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

Inputs

Channels: 6 total — 4 analog probe inputs + 2 dry-contact inputs
Analog inputs: 4 channels for FreshControls 10 k NTC probes, 16-bit conversion

Probe range: −50 °C to +150 °C with FreshControls NTC probes
Probe accuracy: ±0.5 °C typical

Connectivity & reporting

Backhaul: Wi-Fi or long-range LoRa — both radios are fitted, and one is chosen per board during setup
Wi-Fi: Wi-Fi 802.11 b/g/n, 2.4 GHz, WPA2 / WPA3-Personal — joins your existing network, no gateway required
Long-range: LoRa, sub-GHz ISM (US915 / AU915). Requires a FreshControls gateway (FC-GW-E or FC-GW-C) already installed at the site
Setup: Set up over Bluetooth within Wi-Fi range — a long-range board collects its gateway pairing over Wi-Fi once, then it is mounted where it belongs

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 where coverage reaches.

Long-range path

Gateway-backed LoRa

LoRa deployments use a gateway with Wi-Fi uplink and up to 32 children. Confirm range and availability for your site. Pure LoRa child firmware updates are not currently supported.

Nothing goes quiet unnoticed

Server-side alarm evaluation

Alarms are evaluated on the platform, so a device that stops reporting raises an offline alarm after its configured timeout instead of leaving a silent gap. Monitoring data and login credentials are stored in your chosen region; notification providers process delivery content.
