Autopilot not recognized by B&G Zeus 3s

[sberl]

Tried this out with my RPi based signalk computer and Zeus 3s MFD (SW version 22.2).
I could control the Raymarine autopilot with the RPi keyboard, but I could not get the Zeus to see any autopilot and make the autopilot control widget appear.

[htool]

I have the same MFD, so that shouldn't be the problem. What does the script show when you run it from the command line?
