@Yveaux said in serial, Ethernet to MQTT:
Of course, but MySensors MQTT gateway runs just as fine when connected over cabled ethernet, as when connected over wifi
I do not know that
Now on this tool, I do not see much benefit from ethernet to MQTT
Still, it is good from serial to MQTT.
Thanks again, learned a lot... I decide to give a try there, I also had a look on some components' datasheet and seems to be what I need... Let's see, if end up getting the boards I'll publish a review here later.
Hi @GertSanders,
Do you happen to still have the Eagle project files from version 3 you created and shared on OSH Park? I'd like to add a set of pads for the mini smd version of the NRF24L01. If not, I'll just use the version 2 files from openhardware.io and try my best to recreate the changes you made between them.
Kind regards,
AH
Thanks for your fast reply.
That sounds easy.
And you think that the communication between sensor nodes and Gateway are still possible via wired RS485?
I tried to find an example on this site for sending Information from Gateway to sensor nodes. (via SendMessage ?)
For example I like to Switch on/off an light that is connected to an relay board at my sensor node.
Communcation Flow:
OpenHab2 --> MQTT --> Gateway --> RS485 --> Sensor Node --> Relay Board
Currently I have an working RS485 Connection between my Arduino Uno's with the use from SoftwareSerial library.
During my testings I realized, that the message that I triy to send "Hello" will be sent to the other arduino char by char. Is that true?
Because I tried to raise up an pin on HIGH with "if(msg == "Hello")..." But it doesn't worked.
Will the sendMsg method from the MySensor library handle this out of the box?
Regards,
Simon

Yes I think you need 1.4.1 or latest. The messages you see (0;0;3;9...) are traffic in the wireless sensor network.
My problem appeared again. The EthernetGateway responds to Ping but Vera plugin says:
"Cannot send command - communications error"
So perhaps increasing power could help, but how? Is adding capacitors enough?? Like for the radio there already is one..
