Are Domoticz Devices transmitters or receivers (Newbie question)

[ArnieO]

I am new on this, so please bear with me.
I have a number of Nexa transmitters ("wall switches") and receivers (dimmers and on/off pods). I have installed Domoticz on a RasPi3 with an RFX433.
I have a probably very basic question: What am I controlling from Domoticz - the transmitters or the receivers? Or am I controlling receivers by mimicking the transmitters? I have some wall transmitters that control several receivers (lamps). They show up as separate Devices in Domoticz.
I have difficulties seeing the logic of this. The physical implementation is a function of numerous compromises, which I do not necessarily want to mimic in Domoticz, but I am sure this is taken into account by the designers, I just need some guidance.
Is it possible to identify individual transmitters and individual receivers (dimmer or on/off pods)?
What I would ideally want to do is program things like:
"When the ON is activated on the bedroom wall switch, only switch on the bedroom light. When OFF is activated on same switch, turn off also wardrobe light"
I would be very grateful in anyone could point me in the right direction, as I have not been able to sort this out with the documentation I have found so far.

Domoticz can both mimic your transmitters and use them as input signals. So you could define your logic within Domoticz.

It is possible to still let your transmitters controll your receivers, but then Domoticz may lose track of whether a reciver is turned on or not.

Thank you @Nerre for your rapid response.
I am totally fresh on Domoticz, so please be patient!
How do I identify and address individual transmitters and receivers?

So the way I have this setup using Byron/HomeEasy kit -

Tell Domoticz to "allow new hardware for 5 minutes in settings"
Press the learn button on the switches page and then press the wall switch ON. Your switch should now appear in the Devices page. Click the button to add this to Domoticz with a name - eg "Livingroom". Now whenever you press the wall switch your lights will turn on as they did before - and RFX433 will also see the signal and update Domoticz to say the lights are on. Click the switch in Domoticz and the lights should turn off.

Repeat this for every switch you have - and the wall switches and Domoticz will stay in sync (though sometimes RFX433 will miss the signal from the wall switch because of range issues, interference, etc etc - this is just something we have to live with because the 433MHz airwaves are as full as the 2.4GHz WiFi ones).

Is there a way to get the ON button on a transmitter to switch on one light, while the OFF button switches off more than one?

Hi ArnieO,
you can create a dummy switch (with off delay 1sec, push button) in the hardware and in Events you can create an script that turns off all your devices if you dummy switch is on

Kind regards

Hi Lebo2d9. Thank you for trying to help me - but I still do not understand how to accomplish what I want. Please see new thread where I try to be more specific in what I do not understand: http://www.domoticz.com/forum/viewtopic ... 28&t=17569
