Help simple structure

[bobo3366]

Hi
Sorry, maybe the question will seem stupid but I don't understand what I have to do ....
I list what I did:

1. installed OpenHab on Raspberry (configured working)
2. I connected a motion sensor (ESP8866, OK)
3. I defined the MQTT channel (I receive regulation 0/1)
4. I have attached to the Dashboard the sensor (pin) that identifies me if on or off.

I wanted :

• Historicize alarms (possible on DB to keep data)
• create a graph with any alarms over time.

Who can help me (maybe by sending a sample)

Thank you
