[Nut-upsdev] nut driver for SMS (brazil) UPS

[Thiago Tiedtke dos Reis]

Hi,

Recently I got three units of this nobreak [0]:

The intention is connect it with some file server and/or web server.

I found the NUT via FreeNAS [1] , and the contribuition [2] of Ulisses and
Rodrigo about this vendor SMS, in Brazil.

But, initially, i'm trying to apply the Ulisses patch (for smsbrasil
driver) in a Debian Server, with no success.

Can anyone help me about the patch in these two link [3] or [4]?

I'm using Debian GNU/Linux 7.4 (wheezy), in a 64bit machine.

If you want, I can do some testing with my nobreaks for improve the driver.
I have some knowledge about C programming, eletronic devices, linux
(debian), but no much about debian packages lol ..ok

Thanks on advance!

Best Regards,

According to the HCL, for the Manager III, you might want to try the blazer_ser (or in 2.7.1, nutdrv_qx):

For reference, can you post the output of 'lsusb -vvv' for this UPS?

[Thiago Tiedtke dos Reis]

Hi Charles,

I'll try the blazer_ser and the nutdrv_qx with version 2.7.1 later.

Below, the result of 'lsusb -vvv' requested:

When I try to use blazer_ser, the command: sudo upsdrvctl start

Result the below message:

Network UPS Tools - UPS driver controller 2.6.4
Network UPS Tools - Megatec/Q1 protocol serial driver 1.55 (2.6.4)

Unable to open /dev/ttyUSB0: Input/output error

Current user id: nut (116)
Serial port owner: root (0)
Serial port group: nut (122)
Mode of port: 1660

Things to try:

- Use another port (with the right permissions)

- Fix the port owner/group or permissions on this port

- Run this driver as another user (upsdrvctl -u or 'user=...' in ups.conf).
See upsdrvctl(8) and ups.conf(5).

Fatal error: unusable configuration
Driver failed to start (exit status=1)


If I try to access the port /dev/ttyUSB0 using minicon (minicom -D
/dev/ttyUSB0) or cat ( cat /dev/ttyUSB0 ), the access to device is denied.

Then, I try these instructions [0], but nothing changes when I try to open
the serial port:


# /etc/udev/rules.d/99_nut-serialups.rules
KERNEL=="ttyUSB0", GROUP="nut"

My /etc/ups/ups.conf has the following configuration:

[ups]
driver = blazer_ser
port = /dev/ttyUSB0


Any tips about that?

Thanks!!

For sms ups with USB connection you should use smsbrasil from Ulisses.

The driver should be considered alpha, due to some unexpected behavior. It
works, somehow. I can't recall which version was the best one, but it
wasn't the last ones (some of them didn't properly report online->battery
changes and etc)
