When freshly connected to RFLink via RFLink Loader you should see the currently loaded firmware version on the 3rd line.
this shows communication via USB is working.
Activate debug mode and press a button on a remote control.. check if you see data appear.
No data when you press buttons means something is wrong.

I am using RFlink and Arduino Mega with Domoticz on my Synology NAS.
It is possible to read the unused analog inputs and/or GPIO of the Arduino in Domoticz, i.e.use these inputs as sensors?

If you can program a bit yes. Otherwise it will take some time to implement that. You can easily read a sensor value and put that true the serial (USB port) to your synology with domoticz in it.

Already received PCB from Nodo, soldered everything but when I added to Domoticz nothing happens. I just only see following log:

2016-02-02 23:56:38.573 RFLink: Using serial port: /dev/ttyUSB0
2016-02-02 23:56:39.493 RFLink: Controller Initialized!...
2016-02-02 23:56:39.569 RFLink Detected, Version: 1.1 Revision: 37 Build: 5

In the meantime I've tried several times to push the button of Elmes CH4HT remote but nothing happens.

I've connected Mega to my PC to enable debug and see if anything is being presented. Unfortunatelly only following logs are shown


20;00;Nodo RadioFrequencyLink - RFLink Gateway V1.1 - R37;
10;version;
20;01;VER=1.1;REV=37;BUILD=05;
10;rfdebug=on;
20;02;RFDEBUG=ON;

No matter if I leave radio (board) connected or unplug it the same logs are shown
Is the any possibility to check if radio is initialized correctly ex. with debug command?


I already checked soldered joints with multimeter so I have 99% sure that board is correctly assembled

Is is possible that my remote is not supported at all and RFLink is not able to catch anything?

As an antenna I'm using my old wifi router antena screwed to the onboard SMA connector

Make sure it works gnd on the board.
This remote control works, all the keys are seen as one

You were right artip. There was an issue with the GND supply.
After I short wired from Mega GND to the rflink board female socket GND it has started to work.

I'm wondering how actually GND should be supplied...?

Yes, domoticz is recognize only one button, but, I will provide debug data of all possible buttons to Stuntteam


I've also found that Domoticz is able to read only status of command sent by remote. Is it possible to send commands from Domoticz as an remote at all?

Elmes works with coding Keeloq, and I think the rflink can't send these codes.

Hi, what do i need to receive/transmitt 868 mhz signals? Ive received the "shield" yesterday, with the 433 Aurel transceiver,

A 868mhz transceiver... which device brand do you want to control ?
Domoticz stable 3.5877 for real & Domoticz beta for test

General 868 mhz components, I guess i need to buy Uzb1 or similar to control z-wave components, but got Nexa firedetectors from before i started with HA, and they run on 868 mhz.

Guess i need a new Arduino Mega, and RFLink Gateway shield for 868 Mhz transcevier?

I changed from pimatic to domoticz. I am now using the RFLink instead of the Arduino Nano and cheap super heterodyne transmitter/receiver. With my previous solution I could receive any remote anywhere in my house. With the RFLink and the antenne supplied with the kit from Nodo-shop I can't even receive a remote from the other side of my living room. I tried replacing the antenne with the simple wire I was using before. This actually improves the range but it not perfect. I tried adding an extra wire between the Mega board and the shield GND but that didn't make any difference.

Transmitting is no problem. Should I try a better antenna or shall I swap the supplied tranceiver for the two heterodyne transmitter/receiver??

In most cases, results with the Aurel transceiver are very good.
Since you have the components already, you could quickly wire the super heterodyne to see how that works for you.
Some wiring details are available here http://www.nemcon.nl/blog2/2015/07/aa

You should first check the modulation that your fire detectors use.. ASK or FSK..

I was expecting the Aurel with a proper design to work better. For this reason I was surprised. I noticed different 433Mhz antennas on Nodo Shop. So maybe the standard one that came with the kit was not the best one.

I will try to hook up my other receiver and report back.

Hate to say it:

I put my "old" transmitter and receiver on a breadboard. Connected Vcc and Gnd direct from the Mega to both (not as indicated via D15 and D16). The TX data and RX Data to D14 and D19. Simple wire as antenna. Transmitting is without a lot of testing "similar", that means all my wall-plugs switch on/off within my required range (house).

Receiving is a lot better!! I can now use a remote on the first floor and it is picked up by the Mega. The same with front/back of my livingroom.

It seems that switching Vcc with the D15/16 pins doesn't work as advertised. I will try to de-solder the transceiver to check it with a breadboard as well.

Update: Disconnected D15/16 from the Mega. I don't have a multimeter at the moment to measure the true output of D15. Should be 5v on a digital out, but I read that sometimes its less. So I connected 5v directly to those pin on the RFLink PCB. Didn't make any difference so most likely the digital output is as it should be.

Its GFSK according to the manual, whatever G stands for? Greater? :P
But how does this help? I need a 868 transceiver anyway dont I?

FSK is not (yet) support.. so you would need more than just a receiver/transceiver..

GFSK = Gaussian Frequency Shift Keying modulation, spectral width is limited due to filter.

Is there a possible ETA of implementation of the mysensor protocol to RF-Link.

I read that MySensors might be supported in a new release of the 'nodo' RF-LINK gateway package. The 2.4Ghz chip could already be put on top of the current module! Any idea when this update can be expected? Otherwise, we have to build the gateway ourselves and give up another USB-port from the Raspberry-pi.

Any recommendation on what PIR's to use with the RFLink 433MHZ? I am considering the Chuango PIR-900 however I see there are model 910 already. Are these better? Are there any others that does not cost to expensive? It would be nice to get a pet friendly option however this is not a deal breaker.
