See instructions here for info on how to set up a Blynk app to monitor multiple devices like this, including exporting data, etc.

I've set this up to have a home-screen that tracks total interaction time on both sippers (currently only showing one device but the idea is to monitor many of these at once. For each device we're tracking total interaction time on each sipper, as well as battery voltage.  I'll re-post screenshots when I have more devices online!

If you want to follow along, here's the QR for the Blynk app!
