7 years ago I don't have a sonoff unit so I do n't know about mac address being changed. However, there is a AT command to change MAC address in ESP
AT+CIPSTAMAC="18:aa:35:97:d4:7b"

I am waiting on more switches in the mail.... Oh the long wait! LOL I programmed this first sonoff, and before I did, I wrote down the Mac address. When I programmed it, the mac address is now different. Where did this come from? If it programs the same mac address, then the devices won't work together. So my question, does anyone know if the mac address changes with each unit, and if not, where is it in the script so I can put the original mac's in the devices. Thank you!
