AliExpress Arduino Nano NOT Vera Compatible
I purchased the Arduino Nano listed in the Store section (http://s.click.aliexpress.com/e/eQZBQ3Rj6), this comes with CH340G USB chip which is not supported by Vera. There is a workaround using ser2net but I have not been able to successfully get this working. It is also tricky to get this USB chip working on OSX as there is not a signed driver for Yosemite.
The eBay source also linked in the store does appears to come with FT232RL USB chip although I have not ordered one of these yet this should be compatible.
You can still use it without problems for sensors.
