Can i use more than one unit on the network?

Unfortunately not.  Sainsmart have advised that only one unit can run on a single network at any time.

Can you give us some examples of how we could use this driver?

  • Connect lighting, sprinklers, garage doors/gates, motorised blinds/shades/windows/screens, door locks and other relay controlled devices to the system.
  • Combine with our relay to light driver to display as lighting in Control4.

Why can't i trigger all the relays at once?

Due to limitations in the device we can only send 1 command at a time per request. Each request is sent immediately after we receive a reply. As such you may notice a slight popcorn effect (for aproximately 100 milliseconds from our tests) especially in devices such as blinds and lights.Why do you only support OS 2.7 and above?

Do you offer showroom discounts?
We offer dealers a free showroom licence for demonstration and educational purposes.  See link below for T&C's and signup procedure.
