Do you do any simple experiments? Or track things and analyse them? (lemmy.sdf.org)

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:

At first yes, and I was planning to put raspberry + HAL-sensor + relay to handle the switch when average current to the batteries lowered, but to my surprise batteries charged enough with both connected. Battery charge controller is right next to the panels and there is some distance to the heating element. It appears that the MPPT battery charge controller so much lower resistance path that the current favors it.

My test setup only has 300Ah of battery, capacity at 12V, so it's charged quite quickly. Battery power only runs living room devices 50" TV, monitor, laptop, steamdeck, cable modem that are used about 4-6h a day and rarely on at the same time.

If it's a hot summers day, I might manually direct all to AC

... or if there's some catastrophic blackout during winter I can connect batteries to a radiator water circulation pump and heat the home by burning wood. This is very improbable, but at least there's something.

That sounds awesome. There seems to be a bit of a gulf in investment between getting a few panels to charge a backup battery or run some devices while camping, and actually doing a proper home integration. I'm in the midst of that gulf where I can generate more than I can easily store and use later, so I'd like to find some worthwhile uses for direct use of solar energy.

Don't know if you've seen it before, but here's an interesting article about direct solar.
