How Therilly works

Your heat pump works when power is cheap — and rests when it’s expensive

Therilly is an AI that controls your existing heat pump. You don’t replace hardware — you just add a brain.

How the data flows

Therilly pulls real-time data from several sources — upcoming spot prices, weather forecasts and more. What makes it unique is that it also gathers data from your own home to learn its thermal inertia. With that, the Therilly robot adapts your heat pump to heat during the most efficient hours and back off when prices spike — for maximum savings and lower energy use.

And this is how to get started

  1. 1

    Connect your heat pump

    Create an account in the app and connect your heat pump by signing in with the account you already use in its app: Qvantum direct, NIBE via myUplink, Mitsubishi via MELCloud or Daikin via ONECTA. For brands other than Qvantum, our support team sets up the control, usually within 1–3 days. More brands are on the way.

  2. 2

    Set a comfort floor

    Choose the lowest indoor temperature you accept (e.g. 20.5 °C). Therilly prioritises never going below it.

  3. 3

    Switch on the AI

    Therilly reads the spot price (Nord Pool), weather forecast (SMHI) and your home’s thermal inertia, shifting heating to the cheap hours.

  4. 4

    See the savings in-app

    Every day you get a report: how much you saved, how much CO₂ you avoided, how your pump performed in the cheapest hours.

Frequently asked questions

How often does Therilly update the heat pump?
Therilly reads the heat pump every 15 minutes and reviews the control every 30 minutes. The control follows a plan for the day, made hour by hour from the spot price and the home’s readings.
What is a "comfort floor"?
The comfort floor is the lowest indoor temperature you accept — for example 20.5 °C. Therilly prioritises holding that temperature at all times, even while shifting heating between expensive and cheap hours.
How does Therilly learn my home?
Within 5–10 days Therilly observes how fast the house loses heat when the pump pauses and how quickly it recovers. It builds a thermal model unique to your house, then uses it in every future optimisation.
What happens if the internet goes down?
The heat pump falls back to its built-in normal mode within minutes. Therilly is never a critical component — if the system can’t reach the pump, the pump runs as usual.
Does smart control wear out the heat pump?
No. Modern AI control avoids short compressor start/stops. Pauses are done by gradually lowering setpoints rather than hard cutoffs, so wear is equal to or lower than normal operation.
