Orbi RBR40 w/ 2 sats. My z-wave hue lights are always going unresponsive please God someone help me!
I am offering $1k USD to anyone who can help me. To be certain that statement is a JK but if someone could actually help me I might actually do it lol. I am pretty tech savy and have been PLAGUED by ...
I really appreciate the input Crimp.
To me your theory is the most plausible as it explains clearly how I could intermittently lose 5-8 lights out of the clear blue and in the absence of any obvious cause. If my Orbi router, which is set to 'auto' channel selection for 2.4ghz wifi, decides to switch itself and the (2) sats, for whatever reason, understanding the documeted interference between zigbee and 2.4ghz wifi, this could explain the dropping lights.
On the Amazon Echo Plus support forum, a user nice enough to try to help me holds a different theory and subsequent thoughts regarding how to fix:
'No, zwave and zigbee are low power wireless mesh networks. It's very rare that wifi will interfere.
As I mentioned, you have a zigbee network and need to strengthen your zigbee mesh. If you strategically place zigbee smart plugs throughout your home, it will create a robust zigbee mesh network and your bulbs will stabilize.'
So, I've got a couple suggestions, but to me Crimp, yours sounds closer.
Figuring the i. Echo Plus can not deactivate its zigbee signal & ii.it does not allow one to change zigbee channel:
Should I start by forcing Orbi to a specific 2.4 wifi channel and see how it goes for awhile? What channel should I use for Orbi?
That advice is straight out of the Zigbee instructions. Unlike what the industry calls "mesh" in terms of WiFi systems (which is actually a master/slave relationship), it appears that Zigbee is a true "mesh" where each of the devices communicates with devices near it. If there is a gap in the mesh, communication is more difficult so the recommendation is to have Zigbee devices in lots of places.
Despite more searches, I cannot find any information on Amazon Echo Plus Zigbee channels. This post seems to indicate that the Philips hub is able to define which channel to use:
https://www.reddit.com/r/tradfri/comments/9mnlwr/changing_zigbee_channel_due_to_interference/
This is where my total lack of hands on experience with Zigbee is frustrating. My sense of it is that Zigbee devices will follow the hub to a new channel unless they have to be paired again.
So there are now two criteria for selecting which 2.4G WiFi channel to use:
- To avoid interference from all the neighbor WiFi systems, select a channel that is not dominated by neighbors' WiFi systems.
- Then set the Philips hub to a Zigbee channel that does not overlap with the Orbi WiFi.
Note the comment by JDRoberts in this post:

The context of that post regards Samsung Smart Things hubs which cannot be changed once they leave the factory, but the principle remains the same. If Orbi WiFi is set to any channel from 1-6, then set the Zigbee to the high end. If Orbi is set to any channel from 6-11 (North America. to 13 in the rest of the world), then set Zigbee to the loweest channel.
This is all good information Crimp thank you.To your point, I have not been able to locate any info in terms of what zigbee chanel echo plus uses or whether or not it is a static channel or can vary. Whereas the hue bridge allows one to establish a specific, static zigbee channel to use, the Echo Plus does not (atleast I am not aware of an option to accomplish this).
Understanding that your theory relates to Orbi auto switching 2.4ghz channels, thereby causing sudden zigbee overlap/interference and subsequent lights failing, all at once:
Is there a way to identify which 2.4Ghz channel Orbi is currently using while set to 'auto'? Does it make sense to track this channel from time to time and certainly after a light failure to see if I can identify the channel that is screwing up the program?
Or just buy a few zigbee repeaters? But this option seems like a bit of a bandaid IMO...

The Zigbee devices themselves should create enough of a 'web' to communicate (once they are scattered all over the house).
There are any number of WiFi tools that will display the channel of every WiFi access point they can find.
For Android, I typically use the WiFi Analyzer App by Kevin Yuan. (There must be a dozen similar apps.)
On Windows, I like WiFiInfoView from nirsoft, one from Lizard Systems, and one from Matthafner.com
Most of these have settings to avoid showing all of the nearby WiFi systems, such as restricting to certain channels, certain power levels, etc.
Did that Philips Hue hub show up?
Yep the hub showed up. Its sitting in the kitchen on the counter lol. Lights are working perfectly and I'm trying not to open the damn hub lol
The hub should be a win compared to the Echo Plus's as it allows for establishing a particular zigbee channel to use. My hesitation (and I apologize as it is increasingly off topic) is the integration of the hub with Alexa voice commands. Reading the poor reviews of the skill required to link the hub with Echo voice commands gives me pause...
For now I'm going to check the network analyzer tools you suggested - thank you for those. When (it will happen) the lights fail again I'll see if I can identify a switch in channel that may have caused it. If so I plan to force Orbi to a specific 2.4ghz channel that doesn't cause problems with zigbee. If I cannot ientify any problem with channels I plan to break open the Hue hub or purchase a few zigbee repeaters.
does this sound lke a reasonable approach in your mind?
