I've been able to get MySensors working with HomeGenie using the MQTT gateway. It doesn't have two-way communication or software-based pairing yet, but I'll work on those in the future.
@evb Still haven't had a chance to look at your PR, sorry.
Yes, the database tends to grow I have about 80MB after a year of use. Just added a function to delete all messages older than, say, a year.
Sorry. Hek, I using this code. Vera3 find relay and it works, but also appears 3 door sensors instead of 3 temp sensors.
I try to use the my arduino board only with sd18b20 sketch and it work's and show temperature. Is it sketch suitale for vera?

sensor id is not the same as node id.
sensor id = 255 is used for internal stuff like id request and battery level for node. You can assign 0-254 to your own attached sensors (to the arduino node).
Ive started out with openHAB2. I was using a Ethernet gateway and tested the mysensors binding but found the combo was too limited. I much prefer having the MQTT gateway and the data be accessible to anything that subscribes, although I also now use openHAB to republish its item changes to MQTT as well which is probably a better approach.
I don't think the main new features in version 2 are very mature at the moment as well, discovered things for example get put in to a non human readable database and the web ui's are not fully functional.
With that being said I'm using node red to provide node ID's and configuring items manually and since beta3 it's been solid as a rock.
