Hi Ben,
Netro sever side gets/updates weather information every early morning at 4 am. If the default weather provider doesn't work for you, you could try other weather source in settings->controller->weather provider. Please let us know if it works.
Thanks,
Netro Support
Netro updates weather information automatically after you switch the weather provider. Could you please refresh the page again if there is no change? You can choose the most suitable weather provider accordingly.
If the weather providers do not work for you, you can choose wunderground PWS station. However, there is a bug in our app. You can tell us the station ID and we can setup the station ID for you.
Thanks,
Netro Support
It is the time zone in your local area. Normally it's at 4am and the time is not fixed.
Thanks,
