I have been trying without success to get 2 sonoff devices to join the wifi network.
SONOFF TX T3 WiFi Smart
SONOFF SMART LED CONTROLLER - L2-C
They pair and work fine if I use a old wifi extender that connects to the 2.4 network i have created for IOT devices.
Do any of you have any ideas how to get these devices to work directly with my Wifi 6 Access Points ?
