Bypass Weather Sensor if Unavailable

[jamesonuk]

What is the feature?

Allow BT to ignore a missing weather sensor

Description

Currently if your weather sensor goes offline (Accuweather only allows 50 API calls a day and sometimes if you restart HA several times you can blow this limit and end up with a Weather sensor with a state of None).

If this happens then BT does not initialise and the logs just contain

Whilst the weather is a nice to have I think BT should not stop if it cannot get weather sensor

Additional Information

Similar to #1383 but more specific

Same here: the batteries in my weather sensor ran out, and the BT stopped working—despite having configured a weather service as a fallback that could have been used.
