Script reboot failing
#1
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.

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

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

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!!

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.
