Poor App/User Design
Just installed and I was able to use the app to get it set up, but what a poor user experience! Rinnai - spend a few bucks to get a user experience designer instead of an engineer to think about the user experience for the app! Examples: - you can't set a timer for the system to turn on at 6 am and turn off at Midnight (12 am). Instead, you have to say 6am to 11:30pm (because it gets confused by the two am timers). - using the QR code to register the heater is a great idea, but it couldn't read it and kept saying it was invalid, forcing a manual registration. - there's an icon in the lower left corner of the app titled "Priority" but there's no explanation of what it does! - if you have larger text settings on your phone, you can't read the text in the app (it doesn't scroll) - Product information, which I assume should load if you've registered, is blank - Demo is useless. Doesn't do anything. Instructions would be more appropriate. All that being said, the wired controller that I have on my other Rinnai is equally non intuitive. Rinnai really needs to invest in some user-centric designers.

Thank you for your detailed feedback. We've heard you and are excited to announce a new app coming out in the very near future that addresses many of your concerns. Please look forward to it in the next month or so and let us know how you like it.--Tashay RinnaiAmerica
Does not stay connected to WiFi
The device connects and disconnects constantly. Spent hours with support on the phone. Have two more smart controllers in the garage along side the Control-R (Genie garage door WiFi module and a WiFi light switch). Both maintain WiFi connection, but the Control-R is flaky. Essentially unusable.

Must Have
This is a great addition to our RUR-98. I had no issues connecting to my wifi. I did have a slight issue with pairing the push button but Rinnai customer service helped me out with that. The ability to use a voice assistant, in my case Alexa, and having the app for different commands/controls is awesome. I like that I can set multiple schedules for recirculation and that they are in 30 min increments vs. 1 hour increments on my other controler. I do however hope that there will eventually be 15 min increments added to the scheduling capabilities on the app. I read that you have to change the recirculation setting from economy to comfort, however Rinnai customer service said that is not necessary. There are alot of bad reviews on this unit and the app and I'm not sure why. I will update my review if things change but for now in my opinion this option should be built in to the units because it's a must have!

Horrible product
Never connects to the internet, app is garbage, and to top it all off its impossible to actually reset and have it reconnect to the internet. Thoroughly useless product that isn’t worth the cost of the plastic it’s made of.
