Wow, what a waste of money

Wow, what a waste of money
Not having a "C-wire" for my heating system, my choices of smart thermostats is limited. The C wire is what provides constant power to a smart thermostat. My choices were, a $300 Nest or this $89 abomination. I was impressed with what was in the box. It comes with a cord to plug it in if you want or, you can use the supplied batteries. It even comes with something you can put on your furnace to provide a C wire. Other thermostats charge extra for this. Some houses use 4 wire cable to all the thermostats but, only use 2 of the wires. You could use this thing on your furnace and connect it to one of the unused wires. A really nice extra. In my house, they cheaped out and only ran 2 wire cable.With only 2 wires to connect, hooking it up was easy. As a really expensive manual thermostat, it's great. Turn the dial and push it in to set the temp. I'm sure this 7 day programable thermostat can even be programmed on the thermostat itself but, there are no instructions on how to do that. Not even on line. That's ok, I was going to use the app. I downloaded the app and, it wouldn't connect to the thermostat. I have an Android and the instructions only have screenshots for an iPhone but, the concept is the same. You set the thermostat as a wifi access point, you connect your phone wifi to that access point, you go in the app and select your regular wifi network. Similar to setting up an Alexa or a smart TV. Pretty simple, right? It wouldn't connect. I went through the process at least 10 times.I was just going to return it to Amazon but, I decided to call the support number instead. I had to look for the number online because, it's not in the manual. I was surprised to get someone very quickly. We stepped through the same process I went through about 10 times and it didn't work for them either. They said "We'll send you a new unit. It'll take a couple weeks". I should have said "Nah, I'll just return it to Amazon".I get the new thermostat and, it has the same issue. Won't setup through the app. I notice on this new thermostat that there's another option on setting it up. On the old one, you only had the option of setting it up through the app. This new one had the option of setting it up though WPS. There's nothing in the manual or the online instructions on how to set it up through WPS. I'll try it anyway. Maybe the screen will walk me through setup like every other WPS device on the planet. Nope. I hit "WPS" and it literally says "First, go to website to register. When prompted, enter device ID". It doesn't tell you what website. I had to Google it. I entered the Device ID and I got "Invalid device ID".Now, it's too late to return this to Amazon.UPDATE: I had emailed support asking for instructions on how to use WPS to set it up. I never heard back. A couple days later, I emailed support saying "Hey, I got the new thermostat. What do you want me to do?". No response.I called them and got someone on the phone fairly quickly again. We spent about an hour on the phone trying to get this one to work. "Take that batteries out, hit the reset button. Put the batteries back in. take the batteries out again, hit the reset button. Put the batteries back in". We did that at least 4 times. He couldn't get the screen he wanted on the thermostat. He said "I'm going to have to have my supervisor call you. It should be about an hour". 2 days later ..... no call.Update #2. A week later, still never heard back from them but, I finally got the thermostat to connect !!! I guess the 87th time is the charm. The problem now? The time is off by several hours. There's no option to set the time on this thermostat.Update #3 about 2 months later. When you change the batteries in this thing, you have to go through the whole process of getting it connected the the network again. And again ..... 87 times !!! I'm just using it as a regular dial thermostat at this point.

1.0 out of 5 stars SImple WiFi thermostat if you need WiFi and battery power on a millivolt system - UPDATE
Reviewed in Canada on August 4, 2018
UPDATE DEC 11, 2021
Now I would give a minus-5 rating. They fixed the app this year, and seemed to be stable for months, but now thermostat just disconnects. It does not automatically reconnect and requires removal of batteries and reset. This works for a few weeks. Again unable to connect to tech support by phone, and reply from email is that they are 'aware of connection issues' and are working on it. Same answer I got 4 weeks ago so hardly believe that they are 'working on it'. I am now completely fed up, and today will replace the Lux with an Ecobee or Emerson model - these do not work with millivolt heating units, but installation only requires adding a $10 relay as I already installed a 24v transformer to keep my Lux going without relying on batteries. Of course with transformer and relay, this will not work in power outage but I had already added a manual thermostat in parallel, to kick in if temperatures got close to freezing. This is what you should do with any smart thermostat actually. Lux - I really tried to stay with you, but this is goodbye.

