Motive Door and Environmental Sensor (DES-2) enables accurate monitoring of door activity and environmental conditions, ensuring security and operational efficiency.
Overview
Door & Environmental Sensors give fleets real-time visibility into refrigerated assets by combining door, temperature, and humidity monitoring in a single device. Fleet Managers and Fleet Admins can see exactly when reefer doors open and close, monitor conditions inside every zone, all from the Motive Fleet Dashboard.
- Monitor Reefer: Use continuous temperature and humidity monitoring to keep reefers within a defined range.
- Track door activity: The Door and Environmental Sensors help detect both swing and roll-up doors in real time.
- Configure Alerts: Create real-time email and SMS alerts when doors are left open too long, or reefer temperatures move outside the set thresholds.
- Review Reports: Use Reefer Activity and Door Sensor Events reports to get a historical view of the door status, temperature & humidity data for a specific reefer.

Supported Devices
Devices that Support Door & Environmental Sensors
- Asset Gateway (AG 31.3)
- Vehicle Gateway
| Note: When Vehicle Gateway is selected as a source, trip history will not be available. |
Installation: Door and Environmental Sensor
1. Press and release the pinhole button on the side of the sensor by inserting the pin.
2. The LED will blink blue, indicating the sensor is beginning the pairing process.
3. Proceed immediately to the positioning instructions for the door type.
| Note: This blinking behavior is for the first 30 minutes after activation or button press. |
Positioning on a Roll-up Door
- Set aside the magnet provided; it is intended for Swing Doors, not Roll-up Doors.
- Orient the sensor with the LED on the bottom, as shown. Place the sensor on the door in such a position that it will be vertical (perpendicular to the floor) when the door is closed and horizontal (parallel to the floor) when the door is opened. If possible, attach the sensor to the interior side of the door.
- Proceed to the mounting instructions.
Positioning on a Swing Door
- For installing on Swing doors, place the magnet on the top edge of the door.
- Place the sensor on the ceiling, oriented so the LED is directly facing the magnet.
- Ensure the sensor and magnet are within the following maximum distances:
- Metal surfaces: 12mm (½ inch apart)
- Other materials: 22mm (⅞ inch apart)
- When the door closes, the sensor blinks green once. When the door opens, it blinks white once.
| Note: This blinking behavior is for the 1st 30 minutes after activation or button press. |
| Note: If the sensor will not fit on the ceiling, you can swap the positions of the sensor and magnet as long as the sensor's LED continues to face the magnet and within maximum distance of the magnet. Proceed to the mounting instructions. |
| Note: The Door & Environmental Sensor can be installed on both a roll-up or swing door on a refrigerated truck. |
Mounting
- Use the included alcohol wipe to clean the area where you want to attach the mounting plate and magnet.
- Remove the adhesive backing from the mounting plate and affix it to your desired location.
- If using the magnet, remove its adhesive backing and affix it to your desired location.
- For metal surfaces, use the small mounting plate screws; for wood surfaces, use the large mounting plate screws.
- Attach the sensor (and magnet, if used) to the mount and secure it using the device screws.
- At least 10 minutes after you first push the pinhole button, quickly press and release the button again.The LED will turn solid blue if your sensor has successfully paired with your Asset Gateway.
| Note: If your Motive Gateway is installing firmware updates, you may need to wait 30-60 minutes before your sensor is successfully paired and data appears in your Fleet App or dashboard. |
Assigning a Door and Environmental Sensor to an Asset using the Fleet App
- After installing the Door and Environmental Sensor, download the Motive Fleet App from Google Play Store or Apple App Store and log in as an admin or installer.
- Log in to the Motive Fleet App and go to More > Devices.
- Tap Install Door and Env. Sensors.
- Select the Door & Environmental Sensor you want to assign from the given list or use the search bar to find the sensor by entering its serial number.
- Tap Continue.
- Select an asset from the given list or use the search bar to find the asset.
- Select the data transmission source between the Asset Gateway or Vehicle Gateway.
