💬 Building a Raspberry Pi Gateway

@gohan :
dietpi looks interesting! did not know about this yet.
what hardware are you using? and what version of mysgw?

[otto001]

@marceloaqno :
THANKS! Just applied your patch.
I will report in a few days when I can see if the problem is solved...
Cheers,
Otto

Can someone tell me how to apply this patch?

[gohan]

@otto001 normal rpi3 and mysgw 2.2

[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.

1. 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:

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.

@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.

[otto001]

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

mysgw: TSM:INIT:TSP OK

mysgw: MCO:REG:NOT NEEDED

[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 :(
