I know we’ve all seen and seen various discussions about zigbee being unstable due to sharing of the 2.4 spectrum on this forum. However, how true is this?
Control 4 seem to do okay. Philips seems to be pretty robust albeit it uses ZLL. My Heatmisers, though floors apart seem rock solid. According to the zigbee alliance: http://www.zigbee.org/zigbee-for-developers/applicationstandards/zigbeehomeautomation/
Other devices operate in the 2.4 GHZ band, will they cause any problems for ZigBee Home Automation products?
ZigBee is very robust and has demonstrated superb tolerance to extreme interference. The Las Vegas Convention Center is one of worst places for wireless devices, especially during the annual Consumer Electronics Show. Interference at that show often impedes many cell phones and Bluetooth headsets from operating correctly. ZigBee has always performed flawlessly in these extreme environments. For more details, please see the results of extensive coexistence research in the white papers section of the ZigBee website.
Does ZigBee Home Automation coexist with Wi-Fi?
Yes. All ZigBee standards and Wi-Fi are designed to operate effectively in the same environment. ZigBee takes full advantage of IEEE 802.15.4 proven interference avoidance techniques and features a unique channel agility mechanism. In fact, there are products in the market that have both ZigBee and Wi-Fi in them and work very effectively in buildings and homes.
So is the instability actually just a Smartthings issue and nothing to do with Zigbee? Even though according to the above I do not need to I have now moved everything else away from the channel used by my v2 hub (thanks to @Fuzzyligic @JDRoberts for the info) I’m still needing to re-seating batteries in random devices in the home and to be honest getting pretty fed up of doing it. I’ve now got more than 50 Zigbee devices and repeaters in the house and to be honest every other day one device or another is “stuck”. My zwave devices are faring much better.
Are ST looking into improving this aspect?
There are lots of things they could do to help, eg. include signal strength and quality meters in settings for every device appearing in the app.
I’ve got to the point that I feel like I am a servant to smartthings rather than the other way around!!
