Switch off all devices beginning with text - if switched on

I want to switch off all devices starting with text light, only if they are on.

What would be the easiest way to do this?

What do you mean "starting with text light"?

The device is called like this:

Light kitchen
or
Light bedroom
...

Something like this:

Code: Select all

for dev in indigo.devices.iter():
    if dev.name.startswith("Light"):
        indigo.device.turnOff(dev)


Thanks a lot for the quick reply. It helps a lot.

Here is my full script in case someone wants to use this as well.

The goal was to switch off all lights in an efficient way.
- only switch off if really on
- turn off all lights except one (Light Exception)
- wait 1 second between every light to avoid network overload - but only wait if one light has been switched off

Code: Select all

import time

for dev in indigo.devices.iter():
    if dev.name.startswith("Light") and indigo.devices[dev].onState and dev.name != "Light Exception":
        indigo.device.turnOff(dev)
        time.sleep(1)

This version is more efficient since it doesn't get the device from the server twice:

Code: Select all

import time

for dev in indigo.devices.iter():
    if dev.name.startswith("Light") and dev.onState and dev.name != "Light Exception":
        indigo.device.turnOff(dev)
        time.sleep(1)

Thanks jay, for pointing that out.
