USB relay

I have this USB relay from ebay:

How could I control that?

No idea, a link to the item on ebay would be helpful. The dcttech.com website no longer exists.

A quick search though found this: https://github.com/darrylb123/usbrelay which gives you a small programme that will control it.

Here is the search, other ideas may turn up. https://www.google.co.uk/search?q=idVendor=16c0

and there is this HID node... no idea how it works though :-)

Thanks; I'm trying this now.
I wish npm could do restarts.

On the Raspberry it takes ages to install a package; it runs for 15 minutes or so, only to find out it misses libusb.h

So I install libusb2-dev (or something like it), try again, run 15minutes to find out it should be libusb1-dev.

I install that, and npm runs for 20 minutes to install npm install node-hid

Now I can do /node-red-contrib-usbhid

To be fair the readme does mention those prereqs.
