Hi, I need create something that user can set time of the day in basic UI then I can send this time data to MQTT broker or trigger an event via rule. Openhab seem doesn’t have an item to do that. Can you help me.
No because as you said, openHAB does not have an input item (widget) for that, at least none that works out of the box. So use number or string inputs and process them either in UI or rules.
This might help?
