Shelly 2.5 not working

    • Autor

    Hello all.

    I have several shelly's 2.5 and two of them have stopped working recently. After turning on the 230V, they make a buzzing noise and are not visible, sometimes the indicator light will flash. I made flash and re-uploaded the original software with tasmotizer. They appeared as AP and I connected to them, but only when they are connected to the 3.3v module. Connecting to 230v gives the effect as described above. Maybe some of you met with such a case, any suggestions?

    There are rumours that the (3) electrolyte condensers in Shelly 2.5 are damaged by high temperatures over long time. Hence, the primary step down converter doesn’t work properly. This leads to the outlined issue, especially to the strange sound effects. Skilled people could replace the faulty condensers…
