Read sensor history
STICKER can store measurements on the device (store-and-forward), so readings taken while it was offline are not lost. Read those stored records back over NFC.
- Open HARDWARIO Manager and go to STICKER → Tools → Sensor history.
- Hold the phone against the STICKER and keep still.
- The stored records are read in and shown 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.
What you get
The screen is a data view, not a raw dump:
- a summary of what was read,
- charts of the stored values,
- per-day tables you can expand for the individual records.
Timestamps depend on the device clock. If the device's time has been synchronised, records carry absolute UTC timestamps; if it has not, they are shown relative to the read instead. Use Tools → Sync time to set the clock — see Tools.
History has to be enabled first
Records are only kept when history is turned on. Enable it and choose which
channels to store under Configuration → History — see
Configuration — or over the shell with
config history-enable / config history-sensors, described in
Sensor History (Developer Access).
Reading sensor history over NFC requires STICKER firmware v1.4.0 or newer.
To take a fresh reading instead of reading stored data, use Sample sensor data.
