Oliver, I followed the link in your post and checked out the Neo online. They actually show two different versions of PIR sensors. What is funny to me is both sensors look very much like the fibaro and dome sensors which themselves also look very similar to one another.
I had noticed the Fibaro and the Dome look very similar. The biggest difference is the Dome has a magnet mount in the back which attaches to a swivel and the Fibaro instead offers a small plastic clip. The LED is different and the case is slightly different but I had wondered if they perhaps were made by the same manufacturer. Rebranding these devices seems common. What is odd is the two models sold by Neo, one closely resembles the Fibaro with a clip mount and the other resembles the Dome with the magnetic mount
How does your Neo motion sensor work?

Does this device require I have the “Hue Hub” to make it work… or if I install the Hue Binding into my openHAB2… it will work without the HUB?
Thanks! Dave

Well…another big issue I realize… the Hue system is ZigBee-based… and this will directly interfere with normal 2.4Ghz WiFi. Yikes. I have Ubiquiti Unifi WiFi Access Points throughout my house… and if I add any ZibBee stuff… they will directly interfere with my WiFi.

WiFi’s three non-overlapping channels (1, 6, and 11) use the exact same frequencies as ZigBee channels 11-22. I’ve now read that ZigBee channel 26 is usually relatively unaffected by WiFi, but many ZigBee devices do not support it.

Can you specifically select the frequency (ie Channel 26) to be used by these ZigBee Hue sensors?

I’m not sure I want to get into the issues of my WiFi not working or the Hue stuff not working reliably… Hmm.

What is the experience out in openHAB land of mixing ZigBee and WiFi???

thanks
Dave

Definitely an interference issue when installing ZigBee in a standard 802.11n (2.4 Ghz) environment. Hmmm. I think it will be only safe if I can force ZigBee Channel 26 to be used.

I use the Hue binding with a Hue bridge and hue bulbs, dimmer remote and motion sensor. I also have a zigbee dongle and several other zigbee devices. I also have lot of WiFi connections, laptop, Lifx bulbs (which run on wifi) WiFi plugs ect. and no interference problems.

That’s wonderful, Andrew. Do you know what WiFi channels your Access Points or WiFi Router is using?

Maybe in your situation you are not using all the WiFi bandwidth… and your ZigBee devices are using open frequencies… which would be great.

I know in my setup, I am using WiFi channels 1, 6, 11 for my 3 Access Points, which provide excellent WiFi coverage throughout. I am very hesitant to disable one of the channels and have to go to something like this:


So I am curious about how others make ZigBee work properly/reliably with WiFi.
Thanks for your reply.

Just wanted to check back in and say that it seems my sensors do report battery state after all, because I finally had some completely stop responding and when I replaced the battery they reported 100% again. The problem seems to be that their scale must be nowhere near correct because my sensors worked for months at “0%” (so long that I thought the channel was just broken) before they actually died. I think that may explain some of the reviews reporting poor battery life too, because if you’re going strictly by the reported battery percentage you only get a few months out of them but mine lasted well over 6 months of regular use as presence detection and what I feel is fairly aggressive temperature/light logging set at reporting at 3 degree (down from the default of 10) and 5%(? not sure what their percent translates to - but down from the default of 10) changes.

I saw several folks report same on amazon, I think voltage range is wacked
