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.... :(
As some others reported pairing went o.k but the sonoff TH10 unit would not connect to the wifi, Stuart Shaw suggested a method on this page which included turning of the router security setting, i did that and my TH10 worked as it should !!.
I realised then it was a security issue I rechecked my setup of the ewelink on my android phone and found that the router wifi password on ewelink had an uppercase letter at the start(damn predictive text) whereas my wifi password is all lowercase .
I changed that password on ewelink to be all lower case and all is working , my thanks to STUART SHAW for pointing the way
I have about 15-20 Sonoff products and just recently bought some new ones. Never had a problem before... but now - definitely impossible for me to get the new ones working. Since the old ones are behind a lot of switches everywhere in the house - I feel that is not an option to try to re-configure them. The old ones are actually working very good! This is why I humbly ask for some support.
The products I am trying to get working now are Sonoff S26 and Sonoff Mini. However, I run IOS and Google Wifi.
I have tried to keep the connection to "Itead-XXX" by clicking on it as one proposed, I haven't found where to disable the security settings at the Google Wifi app. Nor at the phone. It loggs in beautiful at my wifi as usual.
But - using compatible mode, I can connect to the product, it finds it, states the brandname, then Registering for 1 sec to get to "add the room name/My device". It does not get green. Blinks green once every 2 second. Then at the Ewelink app, it states "Offline". Forever... :)
Please guide me, Gents, before I loose my mind! :-)
Yes 3.1 i've seen it.
Yes if you can connect to your iTeads you can change them. the problem has been when people have deleted them in the app whilst not connected to them. IE if their router has broken.
When you connect to an Itead for the first time, it's your phone thats talking to it direct, not your home wifi. The phone or tablet then tells the itead what wifi it should connect to. The problem for people who have changed their wifi router, is that the phone telsl the itead to connect to wifi that no longer exists. What people are not noticing is that their phone changes wifi half way through the setup process, and talks to the iteads wifi network direct. If the preferred wifi network on your phone is still the old one that no longer exists the phone will still tell the itead to connect to it. "
A quick way but not the most convenient, is to just register another email address with your ISP and then register another account with Ewelink using the new email. You have to push the pair button, but a new account will find them straight away.
I just registered another email address that i use for nothing else.
I had the same problem, tried everything. It would seem to pair, let me select the network and device name but would always end up flashing every two seconds and never connecting. I wish they just had a factory reset.
I contacted Itead three ways and just got the usual list of things to do which I'd done myself already. I suspect they just think I am using the same password. I bought a replacement and it worked first time which worked first time. My conclusion based on what I read is that if you don't delete the device from the application while it is online on the original network it will not connect to a new network properly, something remains set wrongly from the first install.
My solution - I installed using tuyaSmart which seemed to work though I didn't try it I just went right back to the eWeLink app and it paired right away.
Richard - how did you get a Sonoff device to connect with the tuyaSmart app? I though only Sonoff devices would pair with the ewelink app? I have a Sonoff 5V device with the same symptoms you were getting.
I just followed the Tuya instructions that match the compatibility pairing including the password of 12345678. I didn't actually turn it on and off just went back to the eWeLink app and it installed like new.
Solved: I've experienced this same issue. I bought two Sonoff devices and both were not connecting with my router TP-Link AD7200.
I was about to give up when I got an idea.
I took a second cellphone and I used the hot spot function to route a wi-fi network. I configured the cellphone wi-fi with the same SSID as my tp-link router.
I disabled the main router and enabled the cellphone. I could pair quickly using the compatible pairing mode with the cellphone.
Then, I turned the Sonoff off, disabled the cellphone wi-fi routing and enabled my tp-link router.
As the SSID and password were the same, it connected and worked!
i had the same issue , today i have the breakthrough , just not use special characters in the password just user numbers and alphabets . my all devices are sync now
