Imported power and energy entities factor 1000 wrong

[DeZeeg]

Description

EVCC is installed on home assistant as add-on.
As my Enphase Envoy has an integration with home assistant, I use those sensors in evcc as the source for grid and solar.

Values for current are correct. Values for energy and power are a factor 1000 too small:

grid - energy
evcc shows = 8.7 kWh
Home Assistant sensor shows 8.732 Mph
grid - power
evcc shows 0 kW
Home Assistant sensor shows 0.245kW

It's not possible for me to validate if this is specifically related to the Enphase device in home assistant.

Steps to Reproduce

1. install EVCC on home assistant
2. use UI configuration
3. setup grid: manufacturer = home assistant / power entity = Enphase envoy entity sensor

Your sensors need to provide the values with the unit that evcc expects. This is W for power an kWh for energy.

Your sensors need to provide the values with the unit that evcc expects. This is W for power an kWh for energy.

I understand, but the HA documention shows that those use the same unit for power. For energy, there is indeed a mismatch.

https://www.home-assistant.io/integrations/enphase_envoy

[mfuchs1984]

You should provide an evcc trace log with homeassistant and site on trace, so we can see what is coming in.

[mfuchs1984]

Hmm, what else does the selection offer? Can you set everything on trace?

"unit_of_measurement":"kW"
"state":"-0.005"

It reports kW. So you need to create a template sensor in homeassistant that converts it to W. At the moment, it's slightly negative, but this might be because there is no sun, you should look at it again when it's sunny.

Merged inti nightly, can be tested tomorrow

[DeZeeg]

facing issues with setting up nightly version. Raised #26608

[andig]

You can edit the template right here in Github. No need for nightly.

[DeZeeg]

sorry, I'm really a noob and have no clue what you mean.

[DeZeeg]

Tested on version nightly.20260111-a19e16e
Values for power and energy are now imported correct from Home Assistant without using template sensors.

[mfuchs1984]

The lifetime energy sensor reports "unit_of_measurement":"MWh"
