RPi, Raspberry image backup to Mac

             Updated 2018-02-14 !

This backup method will make a copy/image of the whole card even if there is very little data on it. So if the card is 16Gb, the backup file also will be 16Gb. On the other hand You can ZIP the image file to save space.

Another, maybe smarter ?,  backup method is described here.

Connect the card reader, with the SD card inserted, to Your Mac.

Start the program Terminal, on Your Mac, and check Your SD cards name type.

$ diskutil list

and You will have something like

/dev/disk0 (internal, physical):                                              
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *121.3 GB   disk0     
   1:                        EFI EFI                     209.7 MB   disk0s1  
   2:          Apple_CoreStorage Macintosh HD            120.5 GB   disk0s2  
/dev/disk1 (internal, virtual):                                              
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:                            Macintosh HD           +120.1 GB   disk1    
                                 Logical Volume on disk0s2                  
/dev/disk2 (external, physical):

Weather34 install at WEB hotel

Updated 2018-06-19 !

Prerequisites is listed in the beginning of this post for installation on Raspberry Pi(RPi)

You will find a migration from WeatherLink 1.0 to WeatherLink 2.0 in this post

Hosted installation

In this guide I will use Loopia as an example but other hosts schould be similar

In our case we have created a subdomain which is used for the W34 application

In the root of the subdomain a folder, named "public_html" , is created by the host and this is the webserver document root.
