Hi, the KC868H16 is supported by Home Assistant ? If yes, there is a youtube tutorial ?
Thanks.

Hello everyone!

We are using KC868-H32 via Ethernet connection and have problems with PC app:

1. We cannot check the connection status while the application is running. So after the first successful connection, we don't know the current status. If something goes wrong, we will not know about it.

2. If there is no connection between the PC and the relay module, we can still turn the relays on and off in the app, but the relays will not switch in reality! And if we do this remotely, it is very difficult or impossible to check if the relays are actually switching.
Dear Kincony Team, what should we do? Maybe you have a new version of the app?
Thanks in advance!

Hello

I have a 32 channel relay board to control the blinds on the house. Is it possible to set the relay to turn off after a certain time (1 minute)?
