Heat pump
Vaillant + Therilly
Coming soon: spot-price control of Vaillant aroTHERM and geoTHERM with AI.
Therilly is developing an integration with myVAILLANT and sensoNET via Home Assistant. Once ready, we control your aroTHERM plus, flexoTHERM or geoTHERM based on the electricity price — heating and hot water are charged during the cheapest spot-price hours and we use the weather forecast to preheat the home before prices peak. The result is an estimated 15-30 percent saving while indoor comfort stays the same. The feature is not live yet; join the queue and we will reach out at launch.

Frequently asked questions
- How do I connect Vaillant to Therilly?
- Join the waitlist and select Vaillant as your heat pump. We will contact you when the myVAILLANT / sensoNET and Home Assistant integration is ready. At launch, sign in with your myVAILLANT account and enable Therilly control.
- 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.
