FAQ
TL;DR: 10M+ installs confirm eWeLink’s scale [eWeLink – Smart Home — Google Play]. "Maybe updating the app will help something?" [Elektroda, Gienek, post #20096084] Update the app, then log in; outdated versions caused repeated “wrong login/password” loops [Elektroda, Gienek, #20096117; wlopata, #20100046].
Why it matters: This FAQ helps eWeLink + Sonoff Basic users fix sudden login failures without re-pairing devices.
Quick Facts
- Typical eWeLink app version noted as resolving issues: v4.23.0 (July 2022) [Elektroda, Gienek, post #20096117]
- Affected user was on v3.14.1; updating restored access immediately [Elektroda, wlopata, #20096142; #20100046].
- Sonoff Basic uses 2.4 GHz Wi‑Fi (802.11 b/g/n), not 5 GHz — plan router settings accordingly (“SONOFF BASICR2 — Product Page”).
- eWeLink requires Android 5.0+ on Google Play (“eWeLink – Smart Home — Google Play”).
- Devices are cloud-bound to your account; reinstalling the app does not unpair devices (“eWeLink Help Center — Device Binding”).
How do I fix eWeLink saying “wrong login” even when my password is right?
Update the eWeLink app from the Google Play Store, then log in again. An outdated app (e.g., 3.14.1) triggered persistent “wrong login” prompts; updating resolved it instantly [Elektroda, wlopata, #20096142; #20100046]. A helper explicitly advised updating to v4.23.0 [Elektroda, Gienek, post #20096117]
What’s the fastest 3-step fix for the eWeLink login loop?
- Open Google Play > search “eWeLink – Smart Home” > tap Update.
- Open eWeLink > enter the same email and password.
- Confirm your devices appear.
This worked end-to-end for the thread author after the app offered UPDATE [Elektroda, wlopata, #20100046; #20100187].
Will updating or reinstalling eWeLink force me to re-pair my Sonoff Basic?
No. Devices remain bound to your cloud account. Reinstalling or updating the app does not unpair devices. Log back in with the same account and your devices reappear (“eWeLink Help Center — Device Binding”). The thread author updated and immediately reconnected without re-pairing [Elektroda, wlopata, post #20100046]
How can I confirm my login details are correct before I change anything?
Install eWeLink on a second smartphone and try the same email and password. This isolates credential errors from app version issues [Elektroda, Gienek, post #20096117] If it logs in on the second phone, update or reinstall the first phone’s app.
What version should I be on to avoid the “wrong login” glitch?
Check your installed version in Android Settings > Apps > eWeLink. A helper referenced v4.23.0 as current in July 2022; the failing device ran 3.14.1 [Elektroda, Gienek, #20096117; wlopata, #20096142]. Update via the store for stability [Elektroda, wlopata, post #20100046]
Could my router or Wi‑Fi cause eWeLink login failures?
Login failures in this case were app-related, not router-related [Elektroda, wlopata, post #20100046] Sonoff Basic requires 2.4 GHz; ensure your SSID is 2.4 GHz and enabled. 5 GHz-only networks won’t work (“SONOFF BASICR2 — Product Page”).
Why does eWeLink show only “wrong login” instead of “wrong login or password”?
Message wording can differ between app versions. One user saw generic errors, another always saw “wrong login” until updating [Elektroda, Gienek, #20096084; wlopata, #20095415]. Update the app to align with current error handling [Elektroda, Gienek, post #20096117]
How do I reset my eWeLink password safely?
Use “Forgot password” on the login screen, then follow the email link to set a new password (“eWeLink Help Center — Login & Password”). After reset, log in again. If you still loop, update the app first [Elektroda, Gienek, post #20096117]
Edge case: I updated but still can’t log in. What else should I check?
Check you’re using the correct account region/country and email. Region mismatches or changed emails can block logins (“eWeLink Help Center — Change Region”). If you hit rate limits, wait and try again (“eWeLink Help Center — Login & Password”).
Does clearing cache/data help with persistent eWeLink errors?
Yes. On Android: Settings > Apps > eWeLink > Storage > Clear cache (then data if needed). Reopen and log in. This resolves many app-state issues (“Android Help — Clear cache & data”). Update the app afterward for best results [Elektroda, Gienek, post #20096117]
How do I know if Sonoff Basic is still online after I regain access?
Open eWeLink and check device status. If offline, verify the device is powered and on 2.4 GHz Wi‑Fi. Use your router’s client list to see if it’s connected (“eWeLink Help Center — Device Offline”; “SONOFF BASICR2 — Product Page”).
If pairing fails after login, what’s a safe next step?
Use the official pairing method in the device manual. Typical: press and hold the button to enter pairing mode, then add in eWeLink (“SONOFF BASICR2 — Product Page”). Ensure your phone is on 2.4 GHz Wi‑Fi.
Is there any proof that updating actually fixes this?
Yes. The thread author reported success immediately after tapping UPDATE in Google Play, then logging in with the same credentials [Elektroda, wlopata, post #20100046] As one helper put it: “Maybe updating the app will help something?” [Elektroda, Gienek, post #20096084]
How widespread is eWeLink, and does that affect reliability?
The app shows 10M+ installs on Google Play, indicating broad deployment and active maintenance (“eWeLink – Smart Home — Google Play”). Keeping to current releases reduces edge-case login bugs [Elektroda, Gienek, post #20096117]
Will switching phones break my setup?
No. Your devices bind to your eWeLink account in the cloud, not the phone. Install the app on the new phone and log in with the same account (“eWeLink Help Center — Device Binding”).
