How to install required programs for weewx on a Synology ds209+ii NAS

[Lucas Heijst]

To all Synology users: 

The synology (ds209+ii) NAS has a python 2.7 package. I was not able to get the required packages for weewx installed without getting compilation errors.

At last I found a way to install everything succesfully including proper system logging and an automatic startup of weewx after a system boot.

Note: The description below starts with a backup of an earlier installed weewx version. You can skip the backup and restore actions when you install weewx for the first time.

Luc

# note: the actions below are done in a putty session with user root

# delete old ipkg installation (not weewx)

rm -rf /volume1/@optware

rm -rf /usr/lib/ipkg

# backup current weewx version (in /home/weewx)

# note: I made a share "linux" on my disk station on volume 1. This share can be seen from Windows via a network share to 'linux', e,g. t:/0/weewx

mkdir /home

cp -rf /volume1/linux/0/weewx  /home/

# install ipkg

cd /volume1/linux/0

wget http://ipkg.nslu2-linux.org/feeds/optware/syno-e500/cross/unstable/syno-e500-bootstrap_1.2-7_powerpc.xsh

ipkg install py26-setuptools

ipkg install mysql

# notes during installation:

To start mysqld at boot time you have to copy support-files/mysql.server

to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !

To do so, start the server, then issue the following commands:

/opt/bin/mysqladmin -u root password 'new-password'

/opt/bin/mysqladmin -u root -h ds-luc3 password 'new-password'

See the manual for more instructions.

You can start the MySQL daemon with:

cd /opt ; /opt/bin/mysqld_safe &

You can test the MySQL daemon with the benchmarks in the 'sql-bench' directory:

cd sql-bench ; perl run-all-tests

mysql - 4.1.22-3 - Popular free SQL database system

ipkg install py26-mysql

I've managed install and run all necessary components with standard Synology packages on DS-212. 

Let me know if anyone interested. :)

Jerzy, I'm interested. Please post the steps you did to install everything.

Thanks in advance!

Yes, its all what is needed: ephem, pymysql etc. Needs few tricks to compile additional modules but its doable. 

I have created synology .spk package for weewx to make thing easer to integrate into synology native startup/monitoring/upgrade mechanism so after Synology DSM next upgrade you dont need to worry about redo all again (with your solution it will set to synology defaults).

Over the weekend I'll create some tutorial for ARM based DS but it should comply with all synology boxes.

check out: http://weewx.suzanowicz.pl. work in progress but weewx 3.0 is working :)   

[Lucas Heijst]

Hi Jerzy,

I like your web page! Good it's in English.

I noticed you have v3.0 working with meso. Did meso work right away or have you made any changes?

One minor thing. For some characters an old man like me (age 63) needs a magnifying glass (or has to set windows scaling to 175%) to read the text.

Luc

[Jerzy Suzanowicz]

scaling is temporary as I'm mainly testing this on the phone, thank you for good tip as it will be for whole family so clear reading is important.

meso works with no changes.

Forecast 3.0, mwall had put link to new custom extensions somewhere on group.

Hi Jerzy,

The new forecast is working now, but I got an error when I add (meso function) user.sync.SyncService to restful_services.

Maybe it has to do with the weewx-wd package which is not working for weewx v3.0.0a1 and commented out b me.

Looks like module user/sync.py has not been converted to work with V3.

Jerzy,

do you have a current version of the .spk file?  I am experimenting with a new Synology NAS, and am looking for the best way to get weewx running on it.  For some reason, I can't access your website at the moment (DNS not playing).

Thanks!

[Jerzy Suzanowicz]

I'm not using weewx any more. And my spk isnt updated for current weewx version

Hi, thanks a lot for the very detailed guide. I managed to get my weewx up on my ds411+ii (intel-based), though just tested the simulator station.

I already have my weewx operating on my Android-turn-to-ubuntu tv box. My questions are:

- how do I transfer all my setup, including all extensions, to the Synology. I'm not sure which folders on Synology I should copy to.

Thank you.

[ljm.h...@gmail.com]

Sorry, it is too long ago for me to remember the details. Years ago I switched for weewx to raspberry PI systems because the Synology installation had problems.

[Chotechai Piyavongsiri]

Thanks for your prompt reply. So I'd better stay on my Linux box.

Hi Jerzy, your dashboard is a personal work or some public template? can it be shared? Is awesome your weather station site.
