I've had the unit in operation about 4 months. It's been working great. I bought a new Rheem water heater too, the Performance Platinum 38 gal. Tall 12 Year 36,000 BTU Liquid Propane ENERGY STAR Tank Water Heater. The wifi module functions are very limited considering today's technology, but it does work nicely. I saw many horrible reviews I was very skeptical but I have a feeling that the people who like the unit don't leave good reviews, we only seem to hear the negative from people these days. That said, it works great, I'm able to lower the temp when I leave for any length of time and turn it up before I get home. I love it! The only feature I wish it had was the ability to review past performance to see how often the unit is actually running. I have the ECOBEE thermostat and LOVE the data it generates. If you're a green guy, buy this, I think you'll enjoy the energy savings and reduced wear and tear on your water heater if you travel often.

wish I could do less then 1 Star
I’m truly amazed how bad this unit is, the water heater first had bad flame sensor thank you Rheem QC I’m not sure if its partly iPhone app or all the main unit. What a peace of crap. The EcoNet I have leak probe elevated and has never touched any moisture but it always reports lead. Second iPhone app is worthless, it lets you set temp remotely but didn’t work. It says a temp so increases it by over ten degrees then wait the water heater doesn’t respond. Only way to get temp you want it unplug the EcoNet unit completely and uses dial. Glad I wasted extra money on this crap. Shame on HomeDepot not making their main product provider live up to the quality they promote.

    Easy to install and connect to our wifi. The associated app offers limited capability (set temperature and receive alerts), but the alerting functionality is important and worth the small cost of this item.

      Arrived unuseable: socket for attachment of wire set is not seated correctly inside of the wifi unit housing, making connection impossible. Wish I had time to chase these junk parts around--basically covering for manufacturer's incredibly poor quality control. I must return this device.

      I this unit that I bought with the water heater. Two days after installation I got an Alarm Alert A102 that there was a water leak. It was a false alarm. There was no water and the leak sensor was completely dry. I sent a response email to the alert email then read "We are unable to respond to inquiries sent in reply to email." There was no way to dismiss the alert and no mater what I pressed on the screen I kept getting a window telling me to email a plumbing contractor. I was unable to do anything with the Rheem app--I couldn't change the temperature or activate the vacation mode. The email was sent from "help@econetsupport.com." So I went to the website econetsupport.com and it just said "Coming Soon." I realized that the Unit might be bad (bad sensor, broken wire, etc) but I also realized that the support for this Unit really sucks. I returned the unit today, three days after installing it.

        Be prepared to be frustrated. Plus once you get it working it doesn't do much. OK, so in spite of all the justifiably bad reviews, i bought it anyway. I'm a geek and it was only around $50. After trying to set it up using the Android phone app and getting nowhere, I sent Rheem an email and got a response that said the Android app is messed up (ya think?) and try it with another device. So I tried with my Windows 10 laptop and it set up without difficulty. Once the WiFi Module was set up that way, the phone app seems to work OK. However, it just doesn't do much. Yes, you can set the water temperature, set vacation mode, and see current error codes, but there's no energy usage information, run history, or error history. Pretty useless unless you travel a lot like we do and want to take the water heater out of vacation mode when you're on your way home from a trip, so you can take a shower shortly after you walk in the door. I would only recommend this device to geeks like me or folks who travel a lot and want the ability to turn on and off vacation mode remotely. Rheem has a whole lot of software work to do to make this an attractive product. One final thought, these Modules must not be selling, the Module I received had a date code in 2014, 3 years ago.

        Not a must have!
        First off, make sure you buy the correct version. There's one for GAS water heaters and one for Electric Water heaters. They are NOT the same!!! They have completely different connections. Setup was a snap. Once you connect it, you need to set the Hot water temp to the B setting! The temp in the App shows 119 degree's. If you want to raise it up, it'll give you a warning at which time you can cancel or confirm. I don't need to raise it, so I just canceled. There's some basic settings to do. In the end, the App will tell you if you have any Alerts. I've had none, and unless there's some issue, you shouldn't have none. There is a Sensor to put in your heater water pan it should be sitting in, in case you have a leak, it'll warn you of that. There's also a button to put your heater in Vacation Mode. In the end is this device really needed? I never turned the heat up/down on my old heater. I also live in this house, and vacations are rare, so Vacation Mode?!?! It's not like I can't just go into my Garage and look and see a leak, or turn the dial if I needed to. At the $80 price point, it just seems pointless to buy. At this newer $50 price point, maybe. I did it, why not, being a geek. Is it needed? Not really. I can tell people how my Heater is connected to Wifi though!!!! Then I get the "Of course it is" response. The App works on iOS or Android, so others are out of luck. I'm using it on my iPhone 6. The App will work with more then 1 system at a time.

        Hello JBDragon,
        I appreciate your feedback concerning how easy this was to set up and how smoothly everything went for you. One of the most important benefits of our Wi-Fi device is that you'll receive important alerts and notifications about your water heater­­-including leak detection alerts-straight to your mobile device. Quick notification of component failures can assist in getting your contractor alerted quickly. More importantly, leak detection can aid in piece of mind should any water be detected in your drain pan --- allowing a quick response to prevent water damage. If you need any help with these alerts, please call us at 800-255-2388 and we would be happy to assist you. Best Regards, Tiffany rheem

        Don't Geofence Me In
        This simple device works OK. I have not had the occasion to use the "away" feature, but I assume it works based on the capability to control the heater when at home. It allows more precision in setting the heater temperature, and it actually works. I set mine at 130 F and tested at the kitchen faucet with a good cooking thermometer and the water Temp read within a degree of 130. The installation instructions are straight forward and simple enough, although I did not know what "white water" meant, and a search online got me nowhere (I just did as the instructions said). The Rheem ap and set-up online was easy. I would have rated it higher, but the ap really doesn't explain how the "away" feature works. It appears to work on a "geofencing" interface which seems odd to me; it is like the heater will turn off or something if I am a certain distance from my home. I'll figure it out when I go somewhere. Oh, and the wire that plugs into the heater controller does not lock in place. It seems a bit loose so I taped it down.
