Purchased the shower controller and valve about a year and half ago and the app and entire system has worked great until now. It seems there is no option to fix it. It started when we received a new Wi-Fi router. I went into the settings to change the name and password on the app and once that was done, it acted like it was factory reset and now we can not reconnect the app at all. I wouldn’ t complain, we could just turn the shower on and let it heat up using the wall controller like old times, but…….. it only operates about 4 to 5 showers before shutting down. Now every 4 to 5 shower we have to go out in the hall closet where the valve is and unplug the controller from power and wait about 15 seconds before plugging it back in. It will then work for another 4 to 5 showers before repeating the process. The app is broken and freezes when trying to reconnect it won’t let us do anything. Phones aren’t old either. Using this on iPhone 12pro max

So I moved into a new home and my UI Moen shower screen kept turning black every two weeks. We called electricians, we called plumbers, and nothing worked, and it kept going out even with a dedicated circuit. Then we called Moen to assist us with troubleshooting and they told me that it was on my end and that it was my problem because I have 5 GHz Wi-Fi box and not 2.4 GHz. so then I was able to change my Wi-Fi over to the 2.4 GHz and go through the protocol 50 times to connect and I always get to step three of three and it times out and does not connect. So it’s not me it is this system and I have an iPhone and the text said to make sure to click on the droid and not the iPhone iOS. She said trust me. This is what works and of course that is not the case and I am getting so tired of calling service people and trying to set the system up myself with no help. I want a new system sent because I am done and this is the only way I can control the water into my shower room. It hadn’t been installed in my brand new house way before I ever moved in, and it wasn’t my decision, I would never get this ever ever….

Making the presets in the app is easy and they work great. I’m heavily into smart home integration with Alexa and Alexa routines. I was able to get one preset to work with Alexa. I can say “start R*****n’s Shower” and it starts both heads I have connected at the preset temp just like I want. The second preset I cannot get to work at all. Accept for that one preset that works, it defaults to turning on one shower head at 100degs. This happens outside the presets as well. Even if you ask Alexa “tell moen to turn on the shower to 107 degrees”. It looks like you can try to add the smart home device to an Alexa routine and select the heads and temp you want directly in the Alexa app without a mownpreset. it doesn’t seem to recognize those settings at all and you get the default one head at 100. Hoping the Moen team can teach this thing learn to talk to Alexa a bit better. I tried every command moen tells you to use and it’s always one head at 100deg but for that first preset.

First of all, I have read reviews, searched the Internet, and studied much on this shower mixing valve. This is what I would like to say - if you are planning a new shower, or a massive upgrade of an older shower - this system is amazing. It has the ability to non-traditionally build a dream shower, without being limited to inside the box thinking with mixing valves, plumbing, etc. I recently built a beautiful steam shower, using this and a Mr. Steam generator. Both are rather expensive, and both have a different rule set to the traditional plumbing. It requires electrical with your plumbing, and of course planning where you will install your controller. I do realize this review is for the APP only, so I will move on to that. The app, is mediocre, at best. However, it always functions and works as it should from my phone. My issues have happened mainly with Alexa. I can’t get her to turn the shower on to the correct preset. She will turn the shower on, everytime, but it’s at 100 degrees, not my 110. Also, the app doesn’t allow me to change the backgrounds or anything on the Controller - it’s rather vanilla - but it works. Over all, if Moen would give us some fun features like changing the background on the controller, maybe adding some personal touches we can change on the app to appear on the shower controller, that would be great. But I really think they need to fix the Alexa issue.
