Why pay $30 for such a device when you can order a similar product direct from China for $5? https://www.itead.cc/sonoff-wifi-wireless-switch.html https://www.i

It has the same configuration problems he mentioned but is easily flashable via FTDI.
- nfriedly 10y agoIncidentally, I reviewed a pre-release version of that device a few months back. I didn't try flashing custom firmware to it though - are there any instructions for that that I could link to from the review? http://www.nfriedly.com/techblog/2015-12-16-itead-sonoff-slampher-review/ http://www.nfriedly.com/techblog/2015-12-16-itead-sonoff-sla...
- StavrosK 10y agoIt looks like you connect 3.3V/GND/TX/RX to the four pins shown in this image: http://dl.itead.cc/IM151116002/sonoff-parts-without-433.jpg http://dl.itead.cc/IM151116002/sonoff-parts-without-433.jpg Then you flash it with PlatformIO as usual, except I'm not sure which pins are connected where, that would take some fiddling. I'll buy one to experiment with.
- StavrosK 10y agoOoooh, fantastic! Do you know where to connect the FTDI? I see that they're using a bare ESP8266 instead of a 12E. EDIT: Looks like they even expose serial connection pins. It should be pretty easy to figure out which pin the relay is on and which the button is on.
