Websitechecker

Custom integration that checks if a website is reachable or not.

A website is considered OK when an HTTP request returned with a response code < 500. Or the other way around it is considered a problem if the HTTP request failed or returned a response code >= 500.

The sensor offers the following additional attributes:

• url: The configured URL for this sensor
• last_status: Status of last update. Some possible values are "200 - OK" or "Connection error". More error values exist.
• last_error_status: Status of last error, allows to easily see what the last issue was if it came back already.
