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?
