Hi all, I’ve been working on dropping my local Tuya config for an Esphome based control too. Your code @rstcologne has been of great help.
I’ve used devices from M5Stack, which saves you the soldering and just use out of the box solutions.
I’ve used a M5Stickc with an RS485 hat (which has a 12v-5v converter inside):
Most of the yaml is identical, I’ve just included it for future reference for others. Main difference is in the m5stickc config and the gpio ports:
