Your safety is important to us. Electricity is dangerous and can cause personal injury and property damage if handled improperly. A working knowledge of electrical installation is required to install this product. If you are not comfortable working with electricity, don't attempt to install the iDevices Wall Switch and seek professional assistance from a qualified electrician.
Note: For 3- and 4-way setups, communication between the Wall Switches is via Bluetooth® technology. In order for the Wall Switches to communicate properly, all Wall Switches need to be replaced with iDevices Wall Switches.
The distance between the primary and secondary switches can range depending on the Bluetooth signal strength between them. Typically they best perform less than 30 feet apart, but that can vary depending on the environment. To learn about the Bluetooth connection and to ensure the switches have a strong Bluetooth connection, visit: iDevices Blog
Installation - 3-way:
3- and 4-way switches are used to control one or more lights/fixtures from multiple locations, such as the top and bottom of a flight of stairs.
1. Turn OFF the power at the circuit breaker.
2. Remove the existing faceplates and switches from the gang boxes. Take a photo of the existing wiring for future reference.
3. Confirm that each gang box contains a neutral wire (typically white). If there are no neutral wires present, you may need to run additional wires, please consult a qualified electrician. 
Note: Your home’s wiring may differ; please consult a qualified electrician
4. Remove the wires from the common terminal on both of the existing switches and cap with the provided wire nuts. Note: The common terminals usually have a screw that is either black or copper in color.
5. Turn the power back ON at the breaker. Using your voltage detector, identify which of the two wires you removed from the common terminal is energized. This is the “line” wire. Mark this wire as the Secondary (S) Switch Position. You will need to refer to this during the Wireless Communication Setup.
The wire you removed from the common terminal that is not energized is the “load” wire. Mark as the Primary (P) Switch Position. You will need to refer to this during the Wireless Communication Setup.
6. Install the iDevices Wall Switches according to the diagram. Ensure the wire nuts are securely fastened.
7. Install the Wall Switches into the gang boxes and install the faceplates.
8. Extend the pull out tab on the front of the Wall Switch connected to the line wire (identified in step 5). Using a ballpoint pen, put an “X” in the box to indicate that this is the secondary Wall Switch.
9. Extend the pull out tab on the front of the Wall Switch connected to the load wire (identified in step 5). Using a ballpoint pen, put an “X” in the box to indicate that this is the primary Wall Switch.
10. Turn the power back ON at the circuit breaker and confirm that the LED on both Wall Switches light up purple.
Installation - 4-way:
In a four-way installation you will follow the same process as a three-way installation which is listed above. However, in a four-way setup you'll have one additional switch that is specifically a 4-way switch. You'll notice that this switch has 2 red wires and 2 black wires connected to it (If your 4-way switch has 2 white wires and 2 red wires connected to it, your configuration is not compatible with the iDevices Wall Switch).
Remove all wires from the 4-way switch and cap both red wires with wire nuts. You will then tie the 2 black wires along with the black "Line" wire on the iDevices Wall Switch together with a wire nut. Connect the white wire on the iDevices Wall Switch to the neutral wire (usually white) in the gang box and cap with a wire nut. Finally, cap the remaining red wire on the iDevices Wall Switch.
This Wall Switch will serve as another secondary Wall Switch. Pair it to the primary Wall Switch in the same manner as described in the 3-way install instructions above.
