@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

@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
@mfalkvidd I don't know what DI00 is, and if it's equivalent to IRQ ? If Yes, it's exactly what I need ! Thank you !!! I will test it as soon as I get my RFM69
Here is the pin mapping between RFM69W/NRF24 and Arduino/Raspberry
Arduino mini - NRF24 - RFM69 - Raspberry GW NRF - Raspberry GW RFM
9 - CE - N/A - 22 - N/A
10 - CSN/CS - NSS - 24 - 24
13 - SCK - SCK - 23 - 23
11 - MOSI - MOSI - 19 - 19
12 - MISO - MISO - 21 - 21
2 - IRQ - DI00 - 15 - 22
So, the only mismatch breaking pin compatibility (and preventing to use adaptors on the raspberry pi gateway) is on IRQ/DI00. Adaptors wire RFM69 DI00 on NRF24 IRQ pin, but they don't use, by default, the same pin on raspberry, depending the radio type.
@gohan Sorry I miss your answer a few days ago
I don't want to a gateway with both rfm69 and nrf24..
I'm planning to change my nrf24 sensors with rfm69, to have a better transmission distance. My two nodes are outside, and i have communication trouble if i put them where i wanted, specially for my rain gauge.
So I wanted to use those adaptors https://www.openhardware.io/view/16/NRF2RFM69.
I received them, and I'm still waiting RFM69 board to test it.
But as the pinout is not the same between nrf24 and rfm69 on raspberry gateway, I could not use the adaptor on the gateway. So before making a new board for my raspberry, I wanted to know if it's possible to change the default pin configuration, to have exactly the same as nrf24, and use an adaptor on the gateway too.
For that, I "just" need to redefine DIO0 on pin 15 (default is 22). So I wonder if it's possible to do it.
And "bonus question", I'd like to know why pin configuration is not the same between arduino and raspberry. Why pin 15 is not used for DIO0 on raspberry (equivalent to pin 2 on arduino). I'm telling myself it should be a good reason, but I don't get it.

Hello
I think there is a mistake in your code (on github) to mesure battery.
The array have 4 values, but you divide by 3. So you get to high result.
https://github.com/sundberg84/HomeAutomation/blob/master/BatteryMeasurer/BatteryMeasurer.ino
On line 77
Everything else is ok in my case the board works well with 2 battery AA, and 47uF cap (not with 4.7uF) .
Hello
Is it possible to redefine pin used for DI00 with rfm69 (with configure option for example) ?
Indeed, DI00 is on pin 22 on raspberry, and pin 2 on arduino.
But with NRF, pin 2 on arduino is for IRQ, which is connected to pin 15 on raspberry.
So if it was possible to force pin 15 for DI00, we could use adaptator card like this one https://www.mysensors.org/hardware/nrf2rfm69.
