Controlling JVC projector through TCP/IP using hex commands

[andydmack]

I’m in the exact same boat. Did you ever get this solved? I’d add $20 to the pot…

[123 (Taras)]

To my knowledge, there’s no TCP/IP component available. However, someone else had a similar need (control relays via TCP/IP) and the solution was to use linux’s nc command (netcat) via Home Assistant command_line switch component.

TCP commands for Ethernet relay

I’m not sure what is the best component to use to control an Ethernet relay board. Despite what the vendor says, there is not rest API, just a plain TCP socket communication. Here what I’m trying to do: eight lines, let’s call them CH1…CH8 I have ip address and port to switch on a line I have to send over a TCP socket 1n where n is the number 1…8 (i.e. 11 turns on the first line) to switch off send 2n (i.e. 21 turns off the first line) adding :x will add a delay in seconds (i.e. 11:10 will tur…

I’m still trying to get this figured out. Currently I’m using the Web 2-way plug in for control4 to send an http command to have Control4 turn on and off the projector. If I figure out how to cut the Control4 part out of it, I will post on here. I can do it using the Hercules app (not on HA), so I feel confident that it can be done, I’m just not knowledgeable enough in this area. Hopefully, you can beat me to it though

If you have control4, let me know and I can show you what I did.

Hey mate, I’ve got a DLA-X5900 and I’ve got a working module with on/off and lens memory commands. I believe your projector should use the same commands for on/off. I didn’t see the need for the other commands, so I left them out, but should be able to add them, it’s relatively straightforward.

I have tested on hassbian, not sure what you are running, but I will get the module added to PyPi and upload the custom component to github in the next couple of days. If I forget, just reply and I’ll get on to it.

Hey guys I am trying to achieve the same thing with a TCP based thermostat. Any ideas how HASS can emulate the three way handshake?

[bezmi]

You can write a python or bash script that communicates with the device using the socket module (python) or netcat (bash).

[mitchmario]

Great, do you know of any examples of this in HASS or elsewhere?

[bezmi]

I don’t know of any specific examples that do the three way handshake. For a thermostat you’d probably want to write a custom component, so you’d have a python file with a class that communicates with that component and another file with the homeassistant component code. When I upload the code for the JVC projector, you’ll be able to see how to write the code that communicates with the device, as well as how to interface that code with a remote component, however if you need a different component you’ll have to go through the ones in the homeassistant source to get an idea of how to do it.

Perhaps if you make your own post, others might be able to weigh in with alternative solutions.

[mitchmario]

Thank you, I don’t have any coding knowledge so I look forward to your JVC projector component (any comments in the code would be great ) I have made my own post so we’ll see if there’s any other options.

[abalakov]

Why don’t you use a RM Mini 3 to emulate your remote control?

It is $20,- (the amount you would spend to charity)

It is quick, easy and cheap.

[bezmi]

Whilst it is definitely an option, I am not a big fan of IR control for automation. With serial/IP control, the projector is able to report its state to the controller.

Since the IP control is available and works quite well, I see no reason to default to IR.

@johnnypink1, @andydmack , I’ve made a post for my remote.jvcprojector component here.

[andydmack]

Looks great - but unfortunately I’m using Hassio and can’t install your module using PIP. Is there a way to install on Hassio?

[bezmi]

I will look into deploying it as an add on.

[johnnypink1 (John Pinkstaff)]

Thanks for the reply. My retina detached so I’m laid up for a week after surgery. I’ll give it a try when I’m back on my feet. Didn’t want you to think I was ignoring your efforts

[bezmi]

I have added a Dockerfile based on examples, so it might work as a hass.io addon. I don’t have hass.io to test, so if you get the time, please try to install it and let me know if the logs throw up any errors.

[johnnypink1 (John Pinkstaff)]

I tried to install it as an add-on in hassio and I got this:

“Integration jvcprojector not found when trying to verify its remote platform.”

Any ideas on anything I should try? Thanks

[bezmi]

It is most likely an error with my configuration of the add-on. I will get Hass.io running on a spare sd card in the next couple of days so I can do some testing.

[bezmi]

I decided against trying this as a Hass.io add-on, because it isn’t really a server based thing like the other add-ons. Instead, you can install this as a custom component with the SSH add-on. I have updated the install instructions in the repo.

On my Hass.io install, it pulled the required python module automatically, so you should just be able to copy the jvcprojector directory into the custom_components directory, update your config and restart Hass.io.

I was playing with my JVC projector as well and used first bezmi’s pyhton code. As I wanted a smartphone app, I wrote my own. Maybe this is an option for you as well.
The android project can be found on github: GitHub - LaUs3r/JVCProjectorRemoteControl: Android app to control JVC projectors using the LAN interface
