Describe the feature A clear and concise description of what you would like.

Envoy

Home Assistant

Envoy has a rather new function called zero export function. Is that something that can be implemented. I think it can be used instead of the production function, which doesn't always work well. In case of negative prices, zero export appears to be react faster.

Hi @Michielgrs. For some time already you could manually load a zero export grid profile, this is possible via the set_grid_profile function call in this integration. I read on some forums that from firmware 8 Enphase also has a zero export function tied to dynamic energy prices. As soon as this firmware hits my Envoy I will take a look.

Important detail, you noted down that you have an Envoy metered without CTs installed. For anything zero/limiting export etc you need to have CTs installed for the Envoy to measure your realtime energy production/usage. Without CTs this functionality will not work.

Hi @vincentwolsink. So the Envoy Standard users won't be able to use the zero export functionality in the future? Thats too bad, because I know my real-time import/export in Home Assistant via the P1 port (basically the same information the CTs provide directly to the Envoy Metered) and it would be great if I could adjust the production of my 18 Enphase micro's dynamically via Home Assistant.

@rogervdh Correct. This is how Enphase implemented things. All logic is internal to the Envoy and it doesn’t accept any datasource from the outside.

I also don’t see anything like you wish for happening soon, since Enphase provides zero support to any local api or opensource project.

I can see the option to limit the production in the enlightenment manager Would be great if this is implemented in the intergration.

vincentwolsink commented 2 months ago

I will implement this if (I really hope so) and when a local endpoint for this functionality is known.

@vincentwolsink the zero grid export profile is not available anymore. Any chance to set "Power Production Limiting by Gateway" via this home assistant integration?
