Problem running from console on raspberry pi

[Yersi88]

Hi thanks for the script it works great through jupyter notebook on my PC.

However, I would like to run this on my raspberry pi with Home Assistant. When I try to run it in terminal I get it to connect to WalkingPad but I'm unable to start it or do anything beyond that. It gives this error:

Thanks for the report. I will take a look.

[Yersi88]

Many thanks,

Maybe it's just something dumb that I'm doing.. I would like to get it working on raspberry so that I can eventually make Home Assistant integration :)

[ph4r05]

@Yersi88 could you pls try the newest master ed211c676c994092c925ae51adfe268affdd1e97? I could not replicate this on my rasp. Thanks!

[ph4r05]

@Yersi88 I've released a new version fixing other problems. Pls give it a try. I am closing this issue due to innactivity, if it happens again, pls reopen.

[Yersi88]

Hello, I finally had time to play with this again. I installed with pip on my raspberry with home assistant and it does work just fine now!

I would like to make custom HA integration, hopefully I will be able to pull it off, should be doable with your pip package :)

Many thanks!

@Yersi88 if you want testers for that, I'd love to help out!
