Thanks mjdyson!
i tried changing the two files… when i use ad-growatt/growatt_app.py at b1e1dc4f66d0ff40c2787df5095f0de930710fe4 · mjdyson/ad-growatt · GitHub file, i break my ability read settings from my selected inverter (using multi inverter possibility) and i can not put changed settings to the server either.
i can though - get serial numbers on inverters in my plant
if i change back to original growatt_app.py file all is working again.
(ive added export limit to the ‘get values from server’ windows.
hope u can point me where i may do something wrong, thanks for your time
