Zigbee can affect wifi

I have a bunch of Phillips Hue light strips and a couple of Go's (which I absolutely adore) so I have a Hue Bridge (Which sits on top of my Lutron Caseta bridge lol)

I have three Hue bridges and 8 APs... so far I have managed to avoid interference between wifi and zigbee but I think it's as much a matter of luck as planning. And my house is basically a series of Faraday cages.

(the APs are not all at full power)

I thought I was the only one going crazy with AP. I use 18.

3 dedicated 2.4ghz for wifi iot on channel 1, 6 and 11
2 outside 2.4ghz
3 for external dependencies (1 for each building)
4 5ghz on different channel for google stuff around the house (mainly 17 nest hub)
3 5ghz on wide channel for my wifi mesh (phone, tablets etc.)
2 for dedicated guest access (on only when there are some)
1 I constantly fiddle with

I have two outside, one in the basement, one on the third floor, and 2 on floors 1 and 2. My controller does both channel and power balancing each night. I thought the channel hopping wold affect zigbee but so far it hasn't.

Oh and I forgot 3 additional ones used by Arlos! But those will soon be decommissioned, as will all my Arlos.

All my unifi AP's are on 11, my zigbee on 20 and my hue bridge on 25

If someone asking why so many: this is what is happening when you start small and grow without planning. You buy cheap stuff and find out it is not good enough for what you add. So you buy newer one but then why not reuse the old one for a small task. Then as things grow you want maybe setup vlan. Oups! the one you bought does not support it so... I guess you know what happen. It's a circle.

I hear ya! When I bought this Victorian 6 years ago I put in a Linksys Velop meshed wifi solution, and then hung a bunch of switches off the Velops. What a disaster. I fiddled with it for a couple of years and then declared network bankruptcy. I ripped it all out, figured out where I needed access switches and APs, ran cat6A to all of it (not easy in an 1890 home), and went with a fully managed solution. Cost me a lot of money but a lot less aggrevation.

Luckily in my 1900 American 4 square we gutted it to the brick so as I was pulling wire, I pulled cat 6 to every spot I wanted an AP including one on the exterior of the house pointing to the back yard. The only other cat 6 in the house is from my office, upstairs main bath/laundry (hubitat, hue, and lutron bridge are on top of a shelf since it's central to the house) and the tv's in the house.

Not trying to get you to fix something that ain’t broke, but Zigbee channel 26 is regulated to lower power than the other channels and usually one to avoid using.

Please tell me more about this. Thought it was best to have APs on different channels. I have 3 Unifi APs all on different channels.

Same here. I use 2.4GHz channels 1, 6, and 11 with 20MHz channel width across 4 UniFi APs. I have had no Zigbee interference issues whatsoever.

Are you saying channel 26 exceed regulation on Hubitat or that it simply is using a lower power to meet the regulation?

I read that channel 25 should also be reduce in power in order to avoid bleeding into the restricted zone. Does channel 25 reduced on Hubitat?

I doubt they could get FCC approval if it did.

I’ve read that as well. Not sure since I have been using 19 and 24 for my HE hubs and 20 and 25 for Hue bridges. I’ve seen others report good luck with 25 though.

Channel 26 works great for me, so i will stick with it.

Interesting experiment. It seems edge channels are worst then center ones:

channels 22 and 23 are better than 21 and 24

Very old post from @mike.maxwell but he mentioned that many devices don't like channel 26.

Maybe this has changed in almost 5 years but wanted to through this out there.

I guess I'm lucky all my devices are fine with it :slightly_smiling_face:
