This is not a rant, and I like using Insteon devices.
I'm an electrician and Insteon installer. I find when calling Smarthome for technical support regarding Insteon devices, one of the first questions asked is always what type of bulb am I using. It seems to me that there are more incompatible light bulbs than not.
In today's world of Title-24 regulations and energy conservation, it's not only neglectful but irresponsible on Smarthome's behalf that their controllers aren't more compatible.
I typically do full Insteon installations and emphasize scene capabilities. Most of the homes I work on use a variety of lighting types, but predominantly low-voltage. When I directly ask Smarthome if their dimmers are compatible, they always sidestep and tell me that they "usually" work.
When I had problems with Insteon timer switches used in bathrooms, tech support asked if I was controlling CFL bulbs. In California we're all but required to use CFLs, either that or some other form of high-efficacy lighting. How is Insteon planning to deal with LED lighting?
I think Insteon needs to show more concern for bulb compatibility, current lighting regulations and trends so their products will remain (become) applicable in near future.
