Are there any new updates??

My app keeps closing mid-connection, before I can reconnect my tankless hot water to the app for on demand hot water. This app has been a PIA from the beginning, but this is now ridiculous!

Does not work

When I try to register, the app would not let me select the state (option disabled)

Not reliable

I’ve had this module for about five years now and no matter what the upgrade is, it still does not adjust the temperature of my hot water. The display says my water temperature changes, but as soon as I go back into the app, it is back to its original setting and won’t save. Also, it seems to disconnect randomly from my Wi-Fi and when I go to reconnect, it takes forever to get it to work. I’ve reset my Wi-Fi and reset the module, but still doesn’t work consistently.
