3-Way Two Gang Switch Installation GuideUpdated a year ago
How an iotty Smart Switch 3‐Way Setup works:
It is important to note that for the iotty switches, the iotty “L” lead (Live/Hot) must be connected to a constant source of power and the iotty “N” lead must be connected to the Neutral. This ensures the switch has a constant power supply for the Backlight and Wi-Fi modules.
- Power flows from the Main Power to the first switch box where it is connected to a Traveler wire, Neutral, and the iotty “L” Lead.
- One (either) of the two Traveler wires can be capped off at both ends as it will not be used.
- The Traveler wire carries the power to Switch Box 2 where it connects with both the iotty “L” Lead and the iotty “L1” Lead.
- Then the iotty “L1” lead is connected with the load wire.
- When the switch is pressed, the relay between “R1” and “L1” will be opened or closed, preventing or allowing, respectively, the power to flow all the way from the Main Power to the Load.
- That power will flow through each pass-through box through the connected Traveler wires until it reaches the control box and powers the load.
- Once power makes it to the load, it returns to the Main Power through the series of Neutral wire connections. The Neutral wire connects the load to Switch Box 2.
- Inside Switch Box 2, Neutral wire is connected with neutral wire. Inside Switch Box 1, Neutral wire is connected with neutral wire, thus completing the circuit.
- Both iotty Smart Switches also connect the power into the neutral wire connections as illustrated to ensure they have a constant power flow.
- Finally iotty smart switches are linked from a Multi-Way Automation in the iotty App. Information for creating Multi-way Automations can be found below, or in our iotty app instructional guide under ‘Automations’
Converting a Common Traditional 3‐Way Setup to an iotty 3-Way Setup:
**WARNING: For safety, always turn off power at the breaker before doing any electrical work**
- There are multiple ways to achieve a 3‐way setup so you should confirm with an electrician your setup. 1. The following instructions are based on converting a 3‐way setup. To the iotty 3‐way setup. If your existing 3‐way setup does not match this description, your electrician should still be able to achieve the required iotty 3‐way Setup.
Identifying your wires for your 3-Way switch:
If you are unsure of your wires in your box please watch our Identifying your wires tutorial video:
Iotty Multi-Way Install Instructions:
1) Turn Power at the breaker OFF
2) Verify power is off. At each switch, label the Common wire [each switch will have two terminal screws of the same color and a common screw of a different color. Mark the wire connected to the different colored screw].
Note: The Common wire in the pass-through box has the power from the breaker, the same wire (Common) in the control box is the load as the traveler wire is what brings power to the control box.
3) Determine which box has the line (power) coming into it and which box has the load going out. The box that has the line coming in will be wired as a pass‐through box.The box that has the load going out will be wired as the control box.
Note: These instructions apply for two separate 2 gang switches that have 2 separate switches connected controlling the same fixtures:
4a) *Start in Switch Box 1 (Pass-through Box)*
- Disconnect the previous switches, labeling the Common, Traveler, and Neutral wires
- Neatly tuck the Ground wire into the back of the box, it is not needed
- Connect the “N” Lead on the iotty switch to the Neutral in the box associated with the right most circuit (this ensures if there are more than one circuit you connect the “L” and “N” to the same one)
- Connect the right Common (live) wire and one of the right Traveler wires with the “L” Lead on the iotty switch. (Note: the traveler wires are connected to the same color screw on a traditional 3-Way switch)
- Connect the left Common (live) wire with one of the left Traveler wires.
- Cap off remaining Traveler wires separately.
- Cap off both of the “RL2” Leads on the iotty switch
- Cap off both of the "RL1" Leads on the iotty switch
4b) Finish in Switch Box 2 (Control Box)
- Disconnect the previous switches, labeling the Common, Traveler, and Neutral wires
- Neatly tuck the Ground wire into the back of the box, it is not needed
- Connect the “N” Lead on the iotty switch to the Neutral in the box associated with the right most circuit (this ensures if there are more than one circuit you connect the “L” and “N” the same one)
- Connect the active (used in Box 1) Traveler wire for the right switch, one of the "RL2" leads, and the “L” Lead on the iotty switch
- Connect the active (used in Box 1) Traveler wire for the left switch and one of the "RL1" leads on the iotty switch
- Cap off the other unused Traveler wires by themselves.
- Connect the unused "RL2" lead on the iotty switch to the corresponding Common (load) wire for the right switch
- Connect the unused "RL1" lead on the iotty switch to the corresponding Common (load) wire for the left switch
**Please ensure the same traveler wire is used in both boxes for each 3-way**
5) Install the Faceplate
- With your hands only, carefully position the Faceplate so that the little circle is located at the bottom of the rectangle and apply gentle pressure with two fingers at the top and bottom of the Faceplate, you will hear the plate attach to the Backplate.
- Once installed, the Faceplate should not be loose or move.
- If necessary, to remove, pull away at the bottom of the device until you hear a click then lift off. Do not pull the Faceplate when removing, lift only. Please see our Help Article here for more information.
6) Turn Power at the breaker ON
