Change entinity in Node-RED or IRL

Hello.
I´m new to node-red so this might be a noob-question. Sorry in advance.
The case is following:
I have a manual setpoint which controls the heating setpoint in a room. I also have a “helper” entinity in Home Assistant that adjusts the same setpoint. (The setpoint tagg is adjusted on BACNet on the same priority,)
What I´m trying to do is when I adjust the manual setpoint, I want the feedback to adjust the setpoint on the same entinity in HomeAssistant.
I guess there is an easy way to do this, but I have tried a couple of blocks, including “call services”. But just ending in an never ending loop.
The only thing that works the way I want is to use a dashboard numeric-block. But I want to use my helper :slight_smile: Does anyone have a quick-fix for this matter?

Glad for any tips :slight_smile:

I’m not familiar with your type of climate control. This is how you would use an input number and a climate entity in HA to change the temp.
