AM312 Motion Sensor

[DSRocker]

I tried the AM312 Motion Sensor on different GPIOs. Configured / selected the GPIO as an Input-Pin in HASP. But nothing happens.
The Plate is integrated in Home Assistant; but the Sensor is not discoverd...
Do I have to pay attention to anything else?

[nagyrobi]

You need to write some custom C code to make it work that way, dude.

[DSRocker]

Oh ok. The same woth other devices like relay, LEDs,...?
Do you have an example for me how to do it?

[nagyrobi]

Not yet, this is wotk in progress

[DSRocker]

I would like to compile my own version, but it does not work with VSC. The compiling is sucsessful but the ESP blinking after flashing the bin and nothing happens...

[fvanroie]

What ESP32 and TFT are you using? And which environment did you compile the firmware for?
The hardware and firmware configurations need to match or it won't run properly...

[DSRocker]

ESP32 WROOM 32
I compiled D1mini for the esp32. Is it wrong?
And what about motion sensor ? Is it possible to use it?
Thanks a lot!!!

[fvanroie]

I compiled D1mini for the esp32. Is it wrong?

It depends on what ESP32 dev-board and TFT are you using... the compiled firmware configuration must match the hardware pins.

And what about motion sensor ? Is it possible to use it?

I think it should work by just connecting it to an input pin. Check the Pull-Up / Pull-Down resistor configuration.
Check in the openHASP or MQTT logs if movement is detected.

[DSRocker]

I use this board with the pin configuration like wirtten:
https://haswitchplate.github.io/openHASP-docs/latest/displays/MSPxxxx/

Which pin do you recommend to use for the motion sensor on the esp32 wroom?

[DSRocker]

motion sensor works fine on GPIO27. Thanks!

Hi'
I use an AM312 sensor with one of my wt32-sc01 plates to turn on backlight if presence is detected. Works perfectly !
I'm using pin 4, inverted and type presence.

Small "page":0,"id":8 plate config to indicate PIR (little green/red man) on the display in my top bar:

{"page":0,"obj":"roller","id":4,"enabled":false,"x":0,"y":0,"w":320,"h":45,"val":0,"rows":1,"options":"PAGE 1\nSONOS\nOFFICE\nPAGE 4\nPAGE 5","text_font":24,"bg_opa":100,"bg_color1":"#000000","text_color1":"#FFFFFF","bg_color":"#000000","text_color":"#000000","border_side":0,"radius":0}
{"page":0,"obj":"label","id":5,"enabled":false,"x":227,"y":5,"h":45,"w":90,"text":"\ue50f 00.0°C","align":2,"bg_color":"#2C3E50","text_color":"#FFFFFF","text_font":24}
{"page":0,"page":0,"id":6,"obj":"label","enabled":false,"x":3,"y":5,"h":45,"w":62,"text":"00:00","align":0,"bg_color":"#2C3E50","text_color":"#FFFFFF","text_font":24}
{"page":0,"id":7,"obj":"label","enabled":false,"x":60,"y":2,"w":30,"h":45,"text":"\uE5A9","bg_color":"#2C3E50","text_color":"#FFFFFF","text_font":16}
{"page":0,"id":8,"obj":"label","enabled":false,"x":75,"y":2,"w":30,"h":45,"text":"\ue004","bg_color":"#2C3E50","text_color":"green","text_font":16}

And two small automations to change glyph/colour on precense detection as well as wake up plate (turn off idle mode)
This could easily be done as custom component config as well.

- id: hasp_pir_on_display_wt32_02_mqtt
  alias: hasp_pir_on_display_wt32_02_mqtt
  mode: single
  trigger:
    platform: mqtt
    topic: hasp/wt32_02/state/input4
    payload: '{"state":"on"}'
  action:
  - service: mqtt.publish
    data:
      topic: hasp/wt32_02/command/idle
      payload: 'off'
  - service: mqtt.publish
    data:
      topic: hasp/wt32_02/command
      payload: 'jsonl {"page":0,"id":8,"text_color":"maroon","text":"\ue64a"}'
      
- id: hasp_pir_off_display_wt32_02_mqtt
  alias: hasp_pir_off_display_wt32_02_mqtt
  mode: single
  trigger:
    platform: mqtt
    topic: hasp/wt32_02/state/input4
    payload: '{"state":"off"}'
  action:
  - service: mqtt.publish
    data:
      topic: hasp/wt32_02/command
      payload: 'jsonl {"page":0,"id":8,"text_color":"green","text":"\ue004"}' 

That's it, I guess. Give it a shot ! 😉🙋‍♂️

My pin 4 reference should most likely have been more precisely defined.
I used GPIO4 - so reference is to the ESP GPIO pins
Also same reference used in the openHASP webinterface.

