It works !

Indeed it was a port issue.

The good configuration is : port 8080 for both Master and Slave as you recommended, but 6144 in the Remote Server Config (see screenshot below)

The next step will be to test a similar configuration on my normal installation (a Rpi Zero and a Rpi B+) with my Xiaomi sensor and non-beta domoticz version.

Thank again "FireWizard" for all.

Best regards

Ok, that is nice to hear.

And you know: Never give up :D

Right ... never give up

So it works well in my standard configuration Rpi Zero and Rpi B+, Wifi network, last non-beta Domotics version.

All "Motherboards Sensors" are well shared. But the Virtual Sensor I use for my Xiaomi sensor is not shared properly, I mean visible on slave side but not visible on master side.

I think it is an issue already discussed on the forum : Vitual Sensors seems difficult to share.

Trying now to solve this new issue ... :D

Hi,

Indeed, I have the same with virtual sensors. Mostly Python scripts.

See: https://github.com/domoticz/domoticz/issues/2642

But you said that you are running MQTT in parallel. Maybe you can try that.

Yes this is what I have done and it works

But after all these efforts to make working device sharing it's a real pity not to be able to use it for virtual sensors.

I fully agree. I also find it strange that there is no warning against this in the Wiki. There is an excellent step-by-step description of the Device sharing setup. But nothing about omission of virtual devices...

I understand that, but it feels a bit wrong. I think the author of this particular piece of code is the ideal person to maintain the page.
Having said this, if that person won't/can't do it, I guess I'll voluteer... I will add some text.

A while ago, I had the need to send any kind of device (dummy or not) to a remote domoticz, so I wrote this little LUA function to do it easily via json

Code: Select all

function UpdateRmt(credentials,ipp,local_dev,remote_idx)
    --[[Update a sensor on a remote domoticz
    credentials : string "login:pw" of remote domoticz
    ipp : string "ip:port" of remote domoticz
    local_dev : name of local device to transmit
    remote_idx : index of device on the remote domoticz
    ]]--
    
    cmd = "http://"..credentials.."@"..ipp.."/json.htm?type=command&param=udevice&idx="..tostring(remote_idx).."&nvalue=0&svalue="..otherdevices_svalues[local_dev]
    --print(cmd)
    os.execute('curl "'..cmd..'" &') -- Or we could do it with a 'OpenURL' in a CommandArray...
end
You can call the function at your choice on a devicechanged or regularily...

This could be helpful, but it would mean opening the Domoticz port through my router. Is that safe? I assumed that the "device sharing" port is OK, but the regular IP port?

OK. Nice solution. I first tested this while port 8080 was routed through my router to the R-Pi on which Domoticz runs.
I was able to send values into my Domoticz devices, so the mechanism works.
Obviously, I did not want to keep 8080 open for a second longer than really needed to test, so I removed that NAT line, and instead entered 443.
Changed "http" into "https"in your code, and 8080 into 443.
Unfortunately this does not work. Also tried removing the port alltogether, but no.

I then tried using a browser from outside my network, using the https connection works OK (although I do get a warning from the browser). This proves that my NAT settings are good.
Any suggestions?

I did not test this, as my remote domoticz was accessible from inside a VPN. I'll make some tests with https to understand what's going on

I am looking at a new approach to get virtual device values across to the master domoticz.
Perhaps I could somehow create a device, copy the value into that, and catch it at the master side?
I have three virtual devices, with values from the speedtest: upload Mbit, download Mbit, and ping msec.
Any recommendations as for the type of transport device I should be using?

Hi manjh,

Did you see my last post at: https://www.domoticz.com/forum/viewtopi ... 60#p234060

I believe probably the simplest way to go is to use MQTT.

Ah, thanks. I had not seen that yet.
I do need Domoticz on the remote location, and I also want to be able to see the speedtest results in Domoticz variables.
But on my home Domoticz, I would like to collect the speedtest results and show them in a Node-Red dashboard...
Opening MQTT or Node-Red to the outside internet is something I would like to prevent. Currently the only ports that are in the NAT are VPN and remote-Domoticz. Adding more ports is not something I look forward to...

A question that keeps coming back into my mind.
What is the rationale for Virtual Sensors not being sent across to the master Domoticz server? Is there a good reason, or was it simply never implemented before?
Also, is this true for all types of virtual sensors?

I cannot answer that question, but maybe some of the developers can.

You can try to publish the Speedtest results to your MQTT server from your Remote Pi and to subscribe to it with your Master Pi.

You have to open port 1883 on your router. On the other hand you can close port 6144.

I understand. But I have more devices and sensors for which I use the 6144 link.
It feels like a work-around..... I would much prefer to use the Domoticz sharing method.

To add to my confusion: I checked the sensors coming in on my central Domoticz, and noticed that the Raspberry Pi Motherboard sensors plugin actually uses a couple of General Custom Sensor devices. And they really do come through across the 6144 link!

So why are these sensors different from the ones that I create using the "create virtual sensors: button in the hardware tab?
