## How to Program Alert Limits in the SimpliSafe App The mobile app is the primary tool for setting specific high and low temperature thresholds. Follow these steps to program your limits: 1. **Open the SimpliSafe App**: Launch the app on your smartphone or tablet and log in to your account. 2. **Navigate to Device Settings**: Tap the **My System** icon at the bottom of the screen. If you do not see it, tap the three horizontal lines (menu icon) in the top-left corner and select **Device Settings**. 3. **Select Your Sensor**: Scroll through the list of installed devices and tap on your **Temperature Sensor**. If you have renamed the sensor (e.g., "Basement" or "Utility Room"), look for that custom name. 4. **Enable Custom Alerts**: Locate the toggles for **High Temp Alert** and **Low Temp Alert**. Slide the toggles to the "On" position to enable customization. 5. **Adjust the Thresholds**: Use the sliders or input fields to set your desired temperature limits. For example, you might set a high limit of 85°F for a server closet or a low limit of 55°F for a basement. 6. **Save Your Settings**: Tap **Save** in the top-right corner of the screen. The app will sync the new limits to your Base Station. ## How to Configure Settings Using the Keypad

While the SimpliSafe Keypad allows you to add, name, and remove sensors, it does not support the detailed programming of custom high and low temperature alert limits. You must use the mobile app to set specific temperature thresholds. However, you can use the Keypad to verify that the sensor is online and properly named: 1. Press the **Menu** button on your Keypad. 2. Enter your **Master PIN**. 3. Select **Devices**. 4. Scroll to and select your **Temperature Sensor** to view its current status and serial number. ## Understanding the Default 41°F Freeze Alarm

It is important to understand the difference between the sensor's default freeze alarm and your custom programmed alerts: * **The Default 41°F Trigger**: Every SimpliSafe Temperature Sensor is pre-programmed to trigger a critical freeze alarm if the temperature drops below 41°F (5°C). This limit is hardcoded to protect your home's plumbing and cannot be changed or disabled. If the temperature drops below this point, the Base Station will sound, and the monitoring center will be notified. * **Custom App Alerts**: The high and low limits you program in the app do not trigger a full security alarm or dispatch emergency services. Instead, they send a push notification directly to your phone to warn you that the temperature has drifted outside your preferred range. ## Where to Place Your Sensor for Accurate Readings To prevent false alerts and ensure your programmed limits function correctly, place the sensor in an optimal location:

* **Avoid Direct Drafts**: Do not place the sensor near vents, radiators, air conditioners, drafty windows, or exterior doors. * **Target Vulnerable Areas**: For pipe protection, place the sensor in crawl spaces, basements, or under sinks where pipes are most likely to freeze. * **Mounting**: Use the included adhesive strip to mount the bracket to a clean, dry wall, then slide the sensor into place. Keep it off the floor to avoid water damage in case of minor leaks. ## Troubleshooting Sensor Sync Issues If your new temperature limits do not seem to save or you are not receiving alerts, try these troubleshooting steps: * **Wake the Sensor**: Battery-powered sensors enter a sleep state to conserve power. After saving your settings in the app, press the test button on the top or side of the physical Temperature Sensor to force it to communicate immediately with the Base Station. * **Check the Distance**: Ensure the sensor is within range of the Base Station (up to 800 feet in an open field, though walls and household wireless interference will reduce this range). * **Replace the Battery**: If the sensor is unresponsive, slide it off its bracket and replace the CR2032 lithium battery.
