All devices mentioned below are 1st Gen GE/Jasco.
I have a Basic Rule that turns on an outlet and sets a dimmer to 20% at 4:00 PM. The same rule waits until 1:30 AM and then turns them both off. When I check in the morning, they are both physically off, but the dashboard and Device table entry shows the dimmer on and set to a random number (< 20%). If I click on Refresh for the dimmer it correctly updates to off. The Event log for the dimmer shows that it was set to the same random number rather than off. Once there was no Event recorded, but the light was physically off.
This morning as a test, I set up a new rule with the same logic but picked a different dimmer (10 minute interval between on/off) and it worked fine. Then I changed the time and interval on the original rule to test it and it worked as I would expect (i.e. just fine).
So, what is the problem with 4:00 PM - 1:30 AM? How I do I trouble shoot it further. SInce the lights are physically off, it's not really a problem, but it is an annoyance.
Finally, a general question: I assumed that the Refresh button for a Device just polled the device, but when I look at the Event log, an action is recorded that matches the current device state (Off, On, Set to a level). So, what does Refresh actually do?
