It will be good if you can use the RPI GPIO to connect directly to NRF24 RF module instead on adding the serial gateway ( see http://iot-playground.com ..)

Yes, I have plan to implement NRF24l01 directly. I have to learn more about how mysensors gateway is working. Also planing to implement RPI GPIO port access from MyController.org directly

I wish you good luck with this project.

Thank you! @davidbd

Actually, you can add the NRF24 directly to the Raspberry and use it as a gateway at the same time:

Thank you @GertSanders let me have a look. As MyController.org is designed with pure Java language I have to implement with some wrapper or with the help of pi4j module

@jkandasa
I used the Raspberry version of Mysensors gateway for software to set up a serial gateway. Then Inadded a symlink link with shorter name so domoticz could see it. If your software can detect the normal ttyMySensorGateway then no need for a symlink.
Hardware toconnect radio and raspberry is simple interconnect with GPIO. Same connections as with wire. I made a little board for it. Link to that is also somewhere on the forum.

@GertSanders This is nice, I guess no need to change anything in MyController software. Let me check this and update you. Thank you.

@GertSanders @davidbd Just now I tested https://github.com/mysensors/Raspberry with MyController.org server it is working perfectly. Thank you very much! you guys saved hardware cost and added direct NRF24 support to MyController.org :smiley:

I did all the steps as root user (running MyController.org server also as a root user). Kindly let me know if you face any issues.

Install https://github.com/mysensors/Raspberry and connect NRF24L01+ as mentioned on the page.

Now we have to point-out ttyMySensorsGateway port to MyController.org server via it is configuration file

Stop your MyController server change a line,
File Name: mycontroller/conf/mycontroller.properties

mcc.serialport.name=/dev/ttyMySensorsGateway

Start your MyController server. That is it :)

@jkandasa Well Done ! Thanks ! you are doing great Job here.

Hi,

I just install the PiGatewaySerial in RPI and run as a daemon but found CPU is almost 100% !

@davidbd I donot face any issue like you said.

I do not have much knowledge on PiGatewaySerial we have a discussion about this topic on http://forum.mysensors.org/topic/1151/tutorial-raspberry-pi-nrf24l01-direct-connection/39

Some people already reported 100% cpu usage. Can you please check and post your query there?

My RPI setup.

The 100% cpu usage happens only if nothing connects to /dev/ttyMySensorsGateway, at least thats what i experienced.

GertSanders

My CPU load hardly ever goes over 1%, and that is including a running Domoticz controller in parallel with the serial gateway.

@jkandasa As reported by users ... the 100% cpu usage happens only if nothing connects to /dev/ttyMySensorsGateway
I am OK now but maybe worth to check why as this is not good behaviour.

Just finished setting up MyController, so it runs besides domoticz, and NodeRed. Looks fine so far, but haven't had that much time to delve into MyController specifics yet.

Have set it up so that when ever I turn a light on / off in MyController, Domoticz also sees this (and of course the sensor network).

Plan was to try and use MyController for OTA firmware updates, and keep track of firmware versions in my network.

For some reason cannot seem to get it running.

Have installed the software and the server appears to start, but there is no web access and this is what I get when I check the log.

Have I setup something incorrect

You should update your java version to 1.8 or later. For raspberry PI oracle java is recommended for MyController.

@diggs hope this link will help you to update your java: http://www.rpiblog.com/2014/03/installing-oracle-jdk-8-on-raspberry-pi.html

@tbowmo Nice! you can give try for other features also which is available in MyController ;)
Alarm, Timer, Forward Payload, UID, etc.,

diggs

@jkandasa Thanks for that.

The latest Java version has go me going as far as server access goes, but I am having issues opening the serial port it seems.

I am trying to run in parallel with Domoticz, but I maybe having an issue trying to access the same port I am guess.

Suggestions on how to get around that?

I guess you cannot share same port for two different applications. We may go with some third party tools to share serial port across applications. But, I do not have any experience on it.

In this case to run MyController server, stop MyController server and Domoticz controller, then start MyController server, it will work.
