Sending setMaxOutput to MQTT #28

Hi,

I would like to try this setting to reduce the power of the inverter in case of a negative energyprice when my battery is full. In MQTT Explorer I tried to send this:

What am I doing wrong? What is the syntax for the MQTT message? I can not find any documentation in the code.

Let me add @joe288 as he added this functionality to my original code.

Since when is this in the code? Because I think it's not in mine...

Hello, the value is simply transferred in decimal. From 1-100%. image You can also switch off the Growatt completely via setEnable. image

Like this: image I get not any confirmation and the Growatt is still producing more then the limit. Is this implemented after 20 aug 2022?

this was added to the master branch of nygma2004 on 10 December. image

Thanks! So it is not in my sketch yet and that's why it won't scale down when instructed to. I cannot update the sketch since Arduino IDE is bugging me big time but that is not part of this issue. I get lots of errors for a FastLED and a lot more of definitions from certain files he cannot find.

Issue can be closed and thanks for your help!
