PIR in 3.3V and ESP8266-01

[engberg]

So I'm just gonna document here..

Got my FTDI232 device and found drivers here:
http://www.ftdichip.com/Drivers/VCP.htm

Then connected the FTDI232 and the esp8266 this way:

And followed the flash instructions here:

I had to do it twice, before it worked..

It only runs on standart power, if I connect both the VCC and the CH_PD to 3,3V

Hi Justblair please could you share your PIR Sonoff configuration and rules?
Thanks

I am using a PIR module with a Sonoff wireless smart switch.

https://www.itead.cc/sonoff-wifi-wireless-switch.html

I modified the PIR module to bypass its 3.3v power regulator and then connected the PIR sensor to the 3.3v power header in the Sonoff switch.

Works very reliably in my kitchen switching my under unit and other spotlights. Love it. The sonoff is very reasonably priced, and basically gives you everything that you need to complete the project.
