ordered some new Arduino boards, i will try to go exactly with the guides ...

not sure why i am getting empty payload, it seems that all is ok on the GW side

1. i am able to get MQTT msg when it connects
2. i am able to get MQTT msg from GW when i connect the sensor

the issue is that i am getting empty payload, and also different IDs for each msg

also I was not able to set a working controller as i have only MQTT gateway with NodeMCU
do you know if i can connect to OH? from docs it says you can only connect the serial and the ethernet

Hi i have the W5500 with pins and board
this one
and Arduino Uno R3
anything i need to change?

1. i guess i don't need that 3.3 converter right?
2. i did the change of \Ethernet\src flashed the board
3. now i will connect the NRF24 just like you did ? same pins?

anything else I should change?

it's late I will give this all a fresh try tomorrow, also i have IDE issues
not sure if related... I will start from fresh, Compile the gateway and sensor and will see

1. WARNING: Category 'Input' in library SerialSensors is not valid. Setting to 'Uncategorized'

2. Invalid version '1.04' for library in: C:\Users\gadof01\Documents\Arduino\libraries\UIPEthernet1

3. avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0x08

thanks for all the help!

i will give it a try ... Openhab is great!

so what you are saying i must have a controller in the system to have Nodes IDs assigned to my sensors?
i am trying to understand the flow here please elaborate

so i need to have a

1. working Openhab with binding (this will assign node id to the sensor )
2. working gateway (with only changes i have done above)
3. working sensor and not touch anything and the controller will do the work?

sorry, i am having a little trouble understanding the logic here?
thanks for your patience really

i don't see such def MY_NODE_ID 100 on the gateway sketch or the sensor
maybe i missed something here?

1. flash the gateway with ESP8266MQTTGateway.ino (only this?)
   do i need to change the sketch here?
   i put Wifi and MQTT

2. flash the sensor with some sketch (for example PIR)
   did not do any change

do i need to modify the sketches more?
do i have the right gateway sketch? or do i need to add somthing there

 * 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.

 *******************************
 *
 * REVISION HISTORY
 * Version 1.0 - Henrik Ekblad
 *
 * DESCRIPTION
 * The ESP8266 MQTT gateway sends radio network (or locally attached sensors) data to your MQTT broker.
 * The node also listens to MY_MQTT_TOPIC_PREFIX and sends out those messages to the radio network
 *
 * LED purposes:
 * - To use the feature, uncomment any of the MY_DEFAULT_xx_LED_PINs in your sketch
 * - RX (green) - blink fast on radio message received. In inclusion mode will blink fast only on presentation received
 * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
 * - ERR (red) - fast blink on error during transmission error or receive crc error
 *
 * See https://www.mysensors.org/build/connect_radio for wiring instructions.
 *
 * If you are using a "barebone" ESP8266, see
 * https://www.mysensors.org/build/esp8266_gateway#wiring-for-barebone-esp8266
 *
 * Inclusion mode button:
 * - Connect GPIO5 (=D1) via switch to GND ('inclusion switch')
 *
 * Hardware SHA204 signing is currently not supported!
 *
 * Make sure to fill in your ssid and WiFi password below for ssid & pass.

Thanks, i will try to change this #define MY_NODE_ID 100
on my gateway

i am using ESP12 NodeMCU 1.0 rev with nRF24L01 for gateway and sketch ESP + MQTT
for Sketch i am using ESP8266MQTTGateway

i am not using any controller , i planed to use MQTT to get the messages , is that ok?

i have openhab running on my Home but i was planning to use node red only for this

msg from one of the sensors

108525 TSM:ID
108525 TSM:ID:REQ
108529 TSF:MSG:SEND,255-255-0-0,s=237,c=3,t=3,pt=0,l=0,sg=0,ft=0,st=OK:
110538 !TSM:ID:FAIL
110540 TSM:FAIL:CNT=6
110542 TSM:FAIL:DIS
110544 TSF:TDI:TSL

looks like no good but, when I connect it the gateway responses like something is trying to connect or connected
also child ID is different so i am not able to understand

Hi I have the below setup

One NodeMCU with Gateway + MQTT

I think its working can anyone tell me, if all ok?
• I am able to receive MQTT from the gateway with the version number as payload
• I can see below logs and then gateway go to some kind of idle mode I think
• It looks like MQTT is ok but I see no indication for NRF is up and running…

I have many devices that I have tried to configure as senores, but not a lot of luck
Only good thing I can see that I am getting msgs from new nodes in MQTT (gateway)
But each msg comes with different chilled ID and at the end 3/0/3
Also, the msg payload is empty

can anyone tell me if my gateway is ok?
so I can move forward

Hi, Solved!

for some reason, # did not give me any result...

this is the topic = mygateway1-out/0/255/0/0/18

@bgunnarb said in MQTT GW issues with sending MQTT msg:

MQTT.fx also

Hi yes i have tried # , i can see all my MQTT status but not this one...
doing this with node red ... same as MQTT.fx, also tried MQTT lens seems that there is nothing sending to the broker

but as i can see in the serial output, it says connected, anyway? i can up the debug level to the MQTT connection?

strange thing is that the code does not say what broker it is connected to

35921 GWT:RMQ:MQTT CONNECTED
35951 GWT:TPS:TOPIC=mygateway1-out/0/255/0/0/18,MSG SENT```

i have set up a MQTT GW on ESP12 for the first time...
in the serial monitor, all looks cool, right?

1. i am still not testing any sensors
2. i have RF24 connected but still was not able to test it has i have no sensors yet
3. i just want MQTT working for now

i have tested with all MQTT software i can find ,still not able to get MQTT msg from this topic
mygateway1-out or any of the related above, how can i troubleshot MQTT?
