Feature Request: If IP is unreachable, reduce poll frequency

[madtempest]

Is your feature request related to a problem? Please describe:
I have the GW10KAU-DT model which shuts down when it is not generating, causing the wifi module to go offline, however the plugin spams the logs of Homebridge with "new value = -1" forever until the device returns to generating and reconnects to the network.

Describe the solution you'd like:
Add logic to the plugin that checks for the IP being live before it polls for data. If the IP is not live, do not attempt to poll again for say, 1 hour OR allow the plugin to gather weather data/sunrise time from a source within Homebridge such as https://github.com/naofireblade/homebridge-weather-plus#readme

Describe alternatives you've considered:
None, new to this plugin.

Additional context:
I'm still waiting to confirm that the device shutting down when it's not generating is normal.

Thank you for your suggestion, there is some backoff strategy, but this is indeed flooding the logs still. I will put it on the roadmap.

PS. Polling will probably still happen on the background because you will never know when the device will become available again the the morning when the sun gets up.

Thank you!

On the topic of the sun, that's why I was suggesting some kind of integration that can read expected sunrise from a weather forecast service perhaps, so that the plugin can "estimate," a clock time to start ramping up polling again.
