I have one motion sensor that for years has been my nemesis in that it gets ornery from time to time and gets to where it trips/senses motion only 80% of the time. (It turns the light on in the master bathroom--bad WAF.) I went into the ISY Admin Console to try a few things and discovered a problem:
When I click the "Options" button in the Admin console for any of my motion sensors, it starts with a "system busy" dialog, and then finally brings up the options box immediately overlaid with a "Request Failed" dialog.
My current motion sensors are the older 2420M's, but for grins and giggles I ordered and set up a newer 2842-222 unit, but the ISY treats it the same way. Screenshot attached.
Any suggestions as to the cause?
