Communication Problems with Some Devices

The Insteon protocol is a much more robust communication protocol than the older X10 protocol that it replaces. However, Insteon users will sometimes find that their Insteon devices seem to communicate reliably between themselves, but that the ISY-26 will report "Communication Errors" on their power network. There are multiple reasons for this:

- The SmartHome PLM that is utilized by the ISY-26 can be less tolerant of weak Insteon signals and power line "noise" (interference) than the Insteon switches themselves.

- The ISY-26 and PLM require reliable "acknowledgements" of their "requests" to the Insteon devices. When not properly received for any reason, the ISY-26 will display an error. Sometimes this will prevent the completion of an ISY function.

Due to these two characteristics, a power line network must be as free as possible from substantial interference or signal loss, in order for the ISY-26 to provide error-free Insteon device monitoring and control.


The following tips may be helpful if communication problems are encountered:


- SmartHome AccessPoints can be used to improve network communications. Place these on opposite legs (sometimes called “phases”) of the power line mains. The AccessPoints provide their own internal utility to determine if they are on opposite legs of the powerline mains. (The older SignaLincs can be used for the same purpose.)

- Place the AccessPoints as close to the power line mains breaker or fuse box as possible. This will give any received signals the best chance of being propagated back throughout entire powerline network. This can provide a dramatic improvement in some cases. Again, be certain that the AccessPoints are placed on opposite legs of the power line mains.

- Stack or “piggy-back” an additional AccessPoint on top of the PLM. The AccessPoint can improve Insteon signal strength to enable the PLM to better receive and send signals. Many users have reported that this is an effective solution.

- The PLM should not be plugged into a power strip that has any type of surge-suppression incorporated, as this can weaken the Insteon signals. Likewise, certain models of GFCI outlets have also been reported to degrade Insteon signals (this, however, is not true for all GFCIs).

The next point is probably one of the most important:

- Use power line filtering devices (such as the SmartHome Filterlinc) on all potential signal “sinks” and noise generating devices in your home. Devices such as computer power supplies, televisions, home theater systems, etc, can all act as “signal sinks” that degrade the Insteon signals on your power line network. Conversely, devices such as low voltage halogen lighting , CFLs (compact fluorescent light bulbs), etc, can generate interference patterns on your power line network that can cause the PLM or even other Insteon devices to miss Insteon control signals, which get lost in the background noise on the power line.

Even if you have previously installed some power line filters on your system, you may find that more may be required if problems still persist. Remember that the bottom outlet on the FilterLinc is the “filtered” outlet.

- For hard-wired halogen lighting, in-line noise suppressors can be used (such as the Levition Noise Block model 6287).

- Some CFLs are prone to producing much higher levels of powerline noise than others. CFLs that are producing excessive line noise can be replaced with those that produce less interference.
