Request Orcon functionality in Domoticz

[84dasilva]

RFXcom868xl is able to communicate with Orcon (MVS-15H) in the windows test program.

Please activate this functionality in Domoticz.

I see references of Orcon in the source code (for Fans). I am no RF user so no idea how to select it in Domoticz.

[waltervl]

Do you see the Orcon Protocol when selecting Set Mode on your RFXCOM hardware gateway (menu Setup - Hardware)?

[84dasilva]

Hi, thanks for reply.

No the protocol selection functionality has been removed from domoticz. Also I don't see the required protocol as an option.

In the rfxmngr the orcon protocol is activated.

[waltervl]

Yes it seems this is the new way to not select it within Domoticz anymore. See also https://github.com/domoticz/domoticz/is ... 1518644890

So what is the issue? When you have set Orcon in RFXManager your receiver can work with that and should communicate with Domoticz.

The issue is that domoticz does not seem to work with the orcon protocol. It does not see any incomming devices. Devices which are seen in the rfxmngr tool.

I cannot find any other options to search or set any rfxcom868 device related settings in domoticz.

[waltervl]

Perhaps ask rfxcom directly how to do that.

He adviced to post the request here.

Also tried with RFXtrx. Received "Invalid data received!....".
But even after I changed the source code and commented out check for type pTypeFan, Domoticz detected new buttons per every Orcon button (if you press it). But they were not functional at all. While looking into Domoticz source code for Orcon support, it looks like the imlementation is not finished.

I found that the respons from a Orcon device is

Code: Select all

pLen == 0x11

but the Fan device in domoticz has

Code: Select all

pLen == 0x08

so if I make a change in RFXBase.cpp to

Code: Select all

case pTypeFan:
return (pLen == 0x08 || pLen == 0x11);

Then the code works and gives me a on/off switch.

But sometimes it is detected as a second device.
So with 1 remote I have 2 devices discovered.

The Hardware remote 15RF has 6 buttons.

So has someone another remote and does we have to make a separate Fan Device for Orcon (FAN2)

With my test setup I now have identified the different messages.

So based on this I propose a change from using RemoteID to using Destination ID as Hardware ID in Domoticz.

Leaves only the state off the device from the 6 buttons.

I also have an honeywell hgi80 transeiver, which operates on the same frequency/protocol.

It also notices messages received from the orcon.

2025-12-27 21:15:41.601 Error: EvohomeHGI80: Unknown command 31d9
2025-12-27 21:15:58.464 Error: EvohomeHGI80: Unknown command 31e0
2025-12-27 21:17:41.073 Error: EvohomeHGI80: Unknown command 1298

These messages seem to be status info received from the orcon Unit.

Does anyone here have the skills to add these message ids for decoding?

[homeJLB]

if your Honeywell HGI80 is connected to the same hardare as the RFX.

you can add

Code: Select all

_log.Debug(DEBUG_HARDWARE, "CheckValidRFXData: pLen=0x%02X, pType=0x%02X (%s), pData=%s", pLen, pType, RFX_Type_Desc(pType, 1), ToHexString(pData, pLen + 1).c_str());

just like

then you can see the HEX-code transmitted and received

Thanks for the quick response.

I need to find the time to look into this, this will be later in Januari.

Wil get back to it.

I have found that a FAN-device in domoticz is only correct displayed with a On/Off switch.
With a Selector Switch the Icon is empty.

Also when selecting the FAN as Favorite it is not shown on the Dashboard.

When I changed on the switch-page to selector-switch and add levels.

And when I press a button on the selectorswitch there is a mismatch from the ID
It changed from 772473 to 732473
So I believe the Write to Hardware is also a Problem.

I have changed in hardware/RFXBase.cpp

Code: Select all

case pTypeFan:
		return (pLen == 0x08 || pLen == 0x11 || pLen == 0x31);

and in main/mainworker.cpp

Code: Select all

	//      Make a switch for Orcon Device based on Destination ID
	if (pResponse->ICMND.subtype == 0x0C)
	{
		_log.Debug(DEBUG_HARDWARE, "Subtype Orcon detected");
		sprintf(szTmp, "%02X%02X%02X", pResponse->FAN2.did1, pResponse->FAN2.did2, pResponse->FAN2.did3);
		//"CustomImage", 8 FAN
	}
	else
		sprintf(szTmp, "%02X%02X%02X", pResponse->FAN.id1, pResponse->FAN.id2, pResponse->FAN.id3);

This to have the received switch with Destination ID.

I have found a solution for supporting the ORcon-FAN device.
I have made a Pull-Request on Git-hub.
