Connecting Sonoff switches to a mesh network

Im currently using the Engenius EMR3000 kit mesh router and i am unable to connect the switches to be paired to the app. Anyone knows how i can do it? Can switches even be connected to Mesh Routers? I have attached a picture of my Wifi settings.

I finally was able to connect mine after failing numerous times. I cleared cache and data on my ewelink app, switched the deco router to just 2.4g and the rebooted the router and it finally paired and connected successfully. Hope this helps someone else too.
I have the orbi rbk23 mesh system and I couldn't connect at the start due to selecting 5g by default. I went into the advanced wifi setting and turned off 5g signal and was connected easily as 2.4 was only available. I turned on the 5g again and the sonoff switch is working just as it should.
The problema seems to be 2,4 GHz network can have band of 20ghz or 40 GHz and often the routers no mesh have 20/40 auto selection. SONOFF Is going to 20 without possibility to change and mesh routers Is fixed to 40 for bandwidth issues....
I had the same issues connecting to a Tenda Nova MW6 mesh network. Tried to select a 2.4ghz channel using wifi analyzer but it just would not switch from the 5ghz channel. Then I had a brainwave! Dug out a very old Sansung phone, installed eWelink and could connect to 2.4ghz no problem! The Samsung phone did support 5ghz but seemed to prefer 2.4ghz for some reason so problem solved.

I have some of my sonoffs connected to a wirelessly uplinked unifi accesspoint which is as close to a mesh as I am prepared to go, and they seem to work just fine.

Remark: I don't need to turn off any Deco M5 unit during mentioned pairing mode...

Helo everybody! I purchased one TP-Link Deco M5 3 weeks ago (March 28th). After easy installation of TP-Link Deco M5 (kit with 3 pcs) I faced problems with sonoff Touch switch (I have 2 in my home - 1 gang). I also have 2 sonoff dual wifi switches but in these switches I doesn't have any problem when I changed for deco m5 mesh wifi. I only solved this issue in the sonoff touch switch pairing again the both wifi switches using one old cellphone (android samsung) that only use 2,5GHz band for wifi connection. With this cellphone I don't have any problem and then the switches worked immediately (after normal pairing process = pull the setup buttom for almost 7 seconds and then start paring mode). I hope that these information will help you!

I am simply using the Basic and Dual.  BTW, did you see my new thread about using the Dual with a ceiling fan and light?


That's interesting, what Sonoff devices are you using as 1 of my 4 channel switches absolutely refuses to connect to anything other than the original AP it was setup with.
Here's what I did as a work around. I am using a Samsung Connect mesh. Sometimes the itead device during pairing thinks the network is 5 ghz.  So, I cheat. I set this up one time and just cycle through the following to get the sonoff on wifi.  I have an old TP-Link router. I configured it to only run on 2.4. I shut my Samsung mesh net down and connect the TP-Link to the router and bring it up. The wifi password is the same between the two routers. I use the TP-Link net to connect the Sonoff to wifi, and shut the Sonoff off and back on. Once I know its connecting, I shut the TP-Link down and bring the Samsung back up. The Sonoff doesn't know its a different network because the SSID and wifi password is the same, and it ignores the 5 ghz, and connects at 2.4.  Doesn't fail.

Thank you, Jon.  Let me see what the app looks like on Android and maybe I can find a similar one for iOS.  

Have a great day ahead!

Yes I'm on android, I assume there is an equivalent for iPhone you'll have to investigate I have no experience with apple

Hi Jon,

Thanks again for responding.

I take it this app is on Android?  I can't seem to find "WiFi Analyser" or "WiFi Analyzer" on the iTunes store.

Please advise . Thank you.

That's fine, mine are setup in AP mode as well.

I have "WiFi Analyser" app installed and that tells you what network your on.

Thank you for responding so quickly, Jon!

To answer your question, yes - the Sonoff's are in the same house.  But how do I determine if it is on the 2.4GHz or 5GHz band?  There isn't a way for me to switch this either on my iOS' wifi settings or on the M5's app.  

Thing is, I have set the M5 to "access point" mode as I could not use it in "router mode".  In router mode, I'd need to have all my wifi devices on a different subnet.  

I figured this might be a 2.4GHz / 5GHz issue but not sure how I can "force" the mobile device used to pair the T2 Sonoff via the 2.4GHz band.

Any additional advice you should share would be most appreciated.  Thanks again, Jon!
