I’m trying to use PID Controller Automation (PID Controller Automation - Automation | openHAB) to control the window opening mechanism. I have a Dimmer type Item that is responsible for the degree of disclosure. I configured the PID Controller parameters and specified the required Item in the “send command”, but the window drive does not respond to the PID Controller in any way, and in the logs I see errors like

[DEBUG] [ule.handler.ItemCommandActionHandler] - Command 'null' is not valid for item 'L_window_TargetPosition'.

As I understand it, for some reason the dimmer item does not match the type of data being transferred. But how then can I connect this automation and my drive? But when I connect the dummy item with “number” type, it receives the data values from PID controller correctly. What am i doing wrong?
