A multi-shed poultry farm where problems were being discovered at the morning round instead of when they happened.
The problem
Each shed had its own controller, and each controller was only visible to someone standing in front of it. A fan stopping overnight, or a generator failing to pick up, was only noticed on the next round.
What we did
The result
The owner can open one screen and see every shed's temperature and ventilation state, and gets an alert when a shed goes out of band or the power fails. Overnight history is available the next morning, so patterns can be seen instead of remembered.
We'll survey the farm and propose what to monitor first — usually temperature, ventilation and power.
