myscontroller with ethernet gateway

JohnDoe2991

Hi everyone!

I currently try to setup my first MySensors network.
I have a sensor and an ethernet gateway sitting on a breadboard and I try to get the sensor data into my database with NodeRed.
NodeRed is running in a docker container on my database server.
But I am not able to get the NodeRed myscontroller to work.
Here is my test flow:

        "file": "/data/mysensorsnode.db"
    }
]

For me it looks like the controller receives messages from the gateway and response to them within the flow but the messages don't go to back to the gateway.

I tested my setup with the MyController controller just to be sure my hardware works and everything worked instantly.

I'm not very familiar with NodeRed so I guess I made some mistake. Can someone point me to the right direction?

I'm wondering if you have to decode before going to myscontroller

So like this

Thanks for the reply, I think I've figured it out now:
If i connect the myscontroller directly with the TCP connections, it won't send any messages. More importantly it looks like the whole gateway stops working correctly then. I don't receive any messages from the TCP connection.
I have to add an decode and encode on each side of the myscontroller and restart the gateway so it will work properly.

I guess when I tried my first flow yesterday I connected the myscontroller directly to the TCP connections and crashed my gateway this way. I didn't noticed that and thats why my second flow with the decode and encode didn't work either.

So, all in all, it was just a "Have you tried turning it off and on again?" problem.

electrik

Good to hear you solved it!

JohnDoe2991

Well, I'm back again, because it broke again ... and I fixed it somehow again.
I was playing around with my sensor to get it up and running the way I want it to and resetted its node id.
It couldn't get a new node ID and I was back where I was yesterday.
Deleted everything, rebuild the complete flow, restarted everything. Nothing helped. So I added debug messages everywhere and also had a look into the raw Serial protocol here: https://www.mysensors.org/download/serial_api_20
It looks like you don't need the encode and decode, at least for me the encode after myscontroller totally destroyed the payload. Why did it work yesterday? I have no idea.
The payload looked fine now without the decode and encode according to the protocol, but it still didn't work. I noticed that the incoming TCP payload always ended with a linefeed "\n", so I added a custom function between the myscontroller and tcp output to also add a linefeed to the outgoing payload and it's working again.
