Culture and climate needs vary from country to country, so system needs and controllers are different
Real smart home systems are not the wireless gadgets that you often hear about that are available from many companies. Those products only offer part of the solution, like security system, lights, or air conditioning control. Additionally, they can only be used for small projects—typically those that do not exceed 4 to 5 rooms.
Culture and climate needs vary from country to country, so system needs and controllers are different. For example, the USA uses ducted-split with 24V thermostats in 80% of projects, while Mexico uses the mini-split more, which is also more popular in Southeast Asia, where 70% of air conditioning systems use this infrared-based system.
Moreover, in Europe, floor heating and radiator valve thermostats are widely used, while this technology is rarely used in the USA and or the Middle East.
Another difference is that while people in the Middle East love lights and may use tens of channels in each room, people in the USA usually use one light per room.
Also, priorities and needs for every customer vary from state to state and from house to house. While Audio Video Automation is of primary importance in California and Texas, security is more important in Africa and energy savings in Europe.
Accordingly, each manufacture tries to take the best share of its market. Thus, we found that USA manufacturers make better A/V systems than anyone in the world , while European brands are stronger in heating systems and lighting control.
