For those of us that want to conserve energy, now available is a driver to monitor and control Rheems new Performance line of electric water heaters. With the driver, you can monitor the current water temp, change it's setpoints, and most importantly, change from Economy to Performance mode depending on your home's current needs.
Add a command to switch to Economy mode (or turn the temp settings to lower) when your home is in Vacation mode. Switch it back to Peformance mode to heat the water up quickly when you put the system back into Home mode.
Rheem currently does not support this functionality on their Gas fueled heaters.
Rheem's optional Wifi connectivity unit is required.
A Rheem online account setup is also required.
