Hello everyone, and thank you for being interested in my project.
The PCB design has now been sorted out, and the prototypes are fixed from all bugs.
I am pleased to announce that the Gerber files for the design will be made available to the public soon.
I was also able to secure permission from ESPHome and Nabu Casa (the owners of the Home Assistant and ESPHome brands) to use the "Made for ESPHome" logo on the PCB for this project. A big thank you to Jesse and all the other people at Nabu Casa and ESPHome for making this possible. You can read about it all here: https://esphome.io/guides/made_for_esphome.html
