I am about to replace my old Rinnai tankless water heater with a new one. The new ones have the optional Control-R wifi module that Rinnai touts as having SmartThings integration capabilities. Doing some searching it doesn’t seem like many have been able to make it work (and remain connected to SmartThings). Anyone have this integration with Rinnai working successfully?
If you have it working does it let SmartThings control the schedule of the recirculation pump OR is it limited to just requesting the pump turn on (ex. as part of a routine)? In a perfect world I would like to use it to only have the recirc pump enabled when we are home AND it is within a set schedule (daytime hours). No need to have it recirculating while we are away from home or while we are asleep!
My other thought was to just have the plumber put the external recirculation pump on its own outlet that I can control with a SmartThings switch so I can have the combination of being home and within a certain time window energize the pump (the pump would be hardwired to a temp sensor so it only runs when the water temp in the line has fallen too low).
