@mfalkvidd many thanks for the quick answer!

Weirdly this behaviour only shows when I'm using the sleep mode. Also first time NACK appears is after the first Sleep - DEBUG after reset below, NACK at 8437. Any idea what i'm doing wrong or where i could fix it? many thanks in advance

@fausti
ok, I have solved it myself - the PIR made all that trouble.
I did connect the PIR on 3.3V (similar to https://forum.mysensors.org/uploads/upload-4bdca27e-3c36-4c68-9e54-947b9f4717b4.jpg).

Problem was, that when arduino wakes up the radio, the power drop would kinda restart the PIR, which causes an interrupt. Think a similar problem was discussed here:
https://forum.mysensors.org/topic/6511/hc-sr501-3-3v-randomly-sends-tripped-when-radio-is-on

Anyways - you surly would have helped, if i would not have found it. Great forum!

@Yveaux sensor is using standard NRF24L01+ (only the gw uses pa+lna - but I guess that won't be an issue?)

@tekka did you use the same sketch? You mentioned smartsleep, I haven't enabled that.. I'll try MY_DEBUG_VERBOSE_RF24 later, use a fresh NodeManager and will check all my hardware again and I still have to try that fix: https://forum.mysensors.org/topic/9598/smartsleep-wake-up-message-always-get-nack
I've build more than one sensor and all of them are showing that delay - using different power sources and I also tried different capacitor. Maybe after all it's the gw.. but can't think of a reason why sleeping would cause that behavior at gw.

I'll report later - Thanks for the quick help!!

@tekka WOW!! Your fix works like a dream - can't thank you enough!

For now I just used your patch at the sensor - but it allready runs perfectly - no lag/no NACK (see DEBUG below).
So the radio needs more time to settle? How long did you set the delay?

Many many thanks to @tekka and to you all for helping that fast and professional!!

[For so many hours I tried figuring out where the problem lies.. at least I know that library better now ^^ ]

@Yveaux sensor is using standard NRF24L01+ (only the gw uses pa+lna - but I guess that won't be an issue?)

@tekka did you use the same sketch? You mentioned smartsleep, I haven't enabled that.. I'll try MY_DEBUG_VERBOSE_RF24 later, use a fresh NodeManager and will check all my hardware again and I still have to try that fix: https://forum.mysensors.org/topic/9598/smartsleep-wake-up-message-always-get-nack
I've build more than one sensor and all of them are showing that delay - using different power sources and I also tried different capacitor. Maybe after all it's the gw.. but can't think of a reason why sleeping would cause that behavior at gw.

I'll report later - Thanks for the quick help!!

@mfalkvidd thanks again!!
Yeah.. went through the whole NodeManager Library, tried many things, but couldn’t find the reason for this behaviour. probably I must build my sketch again on foot – without NodeManager, hoped it could save me some time. ^^
PIN 6 powers an LDR together with PIN 5, read by PIN A0. But when I exclude all corresponding parts and even remove the hardware (10k + LDR) it won’t help.

Oddly sleeping Time (MCO:SLP:MS=20864000 has the same value as the number after NACK (st=NACK:20864000). If I change the sleep time (e.g. from 1 day to 60 sec) both values are changing equally to the equivalent value in ms.

@henrik-nielsen had a similar problem (maybe the same) https://forum.mysensors.org/topic/9598/smartsleep-wake-up-message-always-get-nack
Later I’ll try the fix described by @berkseo.

Thanks!

@mfalkvidd many thanks for the quick answer!

Weirdly this behaviour only shows when I'm using the sleep mode. Also first time NACK appears is after the first Sleep - DEBUG after reset below, NACK at 8437. Any idea what i'm doing wrong or where i could fix it? many thanks in advance

Hi I’ve build an Motion+Light Sensor (connected to openHab) and it works pretty well, except that there is a tiny delay (1-2 sec) between waking up and sending the message – which is a bit of a pain, since e.g. connected lights will turn on with an delay.

What I found out is, that the reason for the delay lies in the sensor itself – so no problems with the gateway. In the DEBUG of the sensor you can see TSF:TRI:TSB, and right there the sensor stops for about 1-2 seconds before sending it’s msg. (see picture below):

Do I need to change somthing in "MyTransport" in order to get rid of this delay -> “TSB “ (Set transport to standby)? https://www.mysensors.org/apidocs-beta/group__MyTransportgrp.html#ga2c5750b886bd43338e04cd4cb132e589

Or is there any other way - maybe I'm missing something (sketch down below).

Hope You can help - many thanks in advance

@fausti
ok, I have solved it myself - the PIR made all that trouble.
I did connect the PIR on 3.3V (similar to https://forum.mysensors.org/uploads/upload-4bdca27e-3c36-4c68-9e54-947b9f4717b4.jpg).

Problem was, that when arduino wakes up the radio, the power drop would kinda restart the PIR, which causes an interrupt. Think a similar problem was discussed here:
https://forum.mysensors.org/topic/6511/hc-sr501-3-3v-randomly-sends-tripped-when-radio-is-on

Anyways - you surly would have helped, if i would not have found it. Great forum!

Hi, I need some advice for my following problem..:

Situation: Arduino ist connected to an raspberry gateway with openhab -> works just fine.
To the arduino I have connected a PIR on 3 and a photoresistor (LDR) with an 10k resistor on A0 -> works just fine.
On first boot (after connecting etc.) the arduino sends motion status + LDR value. But after that first msg. only the motion (tripped) is send.
What I want: I want that the arduino sleeps until there is an interrupt comming from the PIR and then sends the motion status+light value (LDR) and then sleeps again 4ever until the next interrupt.
Problem: As I said, it only sends the light value only once.. and then never again. On the arduino debug I can see, that only motion is send:

PRES I=2 T=1 D=MOTION
READY

MY I=5 M=255
INT P=3, V=0
INT P=3 M=1
INT P=2 M=255
MOTION I=2 P=3 V=0
SEND D=0 I=2 C=0 T=16 S= I=0 F=0.00
LDR I=1 V=352 %=34 <-- first an last time LDR sends it's value
SEND D=0 I=1 C=0 T=23 S= I=0 F=0.00
INT P=3, V=1
MOTION I=2 P=3 V=1
SEND D=0 I=2 C=0 T=16 S= I=0 F=0.00
INT P=3, V=0

Hope you can help me many thanks in advance
