How well does the Elk Z-Wave Interface (M1XZW) work? Is it as reliable as the handheld remotes for controlling the modules? I am starting to get fustrated with my HS USB interface because it keeps failing to send and I have to keep rebooting the computer. Last time I had problems like this I ended up resetting everything and re-adding each unit back into HS one at a time. It then ran perfectly for 6 months, until I decided to add 4 more modules and now it keeps failing or missing sending commands every couple days. I have no problems from the handheld remotes (even sitting in the exact location as the USB controller), in fact they actually seem to respond better now with the additional modules (which is what they should). I'm tired of waking up and seeing my outside lighing still on! I need a Z-Wave controller that works and is much more reliable!
