2 years ago Hi there, nice present👍
This isn’t a pure nodejs project - it relies on a python module for the heavy lifting.
Did you follow these installation steps from the readme?
Ensure python is installed and on the path
Install the python project: pip install jvc_projector_remote

2 years ago The N5 is a beast and big fun indeed!
Yes, python is installed, and apparently invoked with the script. And yes I installed the package too, but can't verify that location and owner are correct. What's the requirement there?

2 years ago Maybe the version of python in use e.g. via the config for this plugin (python_path) is not the same python in use when you did pip install jvc_projector_remote. This would explain why the pip install completed, but when python is invoked from this plugin, it can't find the installed module.
You will need to check the python location used and the path it installs the jvc_projector_remote when you run pip install jvc_projector_remote and ensure the same python location is configured as python_path.
Maybe use a combination of pip show: https://pip.pypa.io/en/stable/cli/pip_show/ and which python (assuming you are on a unix environment).
If this doesn't work you will need to delve deeper following something like this: https://www.devdungeon.com/content/python-import-syspath-and-pythonpath-tutorial#toc-5
Maybe try something like:
pip install jvc_projector_remotethen:
python
>>> from jvc_projector import JVCProjectoras per the article you can also check:
>>> import sys
>>> sys.pathand you might need to set PYTHONPATH

furthermore I got this:

ConnectionRefusedError: [Errno 111] Connection refusedOK so it looks like a network connection issue between homebridge (python module) and the projector:
ConnectionRefusedError: [Errno 111] Connection refused
It could be A. a setup issue or B. this bug noted here:
https://github.com/bezmi/jvc_projector#bugs
For A, can you confirm the IP of the projector is 192.168.0.16 and that from home bridge you can connect to the projector manually (JVC control protocol seems to be port 20554). Use something like http://nmap.org from the synology container:
nmap -A 192.168.0.16/32 -p 20554
You should at least see it is open if you get different behaviour than when trying to connect to another random port e.g. 20555
Maybe also check if you need to enable network control in the projector settings?
For B, it could be that the plugin configured delay for connection_delay_interval is not a long enough delay between commands and hence you see the mentioned bug. I am using a JVC NX7 so maybe it is ok for me, but not for the NX5. If you can confirm point A seems OK, try also increasing connection_delay_interval.
If you still have an issue, send me the full clean logs from home bridge startup and maybe I can see what is happening further. e.g. maybe the delay I have implemented isn't working correctly.

on and off!Yet the plebs was dissatisfied and asked for more :-> For sure you've already thought of expressing various other commands in addition to power-on/off :->
just curious II; Do you see a powerstate=ON reflected in the homebridge/homekit button?
Mine remains gray, and [Beamer] Returning projector power: OFF is logged even when device is ON.

2 years ago While the projector is turning on or off it reports the previous state for a while. Is that what you are seeing?
My projector looks like the following in the home app and it will reflect the state as on when it is turns on from here.

Hello! I'm having the same issue trying to get this plugin to connect. I also have Homebridge running on a Docker container within my Synology server.
This is where I am stuck:
/usr/bin # which python
/usr/bin/python
/usr/bin # ls -al pyt*
lrwxrwxrwx 1 root root 7 Dec 25 19:46 python -> python3
lrwxrwxrwx 1 root root 9 Dec 2 00:44 python2 -> python2.7
-rwxr-xr-x 1 root root 13992 Apr 21 2020 python2.7
lrwxrwxrwx 1 root root 9 Dec 1 23:12 python3 -> python3.8
-rwxr-xr-x 1 root root 13992 May 6 2021 python3.8
How can I get to switch to /usr/bin # ? So I can run that ls -al pyt* command and link it to the correct path?
Thanks for any help!

2 years ago problem is, the python module jvc_projector never, even after along while, reports the projector as ON.
though blind switching it ON/OFF works.
How can I get to switch to
/usr/bin? So I can run thatls -al pyt*command and link it to the correct path?
so in your browser:
DSM andhomebridge container, Terminal Tabcreate / Launch with command a new sh shell and find yourself in /homebridgecd /usr/bin and set the python symlink(s) straight...this indeed is the most challenging issue, that the python version used and installedto in the shell matches the version invoked in homebridge.

Please excuse my ignorance, but once I type cd /usr/bin, how do I set the python symlinks straight?

better copy&post the output of ls -al pyt* before you set anything!

Ok, I got it working and I was able to turn on the NX7 using the switch but the switch will go back to OFF seconds after I click on it. It will go back to OFF but the NX7 will still be ON.
I guess I just need to have the switch show the current projector state.

2 years ago @aschmidt74 i wonder if this PR would fix the issue with the state check in the python module? https://github.com/bezmi/jvc_projector/pull/10
I can’t work out why I am not seeing this. I will check again when I get a chance.

Ok, I opened up a SU terminal window as shown above in this thread. Now, how do I edit the init.py file's line 181 to read on = [PowerStates.lamp_on.name, PowerStates.reserved.name] ?
I would greatly appreciate it!

line 3 from:

I seem to miss something basic here:
wherefrom should
