Tangental question - does the Rheem app for you show per hour consumption?I likely have the gen 5, it's 72 dBM right at the top when the compressor is running. water heater is in the garage and I can hear it making a constant sharp sound in the living room after showering. fortunately the compressor doesn't run the whole day so it's ok. but I am looking to get some sound dampening foam from amazon that will hopefully help.
Mine generally shows zero usage every other hour, and 2x what I'd expect on the others. There are rarer times it will show usage during adjacent hours though.
It's not a huge deal since the daily total seems to be correct, but we're all about accurate data here.
