KC868-Server is a super smart controller for smart home automation and industrial automation control. KC868-Server smart controller support MOSFET output and wall switch connect to it directly. Also have analog input and digital input ports. The most important is integrated Raspberry pi CM4 module. Also integrated ESP32 module for you to write your own code. It’s very powerful and flexible.

Hi, I have a KC868-32L and I want to use it to control the roller shutters.
I was looking for a way to set an autoOFF delay in the application and I can't. I searched Scene and I can't set the delay in KBOX app.
please help me with a video or useful information.
thank you!

Can the H32BS controller output 24VDC? I guess we can mix 12vdc and 24vdc as far as output is concerned as long as the VIN has the desired voltage. How do we ground the 24VDC output for a specific VIN assuming the same controller will have 12VDC VIN as well?

Thanks much

I located your youtube video for H32B wifi config which is very good: https://www.youtube.com/watch?v=2AViXMH8yHM
Do you have a similar video for ColB wifi configuration?
