Tasmota
Tasmota is a opensource platform.The Tasmota created the readymade binary files or firmware for the ESP based products like sonoff devices. The Tasmota is very easy to operate. If someone does not have any experience of coding, he can also create the Esp chip Based product very easily. The pre-compiled and pre-built code can be flashed into ESP device.The device can be configured using webUI.The tasmota has support for various sensor like temperature sensor like DH11 or humidity sensors etc. Further the device can be controlled through HTTP,MQTT,Webui and serially.So creating the product for the Home Automation is very easy.
