1. if DIYers want to use the RS485 adapter board with own ESP32 code, in furture, we will make a protocol document about it. it's private RS485 protocol.
2. if you controlled H32B Pro's relay ON/OFF by any way, not only by RS485, but also RS232, network http, mqtt, tcp, just relay state changed, it will update state to Apple Homekit app's ico.
3. sure, you can also use for dry contact sensor, set INPUT type = "Momentary".
when use for "Momentary", trigger relay by "down level" signal, if use for "Latch", trigger relay both by "down level" and "up level" signal
