HS/FS Telnet Client

[marco0305]

Hi,

Since a lot of audio equipment, like Denon and Russound etc, can be controlled by telnet, the need to get a proper telnet client on the Homeserver has become a must.

Unfortunatly the Homeserver has a shortcoming that it has the 10s timeout after sending a command to close the connection. The equipment can't handle it and we loose feedback on these devices.

I know there is a workaround using a Moxa NPort or do a cyclic http request and parse but it's slow or expensive since the HS should be capable of dealing with it.

I'm not an expert but i think it can easily be implemented in a future firmware so we can control the timeout.

Maybe any of you experts can write a logic module to close the client after sending a command so the HS can receive the feedback.

Python is a complete mystery to me! I thought it was a snake

Regards

Marco

These types of python modules already exist. They do a constant TCP-connection!

Thanks Matthias,

I had a look at the python programming but it is a mystery to me.
Can Gira be asked to create a telnet client that is usable through the expert interface?
I think the average HS user is not able to program in python.
I have made logic to control the Denon and parse the feedback. To do this I use a Moxa but I rather do without it.
The html parsing for me is too slow and has to be done cyclic which is a burden.
Has technology moves quickly some of the devices are not implementing rs232 anymore. Time to move on.
So this shows the need for a telnet client.
Is there a way to create a universal logic module to do the telnet integration?

Hi Marco,

it makes no sense to ask Gira. They cannot provide a solution.

The best way would be to find a yourself Python programmer. For him it should be a very small problem to change the existing slimbox client into a telnet client. Source code is available.

Hi Matthias,

why can't we ask Gira to do it? It's in effect a computer running a linux distribution from what I understand. So to support Telnet can't be that hard or is it? I have honestly no idea.

If I look on the forum here there are quit a few people using IP controlled equipment. It seems Russound MCA-C series seams to be very popular and there are various other brands using Telnet to control.
Older equipment still has rs232 but it is slowly disappearing. And since everybody is going green why add another device (Moxa)?

I had a look at the Python coding but I need a few months at least to be able to write something myself. I compared it with the calmon written for the Fritzbox and I see a lot of similarities but they make no sense to me.
So it's going to be more of a copy/paste exercise? If I only understood what the coding does!

So maybe someone with the skills and not to forget the time feels the need to take it up? Otherwise I stay with the Moxa.
