Hello everyone, hope you are all in good health. I've been trying to work with water heater use side mass flow rate but had no luck. I have a simple WaterHeaterMixed. When using sensor in EMS, WATER HEATER_UNIT1,Water Use Equipment Hot Water Mass Flow Rate or node mass flow rate. I get an error of invalid output:variable. I've also tried with the following related nodes and still get the same outcome: DHW Supply Outlet Node_unit1 DHW Demand Inlet Node_unit1 Mains Inlet Node_unit1 Mains Makeup Node_unit1
Thanks !
