Login issues

Awful app. Logs out in the middle of a session and I constantly have to log back in.

Unable to recognize Serial Number of water heater

I’ve tried both the QR code and the manual serial number from the data sheet the app suggests to use for setup. Will not recognize the serial number and connect my heater.

The worst app

Can’t even log in, and this is the third waterline heater replaced under warranty in 6 years . Don’t buy one and their customer service managers are the worst . DO NOT BUY!

Unstable App, Nonexistent Support

Created an account over a week ago and still cannot log in. Every attempt produces an error message claiming a support ticket has been created, but there is no apparent way to contact support or follow up. An app that won’t let customers access their accounts, with no meaningful support available, is fundamentally broken. Extremely disappointing.

Waste of iPhone space

This app is useless. Will not find my series 900 hybrid water heater.
