I did some development but it has been "on ice" for over a year. The idea was to offer something running in the "cloud" for quick testing and sharing sensor readings with friends and family. But (as always) it quickly grow out of proportion (storing historic data, dashboards, mail triggers etc) and I realised other projects does this much better. I.e. a hosted NodeRED would do the trick (e.g. https://fred.sensetecnic.com/).
Another issue would also be how to handle the hosting cost for the service (which would require a few more cpu cycles and storage than the current site).
Not sure what will happen with the code, it was pretty tied to the main site with users etc. Maybe I will pick up the work some rainy day.
