I've just compiled from svn, here are my first impressions, with a somehow larger z-wave network (a bit below 20 nodes, some at the edge of reachability).
- The polling works (thank you !), I see the devices being polled, and I could see in the logs that the first run has updated the internal status of some devices
- 30 seconds seems a bit short because with that number of devices, we are almost continuously seeing activity on the zwave device. IMHO every few minutes would be enough
- I saw only a few devices respond (7-8). I didn't get time to look carefully at which ones responded and which ones didn't
- I haven't tested changing a device manually because I'm at work, will test tonight. Back to work now
