ESP8266 Community Forum

I just successfully completed my first DIY home smart device project - smart light switch. The total costs are 7$ (ESP8266 controller, solid state relay, and a few other components). It is integrated into the home automation system via MQTT and OpenHab2. It uses WiFi and NTP to detect the time and day, and sunrise/sunset calculator to figure out when to turn the light on and off. It also can be used in the old fashioned way (from the physical switch), and can be manually turned on/off online. It monitors and reports the temperature of the SSR, and has dual thermal runaway protection features. The code is posted on github.
