Transcripts

we've all been there doing your deed

watching your favorite YouTube videos

yeah then the lights go out

because you're sitting too damn still

so we're going to show you how to fix

this with your own inexpensive DIY ESP

home sensor to move the rugs so you

don't bust your butt on the floor okay

and you're trying to come back and forth

now run back and forth try to run in and

run out

go fast

you did it anyway

[Music]

okay try to do it without falling as

much

run when I come back

it still gets you huh

pretty damn quick for mm wave no

additional PIR sensor needed and it's a

freaking 10 damn sensor well then you

gotta add the ESP but that's not

expensive at all

pretty awesome and you can see my sexy

legs I haven't been this excited about a

damn sensor quite some time especially a

ten dollar sense or two and you can

build it yourself and then say I built

that so for part two of the

awkwardness of this video laying in the

tub here yes I am fully clothed so no

need to report the video we wear clothes

then the other part as well but if you

see the movement I can hold my breath

and get it to go to clear

but then when I breathe again it goes to

detected showing movement but you know

the occupancy stays triggered but pretty

cool little thing you can do just off of

a sensor in the ceiling that's pretty

badass

how did I come to wanting to do my own

without you know buying something built

you know ready to go well I'd like to do

in my bathroom I like to have motion if

you've been around the channel you've

seen some of my little bathroom sensors

that I've done I put up in the ceiling

that have a PIR which is that passive

infrared and then you know you do have

the temperature humidity and that way

the humidity gets too high that you can

turn on the vent and that way you don't

have all that moisture build up which is

bad for your bathroom and it's fully

automated because you know your other

guests they don't turn the bathroom

vents on and their only problem with

that of course is uh if you sit very

still for some pirs then of course the

light turns off and if you're doing your

deed and everything and whatnot and yes

half I'm going to say what not for you

quite a lot and whatnot but especially

if the wife is taking a bath and just

soaking and you have the lights go off

yeah that's not a very good uh Waf this

one was the one I built a while back and

all I was doing was just taking a like

Decor face plate I know not everybody's

in the US but I could basically take

just a blank face plate whatever your

wiring standard is and then I have it in

a box up in my ceiling and I'm able to

run low voltage to it and then I just

have an ESP chip this is the esp8266 on

the bottom and I just have Dupont

connectors and if you're not sure you've

never seen duponts they're pretty damn

simple see these little jumpers these

are already pre-made there's no

soldering there's no white weird wiring

you know you just plugging and playing

and following a couple things of like

Hey where's the positive go where's the

negative go so these just pop on and pop

off

and that's pretty much that simple now

the only problem is if you do it a lot

you pull them on and off the little

spring will wear out but hey you can

take your um glue gun yeah this is a

wonderful little invention and throw

just a little dab of hot glue on it and

it will stay there until the next time

you have to pull it down and want to

maybe change it like we're doing here

now I have tried a lot of different damn

mm wave sensors and if you're not really

familiar with mm wave just think of it

as a radar sensor that detects if a

person is breathing or making those

little minute movements that a human you

know would typically make that would be

alive

and it picks up and you know you set

your sensitivity now if you don't want

to be you can't set it too sensitive and

then say some ceiling fans and

everything

but once you kind of get things tweaked

it works damn awesome the

ld1125 is around 10 to 12 U.S and it's a

pretty small size I mean look the

comparison of the ESP chip it's smaller

than it now the only thing that's going

to be weird about it is the pins on the

back you need the smaller I think

they're two millimeter but I probably

don't need to correct if I don't get the

size right there's some smaller Dupont

jumper ends and they do make these you

can made up already but you can see the

different size you can see the size is a

lot different

between the two different sizes of

DuPont jumpers but just make sure you

get the right jumpers for these versus

you know the regular style Dupont jumper

but you got to have them on either side

you get what I'm saying

so that way you can plug it straight up

to the

esp8266 or I went with esp32 because

there really isn't a reason to do 8266

unless you just have them around I

prefer to go esp32 and

these are pretty damn cool I found these

on Amazon I'm sure they're on AliExpress

and whatever I'll probably link them

around it's your regular

little old school micro USB this is

pretty cool because

this is the whole wire

you can take and it is if you can see

the stuff here probably look pretty

close you just gonna see the positive

