I've been able to get MySensors working with HomeGenie using the MQTT gateway. It doesn't have two-way communication or software-based pairing yet, but I'll work on those in the future.
@Eric-Buhring great to hear that you managed to get it working. I have used solution like this (arduino+eth. shield+rf24) for some time.
Now I have switched to esp8266+rf24(version with antenna) as a gateway, it is a cool (and smaller) solution
I think that:
It does overlap with MySensors for the wireless network. MQTT-SN assumes a network that provides a bi-directional data transfer service between any node and a particular one (a gateway). MySensors wireless network could provide data transfer but the message are really tailored to transport sensor and actuator values.
MQTT-SN for the gateway - controller interface is not needed MQTT is for that more than fine
That said I like the idea of MQTT-SN but for it a "transparent network" makes more sense.
Never mind figured it out.
There was a problem somewhere in that sketch. basically started from scratch again. merged the W5100 MQTT client gateway sketch and the relay sketch. then referred to here for serial MQTT syntax.
Hope anyone else thats struggling finds this info useful.
@evb Still haven't had a chance to look at your PR, sorry.
Yes, the database tends to grow I have about 80MB after a year of use. Just added a function to delete all messages older than, say, a year.
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?
