@mfalkvidd : I think you have to change the condition in if too :
if (batLoop > 1) {
With that, batLoop = 2 when entering in the if (so the 3 values of the array are filled : 0, 1, 2), calculating the average and reseting the batLoop to 0.
If not modify, the array will be set with batArray[3] just before entering the
if (batLoop > 2) {
Other way is to set the batArray size to 4 values, and divide by 4 (I'm actually trying that).
@mfalkvidd Thank you.
I've found that too https://www.mysensors.org/apidocs/RFM69_8h_source.html
It's clearly indicated that DIO0 is IRQ.
So I think with "--my-rfm69-irq-pin=" it will do the job.
I'll test it as soon as i'll receive RFM69.
Thank you again
No no, my intention is just to send the pulse count, every 10 or 15 minutes, with battery powered sensor (and resend the last value even if it not change, due to domoticz not reporting heartbeat, but that is another story 
)
Hourly and daily value are ok for me.
I was using this sketch as an example just to see how it work and if it could directly do the job.
I enabled sleep_mode.
I was doing that with a testing arduino, directly connected to radio with jumper, and using jumper to simulate reed.
Each time I was doing a pulse that way, the node send the information directly. I was not understanding why. So I run a minimal sketch to try to understand, and I found this thread ...
Finally with all those informations, i think i'll do something like that:
Thank you again for this great help
Hello
Here is my last code for my gas meter. If it could help somebody

* The MySensors Arduino library handles the wireless radio link and protocol

* 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.

* Version 1.0 - Henrik Ekblad
* Version 1.1 - GizMoCuz
*
* DESCRIPTION
* Use this sensor to measure volume and flow of your house water meter.
* You need to set the correct pulsefactor of your meter (pulses per m3).
* The sensor starts by fetching current volume reading from gateway (VAR 1).
* Reports both volume and flow back to gateway.
*
* Unfortunately millis() won't increment when the Arduino is in
* sleepmode. So we cannot make this sensor sleep if we also want
* to calculate/report flow.

}```@evb it's for doing a gasmeter, counting with a reed sensor.
But for my tests, the read sensor is not connected. So nothing wakeup the interrupt.
I just send every 10 minutes the counter, as a keepalive. (Domoticz don't put the sensors as "red" )
First, I was doing test with newbie pcb, and I had strange values.
So I remove everything, and I do test with breadboard and dupont cable.
I just have the arduino pro mini, and the rfm69 solder on a nrf2rfm69 board and a 0.1uF capacitor.
I have 2AA alkaline battery, connected to the VCC/GND pin of arduino and to 3.3V/GND of NRF2RFM adapter.
I measure the current on the cable between battery + and 3,3V of NRF2RFM69 (like in your photo)
I have no scope, so I can't check NSS/MOSI/... and so on. But the transmissions are OK, and everything is working well, except current when sleeping.
I had no time today to do more test today. I will double check everything as soon as possible, try your sketch
Hello
Thank you for your time. Here is my complete sketch.
If arduino goes to sleep and wakeup and so on, I think that I'll see lot of messages sended.
I suspect my RFM69 to have some quality problems. But i'm not sure. I'll try to change it. as soon as i will receive new one from china.

Re: RFM69 sleep mode
Hello
I'm back with my high current in sleep mode. After changing my multimeter, challenging my arduino configuration, doing lot of test loosing my hairs, i finally found that it is my rfm69w that consume 2mA in sleep mode.
I use
#define MY_RADIO_RFM69
#define MY_RFM69_NEW_DRIVER
to configure RFM69
I sleep wit the sleep functon
int8_t cause = sleep(digitalPinToInterrupt(DIGITAL_INPUT_SENSOR), FALLING, 600000);
I measure the current directly in the 3.3V of the rfm69. In the meantime, the arduino mini is less than 50uA.
What could I do debug such a situation ?
Thank you for your help
Thank you for your answer
I'm trying to compare with only pro mini and rfm69 on a test plate, and 2 AA batteries. I have strange result, and i'm doubting about my multimeter.
I'll continue testing and will tell you
Re: 
Easy/Newbie PCB for MySensors
Hello
I'm building a gas meter sensor with easy pcb, with 3.3v / 8mhz arduino pro mini, a rfm69w (with an nrf2rfm adapter).
I remove led and voltage regulator on the arduino board.
The easy pcb is configured with battery booster and voltage divider (1mohm and 470kohm).
I use internal pullup to get read sensor of the gas meter (pin 3 used with interrupt)
Everything is working fine, but when sleeping, my multimeter said 400uA.
In the main time, I have this board from aliexpress, and with the same sketch use 40uA (ten times less), with a voltage regulator included and 16mhz clock
https://fr.aliexpress.com/item/33006101437.html?spm=a2g0o.productlist.0.0.1424881cHzQI0F&algo_pvid=16f38802-af52-43e2-a2d1-7e3c2a84733f&algo_expid=16f38802-af52-43e2-a2d1-7e3c2a84733f-0&btsid=2100bb5116098762728804034e5d33&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_
Is it normal ? Is it Arduino pro mini that consume much more than the development board? is there a special way to investigate it ?
Thank you for your ideas and advice.
@sundberg84 thank you again. I'll do like you say
@bjacobse I've seen them, but as @sundberg84 asked me, it's already finished booster, the one linked in mysensors store.
I'm looking something like the one used on Easy/Newbie PCB.
Can I use something like "Conn_01x03_MountingPin" ?
I'm starting kicad, I already have used easy/newbie pcb for my first sensors, but I need to design a board for an existing raingauge not working anymore (used by an old meteo station). I want to keep the mechanical part, and replace the electronical board.
Thank's for your help
Hello
Does somebody have library for dc-dc step up booster please ?
@mfalkvidd Thank you.
I've found that too https://www.mysensors.org/apidocs/RFM69_8h_source.html
It's clearly indicated that DIO0 is IRQ.
So I think with "--my-rfm69-irq-pin=" it will do the job.
I'll test it as soon as i'll receive RFM69.
Thank you again
