When it works, provides trouble codes and on/off status. Don't have recirculator on my unit. But noticed a week ago, app will not move past the opening splash screen. Email to customer service has received no response. Uninstalled/reinstalled twice, no change. Paid extra for wifi module on unit. Not worth the price.

Complete garbage. I got through the setup issues, and the app is apparently connecting to the device, but the data is often missing or wrong. Recirculation claims to be inactive. It's unclear what some of the controls do. For instance, there's a toggle labeled, "Tankless Power," with no explanation. Sure, I want tankless power. Or do I? Unfortunately, I bought the WiFi module mainly hoping to get more insight into or control over the recirculation process, which has been a nightmare...

Only the basic functionality of the app, meaning turning the circulation on for 5 min, works (most of the times). Other features don't work. The device's home screen doesn't update consistently, status screen doesn't show true status, and timers longer than 5 minutes don't keep the circulation on for the selected time. Scheduling worked for me for some time, but it doesn't anymore. I don't even know how this app still functions with Android, since it hasn't been updated for more than two years!
