This is a design mockup. Every reading on this page is invented to illustrate the target build. Nothing here is connected to a live device, and no Home Assistant data is ingested or displayed. The live platform is deployed and healthy — this page shows where it is going, not what it currently measures.

Energy

Current draw by circuit

Watts, live from the smart panel. The EV charger alone is more than every other circuit combined.

Whole-home power, last 24 hours

Evening peak is EV charging stacked on top of HVAC — the exact overlap that shifting to off-peak eliminates.

Naming convention

<domain>.<area>_<device>[_<measurement>]

Area first, so entities sort and group by physical location. No vendor names, no abbreviations, no indexes that change when a device is re-paired. Every entity on this page follows it — which is what makes "energy by area, last 30 days" a GROUP BY instead of a hand-maintained list.

UseNotWhy
sensor.pool_water_temperaturesensor.pool_temp_2No abbreviations, no vendor counter
light.kitchen_islandlight.hue_color_lamp_3Vendor name and meaningless index
lock.front_doorlock.august_lock_frontIntegration leaks into the ID
binary_sensor.garage_bay_1_doorbinary_sensor.garage_door_aNumbered instances use digits

Why go all in

One brain, not twelve apps

Pool, HVAC, locks, irrigation, EV, and media answer to a single system. No vendor cloud is required for anything to work, and nothing stops working when a company sunsets an app.

Energy that pays for itself

Circuit-level metering shows exactly what draws power. EV charging and pool filtration shift to solar surplus and off-peak windows automatically — the two largest controllable loads in the house.

Failures caught early

Rising filter pressure, a leak sensor going wet, a freezer drifting warm, an attic at 104°F — each is a notification minutes after it starts rather than a discovery weeks later.

Local and private

Automations run on the home network and keep running if the internet drops. Cameras and presence data never leave the property unless explicitly sent.

History that answers questions

Every state change is retained, so "what did the pool cost to run in August" and "how often did the gate open last month" become queries instead of guesses.

It compounds

Each device added is usable by every automation already built. The fiftieth device is more valuable than the fifth because the surface it can react to has grown with it.
