Outdoor temperature logger

The YoLink YS8014 X3 sensor monitors outdoor or submerged temperatures with a waterproof probe and logs data locally when the hub is unreachable. It runs on two user-replaceable AA lithium cells rated for more than five years of operation. A YoLink hub is mandatory for network connectivity and alerting.

Upgrade from battery-limited sensors

Replaces earlier probes that last only two years on AAA cells and cannot store readings offline. The jump is worthwhile when you need multi-year deployments without battery swaps and when gaps in connectivity must not create gaps in the temperature record.

Handles pool, freezer and compost duty

Comfortably tracks water, refrigeration and compost temperatures across a 158 °F span with ±0.3 °F accuracy. Offline logging capacity is finite; very long disconnections will eventually overwrite the oldest samples. The probe cable length and hub range set the practical placement limits.

Questions about this item

How wide is the sensor body for mounting clearance?

The sensor body measures 2.97 inches wide, so allow at least that much flat space on the wall or magnet surface.

What step do people miss when pairing the sensor with the hub?

Press the SET button on the sensor after adding it in the YoLink app; without that press the hub will not recognise the device.

When do the two AA lithium cells need changing?

The manufacturer rates the battery life at 5 years; replace both cells together when the app reports low voltage.
