  KC868-D8 V4.37 new firmware update
Posted by: admin - 01-06-2022, 12:03 PM - Forum: News - Replies (5)

improvement:

when switch button work in "1 Key" mode . we let the "UP" and "DOWN" button ports with the same function. so that easy for connect two thick wire from two different places. such as this two thick wire not easy connect to one terminal pole.

Hello all,
Which one of your product do you recommend for home automation.
I have RaspberryPi with home assistant. I would like to control blinds and lights via HA and also via manual wall switches. And later adding some sensors and stuff…
I was looking at Kincony relay module but there is so many options that I dont know which to choose for the best output.

Here is shematic what I would like to achieve.
