Hi I just got a new hybrid Rheem Platimun Premium ProTerra hot water heater and HA integration is working but the available hot water metric appears to be inaccurate.
The mobile econet app shows hot water availability as 100% and I have to restart HA in order for it to pick it up again… very strange.
Bump…? Anyone have any ideas?
Stumbled across this looking for something else.
This is not an issue with the integration. It is an issue with Rheem. They have done a very strange method of interpreting how much hot water is left by doing a 4-state encoder. 100%, 40%, 10% and 0%.
There are no other values available. It would require Rheem to expose the temp at the top and bottom of the tank to the API to do anything beyond use what they provide.
it seems to be better now - but yea I wish there was more granularity to the temp monitors. looks like it only has 4 sensors?
There are just two sensors. Top and bottom water temp. They have some sort of algorithm that compares those temps and calculates the percentage. The output of that algorithm is the 4 states.
As to the high demand mode - I can’t say as I almost never use it. I have a hot water mixing valve so I keep my tank at 130-140F depending on time of day. For a family of 5 with showers and laundry my compressor does 98% of the heating. In the evening with high usage and cold groundwater, I do get short spikes of element use with balanced mode. The upper element can dump a lot of BTUs pretty quickly and I’m sure there is an optimizing routine that only heats the water enough to let the compressor catch up.
Here is a one hour period where we had a load of laundry, a shower and a tub drawn last night. You can see I had several short bursts while the compressor ran the whole time. The 6 seconds might have been right on the edge of when the element was needed.

Ok well one last question - not sure why it’s throwing this error in my logs as it appears to be working as expected…? just ignore?
Strange - i don’t get that at all.
Have you tried deleting the integration and re-adding it?
