I've ordered 3 SONOFF and tried to associate them with my eWeLink account.
One of them always appears offline and I don't know what to do to solve that.
It's necessarly a problem with this device (or my account) as the other ones work well.
This device is well detected on my local network, but the LED keep blinking twice and repeat.
Maybe it's linked to the firmware upgrade that failed before.
I can not believe ... Sonoff team!? Where are you?
Тhis is absolutely frivolous!!!
you are a school company or something else???
This is not serious!!!
My sonoff TH was working perfectly. But, since one week, keep getting offline/unavailable...
So seems many user here and there can't get there device back online. Where is the support ? Mine keep getting offline since few days. When it's about to sell there product Itead is there, but when consumer need support nobody's there !!!!
I've buy almost 10 sonoff to control my electric warmer because seems to be a good products... I worked 2/3 weeks and...then... server offline... Thx itead !!!!!
THE SOLUTION IS:
Substitude IP address of eu-disp.coolkit.cc to 188.8.131.52
Right now for some reason current eu-disp.coolkit.cc IP doesn't accept connection to 8081 port, but the old one - does. You can check it by:
telnet 184.108.40.206 8081
telnet 220.127.116.11 8081
Here is an example how to make a substitution in Mikrotik router:
Get to "IP > DNS" menu
Click on "Static"
Click on "+" (add static DNS entry)
Regexp: <leave empty>
TTL: <leave by default [1d 00:00:00]>
Click on "OK"
Close the DNS Static subwindow
Click on "Apply"
Profit! Now your POW is online!
Hope i bought only one, because it's doesn't working.
i give up
I have the same problem, Only eith Sonoff POW, I have 3 and all is offline! All my other TH10/16 basis... all is ok. Problem is only with POW. Please fix it.
I bought 3 devices (two Sonoff smart switch and Sonoff TH16). After a week,
Sonoff smart switches are ok.
Sonoff TH16 is not working now - my app Ewelink tells me that it is offline. TH16 blinks quickly twice every 1s.
Informations about Sonoff TH16:
ESP_40C883 - it is name in my router
I tried many times to reconnect device (readd) - but app Ewelink still tells it is offline.
I found in my application Ewelink that firmware in TH16 is unknown.
Sonoff TH16 is connected with my router (it gives me feedbacks - ping)
I found out that I should try to connect and try ping to this server - eu-disp.coolkit.cc - it works and gives me feedback.
