What if your sliding door could detect when your pet approaches, recognize its authorized Bluetooth tag, and open only when the conditions you've chosen are met?
Meet DuoMotionX, the wireless secure motion sensor designed for the SmartSlydr automatic sliding door system.
DuoMotionX combines a PIR motion sensor, Bluetooth PetPass authorization, and a built-in push button to give you more control over how your sliding door opens.
Unlike a basic motion-triggered opener, DuoMotionX lets you select how the door responds. You can configure secure access for your pets, require owner approval through Send Request Mode, use the built-in button for people, or enable general motion-based access.
One sensor. Four Smart Modes. Multiple ways to open your door.
What Is DuoMotionX?
DuoMotionX is a wireless Passive Infrared (PIR) motion sensor with an integrated push button, designed to work with SmartSlydr.
A PIR sensor detects changes in infrared energy caused by movement within its detection area. DuoMotionX adds configurable operating modes so motion doesn't always have to result in the door opening.
Depending on your selected mode, DuoMotionX can require:
- Motion detection together with an authorized Bluetooth PetPass
- A press of the center button
- Motion alone
- Either a button press or motion
For secure pet-access modes, PetPass can also be configured for Automatic Mode or Send Request Mode.
This gives you flexibility to create an access system that fits your pets, family members, and home environment.
How Does DuoMotionX Work?
DuoMotionX communicates with SmartSlydr and detects movement in the configured area beside the sliding door. What happens next depends on the Smart Mode selected in the LycheeThings app.
For example, in Secure Pet Only Mode:
Pet approaches the sliding door
↓
DuoMotionX detects motion
↓
SmartSlydr confirms an authorized Bluetooth PetPass
↓
The selected PetPass mode determines what happens next
- If PetPass is set to Automatic, SmartSlydr opens the door.
- If PetPass is set to Send Request, SmartSlydr notifies the owner and waits for approval before opening.
This combination of motion detection, PetPass recognition, and configurable access behavior is the central idea behind DuoMotionX.
Four Smart Modes: Choose How Your Door Opens
DuoMotionX offers four Smart Modes to accommodate different needs.
| Smart Mode | How SmartSlydr Responds |
|---|---|
| Secure Pet Only Mode (Motion + PetPass) | Motion and an authorized PetPass must be detected together. PetPass can be set to Automatic Mode (door opens automatically) or Send Request Mode (owner approval required). |
| Pet and Human Mode (Motion + PetPass or Push Button) | Pets: Motion plus authorized PetPass, with Automatic or Send Request behavior. People: Press the built-in center button to open the door without PetPass. |
| Button Only Mode (Push Button Only) | The door opens only when the center button is pressed. Motion detection does not trigger an opening. |
| Open For Everyone (Any Motion or Push Button) | Motion detection or pressing the center button opens the door. PetPass authorization is not required. |
Let's explore what each mode means in everyday use.

1. Secure Pet Only Mode — Motion + PetPass
Secure Pet Only Mode is designed for households that want to restrict pet-triggered access to authorized PetPass tags. Two conditions must be met:
- Condition 1: DuoMotionX detects motion.
- Condition 2: SmartSlydr detects an authorized PetPass.
Motion alone does not trigger an opening in this mode.
Automatic PetPass setting
Motion detected + Authorized PetPass
↓
Door opens automatically
This is useful when you want hands-free access for an authorized pet but also want the sensor to detect an approach within a selected area.
Send Request PetPass setting
Motion detected + Authorized PetPass
↓
Owner notified
↓
Owner approves
↓
Door opens
This is useful when you want both secure motion detection and owner approval. For example, your dog may approach the doorway wearing its PetPass, but you may want to decide whether to allow access during the evening. Secure Pet Only Mode can be configured to support that behavior.
2. Pet and Human Mode — Motion + PetPass or Push Button
Pet and Human Mode is designed to serve both pets and people. It provides two separate access methods.
For pets: DuoMotionX detects motion together with an authorized PetPass. The PetPass can be configured in either of two ways:
- Automatic: Door opens when both conditions are met.
- Send Request: Owner receives a request and approves access before the door opens.
For people: A person presses the center button on DuoMotionX, and SmartSlydr opens the door without requiring a PetPass.
Example: One door for your dog and family
Your dog approaches the patio door wearing PetPass. DuoMotionX detects motion and the authorized tag, then follows the selected Automatic or Send Request setting. Later, a family member wants to go outside — they press the DuoMotionX center button to open the door.
Both can use the same DuoMotionX sensor, with different access methods. This is a practical solution for families that want pet automation without sacrificing convenient human access.
3. Button Only Mode — Push Button Only
Button Only Mode turns DuoMotionX into a wireless door-opening button. The door opens only when the center button is pressed; motion does not trigger the door.
This mode is helpful when you want a simple button beside the sliding door without enabling automatic motion detection. For example, someone using a walker or wheelchair may prefer a button mounted at a reachable height instead of manually sliding a heavy patio door.
The best mounting location depends on the person's reach and the surrounding doorway layout.
4. Open For Everyone — Any Motion or Push Button
In Open For Everyone Mode, DuoMotionX can open the door when motion is detected or the center button is pressed. An authorized PetPass is not required.
This mode can be useful for households that want general hands-free access through a sliding door. For example, someone approaching with their hands full may prefer the door to open from motion detection rather than having to press a button.
Important: Because motion alone can trigger the door, this mode is best used where that behavior is appropriate for the doorway and surrounding environment. For PetPass-restricted access, select Secure Pet Only or Pet and Human Mode instead.
DuoMotionX Works With Automatic and Send Request PetPass Modes
One of DuoMotionX's most useful capabilities is that its two secure pet-access Smart Modes support both PetPass operating options.
Automatic Mode
Motion + Authorized PetPass = Automatic Door Opening
The owner can receive a door-operation notification after the opening.
Send Request Mode
Motion + Authorized PetPass = Owner Approval Request
The owner approves access in the LycheeThings app before SmartSlydr opens.
This means you can choose whether your pet gets independent access or needs your approval while keeping the same secure motion-detection setup.

