Hi, I am trying to achieve this as well.
The idea is to collect data at specific intervals during device awake/sleep cycles, and when enough data is collected, power up the wifi module and send the whole array to thinger. Rinse and repeat.
Hoping to maximize battery lifetime with this technique.
Also I will be writing a custom PC app for data visualisation, so that I'm not limited to thinger's widgets using single values.
Hope you can provide some links to documentation that can help me achieve this.
Thanks in advance!
