ble issue

[vash3d]

Hi all,
I'm trying to setup room assistant but I've one issue.

If I set ble to true in the config file I get this error.

> room-assistant@0.4.1 start /home/room-assistant
> node index.js "index.js"

module.js:471
    throw err;
    ^

If I disable ble (set to false) room assistant starts fine but obviously it is useless

this is how I've setup the ble part in the config file:

  "ble": {
    "enabled": true,
    "channel": "room_presence",
    "max_distance": 3,
    "blacklist": [],
    "whitelist": ["6708eda4278d"],
    "use_mac": true,
    "system_noise": 0.01,
    "measurement_noise": 3,
    "update_frequency": 5000
  },

Any hint? What am I doing wrong?
Thanks.

My first guess would be that the dependency installation didn't go through correctly. Could you try removing the node_modules folder and then running npm install again?

[vash3d]

Thanks for the answer but it doesn't solve.
I forgot to say that I have to install with

sudo npm install --unsafe-perm

If I don't use the --unsafe-perm parameter I get this error during installation:

> bignum@0.11.0 install /home/room-assistant/node_modules/bignum
> node-gyp configure build

gyp WARN EACCES user "root" does not have permission to access the dev dir "/root/.node-gyp/6.11.5"
gyp WARN EACCES attempting to reinstall using temporary dev dir "/tmp/.node-gyp"

[vash3d]

I've started from scratch...
flashed an sd card with hassbian
apt-get update / apt-get upgrade
installed latests version of nodejs 9.8.0
installed dependencies:
sudo apt-get install bluetooth bluez libbluetooth-dev libudev-dev libusb-1.0-0-dev
cloned room assistant.

Then if I run: sudo npm install I get

pi@hassbian:/home/room-assistant $ sudo npm install

> bignum@0.11.0 install /home/room-assistant/node_modules/bignum
> node-gyp configure build

gyp WARN EACCES user "root" does not have permission to access the dev dir "/root/.node-gyp/9.8.0"

...endlessly

If I run: sudo npm install -g I get

And if I run: sudo npm install --unsafe-perm -g I get

Maybe the problem is is hassbian?

[mKeRix]

The only thing different from the instructions that I see here is you running npm install as sudo, which shouldn't be needed and may cause file permission issues depending on the situation. Everything else looks good to me. Possibly you should run sudo rm -R node_modules/ in the room-assistant directory to clear out the local dependency folder and then run npm install as the pi user, without sudo.

Technically Hassbian shouldn't be an issue since it is based on the normal Raspbian - which works fine for all my devices. If this doesn't work out for you I'll debug this further with an actual Hassbian instance.

(sorry for being slow with answering lately)

I had this same issue on 9.8 running on a Pi Zero W.
I ended up downgrading to 6.11.5 and had great success.

Good luck.

Im going right with readme instruction

@mredone have you tried rolling back your node version?

[mredone]

Now i roll back to 6.11.5 and everything works fine.

[voglster]

Error occurs in node 10... but working in 9.11.1
latest rasbian. Pi Zero W (arm v6)
node installed like this:
https://www.thepolyglotdeveloper.com/2018/03/install-nodejs-raspberry-pi-zero-w-nodesource/
worked out of the box

[madrose]

I had exactly the same issue on a raspberry Pi, and I noticed that the room-assistant folder is owned by root after I did git clone. I did sudo chown -R pi:pi ~/room-assistant and run the commands again.
All worked after that
