- Worth noticing
- The page says silent probes are marked stale or offline, so a last-known value does not pose as a current reading.
Field notes
The homepage separates habitat-specific measures rather than applying aquarium metrics to every setup: its examples include basking and cool-zone temperatures for terrariums, and dissolved oxygen and turbidity for ponds. For sensor data, it describes a latest reading alongside a six-hour average and range, and says offline or stale probes are labeled instead of presenting old values as current.
