Thanks for looking into it - I should have thought to manually update when troubleshooting anyway but forgot at the time.

Thanks Erik!
I will look into this asap and possibly update the project to use Motion 4. There are a lot of improvements I would like to make.

Oh, wait a second, I've changed this recently, it was installing the version 3 straight from the repository but now the install script is using apt-get. The apt-get command is probably not installing the last version. Anyway, I will look into this and make sure I'm doing the best approach to install motion in the system.

Hey Geraldo-
I received a new Pi Zero W today, This Pi Zero I bought for the express purpose of building a security camera to cover my front door...As it's a new Pi I started with the latest version of Raspbian (Stretch) which comes with Motion 4.0-1. To my surprise I was also getting the same "Unable to open video device" screen as I had with the other Pi running Jessie.
At first I tried an apt-get update/upgrade however this did not upgrade Motion and left it on 4.0-1. Again I had to manually update from the Motion repository:
wget https://github.com/Motion-Project/motion/releases/download/release-4.0.1/pi_stretch_motion_4.0.1-1_armhf.deb
sudo dpkg -i pi_stretch_motion_4.0.1-1_armhf.deb
Once it was updated to Motion 4.0.1-1 from 4.0-1 everything started working.
HTH,
Erik

Thanks Erik.
I think the issue is not related to the version itself, check this out:
https://raspberrypi.stackexchange.com/questions/27737/unable-to-open-video-device-and-grey-screen
Looks like running sudo modprobe bcm2835-v4l2
should fix the grey screen issue.
I will see if it makes sense to add this as part of the installation script. For now, I will include this tip in the readme file so people who are having this issue can try sudo modprobe bcm2835-v4l2
. I will also mention installing from the repo as a second option.
Thanks for helping to troubleshoot this.

Thanks Geraldo,
I built another one today, same problem initially but then sudo modprobe bcm2835-v4l2 fixed it.
Thanks,

Thanks, I will add this to the install script. Looks like for some reason it's not doing it out of the box as it used to do before.
