Dual Growatt sph inverter export control using Shelly ct clamp and solar assistant with homeassistant

Good day I’m after some advice please.
I have 3 inverters at my address 1of those is a 4kw that just does its own thing and 2 of them are Growatt sph3600 inverters. I am allowed to export up to 8.7kw back ro the grid but at present I have no way of limiting that export without using an export limit on an inverter. That all sounds good but the moment I turn export limit on to any percentage it clips the output to zero because the ct clamps off bothe the sph inverters are on the same live tail and read what they and the 4kw system are doing.

To get round this I was advised to get solarassistant and a shelly em gen 3 ct clamp and connect them. I’ve tried that but have since learned that the Shelly clamp cannot be connected to the solarassistant but it can be to homeassistant.
Basically what I need to do is read my export power using the Shelly and cr clamp and use a program to reduce the export output on one of my sph3600 inverters.

Would this be something simple to do using homeassistant? I’m starting to lose my mind with all of this and looking for an easy way of setting something up and easy to control.

Sorry for the long winded message but I think I’ve explained my situation there, best regards

Steve

Any ideas, im stuck
