Sonoff Dual: iTead WiFi Smart Switch for connecting 2 devices - Be aware: someone requested me if i've the unique firmware dump for the for this device, regrettably i do no longer. If you flash your own firmware onto this tool, you achieve this at your very own chance. I purchased a number of these wi-fi smart switches from itead, but didn’t like that you had to use their app and cloud server to apply them. They use an esp8266 microprocessor, so i desired to see if i may want to re-application it to load my own firmware.

And beginning up the case, you find sets of unsoldered pins, the horizontal ones is used for a 433mhz rf module, which i did not purchase. The vertical one brings out the rx and tx pins of the esp8266 at the side of three.3v, gnd and a gpio pin. The usage of the "tasmota" firmware /sonoff-tas... It's miles viable to attach a bodily transfer among gpio14 and gnd at the sonoff board. This permits the tool to connect with united kingdom lightswitches that don't have a impartial connection. Diagram / schematic next step - set up into the ceiling light!.

To location an esp8266 into program mode, gpio0 should be low at some point of electricity up. The schematic shows that gpio0 is pulled excessive with a resistor and that the transfer (s1) is connected between gnd and the equal resistor. Hi, i by the way broke my button – down proper leg. (Ot outher side of board and near diod. Are you able to supply me factor to resolder it ? I'm able to’t get it from schematic. Thank ypu.

You need to access the serial interface. The four serial pins (3v3, rx, tx, gnd) are available inside the middle of the pcb, right next to the on-board button. More moderen version of the sonoff module provide five pins underneath the button, ignore the pin furthest away from the button (gpio14) if available. The square pin proper subsequent to the button is the 3.3v line. On my sonoff the analog pin became not connected to some thing, but i did manage to solder a wire directly to the esp8266 chip and produce it out to an unused header pin. While i get a danger i’ll make a post displaying the way to try this.
