This is interesting as I get a number of devices that are Zigbee and they fail to receive their command.
My ST hub is very close to my router, so thinking this may be the cause of these failed commands.
What distance would you recommend between my ST hub and my router?
Not sure about the band overlap with wifi…have to confirm what frequencies they are on.
Easy to shift the Hub mind…might give that a whirl and report back.
Unless anyone knows otherwise, Zigbee in the EU (as I’m in UK) is 868MHz, so way out of Wifi 2.4Ghz or 5Ghz.
Although Zigbee in other countries does use the 2.4Ghz band!
As a network engineer and former field tech, I’d like to see the names and quotations for those experts. Because I’ve never seen it debunked, and I stay pretty up to date on the technical literature in this area.
There are some zigbee device manufacturers who say you are not likely to run into trouble, but that’s hardly the same thing as debunking it.
All the field techs so I know follow standard industry guidelines for deployment to avoid the interference problems. And there have been plenty of studies which published the numerical measurable effects of distance and interference.
If you’re saying that anecdotally there are lots of people who put a Wi-Fi router right next to a zigbee hub and still have an acceptable quality of service, sure. Everything depends on the exact local conditions, including the directions the antennas are pointing since even though these are Omnidirectional signals, they do spread as they move out from the point of origin. And whatever objects are around that might cause bounce back.
Will those same people probably have even better performance if they separated the two transmitters? Likely yes, but not better enough that people living in the house would necessarily notice.
There’s no harm in trying it one way, and if the results are acceptable to you, then just not worrying about it. But that’s not the same thing as “debunking” a practice based on a measurable physical event.
Sorry to go off topic on this.
Thanks for all advice…from the input I’ve had, it does like Zigbee could be using 2.4Ghz even in the EU (and UK) but could also be using 868Mhz…too many conflicting information sources!
It may be that this is dependent on the device implementation by the manufacturer.
Either way, I did have a look at moving my ST hub but that is more a weekend job along with digging out some PowerLine adaptors to link the ST hub to the router.
I’m unfortunately in a particularly wireless unfriendly house with potentially multiple double skin brick walls between hub and device. The Zigbee mesh may help sometimes but fear sometimes this has it’s limitations.
