If you are setting up multiple sensors, it is best to pair them one at a time to avoid confusion when naming each location in your system. ## Step-by-Step Setup and Pairing You can add the temperature sensor to your security system using either your physical Keypad or the SimpliSafe mobile app. ### Method 1: Using the SimpliSafe Keypad

1. Press the **Menu** button on your Keypad and enter your Master PIN. 2. Navigate to **Devices** and select **Add Device**. 3. Scroll through the device list and select **Temp Sensor**. 4. Locate the temperature sensor and pull the paper battery tab out from the bottom. 5. If the battery tab has already been removed, press the small **Test Button** on the top or side of the sensor to put it into pairing mode. 6. The Keypad will beep and confirm that the sensor has been successfully added. 7. Choose a pre-set name for the sensor (such as "Basement" or "Utility Room") or create a custom name to easily identify its location. ### Method 2: Using the SimpliSafe App 1. Open the SimpliSafe app on your mobile device. 2. Tap the menu icon (three horizontal lines) in the top corner and select **My System**. 3. Tap **Device Settings** and then select **Add Device**. 4. Select **Temperature Sensor** from the list of available devices. 5. Pull the battery tab from the sensor, or press the physical pairing button on the sensor body. 6. Once the app detects the sensor, follow the on-screen prompts to name the device and save your settings. ## Choosing the Best Location for the Sensor

Proper placement ensures that the sensor provides accurate readings and avoids false alarms. ### Recommended Locations * **Near Plumbing Pipes:** Place the sensor in crawl spaces, basements, or under sinks where pipes are susceptible to freezing during winter storms. * **Utility Rooms:** Mount the sensor near your water heater or main water shutoff valve. * **Unheated Areas:** Attics, garages, or greenhouses are ideal spots if you need to monitor temperature fluctuations. ### Locations to Avoid

* **Directly on Metal:** Avoid mounting the sensor directly onto metal pipes or metal beams, as metal can block the wireless signal to the Base Station. * **Near Heat Sources:** Do not place the sensor directly next to air vents, radiators, space heaters, or appliances that generate heat. * **Drafty Areas:** Keep the sensor away from poorly sealed windows or exterior doors where drafts could cause inaccurate low-temperature readings. * **The Floor:** Mount the sensor on a wall rather than placing it on the floor. If a pipe bursts, standing water could damage the sensor's internal electronics. ## How to Mount the Sensor The SimpliSafe Temperature Sensor comes with pre-applied adhesive tape for quick installation. 1. Clean the wall or surface where you plan to place the sensor using rubbing alcohol, then let it dry completely. 2. Slide the sensor off its mounting bracket. 3. Peel the protective paper backing off the adhesive strip on the bracket. 4. Press the bracket firmly against the wall for 30 seconds to ensure a strong bond. 5. Slide the sensor back down onto the bracket until it clicks into place.

If you prefer a more permanent installation, you can screw the bracket into the wall. Slide the sensor off the bracket, insert screws through the provided holes in the plastic backing, secure them to the wall, and slide the sensor back on. ## Configuring Temperature Thresholds By default, the SimpliSafe Temperature Sensor triggers a freeze warning if the temperature drops below 41°F (5°C). If you have an interactive monitoring plan, you can customize these thresholds through the SimpliSafe app. 1. Open the SimpliSafe app and go to **Device Settings**. 2. Select your **Temperature Sensor**. 3. Adjust the low-temperature and high-temperature thresholds to fit your specific needs. 4. Save your changes.

If the temperature crosses these limits, the Base Station will sound an audible warning, and you will receive a push notification or SMS alert on your phone. ## Troubleshooting Common Issues If your sensor is not working correctly, try these troubleshooting steps: * **Sensor Not Found During Setup:** Ensure the sensor is within close range of the Base Station during the initial pairing process. If it still does not pair, remove the battery for 10 seconds, reinsert it, and try pressing the pairing button again. * **Sensor Offline Alert:** If the sensor frequently goes offline after installation, it may be too far from the Base Station or obstructed by thick walls. Try moving the sensor to a slightly different position or closer to the Base Station. * **Low Battery:** The sensor uses a standard CR2032 lithium battery. If you receive a low battery notification, slide the sensor off its bracket, open the back cover, and replace the battery.
