After Successful pairing and Renaming the device it does not connect to wifi and Green light keeps blinking, tried to delete and repair but no luck.
One device is connecting and another - Does not.... :(
Even for use in USA I would have opted for an EU version since it works down to 90 V. And on top of that you get a whole extra range of input voltage protection.
Hi, this very very long tread reports from hundreds or maybe thousands of users, having trouble connecting Sonoof devices to (mainly) newer routers and or new networks. I went through all suggestions and ideas and tried it on my new TP-link AX 50 wifi 6 Router, with an updated TH 10 from Sonoff.
I ended up spending nearly 5 (five) hours testing all kinds of suggestions from here. Nothing worked.
My conclusion is that the TH10 from Sonoff is not designed to work with newer devices and modern WiFi. Some users report that some Sonoof devices might work, while others do not - from the same batch (where users might have bought several devices at the same time). That seems to be some quality issue with the devices.
Besides, as most new routers are capable of utilizing both 2,4 and 5 GHz, it seems stubborn that Sonoff keeps focusing on only one of these (2,4) and not making it possible for the Sonoff devices to at least negotiate with devices that have both turned on, as that is what most users will do today. Or at least have the Sonoff device acknowledge the existence of WiFi with both bands turned on, and then try to connect to the 2,4 GHz part of the router. I’m not a WiFi engineer, but think that it might be possible to do!
Evidence: I have myself installed a WiFi device (from Panasonic - see image) on a Panasonic heater pump to allow for remote WiFi-linked control. And that device did connect nicely and smoothly to the very same TP-LInk router, that the Sonoff device refused to connect to.
Anyhow, I have taken off my Sonoff TH and will give it away for someone else to experiment with, and I am buying an (EU) alternative, which has more options - and is a little bit pricier.
i solved using a tplink wifi extender, in order to create a new separate network. Ho risolto problemi di connessione dl sonoff 4ch pro r2 usando un ripetitore tplink, per creare una rete separata
I have the same problem, except the unit is now 2 hours away
Sonoff Basic... same problem after pairing cannot connect to wifi...
My solution was create new wifi with name "test" and without password... then all works correctly (my firmware was very old 2.6.0) so then I updated my SONOFF to 3.5.0.
Then I remove device from app... and again add it by standard way to my standard wifi with password.
Probably problem was in SPACE character in WIFI name or something with security standard...who know... :)
Now all works correctly
Hello Christopher Denye!
Did the TH16 went off by itself?
Any changes made or devices added on your Network lately?
Have you tried your defective TH16 on another network?
Any other sonoff devices on your actual network? are they working fine ?
Let me know if I can help !
I have a TH16 been in use for a couple of years. Went offline yesterday.
Spent the last 4 hours trying to repair it. Had to pour me a large glass of scotch!!
Tried every option, AP, simple pairing, 5Ghz off, reboot routers. (AP mode access denied with 12345678).
Tried that on 3 different routers.
Various options in the routers, security, channels, etc etc
Run out of options other than buying a new one.
Possibly the wifi module is broken.
Referring to my comment of 9 days ago, I took the device back to the old router, having WEB security for the Wifi. Again pairing and connection maintained without a problem. I think, the POW R1 can't use modern Wifi....
Hi every, I had the same problem. My first box have died with time, so my operator launch a new one, exactly the same.
At this point, all my devieces in Ewelink app was "Not connected".
I succeed to connect a new deviece, it was recognized, but the statut when i want to use it was "Not connected".
To solve this problem, I basicly rename my Wifi network , and reconect each deveice one by one. I don't understand exactly what was the problem, but this solution work to me.
I hope that can help you
