Thanks for all answers.

Node 25 send its value every 30 second (before I said every 2 minutes)

So my conclusion is that GW is not sending ACK back to my repeater.

value 96637 has already been sent before so GW will not send ACK

7957760 TSF:MSG:READ,25-25-0,s=0,c=1,t=24,pt=5,l=4,sg=0:96637
7957766 TSF:MSG:REL MSG
7957806 !TSF:MSG:SEND,25-7-0-0,s=0,c=1,t=24,pt=5,l=4,sg=0,ft=0,st=NACK:96637

30 seconds later, now Node 25 sends new values(96638) that is different since last send, so this time GW will send ACK

7987763 TSF:MSG:READ,25-25-0,s=0,c=1,t=34,pt=7,l=5,sg=0:0.01
7987768 TSF:MSG:REL MSG
7987808 TSF:MSG:SEND,25-7-0-0,s=0,c=1,t=34,pt=7,l=5,sg=0,ft=1,st=OK:0.01
7987819 TSF:MSG:READ,25-25-0,s=0,c=1,t=35,pt=7,l=5,sg=0:96.638
7987825 TSF:MSG:REL MSG
7987829 TSF:MSG:SEND,25-7-0-0,s=0,c=1,t=35,pt=7,l=5,sg=0,ft=0,st=OK:96.638

30 seconds later, same values so GW will not send ACK

8017766 TSF:MSG:READ,25-25-0,s=0,c=1,t=24,pt=5,l=4,sg=0:96638
8017771 TSF:MSG:REL MSG
8017811 !TSF:MSG:SEND,25-7-0-0,s=0,c=1,t=24,pt=5,l=4,sg=0,ft=0,st=NACK:96638

30 seconds later, same values so GW will not send ACK

8047768 TSF:MSG:READ,25-25-0,s=0,c=1,t=24,pt=5,l=4,sg=0:96638
8047774 TSF:MSG:REL MSG
8047813 !TSF:MSG:SEND,25-7-0-0,s=0,c=1,t=24,pt=5,l=4,sg=0,ft=1,st=NACK:96638

or can it be that when it sends two values it will be ACK fro GW?

look at 7987763, this value is water flow
at 8017766 it is only the incremental value for my water meter, no flow is sent

This is a water counter node.
It will send the value every 2 minutes, even if there isn’t a new value.
But when we use water it will be a increased value, then I get OK from Controller.

@mfalkvidd said in Repeater getting NACK:

@flopp said in Repeater getting NACK:

Is looks like when the value is same as already sent, Gateway or controller is not accepting the value

I can't see anything in the posted log that supports this conclusion. Could you elaborate?

Node 7 can send and gets OK, but when Node 25 send its values it gets NACK.
When the value is new from Node 25 it gets OK

Could you grab a log from the repeater and node25 at the same time?

I will try

Could you post the sketch for node25?

Is node25 sending more data immediately after sending the meter reading? Maybe a second send causes a collision with the the message sent by the repeater.

I was thinking about the level that you define in beginning of sketch.

above is the DEBUG from my repeater.

Node 25 is a water meter. Is looks like when the value is same as already sent, Gateway or controller is not accepting the value, but as soon as there is a new value is get OK.

Anyone that seen this or can explain why this happens?

@flopp
Anyone?

@scalz said in Measure a node's NRF signal or distance value:

• I_POWER_LEVEL which is the internal msg for the TX radio powerlevel. To get a feedback on the radio power level set by ATC

I couldn't find I_POWER_LEVEL here, https://www.mysensors.org/download/serial_api_20#internal

Is this a command?

What I want to is to get the Set Level of nRF24. This is set in the sketch but when it has been sent to Arduino, I have no idea what I set that day.
eg. Repeater Node, I am using the example, make some changes, like PA_LEVEL, then I don't save the sketch

@mfalkvidd said in Sensebender gateway local sensor:

@deluka yes. Just use present() and send() as you would on a normal sensor node.

So when using send() it will send the data directly into my Domoticz, which I use as Controller?

I use Gateway Serial.

I have had very strange errors and I don't know what I found out.
I had a repeater with a nRF24 PA+LNA working good for about 1 year, suddenly this repeater causing that the GW got hanged, no data was received from any nodes.
I power off the repeater down, restarted GW and everything started to work normally.
Last week I took time to solve the problem, it was still annoying me!!!
Reprogram the same Arduino Nano and nRF with PA+LNA, worked for 2 days, then stopped.
Same Arduino Nano but changed to nRF24 without PA+LNA, worked 1-2 days then stopped.
Changed to Arduino UNO and nRF with PA+LNA, worked 2 days.
Arduino UNO and nRF24 without PA+LNA worked 2 days.

I was so frustrated and didn't had any idea. I had been running 2.3.0 on almost all my nodes, so I tried to change GW to version 2.3.1 and Repeater to version 2.3.1(Arduino UNO with nRF24 without PA+LNA) now it has worked for at least 1 week.

My Arduino Nano is fake and UNO is genuine.

Maybe you can get some help from this?
