FreeMaint Connect
Connect meters and sensors: live measurements, alerts that open work orders, and meter-based maintenance
FreeMaint Connect: connected devices and sensors
What FreeMaint Connect does, which devices it supports, what the Business plan includes and how measurements turn into maintenance.
Connect a Shelly energy meter
Pair a Shelly Pro 3EM, EM Gen3, Pro EM-50, Plug S Gen3 or 1PM Gen3 with FreeMaint by pasting one script — no gateway needed.
Connect LoRaWAN sensors
Send LoRaWAN uplinks to FreeMaint from The Things Stack, ChirpStack or a Milesight gateway, and let FreeMaint decode the certified sensors.
Send measurements with the HTTP API
Send JSON from Node-RED, Home Assistant, a PLC gateway or your own script to FreeMaint Connect: format, headers, units and limits.
Alert rules: from a measurement to a work order
Watch a channel with a threshold, rate-of-change, vibration-zone or no-data rule; be notified and open a work order automatically.
Channels, asset meters and run hours
Calibrate channels, link them to an asset meter for meter-based preventive maintenance or to an energy meter, and count run hours.
