  • Smart thermostat = this adaptor
Just stop looking for any other adaptor! Seriously, if you got this far then youve made it to the bestest, easiest, quickest way of connecting your thermostat other than having an hvac cert guy come into your home and rob you blind of your money for the simple task of running a wire through your walls and floors. Don't do it, just buy this adapter trust me. If I felt like walking downstairs to take a picture of it I would add it to this review but I don't feel like it so your just gonna have to take my word for it. I might be lazy but I don't lie about it!!! Seriously it's exactly what you need. Peace out ... show more

  • Just what I needed for nest learning thermostat
Does just what I needed. I was tired of charging my nest learning thermostat every 3 days since my furnace is so old it doesn't have a common wire. After hooking this up I've not had to give it a second thought. The cord is nice and long and it's been plugged in for months without any problem

  • Easy to install
I haven’t been able to use it as it’s summer, but it was easy to install and looks much nicer than the one we had before

  • Didn’t solve the issue.
The best thermostat still has low battery.

  • Worked
Had other power supplies and would not work so I tried this one and worked instantly. Not sure what the difference is as they all had voltage, but this one did the trick ! Nest thermostat

  • Works with Sensi Wifi Thermostat
I installed this with a Sensi Wifi thermostat on a 2-wire, heat-only boiler system. Followed the installation instructions on Sensi's website, and it works well.

  • Didn't work
We plugged it in and couldn't get power running through it which is weird because its a plug with just wiring but it didn't work for us during install and had to get another competitors plug which worked on install and gave power to the nest
