MySensors weather station

[dbemowsk]

@gohan So am I correct in assuming that an interrupt will wake a sleep timer? As long as I can catch the pulses from the anemometer, I don't see a reason I couldn't use a sleep timer. Just thinking about it, I may also want to use an interrupt for the rain gauge sensor for similar reasons. Not sure about the wind direction sensor.

[dbemowsk]

Here are a few more pictures of the new layout with the new anemometer cups.

[gohan]

@dbemowsk basically you would need to attach sleep to both interrupts on pin 2 and 3 and use them for anemometer and rain meter. For wind direction check it when it wakes up

[dbemowsk]

So I am trying to figure out code for the wind speed sensor and I see there is a V_GUST value. I am wondering what people use for that value.

[dbemowsk]

So now that I have the wind direction sensor working, I need to try to migrate the code into my weather_station sketch. One option that I am working on implementing is a calibration button for North. So after I get things set up and mounted, I will use a compass to point the wind vane towards North. I will then press the calibration button which will save the current direction position to EEPROM if it is different than the one stored. The following code will then be used to get the true direction that the wind vane is pointing.

value = 360 * myAS5047.sensor_read() / 16383; //Read the value from the direction sensor as a value from 0 to 360
north_offset = EEPROM.read(address);  //Read the offset value from EEPROM

dir = ((value - north_offset) < 0) ? 360 - abs (value - north_offset)  : value - north_offset; //Get the true direction
/*
insert code to read the button and if pressed, check the current value stored in EEPROM against the value read from the sensor
and write the new value if it is different.  If the sensor value matches the current stored value, then ignore the write to
save on EEPROM writes.
*/

So with this idea, I will need to know a few things. First, I am assuming that MySensors does EEPROM writes and reads. Is there a particular addreess pointer variable that I should use when writing my value to EEPROM? I will also need to know how I can get the address pointer to that data the same each time the arduino is reset, especially if MySensors does writes and reads.

As always, any input is appreciated.

Hello, @dbemowsk
You should use the built in method from the MySensors library to do that :
https://www.mysensors.org/download/sensor_api_20#saving-state

[dbemowsk]

@Nca78 Thanks, exactly what I wanted to know.

[dbemowsk]

@Nca78 So my values are from 0 to 360, looking at the link you posted, the value that you save to an address is uint8_t which is equivalent to a byte (0 to 255). Is there a way to store a word value (uint16_t), or do I need to break the value into two bytes and store those into two positions?

[Nca78]

Yes it can only store bytes, but it's not a big deal to make a method to read/write values on 2 bytes.
Else you can just keep a precision of 2° and divide by 2 to get a 0=>180 value ;)

[dbemowsk]

Actually thinking about this, I should be using 0 to 359. 0 to 360 is actually 361 positions, not 360.

[gohan]

Precision of 2° I believe it's enough as many weather stations provide just the 8 general directions

[dbemowsk]

@gohan It would only be for saving the offset for north, so I think I will do that.

[dbemowsk]

So I am trying to figure out the SPI for the wind direction sensor. Where is the SPI code for MySensors. Do I need to call SPI.begin()? Does MySensors code use transactions? If so, where can I find that to look at.

[gohan]

Doesn't it have a library?

[dbemowsk]

@gohan It does, but it is an untested library. This is the test code that I ran using that library:

#include "AS5047.h"
#include <SPI.h>
#include <EEPROM.h>

#define SWITCH_PIN 7 //The north calibration switch

AS5047 myAS5047(5); // SS pin
 
int address = 0;      //EEPROM address counter
int north_offset = 0;
long value;
int dir;
bool button;

void setup()
{
  SPI.begin;
  Serial.begin(9600);

  pinMode(SWITCH_PIN, INPUT_PULLUP);

  north_offset = EEPROM.read(address);
}

void loop()
{
  value=(360*myAS5047.sensor_read())/16383;
  dir = ((value - north_offset) < 0) ? 360 - abs(value - north_offset) : value - north_offset;
  
  Serial.print("measured direction: ");
  Serial.println(dir);
  Serial.print("north_offset: ");
  Serial.println(north_offset);

  button = digitalRead(SWITCH_PIN);
  north_offset = EEPROM.read(address);
  if (!button && north_offset != value) {
    EEPROM.write(address, value);
    north_offset = value;
    Serial.println("Button pressed");
  }
  
  delay(1000);
}

This test worked fine, now I am trying to merge this with my weather station sketch. I am not very familiar with working with SPI. In the setup() method, they call SPI.begin(). I am just trying to figure out what I need to do for merging the code.

