Protection for your existing equipment
A separate view.
A clearer response.
Morphy adds independent monitoring to the refrigeration you already own. A separate reading, and a team ready to act.
01 / Separate
Separate by design.
Monitoring that reads through the refrigeration controller sees what the controller reports. Morphy measures for itself.
Morphy is an independent witness. Its sensors attach to the equipment and report outbound through Morphy’s own cellular gateway to Morphy’s cloud. Nothing connects to the refrigeration controller or the store’s IT network.
The monitoring installation has no control connection: it cannot change setpoints, start defrost, or switch the equipment off.
02 / See
Independent eyes.
A compromised controller may show a misleading temperature—or stop showing one at all.1 Morphy measures temperature and compressor current separately.
Most monitoring is set to look past defrost. Morphy watches it, and a warm-up with the door closed raises one of two alerts. If the compressor has stopped, with zero amps while the temperature rises, it’s an equipment emergency. If the compressor is drawing normal current and the box still warms, it’s possible controller tampering, for a person to check. We also compare Morphy’s reading with one checked at the controller.

Sample dataThis sample is possible controller tampering: the box warms with the door closed while the compressor draws normal current. If the compressor had stopped, with zero amps while the temperature rose, it would be an equipment emergency instead.
Illustrative controller trace only; Morphy does not connect to the controller. In the app, a store or technician enters a timestamped display reading. Defrost is inferred from Morphy’s own sensors, not read from the controller.
03 / Respond
From alert to technician.
Possible tampering is an emergency, so it goes straight to your facilities manager. They dispatch through ServiceChannel to the vendor that covers the store: in Tennessee, that’s Ozmon & Company. The technician sees the unit’s history, and what was found and fixed stays with the event.
-
Alert
Your facilities manager gets the unit and its readings at once.
-
Facilities manager checks
Call the store. Check the controller display, the door, and any authorized changes.
-
Dispatched through ServiceChannel
To the vendor that covers the store. In Tennessee, that’s Ozmon & Company.
-
Fixed & documented
The technician checks the equipment, works with the network owner to remove exposure, restores approved settings, and verifies cooling. The record stays with the event.
04 / Be clear
What Morphy is not.
Morphy does not prevent someone from reaching an exposed controller. It adds a separate way to notice trouble and begin a response.
It is designed for prompt visibility while sensors, power, and cellular service are available. It is not a guarantee of detection time or a substitute for securing the controller.
- Keep controllers off the open internet.1
- Update supported devices; retire unsupported ones.1234
- Change default passwords and secure access.1
- Remove unnecessary remote access; protect any that remains.1
