Calculate ROT out of SK compass data in Node-RED
Hey everyone!
I'd like to calculate ROT out of my compass data but can't figure out how.
I've stumbled upon a forum post mentioning the "calculation" tool in Node-Red but I'm unable to find it. Post: https://forum.openmarine.net/showthread.php?tid=667
May someone help me with this or know another way to get ROT out of my compass data?
Thanks already!

hwt901b-plugin error: Resource temporarily unavailable
Hey everyone! I'm having some trouble with my WIT IMU as I won't get it to work with signalk. I already checked the device in the calibration software of the manufacturer it's running perfectly fine. Though I have selected the right port it cannot lock on it. I'm currently using a Raspberry Pi 4 B with the latest stable of openplotter headless and all installed software is up to date. I will post the debug logs below. Thank you already for taking your time!
