Make it clearer to user when no radar images are available for enhanced and Mosaic styles

[jsiemonski]

I upgraded from 0.4.0 today, and seem to just have a black screen.

0.4.0 had a fatal bug, with was fixed in 0.4.1. Are you sure your are on 0.4.1 and restarted your home assistant? Which radar style are you using? Have you checked whether the radar is online on the website?

[MatthewFlamm]

Also are there any errors in your logs?

[jsiemonski]

I will check the logs when I get a chance.

Looks okay on my system using standard style, although you've got some serious storms.

I have it in Enhanced, does that matter? I’ll try a reboot when I get home.

This is not a problem with the new version.
There are no radar files available right now, see below where there would be a list of images normally. I'm thinking that either an error should be logged or the entity should be marked unavailable, or both. Or maybe instead of being black, it shows 'radar not available'.

On a positive side, the NWS website shows no storms in the enhanced view while my package makes it black in this case.

I'm going to keep this open until there is better error handling after I think about the best way.

Whew.. just happened to coincide with my upgrade. Thanks for checking it out! I was just digging through my logs..

I'm also noticing the standard style I posted is showing a radar from 12 hours before I loaded it. NWS website shows the same. I should also check the times to avoid using stale images (this will only work for enhanced style probably).
