Good day dear friends, hello dear all at the forum,


here a question regarding the raspberry-pi power consumption - and optimize it with a battery/Photovoltaic supply!
I plan to use a Raspberry PI 4b powered by battery and hopefully.

use case i want to run a little weather-station outdoor: and it should send dataset each day.

some musings regarding the powerconsumption: well i think that i need to recharge the battery every few days and that is impractical.

Questrion: can you help me to find out more data - how to set up all - and how to take care that power consumption is under control.

the power-consumption: to get a overview - i can look at the datasheet. but the question is: how to learn more about the real power consumptoin:
that said: is it a good idea to monitor in real-time the power consumption of a RPi. Well, I know this can be done with a multimeter in ammeter mode in series, besides this method, I thought maybe there is even a easier method, directly from command-line?

the RPi by the way - has alot of electronic features, so maybe it has (allready) various sensors, including one for the electric current in Amperes? can we use this!?

Look forward to hear from you
