Funny, I'm a terrible speller but improper spellings just jump out to me. In this case it is on their new "FanLinc" also not identified as such on the controller. Anyway, I think that my issue may be that the fan that I'm dealing with was originally controlled by a Bond Device. There are no physical pull chains for the lights or fan. Insteon says when I link the switch with the FThe wiring from both the Bond and Insteon controllers are the same and the motor controls all work just fine. Just the light has been the issue only responding to Fast On commands. I was worried that I might have had an issue with the neutral line but it does not appear to be the case as all the motor controls are responding as expected. Thinking that there might be something inside the fan that interfaced to the Bond Controller (of course replaced by Insteon Controller) I decided to create a simple work around. Instead of double clicking the on and off buttons, I opted to just write a couple of programs to translate the 6 button single press on or off buttons to send Fast On and Fast Off commands to the fan. Seems to work just fine so far, just a short bit longer to respond. If polygot on my Polisy worked I would have gone down that path, but since Polygot does not work on my system even though I have the Zoos USB interface, I decided to stay 100% Insteon. When I decide to replace the Polisy with the Eisy or get my current Polisy working, then I might start looking into adding different smart devices.
