 2025, 4:14 PM

Yes, prev comments already mentions that.... I'm using wrong sensor in providing (k)W instead of (k)Wh but
The screenshot was from my first try

those sensors are not negative

blazing cliff Nov 4, 2025, 4:24 PM

#

Well this is my first solar integration but this is all the data i have from the Power Meter device - ignore the both "Energy Grid ..." Utility meters that were configer wrong at that time

Okay, but does the integration not have any energy sensors at all by default? Or what is the issue with them? Can you remove all sensors you made and show what you have then?

blazing cliff Nov 4, 2025, 10:56 PM

#

these are the defaut sensors that comes with the power meter
