Heat pump
Fujitsu + Therilly
Coming soon: spot-price control of Fujitsu Waterstage via FGLair.
Therilly is building an integration via the FGLair app and Home Assistant. The idea is for our AI to shift heating and hot water on your Fujitsu Waterstage air-to-water pump and your Fujitsu General air-source units to the cheapest spot-price hours, and to preheat the house ahead of expensive hours using the weather forecast — typically 15–30 percent lower electricity cost with no drop in comfort. This feature is planned and not available yet.

Frequently asked questions
- How do I connect Fujitsu to Therilly?
- Join the waitlist and we will notify you when Fujitsu support opens. At launch you connect your FGLair account or Home Assistant to Therilly. Set your comfort level and Therilly’s AI optimises heating and hot water against the spot price.
- Do I need to install any hardware?
- Usually not. If you already have a power meter like Tibber Pulse, Shelly EM or HomeWizard P1, signing in to Therilly is enough. If you don’t have a meter, we recommend HomeWizard P1 which requires no electrician.
- Can I control the pump myself any time?
- Yes. You can pause Therilly at any time and take back full manual control via the pump’s normal app. Therilly does not take over — it sits on top.
- How is the heat pump connected?
- Depending on model, either directly via the manufacturer cloud (Qvantum, Mitsubishi MELCloud) or via Home Assistant or Homey Pro. The connection takes 2–5 minutes and only requires that you sign in with your existing account.
