Rheem Water Heater Climate Driver Installation

Climate Icon

The Rheem water heater Driver is Allonis' application that provides a 2 way real time integration with a Rheem electric water heater controller within your myServer user interface. It is reliant on Rheem's Internet cloud service.  The Driver supports more than one monitored heater installations.  As of this publication date, Rheem only supports this capability with their electric peformance models, and not their gas fueled models.

System Requirements

  • myServer
  • Climate Family App
  • Working Rheem thermostat controlled electric water heater
  • Rheem WiFi connected to Rheem's cloud

Before attempting to create a new Rheem Climate Device in myServer, you should ensure that your heater is installed, powered up, and properly configured for use with your heater system. Refer to the Rheem Owners Manual and Installation Instructions booklet that came with the Rheem Wifi module.

Also, you’ll want to ensure that: 

  • Create an Rheem user account.
  • Connect the water heater to the Rheem cloud service and ensure the data is populating their website.
  • How to Install the Rheem driver on myServer

    • Purchase the Climate Family license from Allonis
    • Shutdown myServer5
    • Run myInstaller Installation on your myServer PC
    • If you are connected to the Internet, you should see the Rheem driver listed in the Climate category. Select and download it.
    • After the driver is downloaded, click to install it.  It will install two files into the myServer Drivers directory.
    • Restart myServer

    Configuring the Rheem Driver

    • Don't manually add a thermostat into the Climate Family.  The driver will do this for you.
    • Double click on the Rheem driver in the myServer Device Drivers window.
    • Click on the Authorization tab
    • Type in your Rheem user ID / password and click "Discover" button
    • You should soon see a new Climate device added to the Climate Family / Driver
    • You can rename the water heater in the Climate Family Manager Friendly name.
    • Click ok on the dialog box and the driver should then start talking to the thermostats via the cloud.
    • Adding the device and authorizing it will automatically add a new thermostat to the Climate Family.

    Variables will be created starting with "climate_X_yyyy"  with your current temp, set points, mode of operation settings.

The Allonis sample webpages should now show you the thermostat on the Climate page with data.


  •  It can take four minutes for the myServer commands to be sent to Rheem cloud, to the thermostat, acted upon by the thermostat, reported back to the Rheem cloud, and then updated within myServer.

  • On initial discovery, the driver will setup with the name of the thermostat that Rheem cloud has been configured with.  Once the thermostat is setup, you can change the name in the Climate Family.
