Read sensor history

STICKER can store measurements on the device (store-and-forward), so readings taken while it was offline aren't lost. Read those stored records back over NFC.

  1. Open Hardwario Manager and go to Sticker → Tools → Sensor history.
  2. Hold the phone against the STICKER and keep still.
  3. The stored records are read into a table for review.

Because an NFC tap exchanges one page at a time, a large buffer is read in pages — keep tapping to pull the next page until everything is loaded.

History must be enabled first

Records are only kept when history is turned on. Enable it and pick which channels to store under Configuration → History (see the Configuration guide), or over the shell with config history-enable / config history-sensors — see Sensor History (Developer Access).

To take a fresh reading instead of reading stored data, use Sample sensor data.
