>> Why do I need WIFI on my lights, coffee maker, or dishwasher? Well, you don't. WIFI is definitely one way to go, but Z-wave is a better way, imo. Here's a use case for me -- I think last year DHH did a podcast where he talked about air quality and the effect of CO2 on cognitive function. After listening to it, I got a CO2 detector and wired it to a Pi. I had it set up to fire a webhook to IFTTT to turn on my HVAC fan via a NEST connector when a certain CO2 threshold was hit in my bedroom (it would get quite high overnight). I have since found out that my ensuite bathroom fan is more effective than the furnace fan in lowering the CO2 in my bedroom, so having a smart wall switch on my ensuite fan allows me to automatically turn it on or off based on the air conditions.
