ESPHome
1

well I got this from Amazon thinking it would be easy deal, i was able to load ESPhome standard config on it, but no documentation or anything on which GPIO pins control which relays?? I have tried guessing some and so far I can only switch one of the GPIO27 to relay3, but cant figure out the rest
anyone got this one before?

so quick q, I copied the code from two other working boards I have, they are the LILYGO TTGO T-Relay ESP32 type…how come those two dont need the separate output and switch defs? it seems its combined into one section, but for this new board they need to be separate? is that just a a hardware thing?

You can switch to the gpio switch.
It depends on your application/preference
