Hi all,

finally i rewrite a code for myself. There is no More EEPROM usage at all.
I'm using MajorDoMo (http://majordomohome.com/) and it more suitable for me to have a 10 minutes counts from Rain Gauge.

Here is my new code:

#define MY_RFM69_ENABLE_ENCRYPTION

/**
 * 
 Author: Sergey E. Yakovlev
 Date: 2017/02/25 u001
 
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

And now i able to see when it was a rain and how strong it was ;-)

@schmucke I'm using 5V 1Amp from tiny mobile charger https://www.thingiverse.com/thing:2171813

Enfeet

Ups! After 3 days.....

Enfeet

@dbemowsk Sorry, i m living in metric units ;-) But, i think it can be calculated logically. Just look at a DIY project: https://www.education.com/science-fair/article/DIY-rain-gauge/ The logic is to attach a scale to a bottle and measure the mm or inches of rain occured. Our goal is recalculate the number of impulses to the amount of precipitation depending on square of our bucket. So it's possible to take a bottle with the same square like our bucket, attach a scale (inches or mm does not matter) and let collect all water out of our measuring gauge i.e. take a litter or half flow it to a gauge and collect after. And finally just divide measured level of collected water to the number of impulses counted....
Sorry if method is not clear... ;-) I can draw an idea in a pictures ;-)

@Enfeet Precipitation intensity
"Strong" is called rain, if it drops from 15 to 49 mm in 12 hours. Precipitation is also "very strong" when it falls from 50 mm in 12 hours.
"Strong snow" - the amount of precipitation from 7 to 19 mm for 12 hours. "Very heavy snow," when its amount exceeds 20 mm in 12 hours.

Enfeet

@dbemowsk I think it's time to look in a book ;-) "The amount of precipitation is expressed in millimeters of a layer of water that would be formed from the precipitation, if they did not evaporate, did not seep into the soil and would not drain. Numerically, the amount of precipitation in millimeters is equal to the amount of kilograms of water left on the site in 1 sq.meter, i.e. 1 mm = 1 kg / 1 m2.

Enfeet

@Enfeet o! d=122 not 112... uff correct ;-)

Enfeet

@dbemowsk i use first found online calculator http://onlinemschool.com/math/assistance/figures_area/circle/
and... strange.... it gives other result ;-) So my calculations are incorrect ;-(
A = 1 4 π d2 = 1 4 π 1122 = 3136 π ≈ 9852.032512

Hi friends,

here is my replica of Rain Guage MySensors project
photos:
https://goo.gl/photos/4kA7T4d8SsDBRrrS7

The sketch is adopted for 'Adafruit Unified Sensor by Adafruit' + 'DHT sensor library' just uncomment both DHT_ON and DHT_ADAFRUIT
and last version of Arduino IDE 1.8.3

...and Yes, I'm using rfm69hw radio with encryption enabled ;-)

 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)

The arduino code is also from original project (https://www.mysensors.org/build/rain) but i adopt it to Adafruit Unified Sensors Library and last version of Arduino IDE 1.8.3

Hi friends,

here is my replica of Rain Guage MySensors project
photos:
https://goo.gl/photos/4kA7T4d8SsDBRrrS7

The sketch is adopted for 'Adafruit Unified Sensor by Adafruit' + 'DHT sensor library' just uncomment both DHT_ON and DHT_ADAFRUIT and Yes, I'm using rfm69hw radio with encryption enabled ;-)
3d bucket model: proposal to split it on a 3 part (i split on 2 parts now and have some troubles)

 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)
