Rinnai Tankless Water Heater & Control-R Module Integration


I purchased a Rinnai tankless water heater a couple of years ago with their “Control-R” WiFi module. The integration with the module and mobile app ended up being horrid so I aborted using it completely and the hub became a $200 paperweight. I’m now wondering if it can be integrated with HA and become a useful tool in my smart home. Instead of using “dumb” timers I’d like to integrate with things like my home security system and other sensors to control when recirculating starts & stops.

A quick Google search came up empty for integrations with the Rinnai and I’m wondering if this is anywhere on the horizon for integration with HA?



I currently have my Control-R module juiced into Google Assistant for connectivity, but it would be nice to bring that into home assistant and not have to ask Google to get Rinnai and then go through their list of options to verbally enable the recirculator or up the temperature.
