#51 Sonoff Problem Resolved | Low / No Connectivity | Frequent Offline or Disconnections | vccground

[@orhanyor]

had the same problem no power no light no nothing. Injected 3.3v from the serial port and it started to work. Replaced the capacitor like you did and it solved the problem thank you for the video!

[@the_vccground]

Wow ! Great. It means the power supply is dead, but the next circuit is okay.

[@orhanyor]

@@the_vccground 5V input was fluctuating and thus the 3.3V rail was not stable. I just replaced the cap thanks to your tip and it works fine now.

[@kooscoolen4543]

I bought 3 of them years ago. One has never been used and shows the same issue as yours. Thanks a lot for your hint. I'm surely gone try it. Regards from Finland.

[@the_vccground]

It's my pleasure brother ❤️👍

[@JanPieterDuhen]

I tried your modification and indeed it worked, but after a month or so, I got the same connection problems as before. What worked for me until today is to program the sonoff basic with de tasmota-light version (not het minimal-version!). It seems all the extra stuff that is in the standard-tasmota version, makes the ESP8266 draw more power while attempting to connect via WiFi. With the aging power-supply not up to this task, the connection problems start showing. Using the trimmed down tasmota-light version, I have no more connection-issues with the older sonoff basic units. Hopes this helps anyone struggling with this issue.

[@the_vccground]

Thank you brother for your valuable input. I'll check this fact to make sure it works that way too ❤️👍

[@mirceamarinache7038]

Thanks very much. Using your information about sonoff breaker WiFi I was able to solve the problem even wasn't the same model. Thanks.

[@the_vccground]

Glad to hear ❤️👍

May I know what model do you have?

Thanks It's work for my sonoff Elco 10v 1000uf and ceramic 104

[@squalazzo]

i had same problem recently, i'll try this trick, thanks!

[@the_vccground]

Definitely, try it and share your experience. ❤️👍

[@sjude68]

I have a Sonoff basic. I was using esphome on it. But yesterday I flashed Tasmota. After that wifi is not connecting. In your video you replaced capacitor to 1000mf and also added 104 ceramic. Should I just replace capacitor or add the 104cap. Because after adding 104 wifi was still not connecting.

Greetings vccground - Great Content!!! Can I power the Sonoff Basic R2 with 12V DC battery as is or would I have to remove that capacitor and connect at those terminals as shown in your video or other method? Also would the draw on the 12v battery be low? Thanks ...🙂

[@the_vccground]

It won't work as is. Connect directly at both capacitor legs. No need to remove capacitor if it is of 16v or higher ratings.

[@dmrspec4750]

@@the_vccground - Thanks for quick reply, please confirm it would work with 12v DC battery, also since DC which would be positive and negative on capacitor legs... Your Reply is Greatly Appreciated 🙂

[@the_vccground]

@@dmrspec4750 Yes, it will work fine with a 12V battery. Connect battery positive to Capacitor positive and battery negative to Capacitor negative terminal 👍

Excellent video. I have same problem with Sonoff TH16 and would like to know where to add capacitors on the board. Thanks.

​@@the_vccgroundhai bro,what to do if totally die no power at all

[@the_vccground]

@@rizalkuruvi Need to check it's power supply than. If you don't have experience in power electronics, I don't recommend you to try to repair the power supply as there are dangerous voltages present in that area.

[@the_vccground]

@@rizalkuruvi Alternatively, you can use a 5V mobile phone charger or any external 5V power source to power your Sonoff. If you feel worth & are located within India, you may also send it to us for repairs. OR feel free to join & post some pictures of your Sonoff switch to 'vccground' telegram channel. I'll try to guide you in repairs.

Both look similar. You can go with anyone. I had also done a video on this 3 years ago. You can watch it here kzbin.info/www/bejne/gWrMn4N3hK2GorMsi=4LRv9dr8JYuwCuyv

@@the_vccground - Thanks So Much!!!

[@MrBobWareham]

Very good but I would have used a 16 volt cap longer life as it could be on 24-7 but liked the video.

[@the_vccground]

Yes, that too would be absolutely fine 👍

[@FabioNatalucci]

why you doesn't use the same values of capacitor of original one? v10, 1000 uF ?

[@the_vccground]

Because I didn't have the same value available with me at that time. Hence used 1000uf instead of 470uf. It is acceptable.

[@mohamedmalkhaan4111]

Can we power up by 5V then sonoff device's

[@the_vccground]

Yes, you can power Sonoff with any voltage between 12v to 5V DC.

I haven't used any Tasmota app in this video, it's Tasmota's own web UI. If you still need an app to control Tasmota devices, you can get "Tasmotrol" from apple store, or "Tasmota Remote" from Google Play store. Watch video #42 on this channel for detailed explanation.

Check the voltage at terminals/test points named VCC and Gnd. If getting 3.3v, then check the LED with multimeter. If not getting 3.3v, the problem is with the power section...
