When changing between the alpha and final version of the [SolarPanels](https://apps.athom.com/app/it.diederik.solar) App (or vice versa?) Homey decided to delete _all_ my production data because they were “not compatible”… 😢

Is there a way to upload historical data?

Additional info:

- I can get the historical data from the Growatt website
- I wrote the driver for my particular (Growatt) inverter for the SolarPanels App
- I want my data back, so I’m motivated to spend time/effort on writing code for uploading historical data
