<div dir="ltr">Surprisingly my Arduino-base projects have gotten a MUCH higher degree of Spouse Approval, mostly because the Insteon, X-10 and Z-wave stuff was just too unreliable. After two or three times of the Home Automation stuff not doing what it was supposed to, my wife was done with it. The Arduino stuff required more know-how to get set up and working, but once it was it has performed flawlessly. I am also able to customize it based on her preferences. She wanted a button that would turn the fan on and have it run for 30 minutes. I already had a 4-button remote and was only using two of the buttons. A few simple changes to the Arduino program and I was able to make it do exactly what she wanted. <br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Jul 30, 2020 at 10:00 AM Peter Murray <<a href="mailto:peterwmurray@gmail.com">peterwmurray@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>My solution is to have a switch in-line with the thermostat, in our upstairs hallway.
