Implementation of lens control command

[josh-79]

Hello,

I use a JVC N5 projector in my home theater. Currently I have connected the projector via the FHEM Smart Home software. I would now like to switch to the Home Assistant component. Unfortunately, I am currently missing the following command in the Home Assistant component:

"Lens Control“

This command opens directly the focus menu without the need to enter it via the setup menu. According to JVC documentation, the command can be called via the following remote code:

Hex Code: 21 89 01 52 43 37 33 33 30 0A ASCII: 30 Source (Page 10)

In FHEM it is possible to send a specific remote code. I use the remote code 30 to execute the command.

Could this command also be implemented in the Home Assistant component? Maybe you could integrate a command to send any ASCII remote code?

sure let me see what I can do

in HACS please update to the latest beta release. You will need to allow beta releases should be v3.6.99

You can use send_command service to send something like remote,30 as a value which will execute ascii code 30 using Code A (73)

Make sure to restart and stuff. If you have issues, turn on debug logging for the jvc component only and try again, then post logs

logger:
  default: warning
  logs:
    custom_components.jvc_projectors: debug

Wow, thank you for the very fast implementation. I will test the beta version tonight and then give feedback.

Hello,

sorry for the late feedback. I have been trying to get the new beta version to work for the last few days.

The old commands work perfectly (e.g. "lamp_power,normal").

However, I have not been able to get the new "remote" commands to work. I have tested "remote,30", "remote,2e" and "remote,03".

I get the following error message in the log:

Am I doing something wrong or is the error in the plugin?

please try 3.6.6. I just tested on mine and was able to send remote commands

[iloveicedgreentea]

I also added menu,lens_control which opens to that menu but its not in this release will be in the final one

[iloveicedgreentea]

I released 3.7.0 which adds all of these actually

[josh-79]

I have tested version 3.7.0. It works perfectly (both: "menu,lens_control" and "remote,30"). Thanks for the implementation.

I have also tested version 3.7.1. Here I get the following error message before restarting HA:

Platform error remote.jvc_projectors - Requirements for jvc_projectors not found: ['jvc-projector-remote-improved2==3.7.1'].

thanks I put the wrong library version its fixed now
