Light Group Dimmer is a custom integration that groups lights and dims them
together — but with a twist: it mimics Hue-style weighted dimming instead of
forcing every lamp to the same brightness.
The problem
With the built-in light group, dragging the brightness slider sets every member
to the same value — you lose the balance you carefully set up (e.g. bright
ceiling + dim accent lights).
What this does
It preserves the relative brightness between lamps. Dim the group down and the
bright lamps stay proportionally brighter; dim up and the darker lamps get more
headroom — just like pressing and holding the slider in the Hue app.
Features
- Weighted dimming, validated against 37 real Hue reference measurements (±1–2 %)
- “Press & hold” behaviour via a configurable delay window
- Fully event-driven UI — brightness, color and color-temp sliders don’t jump around
- Color temperature (Kelvin) and color pass-through,
transitionsupport - Works with any HA lights (not Hue-only); smart plugs / on-off devices can be
members and are handled correctly (ignored while dimming) - YAML or UI configuration, plus a diagnostics download for easy bug reports

It’s a spare-time project and I’m not a professional developer, so feedback and
bug reports are very welcome — the repo has an issue template that guides you
through it.
