KMTronic USB Relay

Dear All,

I bought a KMTronic USB eight channel relay controller. In Domoticz I have selected KMTronic gateway USB. But how can I control the 8 relays? I can't select de KMTronic as hardware when making a new switch. Or do I have to make a LUA script?

Thanks for your help

I think you can create a virtual switch from The switch tab And selected The km tronic source.

It was a Conflict between two USB ports. Solved the problem. Now de relays are available in device tab.

Thanks for the help.

I have an 8-relay box too, but as an RS485 version with a USB converter. When I select KMtronic Gateway USB, no devices appear. I have tried different things for hours now but can't get it to work.

I also have two heat pumps, that when connected to the USB converter, they work without any issues. I have now disconnected the heat pumps and have only connected the relay box, but it doesn't seem to respond. The log says it is ready to read, but is not responding. Anyone have an idea?
