pyCEC install on Raspberry Pi

Third party integrations
1

Hi HA guys

I need some assistance (probably quite basic for most here. :slight_smile:) .

I have my main Homeassistant install on an HP microserver running Ubuntu server 17.10

I also have a Raspberry pi (Model B, 512MB) in my lounge, connected to a Samsung TV via HDMI. cec-client is installed and I have a positive good response with this command:

echo scan | cec-client -s -d 1

pi@raspberrypi:~ $ echo scan | cec-client -s -d 1
opening a connection to the CEC adapter…
requesting CEC bus information …

BUT…

I just cant get pyCEC installed / running…and actually have no real idea of how to get it from github correctly.

Anyone that can advise me on the commands to install it, or guide me to a good, simple link explaining how to, I havent found anything yet.

I hope someone can assist me…I keen to get my system running, but this is all a steep learning curve for me.

Thanks in advance.

I’m in the same position.

I have compiled libcec via these instructions and all seemed fine. https://github.com/Pulse-Eight/libcec/blob/master/docs/README.raspberrypi.md

running python3 -m pycec as per pyCEC does not work.

Error for info:

pi@raspberrypi:~/libcec/build $ python3 -m pycec

Thats exactly the same error I received. I cannot find a solution yet with tons of googling…
:frowning:

I think it’s something to do with pointing to the compiled version of libcec, but I can’t figure out what.
