I am using version 1.5.?
I have not opened the rain-box for at least 4 month and not changed the code.
Maybe this error have been there since day one but I have not checked so often.
But now I am checking daily because of other nodes that I added recently and then I noticed this -

@flopp What other types of nodes is this happening on? I'd definitely suggest updating to the latest version of the Beta code if you're having interrupt issues.

As for myself, I'm using an over-simplified version of your code (https://github.com/mysensors/NodeManager/blob/v1.5-dev/NodeManager.cpp#L585) but the principle should be the same I hope (btw I didn't have the chance to tell you what a great project you put together!). I'm with the latest beta release but since using the arduino's attachInterrupt() in a non-sleeping board, the mysensors' library should not have an impact in my scenario I guess.
Something I want to check that may cause my issue I think is the power supply. I have a (chinese) USB wall plug connected to a (chinese) USB TTL connected to my arduino board. I wonder if a fluctuating power would generate this behavior (while indoor, it was connected to a different power supply). I'll try this way and report back.
Out of curiosity those are the logs from my controller (0.11 is 1 interrupt). So this is happening at every hour, up to 9 times per hour so the heat cannot be the issue I might say:

I had fake interupts on my device - would work great on test bench then with a 5v dc converter that was noisey plus a longer cable to the bucket I was getting a lot of trips. My fix which solved all the issues was a 0.1uF ceramic cap from ground to the signal pin of the bucket (right at the adruino) coupled with an inline resistor 330ohm to the bucket and a 1Kohm resistor from +5v to the signal pin. This is a basic pull up and debounce system and it manages to hold the 5V via the cap with 100% reliability thus far for 3 weeks including a lot of rain over the last few days. I would draw a circuit diagram if someone could tell me the best program to use?

@itbeyond cool thanks! I'll try to put together something similar and report back the results. I guess in this way you don't need INPUT_PULLUP when setting up the pin since already there right? Thanks
@user2684 Yes make the line:
pinMode(TIP_SENSOR_PIN, INPUT);I did make one other modification of installing an RF Choke and cap circuit on the input power supply but I am sure the cap & resistor mods made all the difference. Good luck and let me know how it goes!

@itbeyond I don't know if it's the best but I use Fritzing to do my diagrams. It is very easy to learn and easy for new people to understand.
@user2684 I am powering my with a good power supply and I believe it's on the vcc pin (not using the ftdi adapter). Maybe you want to try that?
@flopp based on what others are saying here I suggest you try changing the power supply as well. Also, are you powering the radio from the arduino or from the power source? If you don't have one already I would add a 100uF capacitor on the radio.

@itbeyond I've put together today the changes you recommended to my project and see what will happen overnight and tomorrow before moving on and considering replacing the power supply. So far so good since during the last 4 hours I had 0.00 which never happened 4 times in a row so far before applying the resistors and the cap. Btw, my project is 3.3v powered and not 5v like yours, should I use different resistors/capacitors. I'm asking because I'm not 100% sure how you got there ;-) Thanks!

@user2684 Those values should be ok - maybe the 330 inline with the switch could be a little smaller but it should be fine with all those values. See how you go.
I kept my noisy power supply after making these and an RF Choke mod. The RF Choke if you are interested is a 330uH choke inline with the power supply and a cap at 22uF (I used electro) on the inbound power supply just as it hits the board.
Good luck and do let me know how it is going. I am sure it will sort it.

