Thanks for sharing @matfroh .
I’ll do mine - I’m sure it’s useful for the not-so-advanced HA-user. Although, like you, I’m not fully there yet.
I’m using the (cloud based and thus 15 min delayed) Solar Edge values to calculate my Tesla charging amps (can’t do the modbus thing, according to SolarEdge documentation).
Start charging based on P1 value, stop charging based on (almost) no more sun. Still a work in progress, but it’s working quite well already (for my requirements and skills).
All this is based on what’s been said in this thread, so many thanks for that, everyone!
Next up: using the P1 value for calculation, but I’m having a bit of trouble combining the code with the math 
(plus time to look for it a bit more).
To be clear; I keep KISS high & mighty (I don’t want to copy paste large chunks of python code I don’t understand fully). These are all automations and 1 simple script (mentioned above).

I’m pretty sure surrounding the code above by an “IF” ( calculation < 0, then GO, ELSE Charging Amps = 0) is a dirty solution, and that’s what I’m going for, for now.
I’m using a few helpers
And I also have a few other automations which I won’t share because of the fact they’re not relevant here (stop charging when plugged in, stop charging when no sun and < minimum charge,…)
). Anyway I’m still not having much luck with this.
