Re: Is from PC usb port OK for power supply?

Electrically a PSU that is specced for a RPi3 will probably be adequate to power a RPi4B with mouse and standard keyboard. But how can you connect the micro-USB plug of the PSU to a RPI4B? I can't, that is why I asked about PC usb or phone charger. I think I will wait for the proper power supply......

Re: Is from PC usb port OK for power supply?

Thank you but you haven't read my previous posts. I have already ordered the official pi 4 power supply. I asked if there is any alternative solution to power my new pi 4 till I get the official pi 4 power supply.

Re: Is from PC usb port OK for power supply?

Yes pi 4.
My phone charger says: 9V, 1.67A or 5V, 2A.
Could I do any damage if I use that for 1-2 days?

Thank you

Monitor temperature of different rooms

How can I read and monitor the temperature of different rooms or even refrigerators? Do I need 3rd party sensors and pair all of them with 1 Raspberry? Can they interact wireless? Could you please give me some clues what parts do I need and a basic plan or some similar project? Thank you!
