What people report

Pax Calima, Levante and Vent-Axia Svara/Svensa fans work over Bluetooth; a socket/file-descriptor leak crashed some HA hosts in 2026.

Device	In Home Assistant	What they said	Source
Pax Levante 50	Works Local	Bluetooth auto-discovery and PIN discovery added Saved copy Improves support for Pax Levante fans: - Add bluetooth auto-discovery for Pax Levante, alongside PAX Calima - Auto-discover the Levante PIN during setup if the fan was recently power cycled - Show the discovered device name in the Bluetooth discovery card The code has been tested in an environment with a mixture of Calima and Levante fans. Both bluetooth and PIN auto-discovery are probably generalizable to Svensa fans, but as I don't have any of those to test on, I limited added auto-discovery support to Levante for now. Note that some of this code is authored with Claude Code but I have … Excerpt saved from GitHub on 2026-10-23.	PR #97 · 2026-02
Vent-Axia Svara	Works Local	Calima-compatible; no air-quality sensor Saved copy Supported devices: Pax Calima (Nordic naming scheme); Pax Levante 50; Vent-Axia Svara (Calima-compatible, no air-quality sensor, UK(+) name scheme); Vent-Axia Svensa (PureAir Sense model family).

Vent-Axia Svensa	Works Local	Supported; pause function added Saved copy Pause is an useful manual function in my Svensa fan. It has a time in minutes as argument - the app has 30-120 min with 30 min intervals (but in practice you could write any byte). While pause is active, the same argument read yields the pause time remaining. While I was at it I fixed an issue with reading of `TimerFunctions` to config data. Thank you so much for this integration! I can finally ditch the official app :stuck_out_tongue_winking_eye: Excerpt saved from GitHub on 2026-10-23.	PR #74 · 2025-07
