AutoShades were developed by me, David Cunningham, a retired aerospace engineer who relocated to San Miguel de Allende in Mexico. SMA is a peaceful old Spanish colonial town with many expatriates looking for a different life style. The climate is near perfect except for the afternoon sun which can be pretty intense on West facing patios. Cranking up and down the Coolaroo shades was just too much work for a retired person, so I spent 2 years developing this device, first as an Arduino based prototype, then as a production product. SMA is close to Queretaro, a large industrial city where I found excellent suppliers and subcontractors for the electronics assembly, sheet metal work, etc.
All our products are 100% tested before shipping, and they are warranted for 1 year. I hope you enjoy using them as much as I did developing them.
