KMatle Expert Licensed User Longtime User Nov 17, 2015 #1 I would like to check my windows and doors at home. There are wireless trans-/Receivers but I need a cheap & simple solution (monitor, if a reed contact is closed or not). Any (simple) ideas?

Q: I've heard that some modules have soldering problems (oscillator is turned 90 degrees by mistake). Hope my module is ok. Any experiences about flashing fw?

KMatle Expert Licensed User Longtime User Nov 18, 2015 #4 Just fount this: http://www.esp8266basic.com/editor-interface.html 1. Flash it on the module 2. Call the build in web-editor and code basic on the module(!) 3. One of the examples: Get status of the build in GPIO ports 4. Call it via httputils with parameters (like a php script) Will try it at the weekend

Simply use this library in Arduino IDE by following the simple provided instructions and you are good to use it like a regular arduino with WiFi onboard. The firware will be reprogrammed each time by the library. https://github.com/esp8266/Arduino If you use it with Blynk http://www.blynk.cc/ then some arduino examples are provided. This is quite simple just give it a try you will be impressed by the power of the combination ESP8266 / Blynk. BTW there is different variant of the ESP8266. http://www.esp8266.com/wiki/doku.php?id=esp8266-module-family I own many of them, but the most usefull for prototyping is the NodeMCU one. It is intented to be use with LUA scripting, but I prefer by far to use the arduino library. I'm sure you will have a lot of fun with these new toys
