Re: SD card copying problem rpi3

Well Jessie does not have the SD card copier if I remember correctly , so your only option is to shrink your existing image file using a Linux desktop pc and the script I posted then you can write the image to your new card and expand it. Raspbian Jessie was released in September 2015. The SD Card ...

Re: Setting up gpio using classes

It isn't necessarily the 'correct' (ie. mandatory or only) way, but it would be worth looking at how the gpiozero python library module is implemented.

Re: Etcher or Win32DiskImager

The installation guide on the official website for Raspbian says it recommends Etcher, but I noticed that the program doesn't have a backup function to back up your hard drive unlike Win32DiskImager does. Raspbian has its own backup utility, SD Card Copier . But it's your system, your choice. Use w...

From the Notes section of the document you have linked to - This has been tested on Raspbery Pi 3 and Raspberry Pi Zero.

Re: Humidity

Do you have, or can you borrow, any independent means of measuring the humidity close to where your weather station sensors are installed?

Maybe you have a micro-climate in which the reported results are accurate even though unexpected?

WiFi.

It's built in to an RPi 3b.

If it isn't built in to the laptop, use a usb WiFi dongle.

The pi is a complex piece of hardware. Each pi is somewhat unique. Each RPi is, for practical purposes, unique by virtue of its hardware encoded serial number. But that's all.
