This introduces a PID controller for openHAB. It is based on the work of @george.erhan and @hilbrand . A PID controller can be used for closed-loop controls. For example: Heating: A sensor measures the room temperature. The PID controller calculates the heater’s valve opening, so that the room t…

I’m sure I must be missing something, but I can’t find the CommandItem in the configuration which can be used for the RESET of the I (and D) part? I am running the latest official OpenHAB release 3.3. Here is the configuration that is produced when I add a rule with the PID-Controller template. co…

It seems to be missing in the trigger module definition in the code. Did you try to add it manually to your configuration? configuration: commandItem: MyResetItem ...

Manual addition seems to work. Thanks!

Hi, actually I’m trying to setup the PID Controller the fist time. Setup: Eurotronic Spirit Zwave Heating Regulator, Aquara Temperature Sensor. But every time if I try to enable the rule, I received errors: 023-01-01 19:46:41.369 [WARN ] [.handler.PIDControllerTriggerHandler] - Setpoint item: Te…

Actually it is working, or it seems to. But I can not see any output 2023-01-01 23:18:36.695 [INFO ] [openhab.event.ItemStateChangedEvent ] - Item 'TestPid_Setpoint' changed from 20 °C to 22 °C 2023-01-01 23:18:36.706 [INFO ] [openhab.event.ItemStateChangedEvent ] - Item 'TestPid_P' changed from …

Don’t have time now to go thru setup you have but I would recommend to go and check my how to ‘tutorial’. [image] Set up house heating using Eurotronic Spirit actuators with PID control and "manual" control Tutorials & Examples This will be a tutorial on how t…

I saw this doc from you. but in the first quick reading my thought was that it is not for my use case, because I want to play a little bit with the pid controller in general. I think that the pid controller can be used out of the box. so define input item and output item and it works. nearly it …

I just scrolled thru and I think I know what you are trying to do. I can’t remember it now but I think it wasn’t that simple because of underlying metric casting. Spirit needed an Integer value 0 - 100 while PID provides Float as output. When I was setting it up it wasn’t also possible to limit ou…

If I see correctly, you linked the setpoint Item of the PID controller to the setpoint Channel of the device. The PID controller’s setpoint item needs to be an independent Item, not linked to anything, otherwise the system can behave weird.

yes you’right. I just want to use the output of the pid directly for the zwave eurotronic dimmer. if this will not work, ok virtual items are also OK. But my problem actually is, that I can not see any output of the pid on the logs. I can see changing of debug items for p, I, d and error. but no…
