Dims ok, but not to a low level
The switch works fine, except that the dimming does not go down to a very dim. The previous flat Insteon switch did.

Can’t set the low-end trim
I haven’t found any way to set the low-end trim for LED light bulbs. I love the dial control for a dimmer, but the fixed 10% low-end trim is way to bright for many LED light bulbs.

I3 Dial works OK but Hub app allows control but only half of the 8 devices installed work with th...
I3 Dial devices were installed in our kitchen/dining room remodel. 2/3 new wiring and 1/3 old. Manual setup of 3 way operation with two of the I3 Dials worked fine. The rest are 1 way. Getting them to link with the old Hub app was problematic some worked fine but morth than half took 2, 3 or 4 tries. None worked using the supplied address entered directly. The Hub 2 in our home has been operational since 2012 and there is a bus tie between the to 120VAC legs right at the breaker panel in the garage. There were 23 existing devices on our system before adding the new 8. All were working and still appear to be. I also was not able to make changes to the start delay and the start up dimmer setting when I tried adding 2 different new I3 Dimmers to a scene. I disabled the old Hub app on my iphone and tried the new Director app and things are worse with that app. With the Director App half of the new I3 Dial Dimmers show but say they can’t be controlled and don’t respond. Once in a while the none responders will turn on but then you can’t change it to off or dim it. All off the old Insteon devices seem to be working with the new Director App. Killed the Director app on my iphone and went back to the Hub app which allowed me to control the new I3 dimmers but I still could not make changes to the devices in a scene. Note that all the devices work when the knob is turned and pushed at the wall switch. On I3 knob dimmer does have severe flicker if the knob is rotated fast and you have to go to max and slowly rotate the knob to get it to work. There are 10 Feit Candalbra LED bulbs on that fixtujre that previously worked fine with and old analog dimmer.
