SE battery over modbus

[Pocster]

I was (expletive deleted)ed off again !

SE cloud constantly failing to execute battery schedule.

So bit the bullet and with my best mate ( chat ) got it working in home assistant.

At the moment still time based - but working !!!

Then we can get far more advanced as to when it discharges specifically to Tesla !

Awesome stuff ! I owe chat a good few drinks !!

The SolarEdge modbus interface is not great - presenting scalers as value + exponent in separate registers is inherently racy and can create large glitches in readings. I extensively hacked the Loxone integration to work around this -- basically read multiple registers in a single atomic 64-bit register read, then crack apart the words and recalculate the correct values.

BUT it's still better than their very low frequency cloud API.

 

What do you mean by  At the moment still time based?

Currently ha is just doing time of use as the cloud rubbish was attempting to do before . Later I’ll make it based on use not time .
