## What is SI?

SI Field is the official mobile app for Sensor Industries customers and field technicians, putting real-time sensor management in the palm of your hand.


WORK ORDERS — FOR PROPERTY STAFF

Stay on top of every open maintenance request at your property. View work order details, add timestamped notes, select completed action and cause, and close out jobs — all from your phone, without logging into a desktop dashboard.


SENSOR INSTALLATIONS — FOR TECHNICIANS

Sensor Industries technicians and contracted installers can follow a guided, step-by-step installation workflow:

- Browse properties and select the target unit and slot
- Scan or enter a device serial number for instant validation
- Create the sensor assignment directly from the field
- Run a live device health check to confirm the sensor is communicating
- Capture and upload install photos
- Review the completed assignment before leaving the site


OFFLINE-FIRST SYNC

No signal? No problem. Completed installs are saved locally and automatically synced when connectivity is restored.


SI Field requires a valid Sensor Industries account. Contact Sensor Industries to get access.
