What if my heat pump brand isn't supported yet?

Alva Link supports the vast majority of European heat pumps through multiple connection methods. Even if your specific model doesn't have a native Modbus integration at launch, Alva Link offers multiple fallback paths: OpenTherm for thermostat-bus systems, SG-Ready for the universal four-mode standard (500+ certified models), and outdoor temperature sensor spoofing for legacy units with no digital interface. All run locally and are included in Essential (free).

We're expanding native integrations continuously through firmware updates. If your brand isn't on the list today, it may be tomorrow — and your Link will gain that capability automatically, no hardware change required.

Check the compatibility page on our website for the current list, or reach out to us directly. If you're one of our Founding Members, you have a direct line to the team.
