I am new to Hass (playing with it for around a month off and on) and am working with a Hassbian installation on my RPi3. I installed the Weather Underground component based on one of the tutorial videos I found on YouTube. I was able to add all of the different sensors I saw successfully. After deciding which ones I actually wanted to keep track of, I deleted the ones I didn’t want. Now I have the correct ones updating but the old ones that don’t need to be included still show up. I now have around a dozen yellow circles with a triangle and a name “error” under them.
I’ve read that I can use database commands to purge the data I don’t want. That is certainly an option. Since I haven’t done much yet, I suppose I could probably even delete the existing database and just let Hass figure it out. Maybe even reinstall with the new config file. However, I don’t want to do that every time I have an unwanted module/sensor obviously.
What is the best practice for purging old components/modules/sensors that are not currently valid? This is what I found for manually fixing the database:
