Freezer plan software on up to 5 sensors for 60 days. Use compatible sensors you already own or rent ours for the trial period.
Are sensors included in the per-sensor price?
No. The plan price is for software, alerts and records. Sensors and gateways are bought once or rented monthly, and rental includes calibration and swap-outs.
What counts as a sensor?
Each probe reporting a reading. A cold room with probes at the door and the back counts as two.
