rinnaicontrolr - Python interface for the Rinnai Control-R API

Python library for communicating with the Rinnai Control-R Water Heaters and control devices via the Rinnai Control-R cloud API.

Rinnai's API is completely insecure when it comes to reading information about your water heater. We recommend that you disconnect your water heater from the Control-R system until Rinnai fixes these basic issues.

This library is community supported. Please submit changes and improvements.

Support For

• reading and setting the temperature setpoint
• reading whether heating or recirculation is in progress
• starting recirculation

Limited Support For

• reading schedules, vacation state
• reading flow rates and service parameters
• reading intake temperature, outlet temperature
• reading the address of the device as entered into Control-R

No Support For

• creating schedules
• setting vacation state

Please submit pull requests to add support for your favorite values.

Installation

pip install rinnaicontrolr

Example

rinnai = RinnaiWaterHeater(username, password)
for device in rinnai.get_devices():
    rinnai.set_temperature_setpoint(device, 90) # make it annoyingly cold
    rinnai.start_recirculation(device, 15) # start recirculation for 15 minutes
    if rinnai.is_heating(device):
        print(f'heater is heating to a setpoint of {rinnai.get_temperature_setpoint(device)} degrees.')

Known Issues

• Rinnai's API is having trouble setting recirculation longer than 5 minutes even from their APP.

Future Plans

• asyncio interface.
