Your kc868-a series product series look very interesting. The kc868-ai in particular looks like a great fit for home automation.
I have star topology cat5e wiring. I would love a product that would let me connect multiple 1-wire sensors (ds18b20, ...) cleanly. Without soldering pull-up resistors. Just like you enabled for binary sensor input.
Is that something on your road map?
Thank you. I understand that. I have implemented ds18b20 like that before. It looks bad. It is more difficult to maintain than it should be. The most likely to go wrong would be a 1-wire bus unhappy with the sensor network topology. I want a clean, maintainable, wired solution.
My dream board for temperature sensing I would call KC868-AT:
- ESP32 board
- all free gpio's exposed
- per gpio: 4.7k Ohm pullup resistor between vcc and data preinstalled on board
- per gpio: screw terminals for vcc, data and gnd on a removable screw terminal block
- ethernet (like KC868-AI, KC-868-A16, ...)
- (optional) a set of ds18b20 sensors and wago style clamps to connect them
- ready-to-go esphome config
This should be relatively easy to build with 8 temperature sensor slots. No need even for any gpio extenders.
Will you please build this? I will buy a few. More people would buy this!
