Turn on Load Relay (DO relay) #80

Open Kawobei opened 1 year ago

Kawobei commented 1 year ago

Hi, I do not understand something from the documentation. Both addresses for Total PV generation 13002 and Load Adjustment 13002 10 Load 1 adjustment mode 13002 U16 0: Timing mode; 1: ON/OFF mode; 2: Power optimized mode

How can I add this as a switch? I have my hot water hooked up but I would like more complex automation rules than the inverter allows. Regards, Brenton

Louisbertelsmann commented 1 year ago

Should still work. Those are different types. If you look at "Inverter start stop" and "System state" it's the same thing.

Kawobei commented 1 year ago

You are correct, I got it working last night (very happy) my guess was the holding ones are different even though same numbers. Not sure if you want the code? I dont know how do pull/push stuff.

Louisbertelsmann commented 1 year ago

You can Post it here. Maybe someone will also find it useful. I might Do a pullrequest.

note: If you change a value by the sliders, it will take up to 60 seconds until the state variables are updated

Unfortunately, I could not find a way to "force update" modbus registers, yet...

Would you mind checking this for me, since I don't have anything connected to my DO relay? just copy the content of modbus_sungrow.yaml

I did try today and it didn’t work. I am in the process of trying to identify which line is the issue. Looking at the changes in a compare I don’t really see what is the problem. I’ll spend some more time over the weekend.
