Linkind ESP32 Smart Switch - How To Flash Tasmota
10/03/2021 If you bought the dimmers, several of us have been working on reverse engineering the dimmer and have a proof of concept working! Thanks to Tediore and Tony's help on this process. Check the Linkind dimmer thread on the digiblurDIY discord and this GitHub Gist
09/30/2021 Deal is dead now... If you see it again let us know! 09/28/2021 5PM Central: Currently showing out of stock on the 4 pack for $20 switches. The singles are still available for $7.50 a piece. Buy the 1 pack on Amazon 09/28/2021 8AM Central: These oddly ESP32 equipped smart switches are running for $5 a piece in the 4 pack on Amazon (Prime required). That's a steal for many reasons which you'll see below!
Can we flash Tasmota on it? YES! The Linkind Smart Switch is rather unique. It uses an ESP32 chipset with Bluetooth support, two independent buttons, two independent LEDs (behind the small hole) of green/red and one relay. It ships with a non branded white screwless decora faceplate. The switch can also be used in multi-gang boxes as they have the additional mounting holes.

To open the switch, there 4 small torx screws in the face. I used the one out of the iFixIt kit but a small flat head screwdriver could also be used. Remove the four screws on the face and pull it straight up. There will be some tension as 8 header pins intersect the faceplate board.
Take note, the switch will not power up unless the air gap switch (reddish switch on the right) is depressed by the faceplate air gap insert (safety feature)
Pop the board out with a spudger or flat head screwdriver and flip it over.
