just bought 10 pieces of the 1014 in order to operate my house as a smart home.
the relays are connected to a raspberry PI through a usb hub (i've connected 2 of them but planning to manage 4) and they get the commands to open and close the circuits from the PI.
When I connect them directly to a PC thought the hub they work great but once I do so with the PI the relays work wierdly: sometimes they complete the task of closing the circuit and then let go after a while (different times) and sometimes it seems that the light just jumps on-off and goes back to the mode it was in before.
I suspect that the 5V that the hub gives it isnt providing enough current. I'm planing to buy a hub with an AC adapter hopefully it will work, any thoughts of other solutions?
