Device Sharing

[duodiscu92]

Hello
sorry to raise a topic that has probably already been discussed but I can't find an answer in the forum (maybe I'm not looking well for it)
I am trying to establish a master-slave relationship between two Domoticz servers and strictly following the indications of the Wiki (Device Sharing)
and in the log I have the following messages:
2019-12-02 18:40:55.122 Status: Domoticz Remote: connected to: 192.168.1.66:6144
2019-12-02 18:40:55.127 Error: UNHANDLED PACKET TYPE: FS20 68
2019-12-02 18:41:25.132 Status: Domoticz Remote: connected to: 192.168.1.66:6144
2019-12-02 18:41:25.137 Error: Domoticz Remote: input buffer out of sync, going to restart!....

Master and slave are on two Rapsberry Pi on the same local network.

Thank for your help

Hi,

Could you provide a little bit more information?

Regarding the posted log file:

2019-12-02 18:40:55.122 Status: Domoticz Remote: connected to: 192.168.1.66:6144
2019-12-02 18:40:55.127 Error: UNHANDLED PACKET TYPE: FS20 68
2019-12-02 18:41:25.132 Status: Domoticz Remote: connected to: 192.168.1.66:6144
2019-12-02 18:41:25.137 Error: Domoticz Remote: input buffer out of sync, going to restart!....

Is this logfile your master logfile or your slave logfile?
Which "hardware" devices has been connected to your slave?

Perhaps some screenshots of both master and slave configuration might be helpfull.

Regards

[duodiscu92]

This is the log on master side.

I have tested two configuration on slave side :

1) with a real sensor (a Xiaomi Temperature+Humidity Bluetooth sensor) installed as described on
https://franken3d.blog4ever.com/integre ... r-domoticz
which is the French translation of
https://github.com/pFenners/mijia-sensor-domoticz
2) with no hardware (to be sure that the bug doesn't come from python code), the sensor is purely virtual.

In both two configuration the messages in the log are the same.

Attached are some screen shots:

Additional information

Both two Raspberry Pi have the same version of Domoticz installed (the most recent)
I have read on an old post that it could be an issue of size of a buffer. But which buffer? How to resize it ?

[FireWizard]

Hi.

Both two Raspberry Pi have the same version of Domoticz installed (the most recent)

In your profile, you indicate that you are running the latest version. I assume the latest stable version 4.10717.

As you said earlier, you followed the wiki
Let's do some checks:

1. In the slave you have set a password for the website protection.
2. Remote shared port 6144
3. In "Setup" => "More options" => "Edit Users" you have set a user with the password and gave him admin rights and setup the "Active Menus"
4. In the Master you have specified in "Settings" => "Hardware" the correct values for IP Address, Port (6144) and the previous Username and Password, as configured in the slave.

I suggest that you remove all hardware from your slave and install only "Motherboard Sensors" in your slave.
Do not forget the enable "New Hardware" in your Master.

This should function and you should see new sensors in your Master, representing the Motherboard Sensors of your slave.

Regards

[duodiscu92]

As shown below I have done the check you suggest and removed-replaced the hardware on slave side as suggested.
But I have the same error messages in the log of the master

2019-12-04 04:15:20.870 Status: Domoticz Remote: connected to: 192.168.1.66:6144

See details below

In your profile, you indicate that you are running the latest version. I assume the latest stable version 4.10717

I confirm

1. In the slave you have set a password for the website protection.

YES

2. Remote shared port 6144

YES

In "Setup" => "More options" => "Edit Users" you have set a user etc ...

YES

4. In the Master you have specified in "Settings" => "Hardware" the correct etc ...

YES

I suggest that you remove all hardware from your slave and install only "Motherboard Sensors" in your slave.

DONE, see screen copy

What do you mean ? as on this screen copy ?

Something strange ...

Looking the log on master side this message is supposed to mean that the master is connected to slave

2019-12-04 08:03:44.695 Status: Domoticz Remote: connected to: 192.168.1.66:6144

But looking the log on salve side I can see only one incoming connection : this is the connection of my laptop.

2019-12-04 08:07:06.763 Status: Incoming connection from: 192.168.1.47

Should I see the master's connection (192.168.1.39) or is it treated separately?

[FireWizard]

Hi

1. What I mean with:

Do not forget to enable "New Hardware" in your Master.

is the following:

In "Setup" => "Settings", you have the following option:

Checkbox_Enable_hardware.png (69.95 KiB) Viewed 4599 times

Click the checkbox, marked "Accept new Hardware Devices" or click "Allow for 5 Minutes".

And don't forget in "Setup" => "Devices" to click the green arrow for your devices, so that it turns to blue
Otherwise you will not see the devices under the "Temperature" and "Utility" tab.

Yes, if you startup the Domoticz process in your slave you should see in "All" the following:

In my case the "Master" has IP address: 192.168.10.50.

On the "Master", you see a line in the log, like:

2019-12-04 13:43:55.057 Status: Domoticz Remote: connected to: 192.168.10.51:6144

In my case the "Slave" has IP address: 192.168.10.51.

