Hello X-Senser! You may be experiencing issues with connecting your base station to the app. To assist with this problem, we would like to share some common causes and troubleshooting steps that may help resolve the connectivity issues:1. Network Band Compatibility❌ 5 GHz WiFi or Dual Band (2.4 GHz + 5 GHz) networks are not supported.✅ Solution: Please ensure you are connecting to a 2.4 GHz WiFi network. If your router uses both bands under the same name (SSID), consider splitting them via your router settings and connecting only to the 2.4 GHz band. If you need help with this, we recommend contacting your router manufacturer.2. WiFi Credentials & Signal Strength❌ Incorrect network name or password / Weak signal strength.✅ Solution: Move closer to the router and ensure the WiFi password is entered correctly.3. Device & App Settings❌ Bluetooth disabled / Outdated app or firmware.✅ Solution: Ensure Bluetooth is enabled on your phone and that you are using the latest version of the app.4. Router-Specific Issues❌ MAC address filtering / IP address conflicts / Network congestion.✅ Solution: Try restarting your router to refresh network assignments and clear any connection issues.5. Network Configuration❌ Use of guest networks, VPNs, or restrictive firewalls.✅ Solution: Connect to the main WiFi network, disable any active VPN, and ensure that firewall ports 8883, 443, and 53 are open.Please go through the above steps and see if any of them apply to your situation. If the issue persists, please feel free to reach out to our team!

Hello X-Senser!Thank you for your interest in X-Sense products!If you're curious about the different ways our smoke alarms, CO alarms, and combination detectors connect, you're in the right place! This article will explain the unique connection capabilities of each type of device we offer.Understanding X-Sense Device ConnectionsHere's a breakdown of the different types of devices we currently offer, categorized by their connection capabilities:Standalone Models: These devices work independently. They don't interconnect with other alarms or connect to an app. When a hazard is detected, only that specific unit will sound a local alarm.Examples: XS01, SD2J0AX, XC01-R, SC07Interconnected Models: These units wirelessly connect with each other using RF technology. This means if one unit detects smoke or CO, all connected units will sound an alarm at the same time. Please note, these models don't support app connectivity.Examples: XS01-WR, SD19-W, XC01-WR, SC07-WApp-Connected Models: These models link directly to the X-Sense Home Security app via 2.4 GHz WiFi. This allows you to manage your devices remotely, receive alerts, or silence alarms right from your smartphone. However, they don't support interconnection, so each device operates independently.Examples: XS01-WX, XC04-WX, SC07-WXLink+ Pro Series: This series offers the best of both worlds! When used with a compatible base station (sold separately or included in kits), these devices support both wireless interconnection and app connectivity. You get real-time alerts through the app and synchronized alarms across all interconnected units.Examples: XS01-M, XC01-M, SC07-MR, XP0A-MRChoosing the Right ModelIf your main goal is to have one alarm trigger all others simultaneously and also receive app notifications, we strongly recommend choosing a Link+ Pro model along with a base station.Please feel free to reach out to our service team if you need help selecting a suitable model or have any further questions!

Here are some tips for you： 1: Turn on the push notification permission on the phone.  2: Move the base station closer to the router and reduce obstacles like metal walls and thick walls. The distance between the base station and the router should be within 164 ft (50 m).  3: Move the device closer to the base station and reduce obstacles. The maximum distance between the device and the base station in an open environment is 1,640 ft (500 m). 4: Move the mobile phone closer to the router. Make sure the network connection between the router and the mobile phone is normal.

If you have not connected any detectors to the base station, please just press "Remove Device" in the base station Settings.If you have connected any detectors to the base station, please remove the detectors first, and then remove the base station in Settings.

Here are the troubleshooting steps to try:  1.Please check if the device's battery power is sufficient.  2.Please remove the device from the app. Then, please reset the device (reset method: quickly press the test button 4 times, then long press until you hear a beep and release). Finally, please place the device next to the router, take out the device battery, press the test button a few times to drain the remaining power, then reinsert the battery and try adding the device to the app again.

