Another PIR sensor

[DaVinki]

Hi all,

At this moment I am using my MM as a wall decoration instead of a mirror, displaying images using MMM-wallpaper and various other modules. I Have connected a PIR sensor to my Pi, which works, but is currently disabled since I use Google Home to turn on/off the monitor.

What I was thinking of is using the PIR sensor to show modules like weather forecast, nstreinen module etc. I Reckon this uses the “USER PRESENCE” notification. However, all PIR modules I look at are build to power off the monitor completely.

Is anyone able to build a module for this, or maybe push me in the right direction?

Hi,

to me it sounds more like pages/profiles you are looking for.
My https://github.com/Tom-Hirschberger/MMM-GPIO-Notifications module is able to trigger notifications based on GPIO events.
In combination with https://github.com/tosti007/MMM-ProfileSwitcher and https://github.com/Tom-Hirschberger/MMM-ProfileControl you could toggle through the profiles with your PIR sensor.

@wishmaster270 Thanks for the reply. I Have been trying to get this to work, but some simple code breaks my config:

     {
           module: 'MMM-GPIO-Notifications',
            config: {
                '22': {
                gpio_state: 0,
                gpio_debounce: 10,
                delay: 1000,
                notifications: [
                  {
                  notification: 'USER_PRESENCE',
                  payload: true,
                  profiles: 'pageOneEveryone',
                         },
                ]
                }
                }
        },
    {
        module: 'MMM-ProfileSwitcher',
        config: {
            // See 'Configuration options' for more information.
        {
         module: 'MMM-Wallpaper',
         classes: 'pageOneEveryone',
        },
        } 
    },

When commenting out the " modules" config in ProfileSwitcher, my config.js works. Is there something I am missing, or should I first create configurations for every single module?

seems there are too many {}

Code directly taken from the module page https://github.com/tosti007/MMM-ProfileSwitcher. Seems to me you need the bracket for a per module assignment of the class.

Removing the brackets results in a black screen. Assigning the wallpaper module to IgnoredModules class doesn’t change that. Using square brackets [] also breaks the config.

I Checked for comma’s, opening and closing brackets, the usual suspects, but as far as I can see I didn’t miss any.

npm config:check is an incorrect command.

The black screen shows no errors. It states that the modules are hidden. Even the wallpaper module, which should be ignored.

MMM-Wallpaper is suspended. module.js:198:7
MMM-Wallpaper is hidden. MMM-ProfileSwitcher.js:113:25

yeh,

npm run config:check

i would disable each module one at a time til I found the one hiding everything

add
disabled: true,
after the module statement

{
module: name,
disabled: true,
position:
config: {
}
}

Yeah, the culprit is MMM-ProfileSwitcher. Somehow I can not get that config working.

MMM-ProfileSwitcher

Hi,
your configuration of MMM-ProfileSwitcher is wrong. In your case it will simply look like this:

{
    module: 'MMM-ProfileSwitcher',
    config: {
        // See 'Configuration options' for more information.
    } 
}

But you need to add the classes part to your MMM-Wallpaper module:

 {  
      module: 'MMM-Wallpaper',
      config: {
          ...
      }
      classes: 'pageOneEveryone',
}, 

So your config will look like this:

{
    module: 'MMM-ProfileSwitcher',
    config: {
        defaultClass: "pageOneEveryone",
        ignoreModules: ["moduleVisiableOnEveryPageOne", "moduleVisibleOnEveryPageTwo"]
    } 
},
{  
      module: 'MMM-Wallpaper',
      config: {
         //Add your wallpaper config here
      }
      classes: 'pageOneEveryone',
}, 
{
     module: 'MMM-ProfileControl',
     position: 'bottom_bar',
     config: {
        profiles: [
           ['pageOneEveryone'],
           ['pageTwoEveryone'],
        ],
     }
},
{
     module: 'MMM-GPIO-Notifications',
     config: {
         '22': {
             gpio_state: 1,
             gpio_debounce: 10,
             delay: 1000,
             notifications: [
                 {
                    notification: 'PROFILE_DECREMENT_HORIZONTAL',
                 },
             ]
        }
  }
},

The result will be two pages “pageOneEveryone” and “pageTwoEveryone”.
Every time your PIR triggers an “1” the GPIO Module will send an Notification to switch to the next page (and start again with “pageOneEveryone” if the end is reached).

