Another PIR sensor

DaVinki

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?

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.

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

@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

@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)

A small piece from the mm-out.log:

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.
