WiFi_LightSwitch

Details

I have no experience with iOS development, but luckily my university has :) so i got an educational dev license to write a small app that contains a button (inApp and in Notification center widget) who sends a POST request to my Raspberry pi's apache server, the PHP script executes a GPIO command to trigger the relay.

This solution is very ugly, very unsafe and too expensive for more then one switch, so i'm starting to experiment with everyones favorite WiFi Chip: the ESP8266.

So my current attempt is a Python server on the RPI that recieves a POST/GET request from a website or iOS/Android-App and deliver a simple TCP message to the right ESP module to trigger the relay.

so someone has done the most of the work using the Arduino ide, so here you go http://iot-playground.com/2-uncategorised/40-esp8266-wifi-relay-switch-arduino-ide
when i finished my other Project i will make an iOS app (and web based app) for it
Progress

It was very quiet about my project lately and someone was faster than me :( http://www.esp8266-projects.com/2015/04/p2-wifi-web-power-switch-for-mains-mpsm.html
i decidet to change my plan a little bit, so from now on i will just use the ESP-01 Module (with nodemcu) standalone with an 230v relay and an optical coupler to check if the light is really on.
Pictures comming up soon.
Replace the RPI

Im working on a repacement with an attiny85, an ESP8266 and a simple 5V relay module (all together about 7€) and a python TCP server.
But connecting the ESP to an ATtiny seems to be a little complicated ^^
First working prototype

At this point it works already, but only with an rasperry pi next to the switch and a very ugly PHP script.

You only need a ESP8266, no extra µC like ATTINY. First flash new firmware and LUA programming language to the ESP, then you can directly use the ESP. For more information, searc the www for nodemcu

Are you sure? yes | no

http://hackaday.io/project/4206-esp8266-light-switch-temp-logger I don't know if this is quite what you want, but I'm sure it can be adapted for use with either a shift register or ESP-03 for more relays. Maybe even just use my html folder with the original esp-httpd repo on git if you don't need the temp logger part.

Are you sure? yes | no

Hey there! You might not even need an attiny for that, since the ESP8266 has some GPIOs itself, if you're willing to program it directly (I haven't done that myself but seen some guys doing that). Is your light switch directly switching the 230V or is it triggering a control voltage? Anyway, nice project!

Are you sure? yes | no

Hi davedarko,
thank you :) i already thougt about programming the ESP's own controller but at some point i also need to check if the light is on, and/or control multiple relays.. at first i think its simpler to just take an external controller ^^.

At the moment i use 5V output and 5V GPIO out from the RPI to trigger the relay. mabe 3.3V are enough to do that, i havent checked that jet.

Are you sure? yes | no

If you are using a raspberry pi to control it, 3.3V is enough to turn it on or off. The raspberry pi only have 3.3V on its GPIO's, so you are already there :)

Are you sure? yes | no

yes but the relay needs min 5V Power supply and all other Parts 3.3V max

Are you sure? yes | no
