Two homes. One evolving intelligence. Start with real-world questions, test them safely in simulation, and prepare for your new home.
1 kW IRSun infrared panel, gas-fed radiator, Samsung TV, Sonos Arc Ultra, Biscuit sleeps downstairs. Actual temperature/energy telemetry not yet connected.
A2-rated 3-bed new build, air-to-water heat pump, downstairs UFH, planned AC, Siemens/Bosch appliances and possible solar, battery and EV systems.
Change assumptions to test costs. Duty cycle is a hypothetical percentage of time heating at rated power, not a measurement.
Editable illustrative daily energy budget. Heat pump energy is electricity input, not heat delivered. These are assumptions, not predicted bills.
Hourly demand and tariff windows → weather-based heat pump performance → appliance cycle profiles → solar generation → battery state-of-charge → EV charging deadlines. Each module will be validated before being treated as a decision tool.
Voice uses your browser’s speech services when supported. Tap Speak and grant microphone permission. It is not always listening.
No cloud AI or live device control in v0.8. Responses use simple rules and stored settings. Messages remain in this browser unless you export data.
Test natural-language lighting scenes before buying bulbs. These controls do not switch real lights. A future Home Assistant connection will require verified devices and secure server-side access.
Say “make it cosier”, “a little brighter”, “too dark”, “movie mode”, “back to normal”, or “perfect, save this as Cosy”. Saved scenes are stored on this browser only in this pilot.
Real bulb capabilities differ. This simulation uses 2200–6500K; it does not guarantee your chosen bulb can reach those temperatures.
For live control we will use Home Assistant's light entities, scenes, verified bulb capabilities and a secure backend. No token belongs in this public web page.
Structured, explainable investigation. Uses your assumptions, not real heater telemetry. No AI API or device control.
Enter an observation and run the investigation.
Planning records, not proof of installation or compatibility. Verify model numbers and manufacturer specifications before modelling power use.
Update checks require HTTPS hosting. Local HTML cannot update itself automatically.
The offline cache stores application files, not a server copy of your personal data. Clearing browser storage can erase local preferences unless backed up.
Opt-in cloud storage. Existing phone data stays untouched until you choose an action. This is a whole-household snapshot, not automatic multi-device merging. v0.6 watches for newer cloud revisions and warns you without overwriting local data.
Sign in to check cloud setup.
Cloud change watcher is not running yet.
Export a JSON backup before either action. If two people edit separately, a conflict will block the second upload. Do not use cloud sync for sensitive information until access has been checked.
Saved locally in this browser, with optional manual cloud snapshot sync. Export backups before replacing data.
