Well wife likes to keep it at 24 during the day. So our heating bills are still high.
I usually buy the tp link wifi switch. They retail for 50 but are 2 for 50 when they go on sale.
They also have a dimmable led bulb for 25. I have a smartthings hub so have a combination of wemo, tplink, leviton (mostly tplink though) and they all work seamlessly.
