I'm having Sonoff T0 UK Wifi Smart Switches all over my house and recently I wanted them to be connect to a different Wi-Fi network. I was planning to move all of them from my 4G router to my new Fibre router for smooth operation and doing so, I can take my 4G router anywhere I want without disturbing my smart switches.
There are few important things to be remembered when you're moving these devices between wireless networks and I like to share them with you before I explains the procedure.
