Describe the bug
I keep getting errors and warnings in my system log. I have two locations I’m monitoring. I downloaded the weather_alerts1.yaml and changed the name to the location I’m monitoring (Vilas.yaml) and did the same thing for the second location (Malta.yaml). I modified the sensor names in each file to corespondent to the weatheralerts sensor in HA (also renamed to the location) and get the errors below. I get them for both locations.
