Six apps that don't talk to each other.
The inverter knows about the sun, the charger knows about the car, and the heat pump knows the house is cold. None of them know what the others are doing.
One board on the wall.
We connect everything to a small hub in your house and give it a face: a colour e-ink board that looks like a print and reads from across the room.
The detail is on your phone when you want it.

The house gets ready overnight.
While you sleep, the battery fills and the car charges, timed to suit your tariff. In the morning the board tells you it's done.

Warm before anyone's up.
When frost is forecast, the heat pump warms the house early. On mild mornings it leaves the house alone.

Watch the sun at work.
The board shows what your roof is making right now. On a good day it suggests putting the washing on, so it runs on your own power.

The bit your friends ask about.
What the roof made today, and how much of the house ran on it. It's on the wall, so it tends to come up at dinner.

Evenings run on your own power.
The battery is saved for the evening, so the busiest hours of the day come from your roof, not the grid.

When something needs attention, it says so.
If the inverter drops off the Wi-Fi or an app logs itself out, we get the alert and usually fix it remotely. The board tells you it's in hand.
You only hear from us when something needs you.

A short letter every month.
What the house made and used, what we changed, and anything worth knowing. In plain English, with honest numbers.
