Live Diagnostics shows what each outdoor unit is reporting right now: ambient, compressor frequency, discharge, condensing and suction temperatures, high and low pressure, expansion valve position and power draw, with every indoor unit's temperature against its setpoint underneath.
Pick an outdoor unit and Nexus iQ draws its refrigerant circuit: compressor, condenser, expansion valve and evaporator, with the live temperature at each point and the pipe colour following what it carries. Lift, discharge superheat, superheat and subcool are calculated from what the unit reports. Anything the unit does not report is left blank, not guessed.
Per-unit telemetryAmbient, Hz, discharge, condensing, suction, HP, LP, EEV and watts on one row per outdoor unit

The list view is the service tool that never gets unplugged: one row per outdoor unit with the nine live readings, the brand and address, and how long ago it last reported.
