I have a boiler for heating and my old thermostat used just R and W wires. There was a third, common wire, but unfortunately it wasn't hooked up on the boiler end, and wouldn't be easy to fix. This little device made my ecobee3 lite smart thermostat work very easily.It's inexpensive, and has a little box ("wall wart") that plugs into the wall, and a long cable with two pins. The pins are VERY flimsy which makes them hard to push into the receivers in the ecobee, but it worked well enough. I put the cable along the wall underneath the ecobee housing. I plugged the two pins into RC and C (I put the striped one in RC and the blank one in C... I don't know if that matters but some other reviewers of similar products said to do it that way). Then the original thermostat wires went into RH and W1, and everything is working great.The little plug-in box doesn't seem to be getting too hot the way some reviewers of similar products have complained. I am taking off a star for (1) flimsy pins (2) a rattling sound in the plug-in box as if something wasn't firmly attached in there. But value for money is definitely there, as long as it keeps working for long enough. (Even replacing it every year or so would be cheaper than doing the electrical work to get the original common wire working.)

Installed it to Nest3, because the battery is dying and no good battery replacement found. Hooked to C-wire and Rc-wire as said in the booklet, but didn't work and gave a message of low-power on Rh-wire. Then I placed the wire in Rh socket along with the red wire and worked fine.

We had an old round thermostat with only 2 wires and replaced with a Honeywell Wifi thermostat. The wiring guide in the booklet doesn't account for adding this adapter so I'm sharing what I did in case this is helpful to anyone in a similar situation:R (red) wire to RW (white) wire to WStriped wire (from this power adapter) to CSolid white wire (from this power adapter) to RcRemove the connector pin between R and RcIt works wonderfully!Beware that R and W wires are not necessarily red and white, check how your old thermostat was wired and label accordingly.If you have an old thermostat and you suspect there is not C wire behind it, or even if you are not 100% sure... I would advise you to order this adapter before you take it apart to check the wiring in the wall. I learned it the hard way because once you take it off it is very hard to put it back on and we got stuck without heat while waiting for this adapter to come in the mail. Don't be like me! Order your adapter and don't start the job before you receive it - you can always return it if you find an extra C wire in your wall.Also a note that we did not need to alter the wiring in the furnace panel once the thermostat was set up. As far as I understand, this is only true if you are NOT finding a C wire in your wall, because it means there is no corresponding C wire to hook up on the furnace end.And a reminder that old thermostats very ofter contain mercury, so look up local resources for disposing of it!

I was really looking forward to getting this installed and using it for my ring. Everything worked fine at first on the first one. I started it up before officially installing my ring and drilling holes to avoid all that hassle (spoiler it didn’t matter) after I had drilled and officially installed, I went to plug it in and it wouldn’t turn on anymore. Tried the plug where I had tested it out first and still nothing.Called Ring and they tried helping me, but sadly couldn’t. They were gracious enough to replace for me.Turns out that in the app it read that the adapter was at 34V (10 more than the max requirement) which explains why it burned it.The box and adapter all say 24v so I don’t know if maybe it’s an error by manufacturers or error by the ring app (which is unlikely since it never turned on again)So when I got my second Ring in the mail I was almost dumb enough to try it again, decided I would use the adapter on another device that took 34v but I found out that the adapter no longer worked… tested it with my volt tester and nothing came up anymore.Really disappointed in this product.

Let me start out by saying I used this to add the "C" wire for the nest thermostat. I bought the Nest because it said it could be used with a two wire system. When I went to set it up it would not allow me without a "C" wire which I did not have. This thermostat is now controlling a 70+ year old wall heater and it works like a charm. The hardest thing for me was finding anyone that would describe how they wired this to the nest. I have a low voltage system. 24 volts. I have a red and a white wire from the wall heater to the thermostat. The Nest that I have does not have the "RH" and the "RC" connectors only an "R". With the Nest I connected red to "R" and white to "W". Then I added the wiring from this transformer. I connected one wire to the "R" along with the red wire. Yes there is room for both of them in the one connector and the other wire from the transformer connected into the "C". I plugged the transformer in and everything works great. The thermostat shows a constant 3.17 volts on it's battery. This a such a simple and easy fix for people like me that wanted an internet controllable thermostat but do not have a "C" wire.