Why Combine Motion Detection With Bluetooth PetPass?
Some dogs spend a lot of time near the sliding door. They may watch birds, rest beside the glass, or walk past the doorway throughout the day.
A proximity-based PetPass system may sometimes detect a nearby pet even when it isn't intentionally approaching the door to go outside.
DuoMotionX adds another condition. In secure pet-access modes, the system requires movement within the configured detection area together with an authorized PetPass. You can also adjust the detection direction to focus on the path your pet normally takes.
This helps you fine-tune the system to your home rather than relying on tag proximity alone.
DuoMotionX adds another way to control when pet access is triggered.
Five Adjustable Detection Positions
Every home has a different layout. A narrow hallway, a large living room, and an outdoor patio may require different detection directions. DuoMotionX offers five selectable positions using its magnetic mounting system.
| Position | Detection Area | Typical Use |
|---|---|---|
| Down | Centered, close range of approximately 2–3 feet | Focused detection directly in front of the sensor |
| Left Narrow | Narrower detection toward the left | Controlled left-side approach |
| Left Wide | Wider detection toward the left | Broader left-side approach |
| Right Narrow | Narrower detection toward the right | Controlled right-side approach |
| Right Wide | Wider detection toward the right | Broader right-side approach |
How Do You Change the Detection Position?
- Pull DuoMotionX away from its magnetic wall plate.
- Rotate the sensor to the desired position.
- Snap it back onto the wall plate.
No additional drilling is required to change the sensor's detection direction.
Tip: Start with the Down position. Then adjust the direction or sensitivity if SmartSlydr responds earlier or later than desired.
Two DuoMotionX Sensors: One Inside and One Outside
For motion-based access from both sides of the sliding door, SmartSlydr recommends using two DuoMotionX sensors.
- Inside sensor: Detects approaches from inside the home.
- Outside sensor: Detects approaches from the patio or backyard.
This provides a complete two-way motion-detection setup.

Example: A Dog Going Out and Coming Back In
When the dog approaches from inside, the indoor DuoMotionX detects movement and checks the selected secure pet-access conditions. When the dog returns, the outdoor DuoMotionX handles the approach from outside.
Each sensor can be configured to suit its location and the pets authorized to use it.
Control Which Pets Can Enter or Exit
DuoMotionX allows individual PetPass tags to be enabled or disabled on each sensor. This is especially useful for households where different pets have different access needs. For example:
- Dog: Allowed to go outside and come back inside.
- Indoor-only cat: Not authorized on the indoor sensor, but optionally authorized on the outdoor sensor if return access is desired.
With separate sensors, you can configure which authorized pets can trigger access from each side. This provides more flexibility than a permanent pet-door opening that every animal can use.
DuoMotionX Supports Up to Six PetPass Tags per Sensor
DuoMotionX supports up to six PetPass tags per sensor, and each PetPass can be individually enabled or disabled.
This gives multi-pet households more flexibility when configuring access. For example, you could authorize different dogs or cats on the indoor and outdoor sensors according to their needs.

Is DuoMotionX Useful for Accessibility?
Yes. DuoMotionX can provide alternative ways for people to operate a SmartSlydr-equipped door. Depending on the selected Smart Mode, users can open the door using:
- The built-in push button
- Motion detection
- Other SmartSlydr controls such as the mobile app or voice assistants
The wall-mounted button can be positioned to suit a person's reach, and motion-based access can be useful when someone approaches the door with their hands full.
For seniors, wheelchair users, and people with limited mobility, reducing the need to manually slide a heavy patio door may make everyday access more convenient.
Choose the mounting height, detection coverage, and access mode that best suit the user's mobility and security needs.
How to Install DuoMotionX
DuoMotionX is designed for wireless installation beside your sliding door. According to the official setup guide, a typical installation takes approximately 10–15 minutes.
