💬 Building a Raspberry Pi Gateway

[marceloaqno]

@Reza You could connect the rs485 to the RPi UART and use the option --my-rs485-serial-port=/dev/ttyAMA0, but you need to turning off the UART functioning as a serial console.

Or, to make things easier:
rs485 <==> TTL/USB <==> RPi

@marceloaqno
i am beginner and i can not turning off the UART functioning. . . also on some board usb port after power off/on lost and i should disconnect/connect cable... i test your steps serial gateway with raspberry and GPIO with virtual usb serial . and i see this problem solve and after power off/on gateway is connect .
i suggest that you add this commands to page of rs485 gateway step by step and update this .
(https://www.mysensors.org/build/rs485)

I thank you for hard working and trying

@Reza

if you want use rpi /dev/ttyAMA0 for rs485 gateway -

1. remove string "console=serial0,115200" from /boot/cmdline.txt
2. add strings "enable_uart=1" and "dtoverlay=pi3-disable-bt" to /boot/config.txt (only on rpi3)
3. reboot raspi

@marceloaqno nice, working now :+1:

Thank you...

[Reza]

@b0rmann
thank you friend , but i am sorry i am very beginner in raspberry pi . because i use vera before and with raspberry and orange pi i use recently. so i need a full steps for a rs485 gateway(wiring and commands . . .) i dont know what is ttyAMA0 ! i use a serial gateway with usb port with raspberrypi 3 but i have some problem , but with a raspberrypi gateway and use a virtual serial port (ttyUSB020) all of my problem resolve. but i have problem with wireless. so i want have a wiring network. i want a full steps for setup a rs485 module with raspberrypi 3(wiring and steps for install...) thank you for help

[Anduril]

Do I read that correctly, does this gateway also gives a ethernet link to a serial-only controller? How do I have to configure ip and port? In the build section I see no option to set them.

@ericvdb

Okay what could be the problem? :3

[marceloaqno]

@Reza There are many guides on the web teaching how to connect and use rs485 with the RPi. I recommend you start with them and when you are sure it is working, you add MySensors to the equation.

ok thank you :(

@Anduril
you will get all the build options for the mysgw with the command

./configure -help

Here you can configure all options like serial and ethernet

[Anduril]

just cloned and read the --help, but still I don't know how to use.
To make it a litte less abstract: I have a ethernet gateway (ESP8266) running at 192.168.38.19 with port 5003 to connect to. I want to have this accessible by a serial-only controller on the raspberry.

I tried to do this config and make afterwards, but starting gave only FAILs...

./configure --my-gateway=ethernet --my-controller-ip-address=192.168.38.19 --my-serial-is-pty --my-serial-pty=/dev/ttyMySensorsGateway

~/MySensors$ sudo ./bin/mysgw -d

I think my config is wrong and it tries to connect to a nrf24 at the rpi. So what's the correct config for my case?

Thanks in advance.

@Anduril
Why are you using an esp8266 as a serial gateway? Wouldn't it be easier to use a normal UNO?

[Anduril]

I'm using a ESP8266 as ethernet gateway and want to have this connected as virtuall serial port to my raspberry pi so my controller can connect to that.

[lakshmc]

I using RPi2 and NRF24 for this. I followed the instructions, to clone the repo, and then added config
./configure --my-gateway=mqtt --my-controller-ip-address=127.0.0.1 --my-mqtt-publish-topic-prefix=mysensors-out --my-mqtt-subscribe-topic-prefix=mysensors-in --my-mqtt-client-id=mygateway1 --my-transport=nrf24

make

when i run with sudo ./bin/mysgw -d, it is failing to connect to MQTT. Can you please help?

@Anduril

Have you aver considered Using the GatewayESP8266MQTTClient? What controller are you trying to connect?

[Anduril]

I use pimatic which does not have a native compatibility to ethernet or mqtt. Thats why my question came up on how to configure it to do this...

Building a Raspberry Pi Gateway:

If you are running a controller on the Raspberry Pi that doesn't support communication with the gateway through ethernet, you can use a virtual serial port:
./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyMySensorsGateway

[mfalkvidd]

@Anduril you might be able to use nodered or socat to convert the tcp connection to a serial port.
https://linux.die.net/man/1/socat
https://nodered.org/

[Anduril]

that's what I tried in the past and am using now (socat), but it does not reconnect and has some other drawbacks. Reading of an officially supported way sounded interesting

[pete1450]

@lakshmc Make sure you don't have the daemon running already

If not, I'm getting the same problem on the 2.1.1 that was just released. 2.1.0 was working "fine"(besides my suspecting a bug that doesn't let any inclusion happen, hence I tried the new version). Time to go back to the serial gateway right into the vera.

[marceloaqno]

@pete1450 @lakshmc
Make sure you are not using an old version of mosquitto (or any other broker you're using):

$ mosquitto -h
mosquitto version 1.4.10 (build date 2016-09-20 11:02:07-0600)

It's working fine with the 2.1.1 release:
