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)
