    • I got some of these Arlec Smart Plug In Sockets from Bunnings. Apparently they are Tuya devices but I decided to take the brute force approach to putting ESPHome on the.

    First challenge was getting the tri point screw out. I had to buy a special screwdriver for this.

    Once I got the screws out, it was easy to unclip the case and open it.

    After tracing the circuit, I decided to solder wires to the board and connect them to my USB->Serial adapter. The only tricky part was that you have to hold GPIO0 at ground when you power up the esp8266 to get it into flash mode. I just held a wire on the tiny GPIO0 pad on the TYWE2S.
