I purchased a Yun because the Uno and Ethernet Shield would not connect to my home network (never listed on router). The Yun appeared on the router right away. I have a Seeed Relay Shield and successfully loaded the test sketches to activate all 4 relays. What I want to do is use the Yun and Relay Shield to open a garage door via a local network web page from an Android smartphone. Can anyone provide help with the sketches to accomplish this?
