Did a rather short (sarcasm) live stream showing the process to break open the smart switch, identify features, flash tasmota, setup the template, etc. It was my first time doing this switch model and first time doing the real live stream.

I also showed the bonus of the very cool new dimmer switch I've been working with on and off. It's very close and works out of the box right now as it is with a few Tasmota rules.

Had a lot of fun and let me know if you'd like to see more of these (hopefully shorter next time!)

We are showing additional tips and tricks on the KULED WiFi Smart Switch; 3-Way Config, Long Press Actions to control other devices, LED Control, and LED Dimming.  Learn how to use Tasmota rules with the various configurations in your projects.

Watch the previous video of how to flash the KULED Smart Switches as we are setting them in a 3-way configuration!  https://www.youtube.com/watch?v=4nX90vhAniQ

Parts List (to flash Tasmota):
KULED SmartSwitch (2 Pack)
USB FTDI Adapter(for Flashing, set jumper to 3v3 - NOT 5 volts) Male Headers
Jumper Wires

The KULED WiFi Smart Switch unboxing and Tasmota firmware flashing tutorial.  These switches have been welcomed by many as an easy solution to their smarthome projects.

Can it replace a Sonoff Switch?  You be the judge. One of the easiest devices to flash, with NO soldering!  Don't forget to set your flashing adapter to 3.3 volts!

Parts List:

Verify your header layout is the same as pictured, some switch variants have labels the layout is different.
