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.... :(
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
Thank you, Franky!
Registered here only to say that!
I disabled "Short Preamble" and "WMM Mode" in my OpenWrt and my TH16 finally connected!
Other settings looked ok:
DTIM Interval - 2
Mode - N
Width - 20MHz
RTS/CTS Threshold - off
i've seen the thread is very very old, but newest entry is only 17 days ahead.
So i've got also the problems with the Sonoff T1 (3gang UK Version) to connect to my new
Edimax RA21S Accesspoint. I had previous the Edimax 6808 V.2 which work pretty well, also with T1.
Sonoff Basic, 4CH, Wemos D1 Mini, ESP8266-1, ESP32 aso., all are working well.
Only the T1 won't connect.
I found now out why.
Its the Wifi "preamble". It can be set to "Long" or "Short"(default).
Set it to LONG and the T1 can connect.
Well some AC can't be configured this details, but if, try it.
It should be:
WPA2 mixed (sometimes only AES work?!)
DTIM Period 3 (mostly its 1 as default)
Beacon interval 100
CTS Protection disabled
and i also found (i don't realy know why this matter), but if 5GHz has the same SSID
it won't connect. Dont ask me why.
Hope that helps a bit out of a 3 year old (long) thread.
all the best
had the same issue with netgear r7000 and L1 led strip. i tried a lot of stuff including changing SSID, disabling 5ghz band, disabling nat/qos/whatever.
it must be something with a router 'cuz LED controller goes online without issues with android, iphone and even laptop hotspot
finally, the solution that worked for me:
1. disable 2.4ghz radio on router (or power-off router)
2. create wifi hotspot on smartphone with exactly same SSID and password as router's 2.4ghz network. just make sure you're not using the same smartphone for hotspot and pairing
3. pair device using different smartphone, wait until device goes online. i used compatibility mode for pairing (btw, had to disconnect led strip from controller to enable it)
4. disable hotspot and enable router 2.4ghz band
right after that i got an error on controller (blinking twice per second) but after ~5 min controller went online, and so far everything is ok
Set smart scenes to control devices by temp. & hum: working with sonoff temperature & humidity sensor (am2301, ds18b20), sonoff th10/th16 can detect the real-time temperature & humidity of the environment and set up a temperature/humidity condition to control connected home appliance, even the ones connected with other sonoff products, such as sonoff, sonoff rf, sonoff gba emulator ios
