Let's make it more simple.
I will have 100 nodes in my property which I don't want to preset with static id.
I don't have a controller, only one NodeMCU with NRF24 which is the "gateway" to Wifi - I use receive on the GateWay and upload the received data from nodes to POST on local MySQL server (I have a computer at home network with MySQL).
I need to track each node and know it's ID. Was that ID assigned automatically when I use AUTO mode?

And, do you have any suggestions on how to approach this?

The most important is that I want it to be seamless with IDs, I don't want to program each node of the 100 with static ID, cause if I make changes, it adds more complexity to update the system.

I found this:
#define AUTO 255 //!< ID 255 is reserved for auto initialization of nodeId.
#define BROADCAST_ADDRESS ((uint8_t)255) //!< broadcasts are addressed to ID 255
#define DISTANCE_INVALID ((uint8_t)255) //!< invalid distance when searching for parent
#define MAX_HOPS ((uint8_t)254) //!< maximal mumber of hops for ping/pong
#define INVALID_HOPS ((uint8_t)255) //!< invalid hops
#define MAX_SUBSEQ_MSGS 5 //!< Maximum number of subsequentially processed messages in FIFO (to prevent transport deadlock if HW issue)
#define CHKUPL_INTERVAL ((uint32_t)10000) //!< Minimum time interval to re-check uplink

in MyTrasport.h

I need to limit my radio system to nodes auto id up to 100.
which var should I change in order to set this?
tnx

Re: Using NRF24 - How can I limit the max auto NodeID number?

#define BROADCAST_ADDRESS ((uint8_t)255) //!< broadcasts are addressed to ID 255
#define DISTANCE_INVALID ((uint8_t)255) //!< invalid distance when searching for parent
#define MAX_HOPS ((uint8_t)254) //!< maximal mumber of hops for ping/pong
#define INVALID_HOPS ((uint8_t)255) //!< invalid hops
#define MAX_SUBSEQ_MSGS 5 //!< Maximum number of subsequentially processed messages in FIFO (to prevent transport deadlock if HW issue)
#define CHKUPL_INTERVAL ((uint32_t)10000) //!< Minimum time interval to re-check uplink

in MyTransport.h

now which one do I change to 100, so my radio system will be limited to nodes 0-100???

Tnx but this doesn't help much.
Setting up manually 100 nodes is not good for me.
I am sure that there is somewhere in the code of configuration, a var with the max node ID, because using NRF24 is limited to 254 nodes... so I need someone who knows around the code to help me out finding how to changes this number...
tnx.

Hi,
I would like to use Auto NodeID however I would like limit the max number of node ID to be 100 so that there is no change I will have a node with an ID greater than 100.
How can this be done?
tnx

Hi. I have an analog sensor that output voltage in a range of frequencies. I would like to creat a circuit to get the range of 0.5kHz to 1.2kHz and sendout const 5V if amplitude was over 3V.
This 5V I will connect to arduino digital input and send it as a tripped msg.
Any ideas?

how changing this will effect the communication of my sensor?

Hi. It doesnt work with mysensors 2.0 compling it. Any chance to covert it to be able to compile with 2.0 version?

Hi,
I use esp8266 wifi gateway with mysensors ver 2.0. I would like it also to recieve message from a sensor node (node 12) and do somthing like blink or switch a relay.
Ive tried to implement void recieve function (like i use in a node sensor) on the gateway and wait for sender to be node 12. But the gatway ignores the recive function and does nothing.
Any ideas?
Tnx

Hi, i am using UI7 and i am newto lua.
I know c.
I would like to have an intrevaled script that will put together an info text and send it to my lcdtext sensor.

1. How do i convert flot number to string and add a text together in lua?
2. I could not find a way to update the S_INFO device on vera using luup? Can u show me how?
   Tnx
