Update on my last post..
I just checked the Zoom buttons on My House remote and they don't function either. These did function a couple of weeks ago, and I seem to recall that the remote presets worked a few weeks back too. It may be that X10 has disabled the functionality of the remote controls on their servers, or they are filtering out the control data, and not passing it thru to the local computer. It's possible that the X10 servers are experiencing problems when passing the control data and they have disabled it until they resolve the server issues. That may have been the reason the servers have been having problems lately?
This is just a guess on my part, as I have no evidence that this is the case.
But, if that's the case, I wish they had the integrity to post said issues in the forum and save us a lot of pointless troubleshooting.
