I'm using ISY 994i, v.4.2.30. A few days ago my PLM (2413S) seemed to stop working (scenes were not getting turned on/off programmatically) and after running several diagnostics, I was able to convince SmartHome to send me a replacement. Now that I've installed it, it looks like I have good comm and I can control devices just fine. But I can't turn on/off devices by turning on/off scenes. No scenes work anymore. ISY tells me the devices are on, but they aren't.
I've tried restoring devices, and I've tried deleting all devices and re-defining them in ISY. Scene Test appears to work, but the devices are not actually turning on/off. I also tried moving my PLM and ISY to another location where I have another router. I'm baffled.
