Real-time alerts

Access to real-time alerts empowers fleet operators to quickly respond and replace the lamp, if necessary, while still on the road. The knowledge of a lamp being out gives them the option to replace it on the road or risk the CSA violation and continue on their route.

Up to 100 times per second

The smart system measures both voltage and current to determine when a change in current has occurred that is the result of a lamp going out. — It samples at a rate of up to 100 times per second.

Once the Grote Guardian Smart System has detected an outage, it then sends fault information through three different methods depending on your preference: to telematics devices, via Bluetooth to our mobile app, available on iOS and Android, or through the use of a geo-fence gateway.

With Grote Guardian's Geofence capabilities, you get data on lighting problems as soon as your trailer enters the yard. The geofence is set up at the fleet location using an easy-to-set-up gateway, creating a virtual boundary that automatically uploads information from Guardian whenever a trailer with the Grote Guardian Smart System enters the lot. Our cloud-based software will automatically generate an email with any fault conditions to be sent to the maintenance manager for the hub.
