Bought a Tuya based dual smart socket here in Denmark for approx. 15 €, somewhat the same price as on Aliexpress. Quite easy to separate top and bottom parts with a hobby knife and a small screwdriver: To flash the BK7231N I needed to separate the plug part from PCB in order to reach... [Read more]

I would like to present a recently created contraption. I gave it a working name Supervisor detector. The ESP8266 chip and the SSD1306 OLED display are used here. I`m in a hurry to explain the principle of operation. The WIFI network is widely used, we use it at home, at work, in... [Read more]

Initialising To allow a device with no battery backup to keep time, NTP must be enabled and configured. The following script will configure an OpenBeken flashed device for a particular time zone and location. // NTP driver must be enabled for its functions to work startDriver ntp... [Read more]

I grabbed this from Ali to have a play. It comes with a CB3S module which is BK7231N. The VCC was just about accessible with a pin, so no soldering. Short boot log: BK7231n_1.0.13 REG:cpsr spsr r13 r14 SVC:0x000000D3 0x00401C1C 0x000033AC IRQ:0x000000D2 0x00000010 0x00401E0C... [Read more]

I will present a small sample script here OpenBeken turning off the device after a given period of time after turning it on. The waiting time will also be user-configurable, and the entire mechanism will be scripted manually, which gives the user ample modification options without... [Read more]

Design "for fun", vintage watch à la 90s, made on a contact plate. A gadget perfect for the shelf. :) I had an AT90S8535 controller in stock, and since I recently returned to programming, I decided to use it for something useful. The once exorbitant 8 kB of flash on board is rather... [Read more]

This one looked like it might be slightly different to the many variants of this device I've seen around (not one I've bought before anyway). It is from the Digitaling store on Ali Express and boasts 20A working current, though further down the page it says 16A. The relay is marked... [Read more]

Hi, Recently I have bought this socket which is similar to with some differences. Pinout is slightly different and has 3 relays. Device configuration, as extracted from Tuya: - Relay (channel 3) on P7 - Pair/Toggle All Button on P10 - WiFi LED on P8 - Relay (channel 2) on P24 - Relay... [Read more]

Bought a Schneider smart plug 550B6000 for Danish mains plugs: With a hobby knife and a small flat screwdriver, it is possible to open and separate the bottom and top parts. GND and 3.3V are easily recognized: On the PCB, there is a 10-pin power meter chip. It seemed to be a BL0942.... [Read more]

Hello everyone, I recently bought this fuse in DIN format with the option of measuring kWh consumption. This is the TO-Q-SYS-JWT model, a version similar to TO-Q-SY1-JWT, but with a built-in display where you can make changes to the fuse settings (undervoltage, overvoltage, temperature,... [Read more]
