FC-MI-4-L

4-Input Monitoring Board (Wi-Fi + Long-Range)

Multi-input boardWi-Fi or LoRa

The FC-MI-4 with a long-range radio added: the same four probe inputs and two dry-contact inputs, and two ways to connect. Your installer picks one during setup — your Wi-Fi, with no gateway at all, or a FreshControls gateway for the coolers Wi-Fi never reaches.

  • One board, two ways to connect — chosen during setup, changeable later
  • On Wi-Fi it needs no gateway at all; on long-range it joins a FreshControls gateway already installed at the site
  • Same 4 probe inputs and 2 dry-contact inputs as the FC-MI-4

How it fits together

Mix and match to cover any site.

Sensors within reach of an access point join over Wi-Fi on their own. For sprawling warehouses, freezers, and outbuildings, long-range sensors report through a gateway. Existing probes and door contacts fold in through the monitoring board — all onto one fleet.

Wi-Fi path

Straight onto your network

FC-TRH-W sensors and the FC-MI-8 board report over your existing Wi-Fi or a wired drop — no extra infrastructure where coverage already reaches.

Long-range path

Gateway-backed LoRa

FC-TRH-L sensors reach an FC-GW-E or FC-GW-C gateway over sub-GHz LoRa, covering the deep-freeze and far-corner spots Wi-Fi never makes.

Nothing goes quiet unnoticed

Server-side alarm evaluation

Alarms are evaluated on the platform, so a device that stops reporting raises an offline alarm instead of leaving a silent gap. Operational data and credentials never leave your region.
