ValueError: 'generator' is not a valid MeterType

I've been using this library via home-assistant for a year and it's great!

I recently upgraded to home-assistant 2021.10.6, which uses tesla_powerwall==0.3.11 and I am getting an exception when I attempt to communicate with the gateway:

Traceback (most recent call last):

ValueError: 'generator' is not a valid MeterType

My powerwall firmware version is 21.35.0, and I do have a generator power source.

Let me know if there's any more information I can provide, I am conversant in python, although short on time. I might be able to work on a fix myself in the next few days.

Thanks for reporting! It is a very simple error, as generator is not an expected meter. I will fix it immediately and publish the changes to home assistant.

Thank you! Let me know if there's anything I can help with in the future.

Sure, thanks!
