Hello friends. Since i am working with MODBUS and wrtting to subregisters, i have already had my challenges with it. Unfortunately i faced a problem again but the thread is alreay closed. If someone is interested, here is part I: Write to subregister via Modbus and bufferparser
My problem right now: I reorganized my dashboard a bit. To conrol my dosing pump is use dropdown widgets now instead of a form. I now want to write to an adress that is "devided" into subadresses (bits) (see part I).
Since i swicthed to dropdown widgets i am not able to control my pump (subadresses) correctly.
My flow is very similiar to the solution of part I, but somehow i am missing something that it doesnt work.
The problem: My changes in my dashboard arent correctly assigned to the subadresses.
Here is the flow:
