I built this test fixture many moons ago, I understand the esp libraries I used have been updated and my code no longer compiles. That said, I still have one of these running non-stop since I compiled it way back. Only one GPIO was tested, however the Arduino code should be expandable if you update code to current ESP Arduino libraries and make code changes as per the folks that modified my initial work.
The selection between Zigbee, espHome and Tasmota most likely depends on your current device platforms and whether you want to add to your current platform or add a new platform to your HA universe.
Good hunting!
