- Platform information:
- Hardware: RasPi 3
- OS: Openhabian
- openHAB version: openHAB 2.5.10 Release Build
I have an RasPi running OpenHabian and an arduino, which I use for controlling inputs and outputs.
I have a button connected to the arduino as well as a LED. Pressing the button shall update an item in OpenHab. This update should lead to switch the LED on or off.
The item is configured with state topic Button1/buttonState and and command topic Button1/buttonControl.
When I press the hardware button connected to the arduino I can see an update of the item in OpenHab. Also, when I update the item manually I can see that the arduino gets the notification as well. So, basically evertyhing works.
But it seems to me, that the item doesn’t automatically send a command when it gets updated. I somehow expected exactly this behaviour. Is this something I can configure somewhere?
Everytime it receives the message that the button was pressed it should send a command to every subscriber that the button actually was pressed.
What am I missing here?
