How to flash Lumary wifi led strip controller using esphome

I have lumary led strip, like this.

And this is the board

How I can flash it while the board is not have any place to connect it to serial port?

I can see the Tx and Rx test points in your top image.

Hi there, did you have any luck flashing the lumary rgbcct controller?

I am also very interested to hear if you were successful!

Unfortunately, I was unable to flash it so I bought a MagicHome controller instead, but now the newer version of MagicHome is not using esp so you can’t flash it, I’m now using esp to made my own controller
