[BUG] VE.Bus System node - Switch Position

[mr-manuel]

Describe the bug The VE.Bus System node with the Switch Position measurement is not setting the Switch Position anymore for a MultiPlus II with the latest version 1.4.27. When I revert back to 1.4.26 it is working.

To Reproduce Steps to reproduce the behavior:

1. Insert the VE.Bus System node
2. Select the Switch Position measurement
3. Send a value to it
4. Nothing happens

Expected behavior The value sent to the node should be set.
