Hello in this home automation project, I have explained how you can make an 8-channel home automation system, in this automation system you can control upto 8 channels through –  Mobile, Ir remote, and also with manual switches, if there is no internet connection still you can control with ir remote and manual switch in offline mode. If the device is suddenly off because of power cut then after power is restored it will remain in the same state because the last states have been saved in its memory (like arduino eeprom). Follow the video tutorial for step-by-step guide. Check below i have shared all the project file
