Since i had one that worked (and 3 that didn't - amazon made a special case and let me return one 'one more time') I was actually able to isolate the exact problem - it's the USNAP module
I tried various combinations of my two thermostats, the modules, and location (Upstairs/Downstairs), and through the scientific method was able to determine the exact problem:
if your USNAP module says model "RTMV-01" -- 5 Stars, you are good to go, able to program schedules via your iPhone, and all the other internet goodness this was designed for.
If your USNAP module says "RTWG-01" -- 0 Stars -- quickly return this to Amazon, as it will not work. This will save you hours of resets, soft resets, secret modes, switching module sides, testing power with a voltmeter, crying softly, etc etc
To Sum up --- RTMV-01 ***** -- RTWG-01 negative infinity stars
Here are some counter points on other reviewers' feedback:
- yes, the top and bottom tabs are plastic. top is to cover the wires and bottom to cover the batteries. like all things, if you read the instructions carefully, and handle the tabs like they are supposed to be handled, they should not break easily and they did not for me.
- yes, this thermostat is screwed in to the wall, unlike some other thermostat where you have a screwed in wall plate, and then you 'pop' in the thermostat. i have one of those pop-in type at home, and the only reason they are pop-in type is because the batteries are at the back, hence you need to pop the unit out to replace batteries. for this thermostat, since the batteries are in the front covered by an easily removable tab, you don't need to take the unit off the wall to replace batteries. So having the thermostat screwed into the wall is not an issue for its design.
- i have 3 of their apps installed (iPhone/iPod touch, iPad, and Android), and they all work perfectly for me. The Android app is probably the least stable of them all, but functionally it still works. The website also works perfectly for me as well. BTW, you can provide your email on your website such that you can be alerted if your thermostat have not reported status to radiothermostat.com in 24 hours due to network issue. This just happened to me 2 weeks ago and it's great to be alerted. (turns out my DSL modem has died).
- wifi, once connected, never drops for me at all. the only reason i can think of for others with wifi dropping could be the distance between the thermostat and the router. i can't comment on the antena design of the router since mine is about 50ft from my wireless router, but if you experience wifi dropping issue you might want to buy a wifi extender or stronger wireless router. i have seen before where the use of microwave can impact wifi connectivity momentarily as they are on the same frequency (2.4 Ghz).
- the *biggest* hassle for me during setup is to connect the 'C' (power) line to the thermostat since that wire was not run from my furnace originally. since this thermostat is wifi and the wireless is constantly on, it uses more power than the batteries can provide. the batteries are there only for backup. if your furnace doesn't have a 'C' line to power the thermostat I believe others have bought a separate transformer to power the thermostat separately.
- at $99 from HomeDepot and cheaper here on Amazon, you can't beat the price and convenience.
- for exactly what I needed this thermostat to do (monitor temperature and remotely set the thermostat before I arrive), this thermostat is ready for primetime IMO, and does what it is designed to do.
The added benefit of a free service from radiothermostat.com to operate your thermostat using a web UI and not fuzz with all the router firewall and port forwarding is a BIG plus. I know because I have 3 other networked devices at home where I need to configure the firewall on my router and all the port forwarding manually, and that's not something I would recommend to non-technical folks to take on themselves. They just recently upgraded their firmware to open up the APIs so that developers can create custom apps to control this thermostat. I am hoping to see more apps developed for consumers.
Here are some cons I remember:
- I remember when I first set this up and picked WEP security, somehow it would not work right for WEP, and I had to pick WPA or WPA2. I think the recent firmware upgrade may have resolved this.
- There's a 'away' mode on the mobile apps to set the unit when you are not home. However, there's no such a 1-touch icon on the physical thermostat UI itself. Some folks including myself wish they would also put an 'Away' icon on the UI of physical thermostat itself.
Feel free to reach out to me if you have questions about setup and product as I am very happy with my unit, or you can use the forum on radiothermostat.com for Q&A. I just felt compelled to leave a counter feedback for this reasonably good product that deserves a better review.

