YET another take on an alarm system

Hi

I’ve decided to try this alarm panel as it seems way more advanced than the basic one, however I’m running into a problem that I haven’t seen while browsing / searching the thread…

At first I was getting an error about the custom component not being found, so as a couple people suggested I rebooted my server. From that moment, the HA service doesn’t seem to start properly anymore - the page won’t load, and I also have the Mycroft AI on another machine accessing HA through the API, it tells me it can’t find the HA server…
I have to remove / rename the custom_components folder in order for HA to work again.

Any ideas? HA’s log is of no help, and I couldn’t identify anything in the system log either…

Thanks.

PS: of course I have the Javascript instruction in my config file, however it it doesn’t seem to be the problem as the server can’t be reached at all.
