Defender Slim™ Resource Center

Slim sensors should be placed in or near appliances, equipment, plumbing, or in a temperature-controlled room. Examples include:

• In a bathroom, kitchen, laundry, or utility room
• Under a sink, behind a toilet
• Next to a boiler, water heater, or sump pump
• In a temperature-controlled basement near a pipe
• In a temperature-controlled room where freeze is of concern
• Where leaks or freeze loss have occurred in the past

Slim sensor monitors for water leaks and potential freeze conditions.

Slim sensor is powered by a long lasting, non-replaceable lithium battery.

The battery is designed to last for over 5 years. Actual battery life will vary based on how often alerts occur as well as device connectivity.

Please contact your insurance company agent or representative to discuss placing an order for more sensors.

Slim sensors use the Amazon Sidewalk® network. The sensors do not utilize cellular connectivity and can communicate even when your Wi-Fi is offline, through other Amazon® hub devices in your area.

Slim sensors are battery-powered and will continue to monitor for leaks and issue audible alerts even if the location loses electric power. Additionally, the sensor will continuously attempt to communicate via other Amazon Sidewalk® connected gateways or devices nearby.

Each sensor has its own

1. Unique Device ID code (found on the box behind the sensor) and
2. 7-digit alphanumeric Activation Code (found on the back of sensor and inside the sensor packaging.

The 7-digit code can be used to activate the sensor on any mobile phone or laptop. Users with a mobile phone tend to find that scanning the QR code is simpler.

If you believe you should have an account with us, please try the alternate communication method that you provided (e.g. try sending the code to your email if you submitted a phone number). If you are still having trouble, please use our contact form to let us know and a member of our team will contact you.

Slim sensors needs to establish a connection with the Amazon Sidewalk® network to provide optimal protection for your location. Higher floors tend to have greater likelihood of connectivity. Once a device has successfully connected to the network, other sensors that are having difficulty accessing the network can report their status through our patent pending Meshify Relay™ technology.

Slim sensor will attempt to connect to the Amazon Sidewalk network for 24 hours. The user will be notified if the connection attempts have been unsuccessful. If connection attempt has been unsuccessful, it is recommended to relocate the sensor to a different location.

The user will be notified via email should the Slim sensor be unavailable to connect for 24 hours. Slim sensor connection status will always be visible in the Protect app.

Purple: During activation, the LED will blink PURPLE while the sensor is connecting to the Amazon Sidewalk® network.

Green: During activation, the LED will blink GREEN when it has successfully connected to the Amazon Sidewalk® network.

NOTE: After initial confirmation, the LED will turn off to conserve power.

The sensor will continue connection attempts in the background. If it still has not connected after 24 hours, your device will be in Audible Only mode and still issue an audible alarm when water is detected.

To ensure optimal detection of leak events, there are 2 sensor placement approaches:

1. Flat on a horizontal surface, with the Meshify bird logo facing towards the ceiling. Ensure the leak pins are not covered or blocked.
2. Vertically against a baseboard or cabinet, by utilizing tape strips found on the back of the sensor. Before securing, ensure leak pins are as close to the nearest horizontal surface as possible, with the water drop icon facing the floor.

Slim sensors connect to Meshify servers utilizing the Amazon Sidewalk® network provided by a nearby Amazon® hub device, such as an Echo® or Ring®. You do not need to own an Amazon® hub device for the Slim sensor to connect to the internet.

In locations lacking Amazon Sidewalk® network connectivity, the Slim sensor will still continue to protect your location via an audible buzzer that will ring when water is detected.

You can move the Slim sensors to another location on the property. However, it is important that you update the location information, so in the event you are alerted there’s accurate location information and the device can be easily found.

Currently, the battery life of the sensor is not visible on the dashboard.

To turn off the Slim sensor, press and release the button 2 times, followed by a long press (hold then release) for 3 seconds. The sensor will emit a single audible tone then power off.

When device is turned on, press and hold power button for 3 seconds then release. The Slim sensor will start blinking PURPLE. The LED will blink GREEN if connected or YELLOW if not connected (this process may take up to 2 minutes based on network availability).

The sensor will beep and the LED will turn green when the device is connected. You can always check your device connection on the Slim dashboard at slim.meshify.com.

Your Defender Slim is either joining the network, which can take up to 24 hours, or it is currently out of network range; SMS and email alerts are unavailable, but the sensor’s built-in audio alarm will still sound if water is detected.

Slim sensor sends alerts via SMS, push notifications, and email as well as phone calls. Additionally, the Slim sensor also issues an audible alert when leaks are detected.

A mobile app is not required, and information about the sensors can be found at slim.meshify.com.

You will receive Slim sensor alerts based on the notification preferences you define as a part of the activation process. Notifications options include SMS, push notification, and email alerts, when issues are detected. The Slim sensor also issues an audible alert when leaks are detected.

Additional contacts may be added to your account via the dashboard at slim.meshify.com.

Amazon Sidewalk® is a shared network designed to enable low-bandwidth IoT devices to connect to the internet over longer distances than typical Wi-Fi would allow. It’s built into some Amazon devices like Echo® speakers and Ring® cameras, enabling creation of a low bandwidth mesh network for smart device connectivity.

Amazon Sidewalk® uses end-to-end encryption to ensure that data sent through the network is secure. Each user’s data is kept separate, and it’s designed to prevent malicious users from gaining access to other users’ devices.

Note: For clients or policyholders who require more detail, please reference “Privacy and Security” PowerPoint slide.

Because Amazon Sidewalk® is an IoT network that is powered by Amazon® devices across the neighborhood, Slim sensors can establish connectivity even when Amazon Alexa® or Ring® devices are not at your location.

In fact, the neighborhood network is one of the key benefits of Amazon Sidewalk®-enabled Slim device. There are many Meshify Defender Slim™ sensors installed at locations where there is no Amazon® hub device in the property.

In these situations, the actual strength of your network is dependent upon the relative availability of Amazon Alexa® or Ring® devices in your area.

No, the Slim sensor does not operate via Amazon Alexa®.

While both Slim Sensors and Apple AirTags® rely on long-range, low-power wireless communication, their purposes are different: Slim Sensors are meant for environmental monitoring and extending connectivity for IoT devices, while Apple AirTags® are primarily designed to help you track physical items via a crowdsourced network of Apple® devices. They share some technological similarities, particularly in how they use a crowdsourced network to extend their connectivity, but they are meant for different use cases.

Slim sensors do not collect nor share personally identifiable information or precise location data. All sensor data is encrypted and anonymized. To support and improve Amazon Sidewalk® connectivity and coverage, Slim sensors may share limited, anonymized device and network information, as well as anonymized approximate location data, with Amazon. This information is used exclusively for network performance and coverage purposes and does not include personal or exact location details.

Slim sensors capture environmental data related to water leaks and temperature.

Your information will not be used for targeted advertising or promoting Amazon® products.
