Appendix H: Troubleshooting INSTEON Communication
Issues
It is important to have a pair of INSTEON AccessPoints or other INSTEON RF devices (or an
INSTEON-compatible hardwired coupler) installed to ensure good communications
between both legs of power in your home. See Smarthome's documentation for ensuring
your AccessPoints are installed on opposite legs of power. We recommend placing them as
close to your electrical panel as possible.
An AccessPoint (or other INSTEON RF receiver, such as their 2413S Dual-Band PLM) is also
required to communicate with INSTEON RF devices.
Most INSTEON devices use powerline technology to communicate with one another. Some
devices on in your home may interfere with device communications. Some known
offenders are:
Low voltage lighting
Fluorescent lighting
CFLs
Desktop computers and notebooks
Surge protectors
UPSs
In many cases these devices can exist on your powerline with no problem. But, if you are
experiencing communication issues, we highly recommend unplugging any devices you
have on the above list. Once you establish reliable communications, add the devices back in
one at a time to find the cause. Most troublesome plug-in devices can be filtered using
FilterLincs from Smarthome.
Because the ISY sends and receives all INSTEON signals through the PLM, we highly
recommend plugging it in to an outlet away from potentially noisy electrical devices, such
as PCs and UPSs, and as close to your electrical panel as possible. DO NOT plug your PLM
into a surge protector or UPS. We also highly recommend installing an AccessPoint as close
to your PLM as possible.
