The sensor that lives inside the cold.
An ultra low-power transmitter reading temperature, humidity, door state, vibration and electrical consumption — and surviving years on its own battery.
Installed in minutes
Magnetic or adhesive mounting, QR code pairing and setup in the app. No electrician, no downtime.
Its own network, independent from store Wi-Fi
Sensors talk to the receiver over ESP-NOW, peer to peer by MAC address. No SSID, no password, no going down with the internet.
It's also a smart switch
In the relay version, the same module meters the outlet and powers the equipment on or off remotely, gated by permissions.
Never loses a reading
The receiver writes everything to an SD card with a real-time clock. If the internet drops, the series comes back complete on reconnect.
What it sees
One compact device, many readings. That is how the cost drops without losing capability.
