Hello, there is very fast and impresive project for home IoT. One night during normal browsing I find arduino library for controll 433MHz wireless outlet which is laying around for few years without usefull task. After few minutes I completed all need parts from drawer and put all together. Afer half of hour I had functional 2ch android controlled sockets. Good think to implement to project is Wifimanger library for easy SSID/pass change without reprogram ESP. In this fast project I omited it…
