    Shelly plus 1 dead, does not switch

    Anyone got any Shelly remote devices around here?
    I’ve got a few of these and they were all working fine for about a year. Today I noticed that one of them that controls a single light switch isn’t working at all. I mean it’s so dead, even the light switch doesn’t control the relay. No clicking, no anything whatsoever. Unfortunately it’s in the basement in a dark room and trying to get it out is going to be interesting. Maybe there is some carnage in there, who knows. It was hooked up to power mains.

    The other exact same one is in the same room, like 5 feet tops away controlling an air exchanger on a different AC circuit, but it’s powered through a low voltage adapter survived just fine! Weird.

    If it was weather / power related, nothing else died in the house.

    Gonna be interesting looking inside and see what happend and how it works.

    older units have a buck convertor with a shit electrolytic or 2.
    didnt you open any before fitting?
    i often recap brand new stuff so it wont fail later!

      Here is the carnage and the fix.

      Problem was that the phase and neutral had cold solder joints!
      Resoldered all of them and my Shelly is working once more!

      Mine have two 400V caps fitted. I measured around couldn't find anything else wrong, so I fitted a wire with a plug, plugged it in and this Shelly popped up again in my app. I can control it, so all is good.

        Is there vibration on the controller because the only time I see it that bad is when the hole unit vibration or the terminal pins heat up and cool down many times and over a period of time you see this or just shite soldiering joints to begin with

          Nope, no vibrations. It sits inside the box for the light switch. It barely fits in our North American boxes. They are smaller than the European ones.

            one of the relay cotacts is cracked too - looks like maybe a production problem or they took a beating in transit

              Sooo.... I put the repaired Shelly plus 1 back into the light switch and works A1 again.

              I had to look again at the pics and sure enough, it looks like one crack at the relay. I put the Shelly back under the microscope and it was fine.
              These Shelly's are pretty nicely packaged in their boxes. One would think that should be good enough. A production problem? Maybe... It worked good for almost a year.
              Our electrical boxes in NA are smaller than the European ones. So jamming a Shelly behind a light switch with all the wires is an art!

                I googled this device and found out that have some interesting devices I might buy a couple of them to control some things in my new shed

                But if buy them I will definitely be taking it apart to see if there are any soldering joint issues before using them

                  That’s the reason I got it. Making things controllable that weren’t. Got my 20 year old air exchange on a schedule since about close to a year now. Works perfect. I wanted to do more too, but haven’t got the time to mess around and make more things controllable. Haven’t even finished my new work room in the basement. Oh well…

                    Hello, i bought dead nintendo switch oled.
                    after plugging charger with amp meter device shows 5v and 0,0 or 0,02 amperage draw.
                    I inspected motherboard and someone tried to reflow or replace m92t36 and didn't do it well, i resoldered it proper and find that usb-c fuse was blown too(replaced it).
                    After this device started to draw 15v and something around 0,48 but only for few seconds after this returned to 0A draw.
                    I tried to plug motherboard without battery - shows 15 0A and when charger was pluged i put battery back in then console started to charging battery but stuck...

                    Micro Momentary Push Switch?
                    by Natob82
                    Great to be here! I'm a newbie here trying to find a "micro", momentary push switch to repair a Sony "clamshell" video walkman. This micro switch has long since discontinued by Sony, however I hope there are third-party switches of the same size and functionality that I might be able to source to play the same role. The purpose of this switch is to tell the video walkman that the user has activated the mechanical tape eject button, turning that physical action into an electronic signal that tells the tape transport mechanism to open so one can load or eject a video tape. I...

                    NEC TurboExpress On/Off Power Switch Replacement Help
                    by grimacelord
                    Hello,

                    I've been working on a NEC TurboExpress and I accidentally got the plastic inside the power ON/OFF switch too hot while doing other repairs and melted it. At first, it would still power on when sliding the switch, but you had to really press inward while sliding to get it to work.

                    I removed the switch component and tried to gently melt the plastic back so it would work more reliably and all I managed to do was make it worse.

                    I need to find a replacement On/OFF switch for this, but having some trouble figuring out which kind of switch I need....

                    Help making a switch work the opposite way with a relay
                    by SluggerB
                    I have a very small float switch, I'm using in a very small tank. It only fits in one way. Link https://www.amazon.com/uxcell-Switch.../dp/B07DZ1J2GB

                    I want the switch to be open when the water is high, and closed when the water is low. Unfortunately it works the opposite. And since this switch is designed to be underwater, it's all sealed up, there is no taking it apart or hacking it up.

                    It will be driving a water pump, basic idea, when the water is low, switch closes, which turns on water pump, when enough water is in the tank, float switch floats,...
