Products
Controllers and sensors designed and developed in Israel, built to run for years inside fridges, freezers and cold rooms. Every component connects to one system, with a private dashboard and real-time alerts.
GNS24GW
8-channel controller and RF hub
A controller that accepts up to 8 wired sensors of different types. As GNS24GW it also acts as a gateway: a hub for RF sensors deployed across the site, up to 300 m away. Built for customers with large premises.

GNSble1
Wireless Bluetooth sensor
A Bluetooth sensor with a built-in probe, powered by a strong battery that lasts up to 8 years. Place it inside the cooling unit and you’re done.
GNSble2
Bluetooth sensor with an external probe
A Bluetooth sensor with a 1 m external probe. The sensor body stays outside the cold area while the probe goes inside, keeping a strong signal to the BLE32 controller.
LoRa
Long-range RF sensor
A sensor that talks to the GNS24GW controller over radio frequency (RF) for long-range reception. We deploy these where sensors must be spread over a very large area.
Local sensor
Wired temperature sensor
A local sensor that connects directly to the controller. Up to 8 can be chained in series.
Humidity, acidity (pH), CO₂ and more, to your requirements. Our controllers can translate data from any kind of sensor.
