domoticz not read with raspberry or I do not know how to read temperature and humidity

fleinze

I am a domoticz user, but I have a serial gateway and did not try a direct gateway.
But I am sure your hardware-configuration is wrong.
You need to delete the entries no. 5 and 3 and add a "MySensors Gateway USB" with the serial port "/dev/ttyMySensorsGateway".
The actual sensors are not configured in the hardware-setup. If domoticz receives a reading from a new sensor, you can find the sensor in the devices-section.

If you are a beginner, I strongly recommend to start with a serial gateway!

revoltec112

hello I know but I have tried through the gate USB and also was not working , help me as you can, how you want your file ttyMySensorsGateway , I like it open in the nano this file is empty or perhaps me someone some idea how this is supposed to look , please , I really already sit on it week and nothing

I'm not sure, but I think I read somewhere on the Domoticz forum, that it's only possible to use the GPIO's, on the pi you're running Domoticz on, as digital output. I'm not even sure if you can use them as input.

But if you can hook a temperature sensor to it. I'm really interested in how you'd accomplished it.

here is the link to connect and for testing can be seen on the RPI data transmitted from the remote sensor but the question is how to do it domoticz read ???

revoltec112

whether in the / dev file must be named ttyMySensorsGeteway ? if so how it developed and what it should contain

mfalkvidd

I am not sure I understand your question, but I have a NRF24L01+ connected to my Raspberry Pi and I am able to read the sensors in Domoticz.

I had to do

sudo ln -s /dev/ttyMySensorsGateway /dev/ttyUSB20

because /dev/ttyMySensorsGateway did not show up in the serial port list on the Domoticz Hardware page. Then I added Mysensors to Domoticz like this:

I hope this helps

revoltec112

Please can you help me step by step how you did it

revoltec112

I made this command does nothing fortunately still does not work : ( ( (

mfalkvidd

Install the gateway:

git clone https://github.com/mysensors/Raspberry.git
cd Raspberry/librf24-bcm
make all && sudo make install
cd ..
make all && sudo make install
sudo make enable-gwserial
sudo /etc/init.d/PiGatewaySerial start

Verify that the gateway started properly:

cat /dev/ttyMySensorsGateway
0;0;3;0;14;Gateway startup complete.

Domoticz is unable to read from /dev/ttyMySensorsGateway so create a link to a name that Domoticz understands:

sudo ln -s /dev/ttyMySensorsGateway /dev/ttyUSB20

To automatically create the link on startup, add

ln -s /dev/ttyMySensorsGateway /dev/ttyUSB20

just before

exit0

in /etc/rc.local

I then added the gateway as per the image in my last post.

EDIT: Changed instructions to use librf24-bcm instead of tmrh20. tmrh20 tricked my Gateway into forwarding everything to a strange (non-existing) parent node.

@mfalkvidd I am attempting to follow your lead here on compiling the Raspberry mysensors gateway. However, this is failing on my rpi2 with tons of repeating errors like:
bcm2835.c: In function "bcm2835_init" :
error invalid suffix "x" on integer constant

I have enabled SPI from rasp-config. This is using the domoticz image of raspbian wheezy. Any thoughts on how to get around this?

mfalkvidd

@wergeld I remember seeing those errors as well. I think that's why I switched to tmrh20 but then I switched back and didn't get any errors when I tried again. Not sure what happened between, I hacked away now and then during several weeks.

wergeld

@mfalkvidd Okay, that is what i was going to go for as well:
Try tmrh20 and then see what happens.

I think there is some issue with the code in general as the rpi2 does not have the bcm2835 chip, right? I think it is bcm2836 (mind not working this early in the morning).

This thread might be useful for troubleshooting

wergeld

@mfalkvidd Yes, I used that to do the build initially. I cannot even get past the "make" command (tried sudo make as well). One person there had same error but they "solved it" and did not mention how they did it. I am going to give it another go tonight with a fresh image of raspbian.

wergeld

Finally got mysensors built on my RPi2. And have built domoiticz and it is up and running! I have added my USB gateway but now not sure what to do? It does not appear to pick up my sensor node. Where do I change the Gateway's channel and radio parameters?

wergeld

Actually forgot that MyConfig file when I built the RPi gateway. That is all set but now when I debug using ./PiGatewaySerial i see good output for the radio parameters but then it spits out continuous reams of:

read: 0-0-0 s=0,c=0,t=0,pt=0,l=0:
version mismatch
read: 0-0-0 s=0,c=0,t=0,pt=0,l=0:
version mismatch
read: 0-0-0 s=0,c=0,t=0,pt=0,l=0:
version mismatch

Not sure what this is about as I do not have any nodes on this channel (76). All my active nodes are on channel 90 and are talking just fine to my RPi running easyIOT server.

What is this version mismatch about?

GertSanders

Probably your nodes which were compiled with version 1.5 of the library, and the fact that the version of the library upon which the PiGatewaySerial is compiled is still version 1.4

On your Raspberry, in the Raspberry directory you should find a "Version.h" file.

Try changing the content to this:
/***

This file defines the Sensor library version number
Normally, contributors should not modify this directly
as it is manaaged by the MySensors Bot.
*/
#ifndef Version_h
#define Version_h

#define LIBRARY_VERSION "1.5"

#endif

The do another sudo make etc...

I hope this helps you.

GertSanders,
All of my nodes are using 1.4 library. Oddly at around 2:30 am my one sensor I moved to same channel as my domoticz gateway got picked up. Pretty interesting! I had changed it to the domiticz channel at 11pm. Progress is good. Now going to see about why the temp is being reported as ~140 F when that sensor reported ~70 F (correct) when attached to my other controller.