We have set up a heartbeat package inside the device, which will detect the network status every 11 hours and automatically reconnect. If the network cannot be connected for three consecutive times, the APP will be updated to offline. Once an alarm occurs after the device is offline, it will reconnect immediately and will not affect the alarm push.

Here are some tips that you can use better. Could you please give it a try? 1.Make sure you connect smoke detector to 2.4GHz Wi-Fi network (incompatible with 5GHz Wi-Fi network). If your home Wi-Fi router is a 2.4 and 5 GHz dual band that operates with a single SSID name, please refer to your Wi-Fi router manual to create separate SSIDs for the 2.4 and 5 GHz channels. You can also select "General Router Setting Method" in the X-SENSE app in the network configuration process to learn more about the corresponding setting method. 2.Make sure Bluetooth is turned on on your phone.

Here are a few tips for your better use. Would you please try them? 1. Please place the device next to the router to see if the network is stable. Please install the device closer to the router. 2. Too many devices have been added to the router. You can check the maximum number of compatible devices in the router settings. The closer to the critical value, the easier it is to be squeezed out of the line. 3. After the device is online, if the APP still shows offline, please kill the current APP process and try to re-enter the APP. In addition, our device has a heartbeat package set up inside, which will detect the network status once every 11 hours and automatically reconnect. If the network cannot be connected for three consecutive times, the APP will be updated to the offline status. Once the device is offline and an alarm occurs, it will reconnect immediately without affecting the alarm push.

This may be caused by firewall blocking. Please check the firewall settings and open TCP port 8883 and UDP port 53 in the firewall.

The device can be added to WiFi directly without going through a base station. Please select Wi-Fi Smoke Alarms/Wi-Fi CO Alarms/Wi-Fi Combination Alarms in the APP and then add the device.

To optimize energy consumption, our devices are equipped with a heartbeat packet feature:For standalone WiFi devices, a network status check is performed every 11 hours, and the device will automatically reconnect if necessary.For Link+Pro devices, a network status check is performed every 15 minutes, and the device will automatically reconnect if necessary.If the device fails to connect to the network for three consecutive attempts, the app will update the device status as offline. However, even if the device is offline, it will immediately reconnect in the event of an alarm to ensure that alarm notifications are sent without any interruption.

When the XS01-M Smoke Detectors display as online in the X-Sense Home Security app, the device testing will only be applied to the current device you are operating regardless of whether you short-press or long-press the Test/Silence button. However, when a smoke detector detects fire hazards, the alarm signal will be dispatched to other alarms including the base station. They will all go off and an alert notification will be pushed to your smartphone.If you do not have an SBS50 Base Station or your XS01-M Smoke Detectors display as offline in the app, you can test their connectivity by holding down the Test/Silence button on any one of the alarms. Once an alarm detects fire hazards, other alarms in the network will go off as well, which is similar to the situation described above. Note: You will be unable to receive the push notifications in this situation.

XS01-M is a Link+Pro device. Without a base station, you can pair the devices with each other to achieve interconnected alarm functionality.With a base station, simply add the XS01-M device to the base station. Once added, XS01-M will automatically have interconnected alarm functionality, unaffected by any base station malfunctions or offline status. Additionally, you can remotely control the device through the X-SENSE Home Security App.To add the offline XS01-M device to the base station, please reset it first. Resetting steps: Quickly press the test button four times and then press and hold it until you hear a beep sound, then release.Regarding the interconnected alarm functionality: When one detector is triggered, all other detectors will sound the alarm.

If you are unable to connect to the cloud server, please perform the following checks:1.Check your firewall settings. Make sure that TCP port 8883 and UDP port 53 are open in your firewall settings.2.Is your router a dual-band router that supports both 2.4 GHz and 5 GHz frequencies? If it is, try connecting the device to a 2.4 GHz hotspot created by your phone to see if it can establish a connection. If it can connect successfully, it indicates an issue with the router. Our devices only support 2.4 GHz networks, and dual-band routers that combine both 2.4 GHz and 5 GHz frequencies may cause connection issues.