and negative that way you could run

whatever wire over to it and you're like

a low voltage wire into that box and

then you could come up with your wire

here

and plug it in and go just like that now

I did mention humidity how the hell are

you going to get humidity Travis

well that's like this

there's some other sensors there's the

keep want to say the sht the 31 but

these little I squared C sensors they

just plug into some other pins on the

ESP chip and

there's a I like the BME the BME 280

works really well for humidity but

there's also the aht 21 that I've tested

and of course that sht31 and I'll leave

all that below some of them you can get

them pre-soldered but some of them do

not come with the pin headers soldered

on so just be aware that when you're

purchasing them this is what it looks

like from you know the it's I have it in

the ceiling and I probably will show a

picture here and this one I just have

the BME 280 in there and I just drill a

small hole as you can see there and

that's the only thing I have exposed is

the sensor of that four to pick up that

humidity

now this is going to look like ass but

hey I'm the only one that's going to see

it well I guess everyone out there as

well but

hot glue gun is your friend and yes you

may laugh I put had hot glue gun stuff

from different wall plates from like

capacitive touch buttons and everything

and stuff in the ceiling they've been up

through the Louisiana heat in the Attic

cooking for years

and perfectly fine and the other great

thing about it it's so easy to get one

of these at the hobby store or whatever

and then you can just glue the hell out

of it and it seals the chip right up so

you won't get any moisture on it or

whatever this one you can see I just

glued down the BME 280. I threw a little

glue on the little on the DuPont jumpers

that way they won't come off

and one thing you'll notice I did if you

can get on the camera is I angled I

threw a little glue underneath because

this is the chip here

and so these targets face down

and that's what you know all you're

seeing is this here

and the back of it well I threw a little

glue because I wanted the chip

to be at an angle if I'm trying to get

to my angles right

so I wanted to be at an angle because I

actually had an issue when I first put

it up that if we put your arm on the

back of the couch that was on that

adjacent wall well then it would set the

light off well so I angled it a little

bit and turned down some of the

sensitivity and was able to tweak it and

you know it works great I'm the only one

that sees it so I did throw a glue all

along the back of it to seal it and then

because in case the ESP chip came down

which is kind of impossible for it to do

that then it wouldn't

you know touch on it or whatnot and

there it is Dick for you again Heff it

just seals everything up and then I took

some I just put a dab of Super Glue on

on the DuPont jumpers on the board that

way it won't you know come off but

that's all up to you and how you want to

build it if you want to build something

that goes in the wall you want to build

something in a different 3D printed case

or whatever type of thing because you

know the mm wave think about it you

don't have to really see it like you did

a PIR sensor you could hide it in

something as long as it's not metal

because metal of course going to stop

that 24 gigahertz really well which is

not a bad thing if you're trying to hide

it from some ceiling fans you can

actually use some different metal pieces

and things to uh you know direct the

signal from being able to see a constant

moving device such as a computer fan or

ceiling fan or whatever else may be

moving in the room now the software

we're going to put on the ESP chips well

of course that is ESP home if you're

running home assistant a h a Os or

Docker or however you're running this

thing you can run ESP home there's tons

of different ways to install it add-ons

Docker do the whole deal it's pretty

much gonna all look and work the same

check out ESP home dot IO and you can go

show how to get started with it or

whatever

now once you do get that and come back

and see my boring ass talk

you should have this dashboard of ESP

home and that would be like in your

add-ons or whatever it's the web GUI 2

where you manage all the stuff and

there's still no dark mode

um yeah now we're just gonna make a new

device we're going to copy everything

into it no big deal let's just go

through here and we'll say continue and

we'll call it

esp32 radar video

whatever you want to call it I'm gonna

delete mine later

this is going to be esp32 I just hit

skip because you don't want to install

it right now and it should be somewhere

in your list I got a bunch of junk

um so they should just hit edit

and you should get the everything in

here now

we're just going to copy and paste

things over all this

so

I have all this I'll leave the link down

it'll come from our website if you

really just want to copy and paste it

you want to download it or whatever now

the code where this comes from I didn't

make it all just tweaked a few things it

came from the great kingpatrick 3399 he

has a bunch of these different models

