If a gateway outage or a weak signal causes gaps in Conserv Cloud, you can recover those readings in two ways: - **Automatically**: The sensor resends recent readings after a short outage. For more information, see Fill Data Gaps Automatically. - **Manually**: You connect to the sensor with the Conserv Cloud Mobile App, and the app uploads the stored readings to Conserv Cloud. For more information, see [Fill Data Gaps Manually](https://claude.ai/epitaxy/local_ce618de8-190c-4f75-8756-bc1c69971aac#fill-data-gaps-manually). Conserv Cloud uses the time information saved with each reading to place the reading on your timeline. It will not add readings that already exist, so you can safely repeat the upload if needed. **Important** Data infill **only** works on SCS-3 sensors (**serial numbers c006000 or above**) with firmware 1.6.0 or later. For more information, see [Sensor and Firmware Requirements](https://claude.ai/epitaxy/local_ce618de8-190c-4f75-8756-bc1c69971aac#sensor-and-firmware-requirements). The sensor must also be on and cannot record data if the batteries have been removed or the sensor is de-activated. If you do replace the batteries at a given time, it will be important for the sensor to connect to the gateway at least once before it can start recording retrievable data again. ### Protect Your Data Before a Reset The sensor gets the current time from the gateway, and uses it to timestamp each reading. The type of reset you use determines whether the sensor has the current time after the reset. | Action | Effect on stored readings | | --- | --- | | Smart reset in the Conserv Cloud Mobile App (firmware 1.14.0 or later) **OR** reset that occurs automatically after a firmware update. | The sensor saves the current time from your phone before it resets. You can recover readings from before and after the reset. | | Hard reset with the reset button on the back of the sensor | The sensor may not have the current time until it connects to a gateway again. Some readings may be difficult to retrieve. | | Hard reset by removing or replacing the batteries | The sensor does not have the current time until it connects to the gateway again. | **Caution**: If you need to reset a sensor, use a smart reset. Use a hard reset only when the Support Team recommends it. Before a hard reset or a firmware update, fill any gaps in your data. For more information about the types of reset, see [Reset a Sensor](https://support.conserv.io/knowledge/reset-a-sensor?hsLang=en#smart-reset-a-smart-collection-sensor).  ### Fill Data Gaps Automatically ⚠️ *This feature will be rolling out over the last quarter of 2026 and may not be immediately available to all customers.* ⚠️ When you turn on **Fill Data Gaps Automatically**, the sensor will resend a limited number of readings that did not reach Conserv Cloud together with its next live reading. This means that after a short outage, the sensor can automatically fill in up to a few hours of missed readings when it comes back online. This setting fills gaps from short outages only. For longer outages, see [Fill Data Gaps Manually.](https://support.conserv.io/knowledge/infill-missing-data#fill-data-gaps-manually) **Note** This setting needs to be turned on for each individual sensor. The sensor will use slightly more battery power when the setting is on. **Before you begin**: Install the [Conserv Cloud Mobile App](https://support.conserv.io/knowledge/download-mobile-app?hsLang=en), sign in, and turn on Bluetooth on your phone. 1. Stand next to the sensor you wish to update. You must be within Bluetooth range. 2. Open the Conserv Cloud Mobile App, and tap **Connect to Sensor** *The app scans for sensors within Bluetooth range.* 3. Find the sensor by its serial number, and tap **Connect**. 4. Tap the gear icon in the upper-right corner. *The sensor settings open.* 5. Toggle on **Fill Data Gaps Automatically**.  To stop automatic gap filling, follow the same steps, and toggle off **Fill Data Gaps Automatically**.  ### Fill Data Gaps Manually **Before you begin**: Read all of the steps below before you begin. You must be near the sensor, and your phone must have a stable internet connection to upload the data. Find Missing Data Use one of these methods to find gaps from the last 90 days: - On the **Events** page, look for a sensor offline event. - On the **Analytics** page, select **Show gaps**. Here's [a short video to show you how you can do that](https://www.loom.com/share/fa7ac0a4ba034de8803f74801360e0ed). If a sensor often has gaps, you can upload its data on a regular schedule. See this article on [range testing](https://support.conserv.io/knowledge/test-sensor-range-via-the-conserv-cloud-mobile-app?hsLang=en) to help improve a sensor with a spotty connection. Upload Data from the Sensor 1. Stand next to the sensor you wish to update. You must be within Bluetooth range. 