I’m trying to make a smart blinds control system , i built up my system using esp8266 wifi module and burned the software image to it , then connected it to a servo motor .
Then i checked it using mqtt broker . i published to the topic and it worked well .
And the switch item configuration Switch Sprinklers_Switch "Sprinklers switch" (Switches){channel="mqtt:topic:baba:terrace_sprinklers:Sprinklers_switch"}
I’m not a very experienced openhab user but I think the problem is that you defined the button as a switch. I think that switch type can only be ON/ OFF. Try to change Switch to Dimmer.
And here is the log
23:03:02.426 [INFO ] [smarthome.event.ItemCommandEvent ] - Item ‘Kitchen_VentilationtMode’ received command 100
23:03:02.441 [INFO ] [smarthome.event.ItemStateChangedEvent] - Kitchen_VentilationtMode changed from 0 to 100
