[Solved] How to allow a channel to be selected from a custom function/controller (or autotune PID)?
If I have a device with multiple outputs like the PCF8574, I can select an individual channel from the device from some areas of the UI, like a conditional action, but I can't from other functions, like the Autotune PID function/controller. I'm asking because I am trying to write a custom controller and I can't find a way to select an individual channel from the setup screen.
To reproduce, add a PCF8574 output. Add an autotune PID controller. Try to select the output device from the setup menu of the PID autotune. The only option presented is the PCF8547 device. If you do a similar thing with a conditional controller, you can select an individual channel from the PCF8574 device.
