My ISY/99i throws an error every time I try to view the log. I finally rebooted, now its hardware locked (ERROR light flashing). I think I need another unit. Then I can try to work the Insteon instability problem out.

The Thermostat is a T1800 with a humidity sensor installed. While the temperatures and mode status in the ISY/99i for the thermostat always seem to be right, the humidity reading is hit or miss. Do you think the v2.0 thermostat adapter could be flooding my network with bad humidity data?

I have had a very stable Insteon installation for 2 to 3 years. v1 Thermostat, 2 v1 motion sensors, 3 KPLs, 8 or 9 SwitchLincs, and 8 to 10 light/appliance modules, 4 RAPs. While my previous software/PLC combination was never very stable or very good, the Insteon network itself has always been flawless, at least in the context of the flaws inherent in the system. A week ago I installed a v2 Thermostat and an ISY/99i PRO/PLM combo. While the ISY/99i itself works fairly well (it has some problems loading scenes completely from some devices), now my Insteon installation is starting to flake out a little. I have had two KPL buttons lose connetivity to their loads (at completely random times, not instatntly upon installation of the ISY/99), and one of the motion sensors now only occasionally turns its associated light on and off. I had zero problems with the motion sensor before the ISY/99i and v2 Thermostat. Even weirder, I have an old X10 switched light that I haven't used in years start coming on at random! I know the ISY/99i doesn't have to be operational or present for Insteon scenes to work, but does the PLM? Could a bad PLM be causing the flakyness (or the lack of the PLC in my system?) Does the ISY/99i affect the Remote Access Points at all or reset the topology for these? Has anyone else every had similar problems in conjunction with their ISY/99i?

Michel, Thanks for that. I did see that in another post and that will work in the near term. Instead of one state variable, I can have 6 programs for each state, and in the "Then" action section of each program, they can run the 'Else" action section of each of the other states, making the states exclusive. So running Sleep State Then will set Sleep State program to true, as well as set all the other states to false.

+ 1 for variables. It would be nice to persist state somewhere other than on a physical device. Even if it was as primitive as a fake device with an on/off state. I like to have a current state for my house, e.g. Morning, Day, Evening, Sleep, Vacation, Emergency. I can use the state in programs to determine how the response to certain actions should proceed. As far as a case statement, any ability to have nested IFs or Else Ifs would work. Else Ifs would also work in your GUI.
