[Newbie] Vera barometric sensor detection
-
Hi,
I think the Value is the pressure in Pa...
Maybe you can divide it by 100 to turn it in Hpa to let it working with Vera...
You can see the comment on the bottom of the page..

Hi,
thanks for the replies.
In fact, my problem is the detection of the sensor by my Veralite.
The 98828 number is the pressure, and on my pc connected by USB the sensors retrieve good values (temp + pressure) by the vera plugin doest not detect the sensor.Thanks.

I actually looked at the code you posted above now.
You seem to have mixed up things a bit. For sensors you must use Sensor or Relay-classes. Not Gateway. Gateway should only be used for the the gateway.Please look at the provided examples on http://www.mysensors.org.

@hek you are right, because I thought it was necessary.
As I mentionned I'm newbie on arduino, so I don't really know what is necessary or not so I tried to make a mix of the sketchs.@hek sorry for my long absence but I did'nt have much time to spend on it.
I tried from scrash the inclusion of my baromtere sensor, following your tuto
1 = upload to my USB arduino the original ArduinoGateway sketch
2 = plug my arduino to my vera using USB hub
3 = upload files plugin to my vera
4 = create the device
5 = configure the serial port for the new module
6 = reload vera twice and then the module appear with the lib version (1.3b3)
At this time I'm able to click on the "Start" button but of course no sensor is detected
8 = unplug my arduino, plg my barometer sensor to my arduino,
9 = load the BMP085 Barometric Pressure & Temp Sensor sketch changing only the baud rate (9600 to 115200)
10 = test on my PC work fine (I get temp and barometer values)
11 = plug my arduino to the VERA
At this time the "Start" button doesn't work any more, even after many reload of my veraI guess I'm missing something but I don't see what.
Thanks for your help. -

Thanks for your help.@javier Do you have a USB Gateway AND an Arduino Sensor with the BMP ... two separate devices linked by radio. It SOUNDS like you are trying to run the Baro sensor on the Gateway?

Hi,
I'm trying to make my vera lite detect my barometric sensor BMP085 (Bosch model).
the following skecth work fine using arduino ide but my vera refuse to detect it:/*

- DESCRIPTION
- The ArduinoGateway prints data received from sensors on the serial link.
- The gateway accepts input on seral which will be sent out on radio network.
- The GW code is designed for Arduino Nano 328p / 16MHz
- Wire connections (OPTIONAL):
-
- Inclusion button should be connected between digital pin 3 and GND
-
- RX/TX/ERR leds need to be connected between +5V (anode) and digital ping 6/5/4 with resistor 270-330R in a series
- LED purposes:
-
- RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
-
- TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
-
- ERR (red) - fast blink on error during transmission error or recieve crc error
*/

}Here is my vera plugin
Thanks for your help !
@javierhttps://github.com/empierre/arduino
you can take mine which is pressure sensor
-
@epierre thanks but I guess I misunderstood some basics : I guessed I only needed ONE arduino nano USB + sensor pluged on it and the vera plugin to get sensor data retrieve by vera lite.
This is right ? or do I need more than one arduino ?sorry for my dummies questions :-)

@javier clearly here your gateway has no radio... and all mysensors is about having wireless sensors speaking to a controller (e.g. the vera) through a wirelessgateway (the gateway).
I guess that if you don't want radio, you should write to the serial port the data in the form of the gateay, but don't need the gateway. That could be a bit complicated but not impossible.

@clippermiami in fact I have my arduino nano and pluged in y pressure sensor.
The arduino nano is pluged into my Vera
@javier the design principal is an
-
Arduino Gateway connected to the Vera, either directly over USB or indirectly via Ethernet; no sensors are attached to the Gateway;
-
Each Arduino Sensor Node has the various sensor devices and talks to the Gateway over a wireless connection
I vaguely recall there has been some discussion of attaching Sensor devices to the Gateway but don't recall that ever went anywhere.

@clippermiami the conclusion was that the sensors may make the gateway miss some messages...
z-wave - Vera -> Domoticz
rfx - Domoticz <- MyDomoAtHome <- Imperihome
mysensors -> mysensors-gw -> Domoticz -
