Birds off feed for a few hours set the whole house back
When a bin empties overnight, the feed lines run dry and every bird in the house goes without until someone notices in the morning.
A low-level alert on the phone turns that into a delivery call made in daylight, with feed still in the bin.
Knocking on a bin is a guess, and climbing one is a risk
Feed bridges and cones hang up, so the sound on the outside of the bin or a look through the hatch often says more feed is left than there is.
A radar on the roof measures the distance to the feed surface from above, on every reading, without anyone going up a ladder.
A farm with several houses needs one picture of its feed
Seeing every bin side by side is what lets the farm order one full truck instead of topping up whichever bin someone checked last.
The same screen shows the air quality and fan status of each house, so feed is not a separate system to open.
