Recently downloaded the phyphox from F-Droid and thought about this while thinking about what all stuff I could do with it.
Are there any online resources about such stuff?
What all things have you(or people you know, in your locality etc) done along that line?
And not only big thigs, if you’re tracking other stuff, please do share your experience on that too.
Edit:
Sharing the github page of the app too:

I build an off-grid solar power set on my back yard and tracked it’s results for two years. It was only 500W in 3 directions (east, south and west)
It first charged the batteries and then used the rest to heat water if no direct use was present.
Learned a lot and noticed that many ideas and mental images about it were bullshit. Still usefull if applied to right applications.
Not gonna buy a bigger set and will use the existing ones to just heat water till they give up.
What kind of heating element did you use for the water? What type of control system to send power to it?
I’m using 220V/6kW heating element. When used with 60VDC directly from the panels, it’s about 0,45kW. No need for control system, since that is too weak to bring the water to boil. It’s function is just to decrease the consumption of heating oil. Oil burner is set to start at eavening just before enyone needs hot water and panel output goes down. Oil burner heats the water in the tank to 80ºC. It’s about 40-60ºC next morning when the sun rises, depending on the consumption.
Care to elaborate on the bullshit?
Thank you.
What were the main ones?
Some relatives of mine have been thinking about rooftop solar and had talked about it to me too. Didn’t comment much, other than generic talking points of warranty, on whether is on or off-grid etc.
