I was able to get a simple example of turning the stick LED on and off with a slider switch. You need to alter the coordinates and size of the qr in order to make it visible on the screen [image: 1583288007416-screen-shot-2020-03-04-at-13.11.55.png] Response is a little slow though, you may want to try IFTT or try to use http request and control from the browser or make an app with mit app inventor, I made a guide here a while ago, It's using arduino but I hope to do an updated version once I get an android phone. https://www.hackster.io/lukasmaximus89/m5stack-and-mit-app-inventor-47bd32

I have a few related questions. All are related to charging the M5StickC, JoyC and RoverC and their drain during use. Given that RoverC and JoyC need an M5Stick to be connected to be charged and all have the devices have batteries in them and the batteries in each set (M5StickC paired with either JoyC or RoverC) differ in capacity. How Do We know: State of Charge of the batteries in either set? When To disconnect the charger? (batteries fully charged) and Which of the two batteries in each set is being drained during use( M5Stick's or Hat's)?
