I love technology. I think it's great. I think it's the bee's knees. My house thermostat is failing. Many segments on the display don't work, the programmable bits no longer work, I woke up to a frigid house last week. I went on amazon.com and looked at thermostats. Internet connectivity galore, fancy phone apps, full color LCD displays, dashboards and logging, the works. I bought an $18 model that has a weekend/weekday programmable schedule. I know I can't trust these vendors. They care entirely too little about my security. Some day I may sit down and build myself arduino-based thermostat, but that day is not today.
