MX uses this library for weather stations (like Fine Offset and USB connected Oregon Scientific models) that appear as a HID via a USB connection. To check if your weather station appears as a HID, download this [https://cumulus.hosiene.co.uk/download/file.php?id=11414 USB HID test package] and run it.
 
 
This HidSharp library calls a package ''libudev shared library'' file called ''libudev.so.1''. Most recent Linux distributions will already include the libudev shared library. On my Raspberry Pi, [[#install|typing]] <code>apt search libudev</code> showed ''libudev.so.1'' was already installed. If it is missing, then [[#install]] it.
=Cumulus packages=
 
Note use of plural in section name above, the following sub-sections will install various packages produced by Developer Mark Crossley. If you are using the [[Software#Cumulus_MX|pre-built disc image]], then (unless the MX release version included in your image is an old one) you should skip the instructions for installing "CumulusMX" itself.
 
==Handling zip files==
*# The developer suggests you use ‘’’/opt’’’ for EXISTING PATH (which should be available on any Linux computer).
*#* By default, the code Mark provides for installing Cumulus as a service, will run that service as a root user, and the root user has full permissions in /opt (and everywhere else)
*#* (Novices: Skip this step) If you do choose a EXISTING PATH outside your home folder, youthen mighta wantmore totechnical user can change the ownership of the "CumulusMX" sub-folder, to the default user (Pi), if so, typewith <code>sudo chown -R pi: EXISTING PATH/CumulusMX</code>., and Thereduce advantagesthe ofneed thatto command is you no longer needuse "sudo" toon accessmany theactions. files (however, if you are running MX as a service, you also need to edit the user in the script provided to create the service, so MX does not create files with root ownership - this will be covered later)
 
==Packages to install==
 
This list of parameters covers every parameter, if you are using the latest release skip the historic 3.0.0 sub-sections.
 
IMPORTANT: The "sudo" prefix shown in code examples for the various parameters can be omitted if the user that is running MX owns the folder "CumulusMX" and all its contents. In the [[#Where to install all packages?|installation notes earlier]] possible locations and ownership issues were mentioned. That earlier section also defined EXISTING PATH, if that is not mentioned in the code examples, it is assumed you have already issued a <code>cd EXISTING PATH</code> to be in the right folder for issuing the command.
 
Note that you ''may'' need to supply your root password after typing any 'sudo ...' command line if the instruction changes something set by another package (e.g. changing the locale for MX from the locale set by mono). The system will prompt you for this if it is needed.
=== -port parameter for changing Port ===
 
When Cumulus starts, it will display the URL of the user interface. It runs on port 8998 by default; if this is not suitable for some reason you can over-ridechange it using the '-port' parameter on the command line, e.g. to use port 9999 instead:
<pre>sudo mono CumulusMX.exe -port 9999</pre>
 
=== -lang parameter for changing Locale ===
 
Individual computers may have different default for their locale. The forum reported an issue with OS X with its default US locale even if that is not your locale.
On Linux and (in particular) OS X, Cumulus MX may not be given the correct locale to use, and you may get the default US locale even if that is not your locale. It will output the local it is using when it starts; if it is not correct, close it down and start it again, this time specifying your locale on the command line, using the -lang parameter . For example, in the UK, on a non-Windows device type:
 
As MX starts its output (to diagnostic log and to any interactive terminal window) says which locale is being used, '''Current culture: English (United States)'''. That default locale will relate to the one your computer had when mono is installed, as it is mono that tells MX all the locale settings. If you notice MX starting with wrong locale, issue the correct instruction to close MX.
 
You can use a '''-lang''' parameter to change the locale as you restart MX. For example, in the UK, type:
:<code>sudo mono CumulusMX.exe -lang en-GB</code>
 
Other locale examples: '''CumulusMX.exe Current culture: English (United States)''', '''CumulusMX.exe -lang de-DE''', '''CumulusMX.exe -lang el-GR''' (this is one of the locales that reads numbers with '''integer,decimal''' format), '''CumulusMX.exe -lang nl-NL'''.
 
If you are not sure what value you need to supply for the -lang parameter, there is a list here - http://msdn.microsoft.com/en-gb/library/ee825488%28v=cs.20%29.aspx. You need to supply the code in the first column ("Language Culture Name") in that list.
 
There are some edits needed to that section:
# ReplaceTechnical users might want to edit the '''User=root''' ifline youso wantthat the service towill run as a different user, novice users are best to leave this alone
# EditEveryone must edit the line that begins with '''ExecStart='''
#* The mandatory change is to replace '''/home/install''' by what you have selected for EXISTING PATH
#* An optional change is to add additional parameters after the '''-service''' (select from '''-debug''', -locale, -port) as described in sub-sections above
# Next save file with a new name '''cumulusmx_minecumulusmx_edited.service''' (using a new name stops it being overwritten when we upgrade MX
#now Now copy file to where it is needed to run the service: <code>sudo cp EXISTING_PATH/CumulusMX/MXutils/linux/cumulusmx_edited.service /etc/systemd/system/cumulusmx.service</code>
# Finally, optionally create a symbolic link to that file using <code>sudo systemctl enable cumulusmx</code> if you want the service to start after a reboot
:<code>sudo cp EXISTING_PATH/CumulusMX/MXutils/linux/cumulusmx_mine.service /etc/systemd/system/cumulusmx.service</code>
 
Here is how the file might look after the changes:
