#How to set up self-consumed solar gauge

I had solar panels set up last week which is using an Enphase IQ Combiner 4.

I added the Enphase integration to my HA and in the Energy dashboard I set the following:

Electricity Grid:

  • Consumption: Envoy Energy Consumption Today
  • Return to Grid: Envoy Energy Production Today

Solar Panels: Envoy Energy Consumptino Today

As best I can tell, that seems to be showing that I'm basically exporting 100% of my generation, and then it's calculating the home usage based on consumption - production. However that means it's missing whatever energy the house is consuming immediately on generation.

When I log into the Enphase cloud dashboard I can see that it tracks Imported, Produced, and Exported, which I think would allow for the self-consumed data to work. Is there any way to access those values from HA?

For the energy dashboard, don't add the same entity twice. That's always wrong.

Does the Envoy also measure all the incoming / outgoing energy to the grid? Aka, it needs to have a CT on the line from the grid. Can you show all entities of the Envoy?

There are 121 entities, although most are disabled.

These are the enabled entities for the Envoy. Although there is also one for each inverter.

the consumption is not needed for the energy dashboard. that doesn't track importing or exporting although it can be inferred from it.
Look into the utility meter helpers (there a many tutorials online that can help). One for each import and export. It can be setup with multiple TOU rates. Using an template you can setup import and export energy using the difference of consumption and production. an automation can be used to point the difference at the appropriate utility meter tariff based on time. Giving you something like this in the dashbaord.

So I assume the answer to my second question is "Yes, it have CT's around the incoming grid supply"?

I think you will need the 3 lifetime sensors:
Lifetime production = Solar production
Lifetime net energy consumption = grid import/consumption
Lifetime net energy production = grid export / return to grid

Utility meters as @vernal ridge mentions are only needed if you have different tariffs and want to track that. But really, before you start messing with that, understand what your sensors actually are.

Ahh, maybe the issue was that I was using daily numbers. Switching to lifetime seems to have fixed it. Thanks!

Day sensors can work but have the downside that if HA is temporary unavailable and a sensor resets (aka, new day) you miss info. Where as with a lifetime sensor it's just pulled in a bit later.

But the biggest issue was that you had the same sensor set for import / consumption as for PV generation. That's not correct.

Just FYI, the enphase daily sensors have issues, use lifetime sensors with the energy dashboard. If you have feedback on how/where to improve the docks let me know so we can improve those.

I think once I figured out what I was trying to do, the documentation was plenty good. There's just so much information in there I got overwhelmed reading it all instead of just going to the Energy Dashboard section
