Insteon and AFCI (Arc-fault circuit interrupter) Circuit Breakers

Years ago, first generation AFCI breakers were manufactured with poor tolerances which caused false triggers from a variety of common appliances, including Insteon powerline signals. Later generations of AFCI breakers are better engineered for real-world electronics and do well at avoiding being falsely triggered. Today there are no issues with using AFCI breakers and our Insteon devices. However, if the installer fails to follow standard wiring rules associated with AFCI circuits, you may experience issues.

Follow these important rules when wiring devices on AFCI circuits: 

  • Any branch circuits that feed receptacles before switches should be pigtailed connections at the receptacle. This is where you wire the incoming wire and the wire from the panel side and the wire going down stream together with a third wire “the pigtail” that goes to the outlet. DO NOT USE THE OUTLET AS A SPLICE TO CONNECT THE INCOMING AND OUTGOING WIRES BY STABBING THEM INTO THE BACK OF THE OUTLET
  • With AFCI breakers it is imperative that wall switches are connected to the same neutral that goes with that circuit. If switch box has two neutrals, only connect the switches neutral wire to the neutral from the circuit the switch is connected to. If an AFCI breaker wont reset after installing an Insteon switch it is because the wrong neutral was used. This can be a result of the electrician crossing neutrals in another box and not the fault of the wiring at the switch box itself. 
  • Loose or poor splices can cause a situation where an Insteon switch can trip an AFCI breaker. This is not the fault of the switch but the loose connection somewhere in the circuit.

If you are using AFCI breakers and experience false triggers with your Insteon system, please contact us at support@insteon.com and be sure to include the make and model of your AFCI breakers. 

Factory Resetting Insteon Devices

You can reset Insteon devices and restore them to factory default settings. The procedure to reset an Insteon device varies by device type. Factory resetting an Insteon device will erase all customized settings...

Sensor Shows Unknown Status

 
 

A sensor or other battery-powered device will show a yellow status circle and report "Unknown" if the Insteon Hub is unable to ascertain a sensor's status.

  • If your sensor was recently added to the Insteon App, tap the sensor's set button. This should update the status in the Insteon Hub and the app should begin tracking the status of the sensor.
  • If your sensor has been added to the Insteon App for a while and has only recently begun showing Unknown, it is possible that the Sensor's battery is low and needs to be replaced.

A wall-powered device may also show Unknown status. Ensure that the device is still connected to power and shows a red, green or white status LED. If not, check the power to the device. If power is normal, contact Insteon Support for additional troubleshooting or consult the product's Owner's Manual.

Port Forwarding Guides

The port forwarding set up is reliant upon the specific brand and model number of the router being used. The Insteon Hub (2012) and Insteon WiFi Cameras require forwarding for access to your network device from outside of your home network. The new Insteon Hub (2014) does not require port forwarding. Regardless of the router being used, the process of port forwarding is similar. Below is a list of port forwarding guides for popular routers:

Please follow the link below if your router is not listed.

Port Forwarding Guides

Understanding Linking

Links are One-Way

When linking Insteon devices, the links that are created are one-way.
 

Switch A will turn Switch B On and Off but
Switch B cannot turn Switch A On or Off

Links Remember a Device's State

The current state of the controlled device is stored in the link: On, Off, or Dimmed.

The switch will turn on the Lamp Dimmer to 75% brightness.


Controllers

Insteon devices that can turn other devices On or Off are called controllers.
 

Sensors, Switches, Keypads, and the Hub are common controllers.

Responders

Insteon devices that receive the command of a controller are called responders.

Switches, Keypads, Plug-In Modules and In-Line Modules  are common responders.


Controller-Only

Some devices, like sensors, can only control other devices.
 

Sup - Controller Only.png

The Motion Sensor will turn on the Switch but the switch cannot control the Motion Sensor.

Responder-Only

Some devices  cannot control other devices; these devices only receive Insteon commands.

The LED Bulb cannot control the Dimmer Switch but the Dimmer Switch can control the LED Bulb.


Grouping Devices

You may want to group together two devices, for example, in a virtual-three way configuration. For Insteon, this is called cross linking.

To mirror Switch A to Switch B so that they each control one another and the connected load, Cross Linking is necessary. 

Use Cross Linking

To Cross Link, simply turn on the devices and perform the linking process twice, once in each direction.

Link Switch A to Switch B and repeat to link Switch B to Switch A

Identifying Your Device Revision

As we continually improve our products by adding new features, some instructions may vary depending onthe particular revision of your product. See below for instructions on locating the revision of your product.

Non-Wired-In Devices

1. Look at the back of the unit (unplug the unit from the wall if it is a plug-in product)

2. Locate the sticker (on the label side) which contains the letter "V" followed by a number like "1.0"

 
 

In-Wall Switches, Keypads & Outlets

1. If the product is already installed, remove the trim plate

2. Locate the sticker (on the aluminum bracket) which contains the letter "V" followed by a number like "1.0"

 
 

DIN Rail Modules

1. Locate the sticker on the left side of the module which contains the letter "V" followed by a number like "1.0"

2. If ganged together, you may need to remove the DIN Rail module from its mounting rail

Mini Remotes

1. Locate the sticker on the back of the remote which contains the letter "V" followed by a number like "1.0"

Wireless Sensors

1. On Open/Close sensors, remove the top housing. For Motion sensors, remove the back access panel and the battery.

2. Locate the sticker which contains the letter "V" followed by a number like "1.0"

 
 

Insteon Glossary of Terms

Controller
T
he Insteon transmitter

Responder
The Insteon reciever

Blinking
LED turning on and off repeatedly

Dual-Band
An Insteon device that can send and receive both Insteon powerline signals and Insteon radio frequency signals

Ramp Rate
The speed at which the load fades on or off

On-Level
The preset brightness level a device will return to when turned on

Link
A one way association between a controller and responder

Linking
A method for associating Insteon controller buttons with groups of Insteon responders such that the responders instantly return to a memorized state when the button is pushed. Links can be made manually with the set button or using software.

Unlinking
The process by which an Insteon device can remove stored links. Just as with linking, unlinking is a one-way process and should be performed in both directions for devices that are both controllers and responders of each other, as in a 3-way switch scenario.

Multi-Linking / Multi-Unlinking
A special mode that allows more than one link to be either created or removed simultaneously, without laborious set button presses. When in linking or unlinking mode, an Insteon device will continue to link to other devices until the set button is tapped or four minutes have elapsed, whichever occurs first.

Factory Reset
A process that erases all stored links and reconfigures the device to factory defaults.

Load
The device that you are controlling (e.g. a light bulb, ceiling fan, etc.)

On/Off
A device that can control its connected load to turn on and off but cannot dim. Usually a relay-based device.

Retry
A 2nd (or subsequent) attempt by a controller to send an Insteon signal, usually after an acknowledge is not received from the responder in the expected time-slot.

Scene
Multiple devices respond to memorized states. For example, a dinner time scene turns on the dining table light, dims the kitchen lights to 10%, backyard lights turn off and the thermostat adjusts to 72º.

Set Button
A button on an Insteon device that is used for setting or changing its properties

Simulcast
A method for increasing the reliability of message delivery in a network. When a node in a network sends a message, every other node that hears the message retransmits it at precisely the same time based on a global clock, provided that the message has not already been retransmitted some maximum number of times. Message propagation is more robust because each node adds its energy to the signal, much like voices in a choir. Simulcasting is much simpler than message routing because there are no routing tables to maintain and nodes can join the network without any installation procedure.