You then can add “classes: ‘pageOneEveryone’,” to every module you want to be displayed an “pageOneEveryone” and “classes: ‘pageTwoEveryone’,” to every module you want to be displayed on “pageTwoEveryone”.

If you want to have modules displayed on every page you can add them to the ignore list of MMM-ProfileSwitcher.

@wishmaster270 Hi,

Almost there. :-) . I’ve got two pages, PIR sensor is working. I can see notifications switching from page one to page two. However, the sensor seems to bounce. I can see the “enter” notification for page two, and almost immediately see the “leave” notification for page two. Sometimes it indeed accidentally switches to page two though, so the mechanism itself is working.

I Have been playing around with the debounce and delay timers, with no success.

What I’m trying to accomplish is switch to page two when the PIR is triggered, and return to page one using a timer in ProfileSwitcher.

Current config for GPIO-Notifications:

     {
           module: 'MMM-GPIO-Notifications',
            config: {
          '22': {
          gpio_state: 1,
          gpio_debounce: 1000,
          delay: 1000 * 20,
          notifications: [
            {
                'notification': 'PROFILE_DECREMENT_HORIZONTAL',
                'profiles': 'pageOneEveryone',
                 },
                ]
                }
                }
        },

Doesn’t the “profiles” flag only trigger an action when that specific profile is active?

[wishmaster270]

Sorry, my mistake. Sure the profiles option in the GPIO config will cause the module to only fire the notification on pageOneEveryone.

What kind of PIR are you using, a HC-SR501? Maybe your jumper is set to pulse a signal as long as a object is in distance.

[wishmaster270]

Ps.: My modules write a lot of debug output to the log file. Maybe there is a hint in “~/.pm2/logs/MagicMirror-out.log”

[DaVinki]

@wishmaster270 I’m using one of the cheaper sensors from a Chinese store. Doesn’t even have jumpers on it. Seems to me that setting the debounce ridiculously high would solve the issue of it keeping firing.

Kind of at a lost here. Reading the PIN with a Python script gives a contiinue high, with an occasional low. However, setting the gpio_state to 0 doesn’t give any reaction. It also does not seem to react to changing the debounce or delay timers.

[wishmaster270]

Maybe the problem is not the GPIO. Did you find same useful information in the log. Is the GPIO module fireing that often?

If an delay is configured in the GPIO module any events within this time range will be ignored. It is a simple mechanism and does not depend on the sensor. I use it with three PIRs in my setup without any problems.

Edit: There should be some entry like “MMM-GPIO-Notifications: : Skipped notifcation…” in the log if the delay works and the sensor fires

[DaVinki]

@wishmaster270 The GPIO does indeed fire a lot. I’m sure it is a simple mechanism. I’m trying to figure out a way to “filter” the signals. Be it by a delay, a debounce or whatever… there should be a simple work-around, right? (Don’t take this personally please, my work as IT engineer let’s me think in solutions and workarounds)

[wishmaster270]

Sorry if it look liked i am taking the things personal that wasn’t my goal.
I want my modules to work and not to cause problems…

Could it be that you run two Browser (maybe build in and a second head) because the notifications get fired twice?

Edit: The delay seems to work. Because there are 20 seconds between the first time the gpio fires and the second time.

[DaVinki]

@wishmaster270 No, it didn’t look like you took it personal, I just didn’t want you to on forehand.
I Have indeed a second browser open on my laptop. Never thought of that being the issue… :-D

Let’s close that one, and fiddle around with the timers a bit. My laptop shut down during lunchtime, and then I indeed saw the second screen show up.