2. Open the Conserv Cloud Mobile App, and tap **Connect to Sensor**. *he app scans for sensors within Bluetooth range.* 3. Find the sensor by its serial number, and tap **Connect**. 4. In **Retrieve Last**, select how much data to upload from the dropdown. Select the smallest option that covers your gap. A smaller upload weill be faster. - 120 records ~ 1 day - 840 records ~1 week - 3600 records ~1 month - 10,800 records ~3 months) 5. Tap **UPDATE**, and stay near the sensor until the upload is complete. *A confirmation message appears on your phone, and you receive a confirmation email.* 6. Refresh your Analytics graph for the sensor with the period of the gap in view. If the gap does not look filled, see the Support section below. **Note**: The success message and confirmation email confirms that Conserv Cloud received the upload file. To check the result, see [Confirm the Upload](https://claude.ai/epitaxy/local_ce618de8-190c-4f75-8756-bc1c69971aac#confirm-the-upload). If the upload fails, the readings are still on the sensor. For more information, see [Support and Troubleshooting](https://claude.ai/epitaxy/local_ce618de8-190c-4f75-8756-bc1c69971aac#support-and-troubleshooting).  #### Confirm the Upload 1. In Conserv Cloud on your computer, refresh the **Analytics** page or use the circular arrow icon to the left of the **CREATE REPORT** button on the top right of the graph. 2. On the **Analytics** page, show the time period of the gap. 3. Select **Show dots**. *Readings from the sensor should fill the gaps.* If the gaps are still there, see [Support and Troubleshooting](https://claude.ai/epitaxy/local_ce618de8-190c-4f75-8756-bc1c69971aac#support-and-troubleshooting). ### Sensor and Firmware Requirements #### Sensors That Support Data Infill Data infill works only on **SCS-3 sensors with serial numbers c006000 or higher.** Earlier sensor models do not have the Bluetooth component to support data infill. Check and Update Firmware Each feature needs a minimum firmware version: | Feature | Minimum firmware version | | --- | --- | | Data infill | 1.6.0 | | Smart reset | 1.14.0 | On firmware older than 1.6.0, the sensor does not save time information with its readings. You cannot recover readings that the sensor recorded on that firmware. After you update, you can recover readings that the sensor records from that point on. Conserv recommends that you keep your firmware up to date. For more information about how to check and update firmware, see [Verify and Update Firmware Versions](https://support.conserv.io/knowledge/verify-and-update-firmware-versions?hsLang=en). **Warning**: Updating firmware resets the sensor. If your sensor is on firmware above 1.6.0 but below 1.14.0, fill any gaps in your data before you update firmware. ### Support and Troubleshooting If the manual upload fails, check the following items in order. #### Update the Mobile App Make sure that you have the latest version of the Conserv Cloud Mobile App. iPhones usually update apps automatically, but Android phones may not. 1. On your phone, open the App Store (iOS) or the Google Play Store (Android). 2. Find the Conserv Cloud Mobile App. 3. If **Update** appears, tap **Update**. *If **Open** appears instead, you have the latest version.* #### Check Your Internet Connection The manual upload uses your phone's internet connection to send the readings to Conserv Cloud. Your phone needs a strong Wi-Fi or cellular signal for the upload to go smoothly. If the sensor is in a basement or another place where your phone has a weak or unstable signal, the upload can fail. Move the sensor to a place where your phone has a better signal, and try again. #### Refresh the Bluetooth Connection If the app cannot connect to the sensor with a stable Bluetooth connection, or the connection drops during the upload because the screen turned off, a phone call came in, or another device interrupted the connection, try again. If retrying does not help, refresh the Bluetooth connection between your phone and the sensor. For more information about how to refresh the Bluetooth connection, see [Resolve Firmware Update Errors](https://support.conserv.io/knowledge/resolve-firmware-update-errors?hsLang=en#app-no-bluetooth-permissions). #### Contact Support If you still cannot upload the data, or you get successful upload messages but don't see the gap filled in the Analytics graph, [submit a support ticket](https://support.conserv.io/knowledge/kb-tickets/new?hsLang=en). In the ticket, please include the following information to speed up troubleshooting: - The serial number of the sensor (**c0xxxxxx**) - The model of your phone - The operating system and version of your phone, for example: Samsung S22 on Android 16 - The version of the Conserv Cloud Mobile App: for example, 1.7.13 - The quality of the Wi-Fi or cellular signal on your phone when you tried the upload - Your distance from the sensor when you tried the upload - Confirmation that the sensor is on, that is, the light on the back of the sensor flashes every 30 seconds. This confirms that the problem is not the batteries. - [Introduction](https://support.conserv.io/knowledge/introduction?hsLang=en) - [Technical Details and Specifications](https://support.conserv.io/knowledge/technical-details-and-specifications?hsLang=en#main-content) - [Sensor Specifications](https://support.conserv.io/knowledge/technical-details-and-specifications?hsLang=en#sensor-specifications) - [Other Sensor Information](https://support.conserv.io/knowledge/technical-details-and-specifications?hsLang=en#other-sensor-information) - [Gateway Specifications](https://support.conserv.io/knowledge/technical-details-and-specifications?hsLang=en#gateway-specifications) - [Conserv Cloud Specifications](https://support.conserv.io/knowledge/technical-details-and-specifications?hsLang=en#conserv-cloud-specifications) - [Installation and Setup](https://support.conserv.io/knowledge/installation-and-setup?hsLang=en#main-content) - [Initial Setup](https://support.conserv.io/knowledge/installation-and-setup?hsLang=en#initial-setup) - [Add, Move, Swap and Merge Sensors](https://support.conserv.io/knowledge/installation-and-setup?hsLang=en#add-move-swap-and-merge-sensors) - [Configure Conserv Cloud](https://support.conserv.io/knowledge/configure-conserv-cloud?hsLang=en#main-content) - [Organize and Manage Locations and Spaces](https://support.conserv.io/knowledge/configure-conserv-cloud?hsLang=en#organize-and-manage-locations-and-spaces) - [Import Data](https://support.conserv.io/knowledge/configure-conserv-cloud?hsLang=en#import-data) - [Configure Levels](https://support.conserv.io/knowledge/configure-conserv-cloud?hsLang=en#configure-levels) - [Configure Events and Alerts](https://support.conserv.io/knowledge/configure-conserv-cloud?hsLang=en#configure-events-and-alerts) - [Profile and Account Management](https://support.conserv.io/knowledge/profile-and-account-management?hsLang=en) - [Manage Sensors](https://support.conserv.io/knowledge/manage-sensors?hsLang=en) - [Integrated Pest Management](https://support.conserv.io/knowledge/integrated-pest-management?hsLang=en) - [Analytics and Reports](https://support.conserv.io/knowledge/analytics-and-reports?hsLang=en#main-content) - [Manage Analytics Data](https://support.conserv.io/knowledge/analytics-and-reports?hsLang=en#manage-analytics-data) - [Preservation Metrics](https://support.conserv.io/knowledge/analytics-and-reports?hsLang=en#preservation-metrics) - [Reports](https://support.conserv.io/knowledge/analytics-and-reports?hsLang=en#reports) - [Mobile app](https://support.conserv.io/knowledge/mobile-app?hsLang=en) - [Troubleshooting](https://support.conserv.io/knowledge/troubleshooting?hsLang=en#main-content) - [Troubleshoot Conserv Cloud Issues](https://support.conserv.io/knowledge/troubleshooting?hsLang=en#troubleshoot-conserv-cloud-issues) - [Troubleshoot Sensor Issues](https://support.conserv.io/knowledge/troubleshooting?hsLang=en#troubleshoot-sensor-issues) - [Troubleshoot Gateway Issues](https://support.conserv.io/knowledge/troubleshooting?hsLang=en#troubleshoot-gateway-issues) - [Troubleshoot Conserv Cloud Mobile App Issues](https://support.conserv.io/knowledge/troubleshooting?hsLang=en#troubleshoot-conserv-cloud-mobile-app-issues) - [Community, Support, and Updates](https://support.conserv.io/knowledge/community-support-and-updates?hsLang=en) - [Support](https://support.conserv.io/knowledge) - [Blog](https://support.conserv.io/blog) [![Chill listening crop-3](https://support.conserv.io/hs-fs/hubfs/Cnsrv_wmM_mix_rgb-1.png?width=108&height=24&name=Cnsrv_wmM_mix_rgb-1.png "Chill listening crop-3")](https://conserv.io) Copyright © 2026, Conserv Solutions Inc.
