Creating in domoticz light switch to use with MQTT

[Posiek]

Hi,
I'm trying to create light switch which will use mosquitto_pub with my custom subject and message, but I can't find this option. Maybe someone use that before? I want to send command to my sonoff with custom firmware.

Thanks in advance.

You can create a "dummy switch" and use the On/Off action to run the mosquitto_pub command (in a script)

Thanks for your answer. I tried something like this, but It doesn't work:

Code: Select all

script:///home/pi/domoticz/scripts/bash/script_sh070_off.sh

I tested this script in Putty and works fine. What I'am doing wrong?

EDIT:
I checked logs and found this:


Any ideas? I checked chmod, path etc.

What domoticz version are you running?
And how does the script look like?
Have you tried: script://home/pi/domoticz/scripts/bash/script_sh070_off.sh (only 2 x /)

My Domoticz version is 3.5877. Bash script have default bash header and 1 line with mosquitto_pub -t "/my/subject/" -m "message" and using SSH it works fine, my light switch off. Yup I tried many of path combination. Path checked tew times.

Bash script have default bash header

Can you change this to: #!/bin/sh

I changed that, but still doesn't work. But I don't have error in my logs:

Code: Select all

Now you do not have any errors, can you subscribe to the same topic now to see if the command is executed by domoticz?

I'm not sure that is proper way - nothing happen in SSH window (clicked few times):


and below test with second PuTTy window and the same command

Code: Select all

mosquitto_pub -t "......." -m "......."

:


It is strange that there is no error, and nothing is going on.

Well I use this all the time and works fine. I only run the latest Beta instead of latest stable like you do.

Maybe I should try to install on Windows Beta version and test it, but what about command? I guess I have to install mqtt for windows...

EDIT
My Broker on RPi should be universal for all devices -_-

It should work under Raspberry Linux just perfect. i run Domoticz on Ubuntu Linux without any problems. My advise, stay on Raspberry

Ok, maybe I can update to Beta version?

EDIT:
I update to latest beta, still nothing going on

[SweetPants]

yes, i would try. Just run the ./updatebeta script from the domoticz directory. But pleas make a backup of your database first

Of course backup is the basis. Domoticz updated and version now is 3.7320 but still nothing... I'm sure the problem is a tiny mistake

After update my log show something like that:

Code: Select all

2017-04-14 20:03:37.381 Error: SQLHelper: Error script not found '/home/pi/domoticz/scripts/home/pi/domoticz/scripts/script_sh070_on.sh'
2017-04-14 20:04:08.278 Error: SQLHelper: Error script not found '/home/pi/domoticz/scripts/home/pi/domoticz/scripts/script_sh070_on.sh'

so I changed path and now it looks like:

Code: Select all

2017-04-14 20:04:41.390 Error: Error executing script command (/home/pi/domoticz/scripts/script_sh070_off.sh). returned: 32512
2017-04-14 20:04:44.003 Error: Error executing script command (/home/pi/domoticz/scripts/script_sh070_on.sh). returned: 32512

My script have only 2 lines:

Code: Select all

#!/bin/sh
sudo mosquitto_pub -t "/sonoff/sh070/cmd" -m "OFF"

i tried with use sudo and without sudo

[SweetPants]

i'm out of options to try. My script looks like:

#!/bin/sh

TOPIC=/Device/$1/in;
MESSAGE={\"switch\":\"$2\"};

mosquitto_pub -h localhost -p 1884 -q 2 -r -u <username> -P <password> -t $TOPIC -m $MESSAGE

PS: I use authentication and a different port on my broker, but that should not make any difference

Yeah, auth doesn't matter. Basically script is similar :/

[Posiek]

FINALLY!

SweetPants thank you so much for your support and I should apologize for stupid mistake, becouse I found it. Solution as I said few post ago was simple - I make my bash script in Windows environment and it have DOS format. After copy to Linux it doesn't work properly. Now I write this again on RPi and give proper chmod and everything looks fine.

Thanks a lot. I hope someone finds something useful for themselves
