💬 Building a Raspberry Pi Gateway

MasMat

I need help with my Rpi mqtt-gw.
I tried to get dev-branch working but changed now to stable. All the install routines run without problems. The service just doesn't seem to work and I can't figure out why.

Rpi W, Raspbian wheezy, nRF24-PA, MQTT-gw, Mosquitto and Openhab2 on same board
Mosquitto-log:

1521010232: New connection from 127.0.0.1 on port 1883.
1521010232: New client connected from 127.0.0.1 as mygateway1 (c1, k15, u'xxxx').
1521010232: Socket error on client mygateway1, disconnecting.

syslog:

GW configure-line:

./configure --my-transport=nrf24 --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-rf24-irq-pin=15 --my-leds-err-pin=12 --my-leds-rx-pin=16 --my-leds-tx-pin=18 --my-mqtt-user=xxxx --my-mqtt-password=yyyyy --my-signing=password --my-signing-password=zzzzzz```

I have checked mosquitto has correct user-pw combination, but what should I check next? Help!

@masmat said in 💬 Building a Raspberry Pi Gateway:

--my-mqtt-client-id=mygateway1

Do you have another client named mygateway1 connecting to mqtt? Try changing it to a different name just to play safe

MasMat

@gohan Can I just edit mysgw.cpp and do "daemon-reload"?
I have just this one gw. And openHab2 but that has a different id.

gohan

No, you need to recompile it again in case you make that change. Have you ever tried dietpi for RPI?

MasMat

@gohan OK. I did that, the same socket error remains in Mosquitto just under new id.
Is my syntax correct or am I somehow having problems with mosquitto user-pw...?

Haven't tried DietPi. Would Mys+Mosquitto+Openhab2 have trouble running on it? Or why should I change to it?

gohan

have you tried connecting with another mqtt client like mqttfx to see if everything is working?

marceloaqno

@masmat What is the mqtt broker / version you are using?

marceloaqno

@gieljnssns One way is to replace the changed files, in this case EthernetServer.cpp for the first patch and EthernetClient.cpp for the second patch.

You can download from:
https://raw.githubusercontent.com/marceloaqno/MySensors/linux-fix-stability/drivers/Linux/EthernetServer.cpp
https://raw.githubusercontent.com/marceloaqno/MySensors/linux-fix-stability/drivers/Linux/EthernetClient.cpp

Here is a step-by-step:

git clone https://github.com/mysensors/MySensors.git
cd MySensors
curl https://raw.githubusercontent.com/marceloaqno/MySensors/linux-fix-stability/drivers/Linux/EthernetServer.cpp -o drivers/Linux/EthernetServer.cpp
curl https://raw.githubusercontent.com/marceloaqno/MySensors/linux-fix-stability/drivers/Linux/EthernetClient.cpp -o drivers/Linux/EthernetClient.cpp

from here just run ./configure with your options and then make

MasMat

@marceloaqno Mosquitto v1.4.14.
The broker is working, at least sending & receiving command line (_sub & _pub) messages.

? Offline

@gohan

Can you provide some installation instructions for dietpi?
I will try this...

gohan

just download the image and do the same as a Raspian image. I haven't tried mqtt gateway yet, so I don't know if it may be a gateway bug or else.

@marceloaqno :
Hi, unfortunately the latest patch did not work for me.
Still the gw stops receiving, but without high cpu usage :-(
Fortunately I can restart the gw now using a button and this udp-scripts :-)

Of cource I could give dietpi a try, but I would think, that a general solution would be better (for other users as well)

cheers,
Otto

MasMat

@gohan I had another sd card and tried a ready image of DietPi with Mosquitto pre-installed.
I tried it without user/password and mosquitto accepting anonymous but:

/var/log/mosquitto/mosquitto.log:
1521141160: Socket error on client <unknown>, disconnecting.
1521141160: New connection from 127.0.0.1 on port 1883.
..keeps repeating...

...and sudo ./bin/mysgw -d:

mysgw: Starting gateway...

mysgw: MCO:BGN:INIT GW,CP=RNNGLSQX,VER=2.2.0

mvader

1st patch is still working good for me. have had no issues since applying it.

question. is it normal/correct for the gateway to ping or spam? every 10 seconds i see the gateway announce it's version.
its not doing the full restart or anything.. just giving the 2.2.0 every 10 seconds.

gohan

@masmat have you tried with ethernet gateway? If I have time I'll try the mqtt this weekend

@mvader I never noticed that.... is it the mqtt GW?

MasMat

@gohan How would I interface the rest of my HA without MQTT...that's at the center of my plan really :(

gohan

I think OH should support it, but I was just asking to make a test.

MasMat

@gohan I configured:
./configure --my-transport=nrf24 --my-gateway=ethernet --my-controller-ip-address=127.0.0.1 --my-rf24-irq-pin=15 --my-leds-err-pin=12 --my-leds-rx-pin=16 --my-leds-tx-pin=18 --my-signing=password --my-signing-password=ZZZZZZ

./bin/mysgw -d:

mysgw: Starting gateway...
mysgw: Protocol version - 2.2.0
mysgw: MCO:BGN:INIT GW,CP=RNNGLSQX,VER=2.2.0
mysgw: TSF:LRT:OK

mysgw: TSF:WUR:MS=0
mysgw: TSM:INIT:TSP OK
mysgw: TSM:INIT:GW MODE
mysgw: TSM:READY:ID=0,PAR=0,DIS=0
mysgw: MCO:REG:NOT NEEDED
mysgw: connect: Connection refused

mysgw: connect: Connection refused
mysgw: failed to connect
mysgw: GWT:TPS:ETH OK
mysgw: connect: Connection refused

The controller doesn't exist on the DietPi card yet but I'm not sure if that's causing the problem.

@masmat said in 💬 Building a Raspberry Pi Gateway:

--my-controller-ip-address=127.0.0.1

remove that parameter as it is not needed for ethernet

marceloaqno

@masmat I did a test with the following configuration:

Raspberry Pi 1 with Raspbian (2017-11-29-raspbian-stretch-lite)

pi@raspberrypi:~/MySensors $ lsb_release -a
No LSB modules are available.
Distributor ID: Raspbian

./configure --my-transport=nrf24 --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=m ygateway1 --my-mqtt-user=rpi --my-mqtt-password=password

Mosquitto version 1.4.10 (build date Fri, 22 Dec 2017 08:19:25 +0000) [installed from apt-get]

pi@raspberrypi:~/MySensors $ cat /etc/mosquitto/mosquitto.conf

Added the mosquitto user (user=rpi, password=password) with:

sudo mosquitto_passwd -c /etc/mosquitto/passwordfile rpi

It didn't show any error to connect to the MQTT broker:
