Anyone know where I can locate my the PlantID from the legacy or beta portals?
PlantID

I believe it's just '1'.
Assuming you only have 1 system configured.
Well that was simple, and simple is best.
😃

Mines 118X so not sure its always 1. And I only have 1 plant.
I got mine from the API:
https://www.givenergy.cloud/GivManage/api/plant/getPlantList
Not aware its in the portals anywhere buy someone will point it out if it is.

Could well be I'm talking rubbish then. 😂

Haha it may well be now, stuff keeps changing all the time.
Take it your playing with the api? Can't think of a reason to need it outside of that to be honest.

I was definitely wrong (not the first time). My plantID is a four digit number.

I've tried before and failed but this post made me try again to get the battery SOC in to Home Assistant. Finally managed it. 😃
