Help getting started with MQTT gateway
-
Ahhh right okay, well this is what i kept reading in 'MyConfig.h':
// Node id defaults to AUTO (tries to fetch id from controller) #ifndef MY_NODE_ID #define MY_NODE_ID AUTO #endifHowever, i shall manually set the ID on my nodes now.
I have put '#define MY_NODE_ID 42' into the humidity sketch, that isn't working, is there a specific place it needs to be? I'm just looking through the config files to see where about in the sendMessage code it calls for it and how it calls for it. I've tried to comment those lines out so it doesn't even attempt to get a ID from the controller, that isn't working at the moment.

I tried what you advised but it wasn't asigning a ID to the node still. So after a little looking around i found that you can specify the node id within gw.begin().
So i have got it as gw.begin(NULL, 4, false).
While i understand that the second piece of data is the node id, and the third is whether or not it goes into sleep mode. What is the first? Also, with me calling false for the sleep mode and then at the end of the sketch it tells the node to sleep for 30 seconds, am i over riding that sleep mode that i call at the end?
-
Ah.. you're running mixed library versions on node/gateway.. Yes, then you'd need to call gw.begin() on the node.
But will this overwrite any config/settings like sleep or anything? What does the NULL mean at the start of gw.begin?

I'm sorry, i got confused about which version i was running. I thought it was the development humidity sketch and therefor i didn't look for the API of it. Makes sense now. Thank you.

I now have my controller, broker and gateway setup working fine. I then created a temp and humidity sensor, works fine. I then made a motion node, works fine. Then a light switch node that all work perfectly fine together. Now, i come to configure my relay module (which im struggling with getting it to receive the messages) so i open my serial monitor for the gateway and see that even though its got a solid connection, it keeps trying to make another MQTT connection. Over and over again....

Just to let you know (Not sure if it tells you that i have edited a post), i have removed what i said about the gateway not working, that is back online now, however its back to doing exactly what it was doing earlier and keep trying to connect. But literally its spamming at a rate of like 10/20 per second...
0;0;3;0;9;Attempting MQTT connection... 0;0;3;0;9;MQTT connected 0;0;3;0;9;Attempting MQTT connection... 0;0;3;0;9;MQTT connectedI have a weird feeling that there may be a power issue or a connection issue somewhere on this gateway. (Its in a cupboard since i got it working this morning so its a little hard for me to believe it).
I have tried a restart on the MQTT broker btw, still nothing.

I now feel like a very big silly idiot. Let this be a lesson to anyone thats developing any sort of project. Document everything in some way, pen and paper or in a file.
I had refreshed the sketch and used the same clientID as the raspberrypi was using when i had my old automation server running there.