- Select a Sensor Usage option.
- Select your Door type from the given options.
- Select the temprature Zone for the installation of your Door and Environmental Sensor.
- Select one of the given Location options for the installation.
- Tap Assign.
- Confirmation pop-up changes to Assigning… state while the sensor is being assigned.
- Place the Door and Enviornmental Sensor at the mounting location and tap Next.
- Follow the given instructions to activate the sensor.
- Tap Light flashed blue once the sensor is activated and flashing blue.
| Note: Do not press and hold the pinhole button. Instead, quickly press and release it to begin pairing with the Asset Gateway. The LED will start blinking blue if done correctly. If the light does not flash blue, tap Light did not flash blue and follow the given steps for troubleshooting. |
- Sensor data will start refreshing.
- Once refreshed, you can see the Door status, Temprature and Humidity of the selected Zone.
- Tap Refresh data if you want to refresh the values again.
- Tap Continue to proceed.
- From Assignment complete screen, you can go to the Installation guide for next steps, tap Install another sensor or tap Finish to proceed as you wish.
- Once the Door and Environmental Sensor is paired with Asset Gateway, its door status, temperature and humidity will appear on your Fleet Dashboard.
Assign a Door and Environmental Sensor to an Asset in the Fleet Dashboard
| Note: Before installing a Door & Environmental Sensor, the Vehicle Gateway or Asset Gateway needs to be attached to a Vehicle Asset. |
- Log in to the Motive Fleet Dashboard and click the Admin icon.
- Go to Assets, click the three dots next to the desired asset and select Edit Asset.
- Go to Sensors > Data Transmission Source > + Select source and select either Asset Gateway or Vehicle Gateway. The selected device will transmit data for all sensors assigned to the asset.
- Assign a Vehicle Gateway or Asset Gateway.
| Note: When Vehicle Gateway is selected as a source, trip history will not be available. |
| Note: Before installing a Door & Environmental Sensor, the Vehicle Gateway or Asset Gateway needs to be attached to a Vehicle Asset. |
- Click + Assign sensor.
- Select a Door & Environmental Sensor and click Assign.
- Select an installation zone, location and click Assign.
- Once a Data Transmission Source and Door & Environmental Sensor are assigned, click Save.
Replacing the battery of a Door & Environmental Sensor
Door & Environmental Sensors come with non-rechargeable CR2477X batteries that allow for better performance in low-temperature situations and have been tested to last up to 3 years under normal usage. Hence, whenever your Door & Environmental Sensor’s LED is solid red, you will need to replace the battery with another CR2477X battery.
- Flip the device over and using a T6 screwdriver, remove the screws.
- Gently remove the battery from the battery holder and replace it with a new battery.
| Note: Please purchase a Murata CR2477X battery when replacing the battery to ensure optimal performance at low temperatures. |
- Ensure that the waterproofing rubber seal is placed well in the top housing groove.
Place the lid on the back and screw it tightly.
LED light indicators
The color of the LED light on the Door & Environmental Sensor has different meanings. Refer to the following table to understand the meaning of the LED colors and patterns:
| LED Color | Meaning |
| Solid blue (5 seconds) | Working properly. It is paired and has a good signal. |
| Blinking blue (10 seconds) | Trying to pair with a Vehicle Gateway or Asset Gateway. |
| Blinking red (10 seconds) | Paired Vehicle Gateway or Asset Gateway can not be found. This can happen when the Vehicle Gateway or Asset Gateway mini is on battery power. |
| Solid yellow (5 seconds) | Connectivity to the Vehicle Gateway or Asset Gateway is weak. The sensor is still paired but has a poor signal. |
| One blinking blue | After a pinhole press, this means it’s sending a breadcrumb. |
| On blinking green | Sensor detected a transition from Door Open to Door Closed. |
| One blinking white | Sensor detected a transition from Door Closed to Door Open. |
| One blinking red | A 5-second press of the pinhole button will return the device to its out-of-the-box state. |
