Hi, Im building a system to read temperature with the Photon in remote areas where I dont have power supply, so I will buy the Sparkfun Battery Shield, battery and Solar Panel for my Photon.
The Question here is, the battery is always charging when it is sunny day? or it will only charges when the battery is low voltage?
My project need to be working 1 year with no battery change, so I will develop the program to only wake up the Photon once every 15 minutes to read temperature in the day and sleep all night. Also is there a way to wake up the Photon via wifi? I want to read the temperature with my Mobile using an app Im developing, so maybe open the app and wake up the photon only when the app is running.
Can anyone help me with this?
Is it possible to do it?
