Hi Experts,

After i have upgraded this is what i encounter:

Thanks in advance.

There is a bug in the Broadlink library we are using. I am waiting for the fix to be approved: https://github.com/mjg59/python-broadlink/pull/30

Until then you have to install crypto manually
If you use a virtual environment enable it.
Run pip install pycrypto

Wow thanks very much for swift reply. Very much appreciated, Sir!

I Just ran the pip install pycrypto and this is the error i received:

warning: GMP or MPIR library not found; Not building Crypto.PublicKey._fastmath.

Successfully installed pycrypto
Cleaning up…

Then i restarted the raspberry pi then the error from homeassistant.log:

check the indent of TV (I think should be 2 spaces not 1)
Also before the command_on and off, I did not use the -
the mac address between ’
also in friendly_name a ’ and not "

I don’t know if all above is critical or not, worth to try though

You should activate the virtual environment before you install crypto.

smart@sitha:~#source /srv/hass/bin/activate
(hass) smart@sitha:~# pip install pycrypto

I did the above, and have no error from installation. But still in error log I get this

That seems to be bug in the library we are using.
You should report to https://github.com/mjg59/python-broadlink and https://github.com/home-assistant/home-assistant

how you do that. In issues?
