Yes we are aware of the issue and have been working to switch weather data provider (to openweathermap). Samer has finished the coding part and we are doing final testing. Should be done in a few days.
@smgustafson: the update is already done — this does not require any firmware update, it’s just a change on the opensprinkler weather server. We’ve updated the weather script to automatically use OWM API if no WU key is provided, and WU API if the key is provided.
