Domoticz as controller **and** a gateway for MySensor nodes running on a Raspberry Pi 2
-
This is interesting stuff! Do you know if the raspberrypi port supports rf69 as well?
-
@Anticimex: no idea. I have not used the RF69 so far. Still a lot to learn from the "classic" nrf24l01+ :-).
But if the same pins are used in the same location, then I believe it depends on the software. The SerialGateway software for Raspberry. Maybe one of the original designers of that gateway can tell you if they support RF69. Would be nice !

Here is an image of the voltage regulator I use:
SOT223 package, more then powerful enough for a single SMA-type NRF24.

@GertSanders Thanks for the extra info - that was very helpful.

some more images

Hi @GertSanders, I've received the PCB, built the adaptor and the software as per the MySensors Raspberry Port GitHub. I've created a symlink to /dev/ttyMySensorsGateway (/dev/ttyUSB40), which Domoticz, and I see the following in the Domoticz log:
2015-09-29 17:48:40.503 MySensors: Using serial port: /dev/ttyUSB40
2015-09-29 17:48:40.503 MySensors: Gateway Ready...However, I can't see any of the devices on my node - any ideas?
-
In my case I had to restart the nodes, because they did not get the ID from Domoticz. But it takes a few minutes. The gateway is polled every 30 seconds or so. Apart from that, I do not know what could be the problem. Did you allow discovery/addition of new sensors in Domoticz ?
The board should sit between pin 17/18 and 23/24 of the GPIO. There is not much on the board that could malfunction, except maybe the power regulator. Does it give 3V3 ?
Did you solder the jumper right?
If you solder close to the regulator, the board expects connection to 5V (as in my pictures). If you connected the 3V3 side, then it takes power directly from the GPIO. With the large NRF24 that could be insufficient.If all fails, then test without the board: connect the radio directly to the GPIO. That is all I can think of without seeing your setup.
-
Thanks, Gert. I've checked all my soldering (continuity from header to header), the jumper is soldered for 5V, and I'm getting 3V3 across the supply pins of the radio. Board is sitting between 17/18 & 23/24.
I'm still only getting the above 2 lines in the log, i.e., no devices.
I'll try connecting the radio direct to the GPIO later today. -
Cracked it! I'm using an RPi 2, and cat /proc/cpuinfo gives a01041 as hardware version. According to GitHub readme, CE needs to go to pin 15, not 22.
Now working with radio connected directly, but will now need to connect a jumper wire from the adaptor board.
-
Strange, I'm also working on the RPi 2. I will check what I have in my RF24 library, because I'm sure that you can change pin assignment in software instead of needing to resort to extra jumper wire.
When home I will check this tonight. I really need to write out a procedure for this, or we will forget in the future how it should be set up. -
Hello @GertSanders, for the time being I've got the gateway working with CE connected to pin 15, having carried out some 'surgery' to the board!
I've found this code in PiGatewaySerial.cpp (line 198 onwards):
/* create MySensors Gateway object */
#ifdef __PI_BPLUS
gw = new MyGateway(RPI_BPLUS_GPIO_J8_15, RPI_BPLUS_GPIO_J8_24, BCM2835_SPI_SPEED_8MHZ, 1);
#else
gw = new MyGateway(RPI_V2_GPIO_P1_22, BCM2835_SPI_CS0, BCM2835_SPI_SPEED_8MHZ, 1);
#endifIs this the 'offending' code?
-
Yes, as the rpi2 is not recognised properly the code compiles for rpib+.
I changed the code so that both rpi b+ as rpi2 have the same: use pin 22
-
@MikeF said:
gw = new MyGateway(RPI_V2_GPIO_P1_22, BCM2835_SPI_CS0, BCM2835_SPI_SPEED_8MHZ, 1);
You will need the code as here above, then no need for surgery
-
Had some time to log into my Raspberry 2 today, and indeed I adapted the code I used for the PiGatewaySerial because a RPI2 is not recognised properly.
So here is what I used as source-file:
I'm not sure where the correction should be made so that the RPI2 is recognised properly (instead of being recognised a s a raspi B+)
-
I will need to document this. In the original post I followed to compile the gateway for rpi, this was also mentioned.
I would prefer that the code is corrected in the right place, because I feel the RPI2 should be recognised properly.
Anyway, happy to know there is a +1 user with a raspberry 2 and direct connected NRF24. -
That's the code change I made (makes the 'if' redundant).
I've also changed the tty name (to /dev/ttyUSB40 - which is what I've declared to Domoticz) in this file and in Makefile.
BTW: Very impressed with OSH Park - got the PCBs here in UK (from US) 13 days after ordering!
-
This was the fourth board I ordered from OSHPark. For boards with ENIG finish, they are cheap. And the quality is indeed excellent. I have ordered a fifth design from them (should be ready end next week) and at the same time I sent my files to DirtyPCB. We will see what that gives quality wise. On this forum someone mentioned Shenzen2u and they are eaven cheaper then DirtyPCB. So my next design will also be ordered from those guys.
Now it's time to enjoy a local brew :-) -
@GertSanders Check out http://pcbshopper.com/, there are places slightly cheaper than DirtyPCB and places that will do runs of 5 boards instead of 10 for the same price per board. http://www.elecrow.com/ looks really good (5 boards for $15 delivered) but I haven't ordered from them yet so I can't comment on quality (other reviews of them say it's fine though).
-
I would rather pay 8.90 USD for 10 boards, then 15 USD for 5 boards delivered. http://www.shenzhen2u.com does the thing for me.
