I use a "Flo by Moen". It has some community support, but I just let it do it's thing and notify me if there are issues. I do not have it integrated into HE at this point. It does have some nice readings internally, and IFTT support for integration if required.
After installing a warrantee replacement unit, thinking the 1st unit was faulty, I can tell you over tightening the unit will stop the 'turbine' from spinning and not give you GPM readings. Do not over tightening.
