rafarataneneces Posted August 29, 2016 Posted August 29, 2016 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!
G W Posted August 29, 2016 Posted August 29, 2016 Insteon is actually 914.975MHz. The two frequencies are so far apart you can put New Jersey between them. Best regards, Gary Funk
MWareman Posted August 29, 2016 Posted August 29, 2016 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...
vjk Posted August 29, 2016 Posted August 29, 2016 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.
jtara92101 Posted August 29, 2016 Posted August 29, 2016 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.