[dbemowsk]

Should all of the SPI stuff be included in the library?

[dbemowsk]

So now I have the direction sensor on the SPI bus with the CS pin connected to D5 on my easy newbie board. If I run my sample program for the direction sensor to test it on the bus with the nRF24 radio, I get readings and it seems to work fine. The problem is, if I run my modified rain sensor sketch seen below, I cannot get the radio to work.

 Arduino Tipping Bucket Rain Gauge

 April 26, 2015

 Version 2.0

 Arduino Tipping Bucket Rain Gauge

 Utilizing a tipping bucket sensor, your Vera home automation controller and the MySensors.org
 gateway you can measure and sense local rain.  This sketch will create two devices on your
 Vera controller.  One will display your total precipitation for the last 5 days.  The other, 
 a sensor that changes state if there is recent rain (up to last 120 hours)  above a threshold.  
 Both these settings are user definable.

 There is a build overview video here: https://youtu.be/1eMfKQaLROo

 This sketch features the following:

 * Allows you to set the rain threshold in mm
 * Allows you to determine the tripped indicator window up to 120 hours.
 * Displays the last 5 days of rain in Variable1 through Variable5
   of the Rain Sensor device
 * Configuration changes to Sensor device updated every hour
 * Should run on any Arduino
 * Will retain Tripped/Not Tripped status and data in a power interruption, saving small amount
   of data to EEPROM (Circular Buffer to maximize life of EEPROM)
 * LED status indicator
 * Optional Temp/Humidity (DHT-22 or DHT-11) and Light LUX (BH1750) sensors. To use, uncomment
   #define DHT_ON  and/or #define LUX_ON
 * Optionally send total accumulation of each day's rainfall or send only individual days rainfall totals.
   Uncomment #define USE_DAILY to display individual daily rainfall.  If it is commented out it will display
   a cumulative total rainfall (day4 = day1+day2+day3+day4 etc)

These are the errors that I get when I try to run the code:

Starting sensor (RNNNA-, 2.0.0)
TSM:INIT
!TSM:RADIO:FAIL
!TSM:FAILURE
TSM:PDT

If I disconnect the direction sensor and start it, the radio works fine. The odd thing is that when I run the test code for the direction sensor with the radio connected to the bus, that works fine.

Any ideas?

@dbemowsk my guess is your sensor tries to communicate on the SPI bus and prevents communication with NRF24.
I don't know what is in you AS5047 files so I'm not sure but I suppose it's taking over the SPI bus at creation, you should try to force the CSN pin used for the as5047 to HIGH in before() method to disable it before MySensors library starts using the radio.

[dbemowsk]

@Nca78 ok, so I tried adding this:

void before()
{
  digitalWrite(AS5047_CHIP_SELECT_PIN, HIGH);
}

This seems to now allow the radio to connect, but I am still having some trouble. I then tried removing setting the CSN pin high in the before(), and adding it to the constructor of the library class here:

AS5047::AS5047(uint16_t SelectPin)
         : _ss(SelectPin)
{
         pinMode(_ss, OUTPUT);
         SPCR = (1<<SPE) | (1<<MSTR) | (1<<CPHA) | (1<<SPR1) | (1<<SPR0); // slow down clock speed, set up spi
         digitalWrite(_ss, HIGH); //<<-------------
         SPI.begin();
}

This seemed to do the same as putting it in the begin() method, but still having some trouble. I am going to see if I can work through the problems on my own, but I may post if I have questions. Let me know if you see problems with what I did to the class.

Thanks.

@dbemowsk it's good practice to have a pull up resistor on each SPI CS line (approx. 10k).
It can save you a lot of hassle when multiple devices share the same SPI bus.
