hello, thanks for little tutorial, I'm adding a template: {"NAME":"S60","GPIO":[1,1,1,1,224,544,1,3104,1,32,1,0,0,0,0,0,0,0,1,1,1,1],"FLAG":0,"BASE":1} few details: |

Hi, is there any chance you could make a video of how you disassembled it?, thanks. |

Good work! I'd suggest creating a device template in https://templates.blakadder.com/ where you can also post about the difficulties of how to flash the device. |

Thanks everyone for this guide. It worked, the template was also very useful for configuring tasmota. Opening the plug was quite easy using a knife and pulling. Then unsoldering the ground pin was also possible, but unsoldering L and N was a real nightmare. With the help of low solder temp and flux and solder wick I finally got it done. I don't think I would do it again unless there is an easier way. I wouldn't recommend this to anyone else, I found it very difficult. Isn't flashing over the air an option here? Update: 11-7 |

firmware is only tasmota32c3.bin to use- which is only english. |

i needed no soldering, i just got some flexible piece of metal from smail chinese wire grips and bended the end in s shape. i slide it on the side of the card, it requires multiple tries to get it correctly (basically i launch the flashing command in a continuous loop then try to place the jig correctly. i tap 5v and gnd from other accessible places on the pcb.

…Yes, although I don't need that feature, it might come handy.
@ouinouin can you please take a couple pictures of that printed jig and how you use it for flashing? Also, from where you take 5V and GND? I just recently managed to open that file with FreeCAD and seems like it should be way easier to do it this way, if it doesn't involve (much, if any) soldering.

The original post describes a good approach, and it doesn't seem to be wise to stray far from that path, at least not as long as there isn't a better description utilizing a jig that avoids L+N soldering. Heating and pulling at the same time wasn't working out well initially, so I went for the alternative option mentioned here of using a solder wick. It was a big mistake, a ton of solder ends up being on the other side, and at one point there will be no solder on the top to assist with heat distribution, so after a lot of pointless struggling, I ended up adding some solder back. Still, the largest mistake was seeing all the helpful info here and figuring that if there's a way (with a beaten path at that), I'll supply the will. Thanks for everyone for all the helpful information though. If only the manufacturer would have just a fraction of this good will. |

I found an alternative solution: cut out a window and then glue it back together. There should also GND point be available in that Windows. |

@tykasan NEVER again NEVER add anything to power metering sockets. There is by design AC mains level at the GPIOs. |

@tykasan Have a look to the Shelly Plus 1 with the Plus Add-On, Shelly Plus Add-On Temperature Sensor |

what's the point of using the sonoff S60 socket since the same socket exists with tasmota already installed? this socket is the NOUS A1T. |

now i try to use template from this post {"NAME":"S60","GPIO":[1,1,1,1,224,544,1,3104,1,32,1,0,0,0,0,0,0,0,1,1,1,1],"FLAG":0,"BASE":1} |

I'm not familiar with tasmota and I want to flash esphome on the S60, where can I find the tasmota config for this plug so I can try to convert it into an esphome yaml? |

Found out that using 220V power is also an option. Just remember to use optoisolation - like cheapest Ali usb isolators. |

I think RYL was meant to be used for reducing the holding current of the relay coil. For example, a 50-ohm resistor would decrease the current flowing through the coil without causing the relay to turn off, which would reduce power consumption in the "on" state. Of course, this can also be done without a resistor by using PWM. This socket consumes about 0.2W when off and 0.6W when on, so it’s clear that power consumption was a consideration during the design process. |

Did the reflash and yes, a real challenge to desolder. What did the trick for me was to first melt the solder on the leg with less exposed side ( less area to heat) and at the same time, using a pair of thin claws pliers to pull up from the socket contacts. You only have to do that a bit and raise a couple of 2-3mm from the position, then let it cool so the solder hardens and won't go back. Repeat if necessary. What is sad is that in the end you still need to solder everything back an you don't know how thick those lines were in the first place, to make sure is still rated at 20Amps/4000W. |

Tried another way similar to the jig approach, but aiming at connecting to the PCB pad through the plastic case by drilling small holes and inserting pogo pins in the holes. This way you don't have to open the case at all, just drill 4 small holes on the case. I succeeded to flash 3 devices so far with this method, but one of them was a bit tricky by the way. Probably the factory assembly job alignment is not 100% consistent ? Or the drilling not perfect ? This is the template for the holes that you temporary fix above the plug : The printed template fixed on the S60 : Need to be careful about the angles of the drilled holes (template is aligned to the correct angle, should be thicker though to help this step) I drill the holes by hand, not using any electric tool, plastic is soft enough to do do Then you use a 3D printed template with pogo pins connected to the USB/Serial module : Pogo pins are spring loaded connectors, pretty convenient for this purpose and can be bought on Ali for a few bucks : STL Files for drill template and pogo pins support : |

Hello, I'm having some issues trying to flash my S60. I've connected the pins like in the graphic by @h3lmutek described in the last image. While writing this I read @helmutacp's post with the tiny 3.3V solder point on the board. And I then tested that (also change the jumper and pin on the CH340G) and it also builds the same WiFi net now on 3.3 V. As that is the "correct" voltage I will now stick to that. When I try to flash the device with Esp-Flasher (win version) I get When I try to flash the device with the Tasmota web installed I get I want to use the tasmota32c2.bin firmware. I feel like I am missing something extremely obvious. I hope I didn't fry my chip because I tried to use 5 V? Do I have to connect a certain pin to ground while starting up like with the ESP8266? Any suggestion help would be highly appreciated. |

Hi,
Purchased recently the sonoff S60 , they are esp32C3 based sockets with 4000w switching power advertised, and power monitoring, based on the CSE7759B chipset.
the socket is not easy to dismantle, it requires to have a nice soldering iron with a bg tip since you ll have to unsolder the earth "bar while you entered inside the socket.
the main entrance is as for the gosund/nous sockets , inside the female earth pin at the back of the socket.
once the small torx scew is removed, you ll have to pull the grey cover, but its a bit glued, so you have to pry with cisors or another cuting tool all around the limit of the greycover and the body of the socket, the gluing is not so strong, you ll hear some few gracks while applying force with ce cisors in the junction.
once inside, you have to unsolder the earth bar, you ll notice some solder on it, heat and pull with pliers.
the grey plasting protecting the Lan N female pins, is clippend on th board, pull it with a thin plier or by the help of a screwdriver.
then, you ll have to unsolder the L and N bars that are coming from the back of the socket, unlike the gosund, where it was screwed, those ones are not easily removable, you have to heat the huge amount of tin on each pad, and melt also the invisible amount of tin that is located behind the board, then pull side by side with thin pliers, repeat the heating/pulling operation until the board gets out. , i pulled side by side with long pliers holding the copper of the L an N. once finished, the board will come off and youll e able to access to the pins of the microboard. the tx/RX are available through some pads on the mainboard and on the microboard. i prefered to solder my wires for flashing at the junction of the mainboard and the microboard. i flashed the board with tasmota webinstalled without issues.
i used the 5V pad to supply and test the board before reassembly, and used my serial to usb converter to supply the board while flashing with 5V levels, even if not considered safe, it worked. if you want to take it the safe way, consider powering via the 3.3V pad on the microboard.
here is the identification of the pins :
as per my knowledge this is to date the only teardown/flash of this model, more infos are welcome
