Export to csv from the History Graph works beautifully. If this could be invoked from the hardware side with a specified time range, that would make it ideal!
I love the idea of pushing the data off of your server to other locations for the sake of keeping you total stored data (and therefore operating costs) minimal.
I know you probably would prefer it to get pushed through the app, because then folks need to purchase the history graph widget to accomplish this (and I totally understand that), but I am guessing you guys could figure out how to filter export requests from the hardware side that only works for the history-graphed data… or maybe it is worth it to you to just make it accessible to all data on your server for free… or perhaps a new widget, similar to ‘push notification’ or ‘email’, that would allow the export of any data collected in the project in the previous month that has been written to the blynk server. It is invoked from the hardware, but only works after installing the ‘export’ widget in the app.
