I start this topic as I am going to experiment with 2 RFXtrx units.
On my Vera Edge I have already installed a RFXtrx433 to control my Somfy sun screens, it works perfectly. Also it montors my KAKU doorbell, and triggers sending a Veralert with a snapshot of an IP camera, mounted near the frontdoor.
Next step... I ordered and received a (proto) RFXtrx868 unit. And I would like to use it next to my existing RFXtrx433 unit.
But... Vera Edge has only 1 USB port, a little stupid

that I did not think of that before...
So my 1st question is:
Can I extend and use multiple USB ports on the Vera Edge, e.g. by using a USB hub, anybody tried this ?
When I start experimenting with my Visonic sensors and the RFXtrx868, I will share my experience in this topic.
