How to swap a Crunchtime Temp Monitoring sensor in the Ops Execution app

Crunchtime Temp Monitoring uses sensors to collect temperature readings for cold storage locations like reach-in coolers and walk-in freezers.

If a sensor stops working and you get a replacement sensor, you can swap out the old sensor for the new one directly in the Ops Execution mobile app. By swapping a sensor, it will keep the history from the previous sensor so you get a full view of temperature history for exporting and reporting. Swapping a sensor, instead of removing and re-installing, also gives you a more accurate offline-sensor percentage.

This article provides instructions on how to swap a sensor. Visit our other articles for troubleshooting tips and installation steps for temp monitoring gateways and sensors.

How to swap a sensor in the mobile app

All users, submitters, managers, and admins, can swap sensors in the Ops Execution mobile app.

1. Open the Ops Execution mobile app
2. Open the Sensors menu
3. Tap on the sensor that you want to swap
4. Tap Swap sensor
5. On the back of the new sensor, locate the QR code and DevEUI
6. In the app, tap Scan QR Code or Enter manually
7. Follow the instructions in the app to add the code from the device label and then tap Swap
8. You will see a “Success!” message once the new sensor is added

Why does the new sensor appear offline?

The new sensor will appear offline until Ops Execution gets a temperature reading from it. It can take up to 15 minutes for data from the new sensor to load.

How can I see when a sensor was swapped?

There are three ways that you can see if a sensor was swapped in the Sensors menu.

• Sensors will have a Recently Swapped icon next to them.
• In the Sensor Details menu, the temperature graph will have a dotted vertical line to show when a swap happened.
• In the Ops Execution web app, there is a swap log in the Sensor Details menu that shows the date, time, and manufacturer.
