I have a SunAirPlus (part of the SkyWeather kit) that I'm not sure is working right, or maybe this is by design? I have an external power source connected via USB, and a battery connected to the battery connector. My expectation was that the battery would get charged by the external power source, and if that source went away, then the battery would power the device until it was depleted or external power (or solar power) returned. However, it doesn't appear to be charging the battery. The battery is actually discharging while external power is supplied.
At this moment my load is reading 0.736 W, my battery is providing 0.443 W, with no solar power. So I guess it's pulling 0.293 W from the USB cord, for some reason. Why doesn't it pull more and charge the battery?
In addition, there doesn't appear to be a way to read the external power information from the device. There are only three "channels" used in the code in SkyWeather.py: LIPO_BATTERY_CHANNEL, SOLAR_CELL_CHANNEL, and OUTPUT_CHANNEL. Is there something hiding I could use?
Thanks!
