MMM-Pir toggling

ttt126

Thank you very much, I spent the whole day trying to understand notification triggers and producing a config, unfortunately without success.
Maybe you can help me out. how do I do the config so that the trigger can be taken over by mmmpir? I’ve already created a small py script with a gpio pin that goes on and off, it’s in the root directory.
But I just can’t get the execut function to be implemented.

{
module: “MMM-NotificationTrigger”,
config: {
triggers:[
{
trigger: “USER_PRESENCE”,
fires: [
{
exec: “/neu1.py”
}
],
},
]
}
},

@ttt126 said in MMM-Pir toggling:

exec: “/neu1.py”

that means in the root system folder’if you meant YOUR home folder
that would be , replace username with really logged on user for home folder

/home/username/neu1.py

there may have been messages posted to the MM startup output

ttt126

Even with /home/pi/neu1.py it is not responding.
Do I have to devine true and fals state in the config as well?

sdetweil

@ttt126 can you execute the script manually from the terminal window?

ttt126

Yes, this I can.

@ttt126 ok, i was checking for permissions

did you check the messages from npm start location, see if any errors were posted

@ttt126 that means you started MM AGAIN…

if you are using PM2, then you need to use the pm2 commands

pm2 status
pm2 stop x
where x is the name or number of the row of the app you want control
and then pm2 start x

or you can do

pm2 restart x

I STRONGLY recommend using manual start while you are developing your mm solution
changing config, adding modules

pm2 stop all

cd ~/MagicMirror
npm start

to stop MM in this mode, hit ctrl-q on the MM screen

if you do this over ssh cause you have no keyboard on the mm system (like me all the time) press ctrl-c in the ssh window where you did npm start

(if you do this when PM2 is controlling, it will do its job, “keep the app running”,
you stop it, and pm2 will restart it… )

ttt126

so this is the aktual config
the command python3 /home/pi/neu1.py is acting the relay if executed in termnal
I use fire and exec both with no action.
maybe there is no trigger natification.

module: "MMM-NotificationTrigger",
                       config: {
                         triggers:[
                           {
                              trigger: "USER_PRESENCE",
                              fires: [
                                {
                                  fire:"python3 /home/pi/neu1.py",
                                  exec: (payload) => {
                                    return "python3 /homr/pi/neu1.py " + payload.option
                                  }
                                },
                               ],
                             },
                           ]
                         }

ttt126

I got it working, many thanks for your Help :-)

sdetweil

@ttt126 what was the issue? might help others in the same predicament

ttt126

@ttt126 said in MMM-Pir toggling:

config: {
triggers:[
{
trigger: “USER_PRESENCE”,
fires: [
{
exec: (payload) => {
return "python3 /homr/pi/neu1.py " + payload.option
}
},
],
},
]
}

The pathon3 comand was missing. I´m not quite firm with programming.
But a serce for executing a py script brought the answere!

sdetweil

@ttt126 ok… two things…

when posting config or logs info in the forum, please use the code-block wrapper

to use

paste the text you want to post, blank line above and below
select the text you just pasted
hit the </> button above the editor to add the wrapper

on linux, you can specify the program to launch to execute a ‘script/program’
you do this by adding a special first line

#!/path_to_executable/programname

so in your case
from a terminal window do

which python3

the which pgm returns the full path to the 1st instance of the program specified as located along the path . on my desktop that is

which python3
/home/sam/anaconda3/bin/python3

then in you editor of your script, make this the 1st line

#!path_from_which

so it looks like this

#!/home/sam/anaconda3/bin/python3

the linux execution code does all this stuff under the covers, reads the 1st line and invokes that pgm with the arguments passed to the script
and of course, if no #! then the script USER has to specify it like you did
