The mass introduction of LED light sources for home use has become the limit of the possibility of using dimmers in the old, classic form. The alternative control methods were infrared controllers and radio controllers, which could be controlled by a remote control. In the next phase, wall touch panels began to be created, and thanks to things like home automation systems, it was possible to control the entire building from one point. Dimmers were also not compatible with energy-saving compact fluorescent lamps, which largely displaced traditional incandescent bulbs from home use. Unfortunately, in the case of halogen bulbs there were significant problems in the form of a decrease in their durability. Electronic dimmers - slide, rotary knob or touch - were installed instead of the usual switches and could work with all traditional bulbs. There were some problems with it, such as the frequent acoustic effects of dimmers in the form of an annoying buzzing and the cost of the equipment itself, which significantly limited the spread of this control method. dim the incandescent lighting below the maximum level. Although the maximum brightness of the lamps remained unchanged, thanks to electronic dimmers, it could be reduced, i.e. The development of electronics meant that the simplest lighting control of the on-off type, used in cable circuits, was enriched by the ability to control the power of light bulbs, which allowed for the regulation of their luminous flux. The development of technology in conjunction with lifestyle changes meant that lighting control now plays the role of the most popular and cheapest function of an intelligent home or building. In recent years, the needs arising from the change in lifestyles combined with the development of technology have enriched the spectrum of available options.
For many years it was only a simple on-off control, which was done by a switch on the wall or on the power cord.

Filip Michalski, Electronic Engineer, and Cezary Skotak, CEO, from Cezos describe a speaker independent offline voice controls system, explain the technology and discuss the pros and cons. But there are privacy and security concerns. Voice control are mostly online speaker independent like Alexa, Google Home and Siri. Offline Lighting Voice Controller - An Alternative to Voice Assistants The historical evolution of light control by users started with a mechanical switch followed by potentiometer and dimming, touch panels and touch screens, gesture and movement detection control, and ending with voice.
