Dual-Alert Monitoring Kit

This Emerson WiPOPFIRSTFi kit includes two wireless sensors and a central receiver designed for refrigerator and freezer temperature tracking. It serves homeowners who want immediate local notification alongside smartphone alerts when temperatures drift outside safe limits. The system operates on a 2.4G WiFi connection only.

Upgrade From Silent Phone-Only Sensors

Unlike basic WiFi probes that rely solely on push notifications, this kit adds a dedicated indoor receiver with a 90dB adjustable alarm. The jump is worth it when you need an audible warning that wakes you or reaches another room without depending on a phone speaker or internet connectivity. The gateway reconnects automatically after a power or internet outage lasting more than 30 minutes.

Two Sensors Expandable To Five

The package supports simultaneous monitoring of a fridge and deep freezer, with capacity to add up to three additional transmitters for wine cellars or garage units. Each sensor uses a 1.45mm ultra-thin probe wire that slips through door seals without breaking the vacuum. Wireless range reaches 328ft through walls, covering most residential layouts.

Questions about this item

Will the 1.45mm flat probe wire fit through my refrigerator door seal without breaking the vacuum?

The 1.45mm ultra-thin probe is engineered to pass through standard refrigerator door seals without breaking the vacuum or causing energy loss.

Which Wi-Fi band must my router use for the gateway to connect during setup?

The gateway requires a 2.4GHz Wi-Fi network; 5GHz is not supported. Ensure the gateway is within 330 feet of the router in open areas.

What battery replacement should I plan for since the sensors are battery powered?

The sensors and receiver are battery powered; plan to replace batteries periodically to maintain the 328ft wireless range and 90dB alarm function.
