question

Hello.

I know, questions like this have been asked already, but not quite like mine, I guess. Okay, I have been able to create a simple flow in Node Red to get my SOC out of my Daly BMS and I can read it via html. It looks like this:

For information, I can read it out with

 https://venus.local:1881/batt 

However, now I need to set the SOC. Somewhere I read this is not possible with Node Red but I am not quite convinced. As I understood it, others have made it, but I am not sure. Maybe it's possible with a workaround(?)

So, does anybody have a solution on how to set the SOC on a DALY BMS (preferably with Node Red)?

PS: Just in case, someone wants to check out the node above:
