Today I've charged during rain and used OpenLog to record data. The charger captured 2Ah during 10 hours charging. I've made a utility for managing plotly files easily. It's called log2plotly and it automatically adds date and time to all measurements, it also allows for manipulation of custom measurements such as GA1A12S202. I've not yet figured out how to calibrate and use the light sensor reliable. During this measurement I left it fully exposed to the rain ( which might explain some strange values ). I'll include log2plotly with source code (upcoming ver 0.95).
