Why do I keep getting a "Homey Pro temperature" notification?

The notifications appear at random times and just say one word: “temperature”. I assume it’s telling me my Homey Pro is overheating? However, it’s on a desk in a shaded, well ventilated area, near a Netatmo weather station. Room temp is usually 17℃ and never exceeds 20℃.

My Homey Pro is quite new (2023), it’s not dusty, and I’ve only just started using it.
I have 24 apps, and 11 flows. No scripts.

Just the word “temperature” would be a very non-professional error message imho.

When the same notification isn’t mentioned at the timeline as well:
The only thing I can think of: there’s a forgotten (test) flow somehow, probably driven by a temperature sensor, and you added a Push notification action card with the word “temperature”.
(Hint: always add the flowname to notifications).

To find out: try the Homey “Audit” app, maybe it reveals the source of this push notification. It spits out (almost) every event.

OK thanks. I’ve installed the “Audit app” and connected to Betterstack.com via API, but I’m confused how to view the logs. I’m not a software engineer so Betterstack is quite overwhelming.
