AttributeError: 'CrossTrainer' object has no attribute '_m_features'

Hello,

I'm using this library on a HomeAssistant Custom Component. It correctly detects my elliptical bike (BHTFT-0596) but after a while it times out showing next exception in the logs.

2025-10-12 16:18:44.521 ERROR (MainThread) [homeassistant] Error doing job: Task exception was never retrieved (None)

Please let me know if I can provide more details or how to increase debug level if needed.

Thanks for create this library, it is very useful.

I had the same issue with my Sole F65, this might be causes by the missing service data.

You could try out if #54 also fixes your issue.
