According to Wikipedia Z-Wave operates at 

 

https://en.wikipedia.org/wiki/Z-Wave

 

908.42 MHz in the U.S. and Canada

 

However according to the Insteon Technology page

 

http://www.insteon.com/technology/

 

915 MHz

 

My main question is if you have too many Z-Wave and Insteon devices if they will interfere.

 

Has anybody experienced interference between Insteon and Z-Wave?

Thanks!

Insteon is actually 914.975MHz. The two frequencies are so far apart you can put New Jersey between them.

There is a whole lot of radio theory and low level protocol knowledge needed for a technical answer to the question. But no, the two solutions will not interfere with each other...

In the US/Canada, zwave occupies three frequency bands:

 

908.42 Mhz / 9.6kbs -- old devices

908.40 Mhz /40kbs  -- newer device plus the legacy above

916.00 MHz/100kbs -- "gen5" devices plus two bands above

 

Even with the gen5 frequency band, there's enough separation from Insteon. There may be other RF sources of interference, though.  One never knows without a spectrum analyzer.

For good measure, don't put your dual-band PLM and your ISY an inch apart from each other!

 

By same argument, perhaps avoid Z-Wave and Insteon dual-band in the same electrical box.

 

Enough power, and little enough separation, and any signal at any frequency can theoretically saturate a receiver, as no receiver has infinite selectivity.

 

Otherwise, that's plenty of separation.

 

I'd be more concerned with what ELSE might be on closer frequencies (or same frequency) as each. 

 

- Portable phones

- wireless alarm systems

- leak detector systems (yes, my building has some kind of wireless leak detectors with proprietary system, company apparently out of business...)

- etc. etc. etc.

I have Z-Wave and Insteon devices in the same box in several locations. Both types of devices function flawlessly--each and every time. That includes program triggers as well as scenes. Echo, too.
