Script reboot failing

[fbrun@domizy]

Hi,

I'm trying to reboot a wiser for KNX with a script.
Using this "os.execute('reboot')", the server doesn't reboot.

I also tested this "os.execute(reboot)" but i have the same result.


Respectfully,
BRUN Félix.

In General configuration there is Block unsafe functions in scripts:
Make sure to disable it.

Hi,
I have the same problem as fbrun@domizy to reboot LM5, I don't understand Daniel's answer

Thanks Daniel, it's OK

Is it also possible to reset the USB port by script, I have a Uart rs232 which from time to time blocks and I am obliged to unplug and replug

[Daniel]

What is the device you have problem with?

[JMM]

It's : FTDI - FT232R USB UART

[Daniel]

Did you check if just reboot helps? I think it will need power down anyway.

[JMM]

Yes reboot helps, I read the frame of a Linky electric meter every minute, some day at 8:00 a.m. the meter sends the tariff change and the ft232 blocks so either reboot or disconnect reconnect

It's not from the script!!

It's OK With the help of Claude.ai

You can power cycle USB port like this:

Code:

1234

io.writefile('/dev/usbctrl', 'low') os.sleep(1) io.writefile('/dev/usbctrl', 'high') os.sleep(1)

Make sure that serial port is not open in a script when doing the power cycle. Otherwise the port name might change and script won't work.
