@Eric-Buhring great to hear that you managed to get it working. I have used solution like this (arduino+eth. shield+rf24) for some time.
Now I have switched to esp8266+rf24(version with antenna) as a gateway, it is a cool (and smaller) solution
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?

Hi @berkseo. Thanks for the suggestion, but could you describe in more detail? As for my TODO list, there is already a task to add 485 interface to the gateway. My latest device "xRoom" have this interface.
ps/ Where have you gone?
I have been working on "xRoom" shield. A small announce:
Do you remember the discussion about multinode? So, it will be available soon))
@tsunami My setup is max 50m radius and 433MHz standard power RFM69s so a small 1/4 wave whip works reliably even from a below ground pump chamber 10m away.
Your 915MHz at 200m SHOULD work on 1/4 wave if obstacle free line of sight, but you could try a 2.4GHz Wifi router at one location and use a mobile at the other to test if you can see the router. I can see at least 3 neighbouring routers identified on my mobile from over 40m away through masonry, 10 on the laptop, so it's a simple enough test.
If you can see the router on either, 915MHz should be rock solid with a simple whip and no need of directional antenna.
@sentur since it was launched 6 days ago, I seriously doubt anyone has had the ability to try it.
Anyway, please don't post the same question in multiple places. It wastes people's time. Most users don't have as much time as they would like to spend on projects, and wasting their time by splitting the discussion to multiple threads isn't very nice.