So in both machines you should see, that the "Master" is connected to the "Slave".

If the "Master" is updated, you should see in the "Master" log, lines, like:

2019-12-04 13:46:36.203 (Raspberry Pi 1) General/Percentage (Raspberry Pi 1 CPU_Usage)
2019-12-04 13:48:06.399 (Raspberry Pi 1) Temp (Raspberry Pi 1 Int. Temperature)

2019-12-04 13:49:36.581 (Raspberry Pi 1) General/Percentage (Raspberry Pi 1 HDD /)

(Raspberry Pi 1 is the name of my "Slave")
You don't see anything on your "Slave".

So obviously, as you see only the connection of your laptop and not the Incoming Domoticz connection from your Domoticz "Master", I think that the connection not has been made. Strange.

Is there anything in your "Slave" that may prevent, that a connection is made?

Regards

[duodiscu92]

Thank you so much for your help.
I followed all your recommendations but the problem is persistent.

I suspect that this comes from my slave who also performs data transfers to the master using the MQTT (Mosquitto) protocol which can generate a conflict with device sharing.

Or maybe a problem on the master side running on a Raspberry type B which is a little obsolete. I will try an experiment with two other Rapsberry Pi dedicated exclusively to device sharing...

[FireWizard]

No, that cannot be the reason.

My Domoticz "Slave" is a Raspberry Pi 1B, the first generation.
On that Pi, I have installed Mosquitto, Node-Red and Domoticz (latest beta)
I have multiple flows in Node Red communicating with my Domoticz "Master", using MQTT.
On Domoticz "Slave" I have only the Motherboard Sensors installed, and thats why I asked you to do the same. I have also MQTT communication with a Raspberry Pi 3+.

My Domoticz "Master" is a Raspberry Pi 2B.

So, I'm communicating between a RPi 1B and a RPi 2B with MQTT and Domoticz Remote server in parallel as well.

You can try a clean installation on new SD cards.
[Edit] I studied your error message once again.
It could be a buffer issue in your "Slave" RPi.
I suggest that you test with the same hardware, but with the latest beta release.
Buffers has been increased since 4.11079

Regards

[duodiscu92]

Right : moving on new Rpi's doesn't change anything.

I have updated both master and slave with the last beta version

Now the log on master (a Rpi Zero W) is

I am really lucky ...

[duodiscu92]

Seems now that the master connects and immediately disconnects

[duodiscu92]

For an unknown reason it seems that the connection between master and slave tween cannot complete.
Maybe an issue with the router configuration ...

I will try to build a second independent LAN (using another router I have) and to connect the master and the slave on it.

[FireWizard]

HI,

I have seen that you use as "Master" a Raspberry PI Zero W.
Have you seen this topic: https://www.domoticz.com/forum/viewtopi ... =6&t=30414

I suggest, that you build a small network, consisting of 2 PI's, directly wired (not wireless) together.
And use the latest beta.

Regards

[duodiscu92]

Hi

I have done many test in various configuration.
I replaced the Rpi Zero by a Rpi model 3 with ethernet socket.

Both two Rpi run the last Beta version of Domoticz
I tested Wifi and Ethernet connection with my box as router or with another router independent of the box

But it don't work anyway.

So i think I am going to give up ...

Thanks again for your for your help.

Hi,

That's not in my vocabulary, however I cannot force you to go on.

Let us look to the slave first.

In the log of the slave I see:

2019-12-10 10:31:04.900 Status: WebServer(HTTP) started on address: :: with port 6144

Why did you change the web server's http to another value than 8080?
If there is any valid reason to do so, because you have planned to use this port for something else, you can change it. However do never change it to 6144, because this is the port that is used by Domoticz Remote server.
This will definitively cause a conflict and you will see that 3 lines later:

2019-12-10 10:31:04.916 Error: Exception starting shared server: bind: Address already in use

And this explains also:

2019-12-10 10:31:34.711 Error: Error parsing http request.
2019-12-10 10:32:04.735 Error: Error parsing http request.

2019-12-10 10:35:16.578 Error: Error parsing http request.

So lets change this first and I suggest to use port 8080.

nano /etc/init.d/domoticz.sh
Edit this line, so that it looks like: DAEMON_ARGS="$DAEMON_ARGS -www 8080"
If you open your editor, you will see 6144 as port. Change it to 8080
Leave the editor and give the following commands:
systemctl daemon-reload
service domoticz stop
service domoticz start.

If everything is alright, you will see:

Hi,

That's not in my vocabulary, however I cannot force you to go on.

Ok let's continue ...

I will apply your recommendations and let you know ...

Write you later.

Best regards

[duodiscu92]

Done as you recommended.

Note the message

Seems to be an old bug discussed on the forum

[FireWizard]

Hi,

For the moment I suggest that you disconnect your master from your network. I wonder who is making a http request. It is exactly 30 seconds.
Is there anything else that tries to connect with the slave? Another Pi? Wireless?