UPDATE Oct 19, 2020:
Originally I gave this a 4/5 star review. I have reduced this to a 1 star (and would give it zero if I could) and advise people NOT to buy. Most of what I had written remains correct as far as installation. However, Lux was purchased by Johnson Controls in 2019 (after my purchase), and they developed and released a month ago possibly the WORST app ever. IT NO LONGER CONTROLS THE THERMOSTAT RELIABLY. So now I have a 'dumb' rather than 'smart' thermostat. What is the point of having this over a $30 manual thermostat, if you can not control it remotely?? Worse is their lack of customer support. My thermostat suddenly dropped having a solid connection I had for past 18 months, so I travelled 3 hours to our remote property only to find that the sudden disconnect was because Lux servers suddenly stopped supporting the old app. No message from Lux and no option to stay on old app. Installed the new app, connection seemed ok, and the app reported the temperature correctly BUT it would NOT control the thermostat. Poor UI design with scroll wheel that you have to keep trying to turn. Give me back simple UP and DOWN arrows! Very buggy software. If I manually change the thermostat, the app reports the change correctly with a slight lag. If I try to change the temp in the app, at first it looks like the temperature changes but then after 30 seconds , it reverts to the previous temperature! I tried login in and out, resetting the thermostat, rebooting the router, re-installing the app... nothing works. Plus with whatever they did in the firmware, the WiFi sensitivity is worse now, and I was marginal before. Even moving the thermostat right next to the router with full bars does nothing to fix the connectivity.

I have tried to call their customer support. They are not open on weekends. They do not have a 1-800 toll free number, only a New Jersey number that has long wait time. After 15 minutes on hold, I hung up. They do not respond to on line email form I filled in. They no longer offer a web based app to control - only the phone app. So fail at every level.

I am so angry that this company changed to this app without option to remain on the old app that worked, and left so many customers without access to their thermostats. You would think that they tested, but this appears like they released a completely untested and buggy app. Their customer support is non existent. If I had this over to do, I would have just gone the extra step and installed a small transformer and relay (as my heat system is millivolt) to provide power from AC rather than relying on batteries, and bought from a reputable manufacturer like Nest or Ecobee. I liked the previous Lux thermostat setup. I now hate my useless, non functioning Lux Geo thermostat.

PREVIOUS REVIEW:
This originally sold for much more but more featured WiFi smart thermometers became available and brought prices down. We bought 1 for remote location cabin, replacing a mechanical dumb thermostat. Here is what I like and don't like.

1. While it is one of few battery operated WiFi enabled thermostats, I personally would not trust a smart thermostat controlling millivolt heating unit without a 'failsafe' in a situation in which failure could lead to frozen pipes. A solution that gets around this is to wire a mechanical thermostat in parallel and set it to minimal lowest temperature. I was able to place the mechanical thermostat in a closet that was immediately behind the Geo. Of course if you are running a regular furnace, if the power is out, so is your heat regardless of what thermostat you are using.

2. We use a propane fireplace (which has three power vents) to heat a small cabin, and like most fireplaces it is millivolt system. All it needs to call for heat is closing circuit on 2 wires which is great if power is off as we can still get some heat. This thermostat is one of few WiFi themostats that will work with a two wire millivolt system, and was really straight forward to wire using RH and W wires only. The Lux Geo turns heat on/off perfectly well. BIG plus for the Geo. You can use a Nest or Ecobee, but they need 24V to work, so you would need to add a 24v transformer and wire in a relay to then provide an open/close circuit for the millivolt. We did not need all the bells and whistles (or $$) of higher end smart thermostats nor the increased complexity of a relay.

3. Lag can be an issue. The lag between changing temperature on app and having the thermostat respond can be quite long if you are using battery as power source. The unit delays communication to protect battery life. I added USB power and it is much better, usually within 1 minute. On battery, could have been 10 minutes or even more! I have noticed that sometimes I have to enter the temp change twice - not sure if this is related to server lag and time out at Lux end. Just need to check if accepted.

4. Power: There is no icon for which power is being used ie USB or battery or C wire. I know that USB or AC from transformer is working as I can take the batteries and the unit still operates. As a note, when you put the batteries back in, there is a message asking whether you are installing NEW batteries? Clearly Lux knows that system will fail with weak batteries and again that is a concern if you are using this in remote location and you are unable to physically check the system. Using USB to power adds a wire from the bottom that decreases the clean look. I added a 24v AC transformer (Fyve Global unit bought on Amazon) and fed the wires to thermostat through the backplate, to make the install cleaner. Easy - one wire to C, the other to RC (no polarity on AC so does not matter which wire) and remove the RH-RC jumper that is in place so that they are not connected. Works great.

5. There is no indication on app of WiFi communication being intact between unit and router or between app and the unit. This would have been really helpful to have. Maybe they will add in future as other smart thermometer apps have.

6. WiFi sensitivity is ok but not great. The icon for WiFi does show 2 bars with the router where it is and that is enough for control. If I put the router further away to get only 1 bar, the unit still seems to work ok. Better to have more bars I think - dropping a WiFi signal would not be good . On the plus side, if the router loses power, and WiFi lost, Geo will re-establish WiFi contact once available. I have our router on a UPS just in case.

7. You can invite family or friends to control thermostat through the web site. Adding email addresses sends an invite to them to set up an account and control the temperature. Good to have this feature.

8. Not listed as feature, I think that settings are put into non volatile internal memory so if all power fails (house AC and battery), it will remember the last settings.

Overall there are clearly some plus and minus issues on this thermostat but overall my impression is positive for the things it does, that no other units do. Looking forward to arriving at a warm cabin this winter.
