You have to register as a pro to connect to Bluetooth

I’m not sure how this oversight occurred but to be able to actually connect to a tankless water heater that has Bluetooth, you must create a professional account and tell the app that you install water heaters otherwise if you register as a consumer, you will NOT see the option to connect to Bluetooth. Also you cannot control the settings of the water heater unless you go through a “quick setup” each time and the app says the warranty can be voided if you don’t give it the “correct information” whatever that means. I cannot believe the lack of usability of this app. You might as well not have it.

Finally seems fixed

After a year of fighting connectivity issues with this app, it finally seems like they may have finally fixed it. It’s been working for a while now. Whoever has been working on all of the recent app updates, it’s very much appreciated

Laughably terrible

This is a absolutely terrible app. After spending $100 for the wifi module i am shocked at how terrible this is. The metrics it gives you are delayed to the point of uselessness. I wont buy another Rinnai thats for sure.

Fix your garbage app

Zero. Worst app and customer service ever. Avoid at all costs if considering a tankless water heater.

The app doesn’t connect

Horrible, it doesn’t work. I’ve tried repeatedly to use the serial number and registered the product but it continues. He says it’s an invalid serial number.
