So I have a few Insteon Micro Dimmer Modules (2442-222) that I just purchased. I have many Insteon devices in my house that I have been using for years (mostly their standard in wall switch dimmers). I am using the same ceiling LED fixture throughout my house and have many (>20) on the regular switch dimmers without any issues.

The problem I am having now is when the microdimmer is linked to a switch dimmer for control (IE switch is master, dimmer is responder), if I have the microdimmer at anything less than 100%, it will flicker if there is Insteon traffic anywhere else in the house. When I say flicker, the symptom is I get 1 to a few quick flashes where the light goes to 100% then back to it's programmed level. If the microdimmer is at 100% or 0% you don't see anything but I suspect that whatever is happening in the control logic it is still happening, you just can't see the flash as there is no difference between 100% and the setpoint of 100%.

One interesting note is if I do a factory reset, before I do any linking to the device, I can manually set it to a dimmed level using the on/off buttons on the micromodule. Then if I send Insteon traffic around the house it will be stable most of the time, but will still occasionally flash with traffic. As soon as I have it linked into my ISY through a powerline modem, it will start to flicker on any Insteon traffic.

I have reproduced this effect with multiple dimmer modules in multiple locations.

Has anyone seen this or know anything that might help?

Thanks,

John

I have 2 of these. Each powering one LED can recessed light bulbs. They are 5-6 year feit 9w, 75w equivalent, LED can lights. They occasionally get the dreaded traffic flicker.

I have a number of i3 paddles, 7 of them are controlling the exact same bulbs in the exact same fixtures, some up to 5 LEDs per switch... no problems.

I'm thinking of order the blue/yellow flicker capacitor kit from insteon. I've been avoiding it as both of these will be a mining operation to get out. But given the weather I should get going

I would think this has to be a logic issue because it is tied to when Insteon traffic is present. Those type of devices are supposed to help when the light is just flickering because of the type of dimmer Insteon uses, basically smooth out the power from the chopper. I don't think they would help in this case as it is a short burst of 100% power, then back to the dimmed set point.

I made a video showing the issue I am having:

Your timing is interesting because these have recently been coming to a head for me as well. My Insteon network is mature and in cleanup / maintenance mode. In fact it's shrinking as all remaining Insteon sensors are migrating to Yolink.

It's now dealing with these 2 little leftover problems... And more of a WAF thing.. "why does that flicker sometimes?"... and it bugs me as well. We'll be selling this house in a few years and want to get this solved and move on to other things

I just exchanged emails with Insteon about these flickering / flickering on Insteon traffic, and their recommendation is try combinations of the flicker capacitors; that they can help in many cases but sometimes don't do anything. As much as these micro modules are a perfect solution for where they are and what they're doing, it's a mining operation to get them in/out. I don't look forward to one more journey in there.. let alone possibly more fiddling with capacitors that may not do anything.

Everything else Insteon in my house works as expected.. so I'm raising the white flag on this one and replacing the micro dimmers with micro on-offs. I originally made these rooms dimmers "just cuz" and in several years of use in these active living areas, they have never been dimmed in any setting other than me testing it during installation. In other areas we do dim Insteon n-ways and it works great but not at these locations.
