Consumables
Equipment that consumes something (reagent, dosing liquid, top-off water, filter media) can tell Cora how much is left. Cora can warn you before it runs out.
Setting a refill alert
Open the device (from the Devices tab, or by tapping its tile on the dashboard), then use the bell in the top bar.
Equipment with more than one container gets one threshold per container, so a head you watch closely and a head you rarely touch can be set differently.
Most thresholds are set in days, not volume. Cora works out how long what is left will last at the rate you are actually using it, which is the number you can act on; "four days of calcium left" tells you something that "180 mL left" does not.
| Device | Threshold on |
|---|---|
| Trident | Tests remaining, and how full the waste bottle is |
| Dosing head | Days of supplement left; some also offer millilitres remaining |
| ATO | Days of reservoir left |
| Mat roller | Days of roll left |
A consumable alert behaves like any other alert: it appears in the Alert Center and can push to your phone. You get one notification when a level is passed, not a repeating stream, and it clears when the level returns above the threshold.
Choosing a threshold
Set it far enough ahead that you can act. A threshold that fires the day something runs out gives no warning.
After refilling
Reset or update the level on the device's page so the alert clears and the next warning is calculated correctly.
