Ikea symfonisk and servo (nitro engine future project)

Hello everyone, I am planning on making a future project which I need some advice on.

One part I am a little unsure about is adjusting the throttle, I plan on using a servo to adjust the amount of throttle. I’m not sure how I am going to use the servo, but I think using tasmota with a nodemcu is a good way, but I still don’t know how to set up a servo in tasmota and somehow link that to the Ikea symfonisk knob (below).

The other part is going to be using the Ikea symfonisk knob to adjust the position of the servo. The servo only needs to travel a certain amount of distance and I need to somehow make it so that if I keep turning the knob, the maximum degree the servo should be at for example is 90 degrees. This would have to be set at both ends eg 20 to 90 degrees.

I also want to use the knob to adjust the brightness of my lights only when the nitro engine is off, but when the engine is on I want the knob to adjust the servo.

How would I go about doing this?
