Pjlink temperature readings

Hi There,
I am fairly new to Node-Red. I have found my way around.
I use node-red for my video installations.
The pj link ( node-red-contrib-pjlink) is very handy to work with, to turn on and off projectors.
I would additional like, to read the temperature of the projector...
Has anyone experience or accomplished this so far?

Thanks!
Vincent

Hi Vincent
Are you using PJlink over Lan or over RS232?
i am trying to use natcl's Node Red commands but it is unclear in his documentation whether he is using RS232 or Lan to connect

Hi,

I use PJlink over LAN.
It is not that complicated.

  • connect projector lan to the same network as the node red server.
  • assign a ip to both. note down the IP adres of the projector. Also, and it is best to refer to the user manual, find projector's default login or set it in the projection menu.
    I use panasonis, most times the default is user1 login and panasonic as password
  • in node-red create a pjlink node
  • in the node settings fill in the ip adress, default port is ok, fil it in! it is sort of greyed out.
  • name is the loginname, that is a bit confusing, since loginnames of multiple porjectors are all the same!
  • password is password.

If you send a message topic ON or on to the projector, it will turn on.
If you send OFF or off the projector will turn off.

notes:
some projectors do need to set an password since blank does not work. especially more older projectors (PJ link rev 1.0)

it is also possible to torn on or off projectors through rs232. but this does not work with the node red contrib.

My guess for that is to start here:

Good luck!
