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.

Works for needs but have request
Able to run recirculating pump as needed at home or remotely before getting home.
Wish I did not have to re-enter username and password each time application revised. Other apps do not require.
Latest version makes it impossible to login to the heater with my phone. Instructions coming from app do not work. Please fix.
