I think there is some bug related to the Selector Switches. I have spent countless hours on this, and by accident found a way to make it work. Meaning this must be some bug.
If I make more than a couple Selector Switches, the next one appear with no data. Like 40310 below. I have the exact same settings, because I copy the working Switch. I only change the adress.
Scanning for the 40310 Modbus adress with CAS:
Reading the bit with digital input:
Selector Switch is still not working:
If I however enter ANY digital tag in Feedback.
Then the Switch will show Auto, as the digital input was 1.
But if I remove the Feedback, the Switch still works.
And now I can toggle the switch as expected.