So for my clarity
In the pin out settings
Pin 4 = gpi0 4 ?

I'm new at openhasp and the pin assignments are not as clear as say a d1mini or esp32 using esphome or tasmota. Not much documentation on what gpi0s you can use with the sco1 plus.
The docs say gpi04 is for LCD reset.

The plus seems kind of easy to use gpi0 physically because they include header connection and wires. I cut the wires to jump ground and gpi0 0 for boot.

[htvekov]

Yes, I used GPIO4 - but on a wt32-sc01. Not the plus version !
You can use whatever (almost) free available GPIO pin in openHASP.

[htvekov]

And yes, in the openHASP webinterface (config, gpio settings) the pin reference is the ESP's GPIO pin

[stovedoctor]

I am using a plus so I will use a different GI0 that 4

[htvekov]

Yup, I did exactly that! Things work MUCH better now. in theory it should work on the plate device. In practice, not so much.

Ehh, did what exactly ? This thread is a bit complicated to navigate in 😆

[jazzmonger]

Interesting. I'm about to try this with a Panasonic PIR sensor. I bench tested the AM312 and it was really flakey. Sometimes it fired, sometimes it didn't. The Panasonic was rock solid. It requires a pull down resistor tho.

If you used a custom component, that would need to be compiled into a custom binary, correct? But if I understand correctly, that would keep it local and work without home assistant.

Did you do that? If so, can you share how to do it?

[htvekov]

I didn't use any custom component in my AM312 build.
As described above, the sensor is connected directly to pin 4 and tied to group 1.
This config relies on external communication with HA/node-RED to process the state change mqtt message and issue an idle off command.

I guess with latest changes in openHASP where button action events can execute commands, it's now possible to do all locally on the device. Just create a hidden, 'dummy' toggle button object that's connected to group 1 as well. And then execute the idle off command from that objects action. Not tested IRL, but it should work and will most likely also be a near instant action. My current mqtt setup takes some 0,5 seconds from detection to idle off command is executed.

Perhaps @fvanroie could at some point enhance the command executions to gpio states as well ? 🙂

I've looked all over and cant seem to find anything that indicates which GPIO pins are safe to use on the Lanbon L8 for my PID sensor. I got the Homekit version and I see a space for what on some other models is a Tuya Chip. might there be udable gpoi's on those pads?

Some free pins are available.
@bensuffolk identified some for his wired ethernet Lanbon project.

I'm looking for a reasonably priced larger screen and yours looks interesting. Are you happy w/ the wt32-sc01?
I see there are two versions of the wt32-sc01, a standard and "Plus". Which do you recommend?

[htvekov]

Hi' You should definitely go for the plus model. The IPS display has superior viewing angles compared to the TFT display on the initial non plus version. Also fitted with newest ESP32 version and 16MB flash. PSram only at 2 MB on the plus verison for some odd reason, but that's not really an issue.

Note: You'll need a 7 pin JST 1,25mm cable and a serial flashing tool in order to do the initial flash.

flash on the debug connector?

👍👍👍

[htvekov]

Yep. You'll need the initial openHASP flash via the debug connector to get the bootloader in place.
Afterwards you should be able to reflash using the USB interface. Haven't tested that though.
You could solder thin wires to the connector, but I wouldn't recommend it. That pitch size is really not that funny soldering by hand 😉

[htvekov]

Hmm.... That picture above is not the sc-01 plus model but the 'old' original wt32-sc01

[jazzmonger]

It says PLUS in the description - it was the link you gave me. probably just a stock photo in the orders screen
So I think I'm good.

[pauldogg]

Can someone please post the proper setup for the AM312 Motion Sensor please?

Motion?
Presence?
Group?
Pullup?
Pulldown?
Inverted?
normal?

Thanks

[htvekov]

Look at my post further up from February, 2022. My complete config is there. Only thing missing is the pullup/pulldown setting. Can't remember the setting on the spur of the moment 🙂

[htvekov]

Default state should be: Normally closed (inverted)
And Resistor set to: Internal pullup

[pauldogg]

Thank you!

[jazzmonger]

I'm curious if anyone has done this locally yet and compiled the firmware? If so care to share?
