  • Service Contract

    • 1 Year warranty against any manufacturing defects.
    • Client responsible for getting devices to our facilities for all servicing. Service time 7-10 working days.
    • Warranty is void if the device is opened, tampered with or electronics damaged due to mechanical shock.
    • Warranty does not include sensor change.


Note: Note: After making changes to the app, the device must be turned off and on once, and connected to the internet to receive updated settings from the server.
  • Measurement Frequency
    • Default
      • Cloud Storage: Data is measured every 30 seconds (measurement frequency ) and sent to the server every 1 minute (Sending Frequency).
    • Configurable Measurement frequency
      • Can be changed to 1min, 5min, 10min, and 20min via mobile app.
      • Note:
        • Longer sending frequency reduces power usage and battery backup as sending data to the server is very battery intensive.
        • Longer measurement frequency ensures longer local memory as a fixed number of items are stored in the memory. Also the sensor is turned off in between intervals which may help extend sensor life.
  • Alert Limits and Traffic Light Signal
    • Alert limits can be configured for each parameter via the app.
    • Get notifications on the app when alert limits are exceeded
  • Communication
    • Wi-Fi
