You could try the arduino plugin in indigo and skip Vera altogether
The MySensors Arduino plugin doesn't work for me. I posted on the MySensors forum to the developer about it, but he's not been online there in a few months it seems. The MySensors plugin shows communication messages in the debug log in Indigo, but when you actually try to create a new device using the detected sensor module, the popup is always blank.
Another user on MySensors posted the same issue...I actually had just replied on his thread. I'm thinking something was updated in Indigo that hasn't been updated in the plugin to function. I think the source code is posted on the plugin's GIT page, so I may see if I can look at it and learn what it is doing.
Would be awesome if the developers of Indigo could look it over and work with the MySensors guys to fully implement that wireless protocol into Indigo natively. Would open up a world of sub-$20 sensor modules.
