I am the original author of the geo_rss_events sensor, and I am currently in the process of rebuilding the foundation of this sensor.
Background is that the sensor currently uses a library that is not Python 3.7 compatible, and it does not look promising that it will be in the foreseeable future. So I decided to replace the library with new code that specifically focuses on parsing GeoRSS formatted feeds. I tested plenty of public GeoRSS feeds and have tried to cover all the edge cases I could find.
Now, to ensure that I am not breaking your existing configuration, could you please send me the feed URL you are using with the geo_rss_events sensor?
Thanks
