Compatibility depends on the dimmer type, the minimum load and the driver input design. Leading-edge dimmers oscillate with capacitive loads; checking the compatibility list, calculating the minimum load and switching to 0-10V or DALI are the three effective fixes.

TRIAC cuts the phase, 0-10V uses a DC analogue level, DALI is a two-wire polarity-free addressable bus, Push uses a momentary button and wireless is bridged through a gateway. Whether a site is new-build or a retrofit decides the wiring options, while the lowest dimming level and smoothness depend on the driver design.

Use shielded twisted-pair signal cable kept apart from mains; the distance limit comes from interference rather than voltage drop. When paralleling, size the count against the current available on each controller channel.
