Ahh I think I see now. I'm under the impression that this integration works for the Rheem Econet product line. What I don't know is whether a regular Rheem water heater, if used with the Rheem smart wifi module, would essentially operate like a Rheem Econet.
Is there a way to get Available Hot Water Status?
By "Status", do you mean the % of water that is hot, or the temperature of the water, or something else? Several of these attributes are exposed, just depends what you're looking for.
% of the water is hot is what I'm after.
The Phone app shows this
This is what my hubitat is showing
I don't believe that attribute is exposed by the OP's Hubitat driver. As I see it, you have two options to get it:
- Ask @klinquist if he can expose it because I know the API makes it available; or,
- Use the Home Assistant integration (either cloud or local) which curently exposes that measure, as per the below from my HA setup:
. Yes I'm also very interested in getting percentage of available hot water left. I'm interested in making a rule which when available hot water gets below 10%. It swaps to high demand mode and when it gets above 50%, it swats back to heat pump mode
Can you Give me more information about option 2. It would be nice for @klinquist to add it to the Driver, but are you able to utilize that % in your Hubitat rules as it is?
Yeah sure. Do you already have a Home Assistant instance? If so, you can use this integration to pull in Rheem EcoNet including the % hot water variable you want.
Then, you can use HADB which allows you to pull HA entities into Hubitat where you can use % hot water however you want.
Not sure how much experience you have or how much knowledge you have with Home Assistant, so the above may be totally insufficient.
Thanks, I Don't currently have a HA instance, but I did briefly look into building one for "better looking" dashboards.
Ideally I could just get %available in habitat and build a rule, but I will look into doing the HA bridge.
Thanks again
Apologies if I've overlooked or misunderstood something fundamental here. We just (as in an hour ago) got a new Rheem furnace installed with an EcoNet thermostat. I've got my account set up and connected to the thermostat through the app on my phone. I've installed this integration via HPM. When I attempt to add the app, I'm prompted for my EcoNet login info. When I enter it, I get the "No water heaters were found" error. This integration says it's for water heaters and thermostats, and I've got the latter. What am I missing? TIA.
I believe this does not yet support HVAC, only water heaters.
There is a local solution in home assistant for Rheem Econet hvac that involves flashing an esp32 or the like and connecting it to the furnace data port. This is what I’ve done and it is rock solid.
Once you have it connected to Home assistant, I understand you can bring it into HE via home assistant device bridge (HADB). I have not taken this step.

Ouch. The (apparent) Hubitat support was one factor in choosing this furnace over others that would have allowed us to keep our Nest thermostat. I assumed (I know, I know) that since the name of the integration mentions thermostats even before water heaters that it would, you know, support thermostats. Seems like the name of the integration should be changed. 
At any rate, thanks for the info. Not sure I want to get into HA just for this, but since the thermostat doesn't support additional wireless sensors, I may have no choice if we want to keep doing what we'd done for many years with the Nest. Appreciate the response!
