Want 5Ghz Wifi home automation

When will home automation devices become available to run on 5Ghz WiFi? 2.4Ghz band too crowded. I can see almost 40 WiFi networks from inside my home using WiFi analyzer. Impossible to get anything working without interference. So I have dual band router and use the 5Ghz band exclusively and disabled 2.4Ghz band. I have Samsung Galaxy S7 smartphone which works fine on 5Ghz. Been looking for simple home lighting WFi control but cannot find any light switch devices that use 5Ghz band. Crazy that industry doesn't realize that 2.4Ghz band too crowded to support any kind of home automation unless you live very far from neighbors.

 

I'd recommend going with z-wave home automation products. It uses 900MHz and mesh networking to link all the devices.
