Using moisture sensors to control programs

[cdesouza]

Hi,

I have some Zigbee moisture sensors that I connect to my MQTT server using Zigbee2MQTT.

I would like to try and write a plugin that

• Assigns a sensor to a station (via an MQTT topic?)
  
• Allows the setting of a threshold moisture value per station
  
• Suppresses any program from running for a station if the reported moisture value is higher than the threshold value
  
• Shows if a program has been suppressed
  
• Shows a graph of the moisture sensor values
  

Can someone please give me any pointers as to how to best to go about writing such a plugin?

Thanks in advance.
