Yes, that would work.

thank for your links. i have seen some board already have ESP module with multi DS18B20 terminal, why you not directly to buy it? Because there are still improvements or deficiencies?

It seems like missed this question from you.

I cannot find a board with the following combination:
- ethernet. Wired is required for professional installation.
- appropriate for connecting 1-wire sensors (typically ds18b20) in star topology (separate 4.7kOhm resistor per connector on the board)

This would make the board work with almost any wiring topology. It would also make things easier to troubleshoot. It would work with a default esphome configuration. Etcetera.

I am still hoping you'll build this board. Otherwise I'll have to build something, either with an external pcb service or soldered breadboard. Not looking forward to either of those options...

your idea board is under designing. with ethernet +RS485, 4 GPIOs for DS18B20, already include separate 4.7kOhm resistor for every GPIO)

Looking forward to it. When approximately can I expect this to be available?

RE: KC868-A64 DS18B20 - admin - 01-28-2023

need about 2 weeks, later will upload photo.

Hello. I am very much looking forward to this. Do publish pictures once the prototype is there.

RE: KC868-A64 DS18B20 - admin - 02-17-2023

this is new board KC868-AM under designing.

I now understand that the 2-week term was for prototype design pictures. Do you have an estimated timeline for general availability to Kincony customers?

Kind regards,
