@aequitas, thanks for your PR! By analyzing the history of the files in this pull request, we identified @fabaff, @martinfrancois and @pvizeli to be potential reviewers.

Looks good to me, although I couldn't really test it myself, since I don't own any devices like that. Would be interesting to hear from @bobmccall since he/she opened the issue up if it was fixed.

Happy to give it a go, but not being a developer you'll need to tell me exactly which files to put where.

I've tried copying the new rflink.py into
/usr/local/lib/python3.4/dist-packages/homeassistant/components/switch & restarting, but still I saw the same problem with alloff. I have no idea if this is the right thing to do?

Not sure what to do with the other two files tests/components/light/test_rflink.py and tests/components/switch/test_rflink.py?
Thanks

If you place just the rflink.py in <configuration>/custom_components/switch/rflink.py it should be good.

OK, given it a go...
I have 3 newkaku switches as configured here https://github.com/home-assistant/home-assistant/issues/7522.
Restart HA with new rflink.py in /home/homeassistant/.homeassistant/custom_components/switch

Turn on switch 3 with remote - switch turns on
Turn off with alloff - switch 1 turns off, switch 2 no action, switch 3 remains on

Here is what we have in the log...

Can you try adding the group aliases in the configuration: #5969 (comment)

This is currently not documented.

[kitkat270]

Yes! That works great.
