Minimum Load under cabinet Switches - Switch to LED

[spartysh32]

I had some non-LED bulbs (under cabinet fixtures) where we finally found LED replacements. Found out that the legacy (non-smart) dimmer switches won't power these new LED's since the load is too low.

opportunity knocks for high WAF TaDa - Time to switch the switches to smart switches. Should a switchover to my normal smart switch vendor use of Inovelli/Zooz work with these? Do I need to consider if the undermounts have a transformer, these also won't work?

I've been avoiding replacing the under cabinet lights since they installed the wiring behind the drywall, and wanted to avoid a major project. The non-LED have been bugging me for a few years though.

Not sure how any dimmer ever worked if there is a transformer? Wouldn't "dimming" the 110v mess with the transformer no matter what bulbs are in the fixture?
Are you replacing the fixtures or just the bulbs?

Also, yes, the Zooz (and I assume Inovelli) switches do not usually play nice with voltage transformers.

There are dimmable transformers. I have some in my house.

I have a dimmable transformer for under cabinet LED lights. If my transformer were not dimmable, I would not be able to dim the lights. But even with the dimmable transformer, I can't dim the lights (with a switch). The entire thing makes my head hurt.
Zooz and Inovelli have both told me their switches are not compatible.

However, over on this thread, Sebastien gave a solution. I have not yet implemented it...but plan on doing so once I completely get my head around it - I don't like doing things before I fully understand them.

Zigbee or Zwave dimmer for dimmable transformer for LED tape lights

I may have created a mess. The goal is to have a Zigbee or Zwave dimmer that will dim my undercab LED strips. The dimmer must not require a battery, and it needs to be no thicker than 1.2" deep to fit in the shallow box under the cabinets (that already sticks down more than desired..) Based on the understanding (perhaps incorrect) that all Zigbee and Zwave dimmers need line level power to operate, I designed the wiring for my low voltage undercab LED strips to be controlled by a line voltage …

I played with a dimmable transformer for some cabinet lights that I also trigger off a motion at night as a nightlight in our living room. The low level dimming is not great and I did what @Sebastien recommended and switched to a zen31.

In my kitchen I swapped the halogen 120v picks for 120v led pucks from Home Depot. Illum or something like that. A company from montreal. They have low voltage ones that operate off a transformer but also sell 120v versions. My wife dislikes led strips in the kitchen so I had to stay with the puck style.

They were dimmable in the past, prior to LED and on a dumb dimming slide switch.

That said, the glass cover for one of the fixtures was broken during the retrofit process. I may need to rethink retrofit of the fixtures.

I’ve seen led strips used, are those best for smart switch/light and functional adjustment?
