Hi Huys, I am trying to follow this guide however I have trouble finding some of the folders after the install.

In Step 5: The path ~/MagicMirror/modules/MMM-Hotword/node_modules/snowboy does not exist. I found Snowboy in ~/MagicMirror/modules/MMM-Hotword/snowboy instead.

In Step 5 after installing the assistant, I cannot find the folder scripts in ~/MagicMirror/modules/MMM-AssistantMk2 to make them executable.

Does anyone have an idea why that could be? I am running the latest Rasbian Buster distribution.

I found a solution for my monitor SAMSUNG S24F354 using:

DISPLAY=:0 xset dpms force on

DISPLAY=:0 xset dpms force off

This seems to work right now from the shell. Turns the monitor instantly off/on. Last night when trying with the PIR script, it didn’t work however, returning an error when calling shell scripts: the server was lacking dpms. This must be because DPMS was turned off as a part of the MagicMirror configuration.

I have a fresh install right now and just verified that these commands actually works. Now to get the PIR sensor working with the shell scripts.

Hi,
I know I am going to be flamed for asking this, but here goes…

I am trying to implement a PIR sensor on a Raspi 4b to turn on the HDMI output when activated. I have read page up and down of this issue and have seen different possible solutions, but nothing that works for me.

I can use tvservice -o to turn off HDMI just fine. When I use tvservice -p again, the monitor turns on, but remains only with backlight.

I have read something about adding a resistor on the powercable for the monitor, but have anyone found a solution to this? Is it because I am using a specific monitor or is this a general problem?

Best regards
Lars

@Fozi Thanks man. I will look into the foil + microwave sensor. For movement detection a very narrow angle could be used, just in front of the mirror.

Regarding the microphone, how did you solve that?

@MilkShake Actually, I do not think that the ToF will work from behind a mirror, so I might have to go with the PIR.

Hi,
I am contemplating building a mirror with Google Assistant, but would like to get some input on the selected hardware. I do not like PIR as the sensor would be sitting in the frame and it would not look good imo.

I have a RPI4 for the job.

I have a small USB mic. I am hoping that it will be able to pick up voice, even though it is sitting behind the mirror.

I will play audio through a bluetooth speaker. Is this stable or should I use a small jack speaker instead?

For motion detection I bought the ToF unit VL53L1X. That should work from inside the mirror and thus nothing will be visible on the outside. Has anyone used this before for motion detection?

Really hoping for some input.

Best Regards