@itbeyond I can say it is working perfectly now, thanks! Always 0.00 during the night, I force two triggers this morning and I had the correct equivalent of rain.
@petewill I'd add this as a note on https://www.mysensors.org/build/rain, even if it is not a common issue, at least for those who will experience it can have a solution ready to use.
So if I understand correctly (which rarely happens), in a no rain situation it is like the bucket is unplugged and the pin is connected to Vcc through the 1k resistor (to limit the current right?) and also charging the capacitor. When it rains, it is like the bucket would connect the input pin to ground and I guess the capacitor and 330R resistor would smooth this so to actually debounce the signal. Is it the case? Thanks

@user2684 That is great news - your understanding is basically correct. When no rain the 1K is providing the pull up to 3.3/5v and charging the cap at the same time (current limit is really for when you go to ground not to hold the pin up). When the bucket tips the cap is discharged via the resistor to ground (bucket switch) and thus the pin goes low. Yes - simple and effective pull up and debounce system which works every time - in fact I use this on all interrupt triggered pins for all my projects.
@petewill it would be good to include something like this on most of the projects, would have saved me a lot of early angst in having faulty triggered interrupts. I suspect different cloned Arduino boards have different to zero internal pull ups (3 different ones I have tried seem to have none) and to be 100% sure it is much better to document an external arrangement. It will really help the beginners to get it right first time and keep some hair regardless of the quality of the board they are using. I needed this on my irrigation controller also - same problem with a 10cm cable to a push button.

Interesting. I haven't experienced this behavior with any of my devices yet. I do power most of my sensors with my whole house power supply though so I guess that would explain it.
I will update the rain gauge page and also add this info to the troubleshooting section. Thanks for your help with this!
If anyone needs a visual of what @itbeyond described above here is the wiring diagram.

Hi friends,
here is my replica of Rain Guage MySensors project

#define MY_RFM69_ENABLE_ENCRYPTION /* 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.

Hi friends,
here is my replica of Rain Guage MySensors project
photos:
https://goo.gl/photos/4kA7T4d8SsDBRrrS7The 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 ;-)
#define MY_RFM69_ENABLE_ENCRYPTION /* 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.

@Enfeet What type of sensor did you use for the tipping bucket? Reed switch? Hall effect sensor?

Hi friends,
here is my replica of Rain Guage MySensors project
photos:
https://goo.gl/photos/4kA7T4d8SsDBRrrS7The 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 ;-)
#define MY_RFM69_ENABLE_ENCRYPTION /* 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) by @BulldogLowell and @PeteWill for free public use */ // Enable debug prints to serial monitor //#define MY_DEBUG //#define MY_DEBUG_VERBOSE #define MY_NODE_ID AUTO // Enable and select radio type attached //#define MY_RADIO_NRF24 #define MY_RADIO_RFM69 #define MY_IS_RFM69HW #define MY_RFM69_FREQUENCY RF69_433MHZ #define MY_RFM69_NETWORKID 100 #define MY_RFM69_TX_POWER 31 #include <math.h> #include <TimeLib.h> #include <MySensors.h> #define SKETCH_NAME "Rain Gauge" #define SKETCH_VERSION "2.0" #define DWELL_TIME 40 // this allows for radio to come back to power after a transmission, ideally 0 //#define DEBUG_ON // Rain gauge specific debug messages. #define DHT_ON // uncomment out this line to enable DHT sensor // 20170621 by Enfeet #define DHT_ADAFRUIT // uncomment out this line to enable DHT with 'Adafruit Unified Sensor by Adafruit' + 'DHT sensor library' //#define DHTTYPE DHT11 // DHT 11 #define DHTTYPE DHT22 // DHT 22 (AM2302) //#define DHTTYPE DHT21 // DHT 21 (AM2301) // /20170621 by Enfeet //#define LUX_ON // uncomment out this line to enable BH1750 sensor //#define USE_DAILY // Uncomment to display individual daily rainfall totals in the variables sent to your controller.

Enfeet@Enfeet I was checking out your sketch and was confused on some of the numbers you had commented into your sketch. I am gathering that they are numbers you used to figure out your CALIBRATE_FACTOR number, but I am trying to understand them. These are the numbers I am referring to:
//d=112 mm //11689.863832 mm2 = 116,89863832 cm2 //42,77209787776081 mm //88 89 91 91 90 = 89,8 //0,4763039852757329I am assuming that 112 mm is the diameter of your catchment funnel. I cannot however figure out your next number 11689.863832 mm2. What formula did you use to come up with that number? Knowing that may help me understand the rest of the numbers.
