From the box to the wall
How it works
A panel on your wall, your own devices, and as little of us as possible. Four stages, from ordering to knowing where the money is going — and what never leaves your house along the way.
Stage one · Before it arrives
Your account exists before the panel does
The moment you order, you have an account and an account reference — the thing you quote if you ever ring us. While the panel is on its way, sign in and update your account with your current electricity and gas supplier and the tariff you are on. It then arrives already knowing what a kilowatt hour costs in your house, so from the first evening it can tell you what your home is costing — in pounds, not just kilowatt hours.
It arrives knowing whose it is
Your panel is recorded against your account when it is dispatched. You plug it in, connect it to your Wi-Fi, and it finds the rest on its own. No code to scan, nothing to type, and no account to create on the wall.
Stage two · The first day
It starts watching the moment it is switched on
From the first hour, the panel keeps a record of how your home behaves: the temperature in each room, what your devices are doing, how much energy you use, when the heating runs, when doors and windows open, whether anyone is home, and whether its own sensors are still reporting. It is not making suggestions yet — it is building a picture of your house. That picture never leaves the panel, and if you switch learning off it is deleted, in one press.
Every house is different, so it learns yours
How long a room takes to warm up depends on your walls, your windows and your boiler, so there is no general answer — only the one measured in your house. Larunda measures it, and uses nothing else. The longer it watches, the better it knows your home, and nothing it has learned is ever discarded.
Stage three · Every day after
It suggests before it acts
To begin with, Larunda only makes suggestions. It tells you what it would have done — start the heating at 06:07, say — and why, and it does not touch anything. When you have watched it long enough to trust a suggestion, you can let it act on that one thing, within limits you set. Everything else stays a suggestion until you say otherwise.
You are always in charge
If you press a button on the wall, that is what happens. Larunda does what you asked and leaves the heating alone for the next two hours, so it never undoes a decision you have just made.
It tells us if something on it has broken — and nothing else
Four times a day the panel reports two things to us: that it is still learning, and any fault it has found with its own equipment, such as a sensor that has stopped reporting.
Stage four · If things go wrong
If the panel fails, your home is not gone
Every night Larunda saves a secure backup of your home — your rooms, schedules, paired devices and everything it has learned. The backup is encrypted on the panel before it leaves, with a key only you hold. If your panel ever needs replacing, the new one restores everything from it.
Updates cannot break it
Larunda updates itself automatically. If an update ever fails, the panel goes back to the previous version on its own, and your heating keeps running throughout.
What works with it
Your devices
Smart sensors, plugs and bulbs you may already have — anything that uses Zigbee, the wireless standard most of them use. They connect straight to the panel, with no hub and no account with the manufacturer.
Your electricity
Read from your smart meter through a small device called a Hildebrand Glow that sits next to the meter, or from a clip-on energy monitor.
Your heating
Controlled through a simple switch wired to your boiler, which Larunda operates directly. That is why your heating keeps working when the internet does not: there is no thermostat company in between.
Not every device works. If yours matters to you, ask us before you buy rather than after.