Recently I had to install a new wifi router because my old one died (hence the courtesy alert email was sent from radiothermostat.com to let me know they have lost communication with my thermostat for more than 24 hrs). One thing I noticed is that once the thermostat lost connectivity to the router, it starts up its adhoc wifi mode again so that 1) you can see it in the list of available wifi sids on your computer as "thermostat-xxxx-xxx", and 2) you can then select to connect to it so you can configure it again. This is exactly what I did, point my browser to it, follow the wizard UI, and within 2 mins, my thermostat is connected to my new router without any issues. Once the thermostat is connected to a wifi router, it no longer broadcast itself as an adhoc sid, and you can connect directly to it by its assigned IP address from the router. BTW, the thermostat displays the last octet value of its IP on the top right corner of its LCD screen. Say its assigned IP address is 192.168.1.207, then it will display "207" in its LCD so you know. BTW, once my thermostat regain connectivity with new router, I received an email shortly from radiothermostat.com that my thermostat is back online again. What great free service.

* Looks like radiothermostat.com is now run by EnergyHub.com. The UI and software look slightly different, but overall functionality is still the same.
* My Android app also just got updated with EnergyHub's UI and flow.
* Definitely works with WEP now with the recent (late 2011 Summer) firmware update.
* Geeky comment: If you leave your iPhone, iPad, or Android phone next to your bed, then you practically have a thermostat remote control. I have found myself, at some colder nights, reached over to my Android phone, popped open the radiothermostat app, and raise the temperature slightly...what convenience...

* Just installed a 3rd one yesterday (bought here at Amazon this time) and went smooth as silk.
* I have noticed the price of this is device is starting to climb quite a bit. Was $99 at Home Depot before, now it is $169. I wonder if it has anything to do with LockState taking over the brand (trying to lock in the market and recoup acquisition cost?). Previously it was Filtrete Radio Thermostat, on Amazon it is now Homewerks, and on HomeDepot is LockState.
* So far all 3 installed Radio Thermostats are working flawlessly.
* I can testify that EnergyHub would send you an email if your thermostat loses communication to them which relays the communication to your mobile devices and browsers. I disconnected broadband for the last few months while my house was under remodeling, and I received a 'Your wireless thermostat is offline' email notification weekly just to let me know. This is a good free service for owners of this device.
The first issue was the wiring to the central heating and cooling system. I carefully read the instructions before I began. When I wired the unit up, I made a mistake.
w went to the white wire
y went to the yellow wire
r went to the red wire
g went to the green wire
.... so after all this, I attached the blue wire to "B" .... turned on the power, and smelled burning electronics ... immediately turned back off. I re-read the instructions ... turned out the blue wire went to "C" maybe this is "cyan", blue printer cartridges are labeled this way. After this rewiring, all worked fine.
**I did not need batteries as my red wire provided 24v AC power to the unit.
My second issue was connecting to the WiFi.
In the box there was a piece of paper which read "go to radiothermostat.com/wifi for instructions to connect to wifi".
1) on a windows pc, look for the wireless node which reads "thermostat**-**-**" where the *s are part of the sn of the unit.
2) then use a browser to go to 192.168.10.1 ... this brings up a html page inside the thermostat.
3) it asks you to choose the ssid for your wifi to attach to, and enter your wifi password
4) the next thing it asks is for a PIN which should be in the upper left corner of the screen on the thermostat. I could not get the unit to display this PIN. I performed resets, swapped sides for the wifi module, power cycles, tried many things I read on postings about this unit. No PIN .... No PIN ... No PIN ...After maybe an hour of trials, I found a posting which said you won't see the PIN in "simple mode". You know you are in "Simple Mode" if you don't see the clock outside of the programming mode. To get out of "Simple Mode" press and hold the programming button for 12 seconds ... until the screen changes. You will now see a 5 digit PIN in the upper left of the display. I was hoping this 5 digit number would also be on some tag on the unit, part of the mac address, or part of the SN. I read somewhere though that the PIN changes with a reset ... so this is some randomly generated number, not hard coded into the unit.
5) I then was able to complete the rest of the process easily online, setup my schedule, tested turning on and off through the website. All works
*** this seems like a great thermostat for a great price. My only complaint is the documentation in the box and the instructions on the website. As many other reviewers have stated, first time installation is difficult, but other than that its a great unit.
I hope my instructions here make the install process easier for someone else.
