A simple ESP8266 relay switch and weather station with Blynk
I had a bunch of esp8266 micro-controllers laying around, so why not make something useful out of one of them ! Blynk is a simple iot platform that just works and is easy to set up in 10 minutes , so why not :) By using their simple blink sample sketch , got my phone app hooked to the esp !. It's as simple as it can get. Blynk can do a lot more stuff than turning on lights and stuff but for my use case this is enough. Down below is the simple schematic I made for the project using easyEDA. Some photos of the build. Blynk app on Android
