Serial Gateway and MQTT Broker

[jkandasa]

@Frank-C But I can write simple library to run independently to convert serial gateway messages to MQTT type. If you want.

[Frank C]

@jkandasa That would be fantastic if you could ? I think it would be a great feature :)

[jkandasa]

@Frank-C Yes, I can. but you have to run it as separate service. I will create a separate project for this work. I am not going to include this on MyController project.

[Frank C]

@jkandasa As a seperate service is okay, it would be very helpful. Thank you

@jkandasa Perfect!

Maybe this is enough for your requirement:

@FotoFieber Thanks for the suggestion, I got that working. I have had to change MyController to read an MQTT gateway. Problem now is MyController can't read the MQTT format of this script. Any suggestions or tips ?
MyController does such a great job with handling MySensors' data, it would be a pity to loose that functionality.

@Frank-C
The script uses the serial protocol and should be compatible with the mysesnosrs mqtt-gateway. Are the pub/sub-topics set correct?

[Frank C]

@FotoFieber MyController is getting the MQTT msg, but doesn't like it's format, i've had continuous error msg like below:
2017-02-16 18:17:34,657 ERROR [Thread-4] [org.mycontroller.standalone.provider.mysensors.MySensorsProviderBridge:60] Unable to process this rawMessage:RawMessage(gatewayId=2, data=2;0;1;0;23;36, subData=mysensors/1/out/, isTxMessage=false, networkType=MY_SENSORS)

MyController is set up with the correct topic, as seen in above Topic:/mysensors/1/out/ (i've also tried without the ending /).

[FotoFieber]

2;0;1;0;23;36 Is a correct message according to the serial API. I don't know anything about your controller...sorry

Maybe the controller needs the ; translated to / in the topic?

Have you tried to switch pub/sub topic?

[jkandasa]

@Frank-C Current approach of MyController on MQTT see only payload on message. Other data(nodeId, sensorIds, etc) from topic. Kindly create a request on MyController issue page. I will address this. If we address this I am not going to create separate service to parse serial-to-real-mqtt service type.

[Frank C]

@jkandasa Thanks for the follow up. I can see MyController is modifying the serial message into a customized MQTT msg (as you have said).
MyController works great with the serial so it would be good to keep that as is, and if we had an independent service to publish to a separate MQTT broker would be very helpful?

[jkandasa]

@Frank-C cool, we will go with independent service.

[Frank C]

@jkandasa :thumbsup:

[talhatec]

@jkandasa has the independent service been created? I would really love to see this feature. Im using Home Assistant for overall home automation. But I want to manage MySensors with MyController due to the better features to handle MySensor Nodes.

[jkandasa]

@talhatec Still I am working on this feature. I will update you once it gets ready.

[jkandasa]

@talhatec Thank you for your patience
Finally the first version of serial2mqtt adapter available and released for public. Kindly report issues if you find any on issues page

[Diego Baravalle]

@jkandasa Thanks very very much!

Awesome work!

:clap: :clap: :clap:

[talhatec]

@jkandasa Thank you very much, will give it a go over the weekend.

@jkandasa The serial2MQTT adapter worked for a while, but then it started to fail. Looking at the logs, its not receiving the data from serial properly
