+"""Host probe v8 — household wattage via the business operations API.
 
-Three socket APIs: realtime detail (home-page poll) -> ``totalPower``,
-per-switch load status -> ``SWxExpPower``, EMS telemetry -> watts math.
+One call per port: ``LocalDeviceClient.get_household_wattage`` (realtime
+detail → per-switch load → EMS math). Prints the watts.
