Every server is a separate entity… API is probably the only possible way for the aforementioned messy and cloogy way of trying to share data. In fact, I have never even tried it so don’t even know if it is possible. EDIT - Yup… I just forgot - [SOLVED] Connection between the cloud server and the local server However it will still be only a one way link as you apparently cannot open up your Local Server properly to receive WAN sourced data.
Perhaps just setup your Local Server in another location without all the router issues… or even on a paid for cloud service… yes, more $$, but Local Server still gives you full control over everything, including energy.
