Homeowners unable to retrofit existing three-way fan circuits with modern dimmer switches without rewiring

DIY homeowners and electricians encounter incompatibility when trying to install two-wire dimmer switches into existing three-way fan control circuits, requiring either expensive rewiring or abandoning the dimmer upgrade. Current solutions either demand full circuit reconfiguration (costly and time-consuming) or force users to accept non-dimming controls. This creates frustration for people wanting to modernize their home automation without major electrical work.
