Combining old Enphase data with new

[Jasper8472]

When Enphase stopped working a while ago I resolved to a HACS integration. Enphase (DEV). That resulted in two sets of solar panel data.

The sensor data from the original integration is still there and I use it to get an estimate over a longer period. (monthly, yearly, etc.)

Now the original Enphase is fixed I want to return to that integration without losing my sensor data from June, July and August. Is there a way I can add the DEV data to the old data?

See the answer I gave in another post on this forum.
First part of the answer:

Switching from Enphase Envoy (DEV) back to core

Decided to bite the bullet and these are my findings so far; First create a full backup (I waited until the energy dashboard got it hourly update and made a back up straight after that). After the back up , follow the steps in the second post (delete the integration, restart HA…) The Enphase solar panels will be discovered automatically and a notification is given. Click the ‘Show discovered device’ (or something) in the notification and click ‘Configure’ in the integration screen where the En…

Second part with additional information about ‘settings’:

Switching from Enphase Envoy (DEV) back to core

That did the trick. I added the Enphase integration via the core integration like in my previous post. The entities that are created are something like; sensor.envoy_**123344567789_**lifetime_energy_production sensor.inverter_12233445567 etc. I compared these with the entities that I had when I had the DEV-version working. I found out that I had to change the entities to the following; sensor.envoy_**enphase_s_**lifetime_energy_production sensor.**envoy_enphase_s_**inverter_12233445567 A…
