Hi all,
I’m working on a client project involving a Harvia WiFi sauna system and I’m looking for guidance from developers who may have worked with similar smart device integrations.
Goal of the Project
We need to connect Wix Bookings to a Harvia Xenio CX170XW sauna controller, so that:
Whenever a customer books a session through Wix Bookings
The sauna automatically starts heating 30 minutes before the session begins
This is a developer-level task, and we know that Harvia provides an API for this controller model.
Device Info
-
Sauna: Harvia Xenio CX170XW (WiFi-enabled)
-
Product page: https://www.harvia.com/en/products/CX1704XW/xenio-cx170xw-wifi-black
-
API access:
Confirmed
What We’re Exploring
-
Has anyone integrated Harvia’s API with custom web apps or smart systems?
-
Can the Wix Bookings backend (via Velo) be used to schedule API calls 30 minutes before booking start?
If you’ve done something similar or have worked with Harvia’s API, I’d love to hear how you approached it.
If you’re open to it, I’d be happy to connect you directly with the client so you can discuss the technical implementation further.
Thanks in advance!
