Did you get any log messages? Maybe try running nodejs /usr/local/bin/cgateweb/index.js directly and see if there are any errors?

[vworp]

No log created at /usr/local/bin/cgateweb/log
running node index.js:-
CONNECTED TO C-GATE COMMAND PORT: 127.0.0.1:20023
CONNECTED TO C-GATE EVENT PORT: 127.0.0.1:20025
CONNECTED TO MQTT: 127.0.0.1:1883
ALL CONNECTED
^C

Running index.js directly worked for a while. I was receiving MQTT messages into node-red and was able to respond and publish to C-gate. After a while (less than an hour, I got distracted) MQTT messages stopped.
I've rebooted the pi, verified that ser2sock, mosquitto, cgate services are running. cgateweb service still has the same error as before, still has no log file
Permissions are as follows.

Directly starting index.js now appears to have no affect
node index.js:-
CONNECTED TO C-GATE COMMAND PORT: 127.0.0.1:20023
CONNECTED TO C-GATE EVENT PORT: 127.0.0.1:20025
CONNECTED TO MQTT: 127.0.0.1:1883
ALL CONNECTED

then hangs with no command prompt or MQTT messages sent.

[the1laz]

That's weird. Maybe try changing this line in /etc/systemd/system/cgateweb.service

ExecStart=/usr/local/bin/cgateweb/index.js

Then sudo systemctl daemon-reload

The logs won't go to that folder anymore, journalctl should manage them, they should appear when you sudo service cgateweb status

Have you turned on logging in the settings file? Might give a bit more information.

In case, it helps, my cgateweb.service from my pi is below.

Note that

• this has not been updated as per the current release
• it was adjusted/written by me - and I am a long way from an expert on these things
• I put in the 5s delay to ensure that my Mosquito broker had a chance to start - a kludge

Sorry, forgot to add this:
sudo chmod +x /usr/local/bin/cgateweb/index.js

[the1laz]

Also, are you running raspbian?

[vworp]

Yes, on raspbian, installed from NOOBS a couple of weeks ago. apt-get update & upgrade after the installation, so should be up to date.

Done sudo chmod +x /usr/local/bin/cgateweb/index.js then sudo systemctl daemon-reload again, same problem.

I may have missed a chmod in the initial setup. I appear to have a running service and MQTT messages being relayed. I'll test for a couple of days, fingers crossed it's all my fault :)

[the1laz]

Good to hear, I wasn't really sure where to look next. :S

[vworp]

I'm all fixed, everything is starting and running ok across reboots. Would you be interested in a token financial gesture for your work? This is already pretty useful to me :)

[the1laz]

I've got an Amazon wishlist on my blog, but I'm not chasing anything for helping. I'm happy that my hobby can help other people with theirs. :)
