Dobrý den, prosím o radu.
Potřebuji "něco" hardwarového na čem poběží Linux na kterém poběží script Solaxmax Watcher.
http://sourceforge.net/projects/solarmaxwatcher/
Bude to mít jen za úkol po LAN siti pristupovat do měniče pro fotovoltaiku a číst z toho data a zapisovat je do MySQL.
Samotné MySQL na krabičce nepoběží.
- důraz na nízkou spotřebu a pořizovací náklady
Máte někdo tip na vhodnou "linux krabičku" a "jakou distribuci Linuxu" použít. Nejsem Linuxář a nerozumím tomu.
Díky
Zde jsou požadavky na instalaci scriptu (viz odkaz výše)
-----------------
1. The smw-logger
=============
Requirements
------------
mysql client library (libmysqlclient)
a running mysql-server
Compiling Instructions
----------------------
- change into the logger-folder of this archiv
- compile with:
gcc -W -Wall -Wextra -Wshadow -Wlong-long -Wformat -Wpointer-arith -rdynamic -pedantic-errors -std=c99 -o smw-logger smw-logger.c -lmysqlclient
Running
-------
- run install.sh script to install and configure the complete software by typing
./install.sh
or install manually ...
- edit and execute the 'bin/create_db.sh'-script of this archive to create the mysql-db and the
required tables. If more than one inverter should be logged, you have to repead executing the
script with diffrent table-names (log1, log2 etc.)
- copy the logger to the prefered path, e. g. /usr/local/bin/
- edit the config-file and copy it to the prefered path, e. g. /usr/local/etc/
- edit init.d-script, copy it into the /etc/init.d/ - folder and make it startable.
- Run with: /etc/init.d/solarmax-logger start
It is recommended to schedule the logger to be started between 5:00 - 6:00 in the morning and
stopped between 22:00 and 23:00 in the evening (compare with sunshine duration). The logger
has no built-in facility for logging, so use CRON or similar. I use the following CRON entries:
00 05 * * * /etc/init.d/solarmax-logger start
00 23 * * * /etc/init.d/solarmax-logger stop
If more than one inverter is installed, connect the 1st one with your LAN and set it to ID 001.
The others have to be connected via RS485 in ROW, with ascending ID's (002, 003 ...) and disabled
LAN interface.
If you want to unistall the software either in parts or complete you can run the uninstall script by typing
./Solarmax_uninstaller.sh
with root rights. It guides you through the options of uninstalling.