all on his GitHub and he has all the the

yaml files and everything and the

manuals and how if you want to wire it

or whatever or the configuration the

settings pretty simple stuff uh but I'll

take the ones that I have tweaked and

I'll have them ready to go on my website

where you can just copy and paste those

if you like there's no dark mode here of

course and just after my eye surgery I'm

still kind of sensitive to light so I'm

just going to use notepad plus plus to

go over some of his code go ahead and

set your name now the update time I have

that for my humidity sensor I just just

have it wanting to check the humidity

temperature every 30 seconds I don't

need it more than that I added down here

the I squared C you can change those to

whatever you want as long as they're

valid pins

um everything else I left the same here

API if you want to throw an encryption

key in you're more than welcome to I use

these locally I didn't need an

encryption key nor the password you can

put those in there my Wi-Fi I do have

this set using my secrets because I need

static IPS for make mine work that well

if you don't need yours you can just

leave it back as default

which was this here it's just three

lines

you know Wi-Fi SSID and password I

didn't need the fallback access point

mode because it is just a ESP chip and I

can get to it fairly easy but if you

want to leave it in there and put in

their captive portal more than welcome

to see here's the RX pin and TX pin and

I'm using those for uart2 it's

recommended otherwise you will have

issues that's that tx2 and rx2 on the

esp32 then I added the BME 280 right

here for temperature pressure and

humidity where they don't really need

temperature so I I just don't add it to

the card in home assistant and I did use

the over sampling 2x I only needed it to

take two samples and then jump out I

didn't need I think the default's like

five or six and something crazy I didn't

need that does is it moist or not and

then the uart text I Le if you set this

internal as true you won't see this it's

more of a debug

but it's also more for the chip to sin

every time there's movement and that

could make things a little slower and

that's pretty much it the rest of it's

all Patrick's code from his GitHub so

definitely thanks to that for him

figuring all this crap out with this

sensor because it's really awesome that

you can tweak everything right in home

assistant in real time if you jump over

here to home assistant you're not sure

how to install on an esp32 chip in ESP

home if you look in the home assistant

side ESP home I have the full procedure

with screenshots on how to create your

little sensor like we just did and then

how to flash it install it most people

get worried about the word flash but

it's just writing it to the chip it's

installing it so we'll hit the install

button now the first time you do this

you do need to manually do it so I'm

gonna hit manual download

now you want to use modern format now it

will take some time to build depending

on what you're building this on just go

do something else and just come back and

check on him now if you change some

other things a little bit later a lot of

times it will just change that small

pieces and cache what it built and it'll

build a lot faster so once it's done

compiling it will automatically download

to the computer so don't delete that

file but if you head over and probably

the easiest one that's non-geeky is the

web installer for ESP home

and if you just look at you can go here

it says install ESP Home factory bin via

web browser that's on my website again

we're just going to go here now at this

point do plug in

point over here like you can see but you

can see I've got my USB cable plugged in

and I do need to plug that into the

computer should not but sometimes some

of the esp32s you do need to hold down

the boot Button while applying power for

a few seconds but most of them they you

don't have to do that so we'll go ahead

and try it with this one we'll go here

and oh look this works with dark mode

but it looks really really funky

whatever we're going to hit connect and

there it is

this is that cp2102 I think that's

another cable I probably have that come

30

so we'll hit connect

and we're going to say install and we

will choose the file that's gonna be the

file that just downloaded to your local

computer and that's gonna be that master

bath one I have built and hit install

and if everything went correct and your

thing is hooked up you should get the

erasing message and don't browse away I

know it's tempted to go browse to your

favorite YouTube websites and whatever

else just let it do the install and

we'll come right back it doesn't take

that long and I can actually see the

blue light the status LED blinking on me

so it's probably booting up by the time

I get done running my mouth if you come

back and jump into the ESP home

dashboard

we should see

a master bath potentially there it is

goes online

now the logs I think I have it turned

down where it doesn't spew out tons of

data because I found that that was you

know just bogging down that chip too

much but you can go turn on all those

debug and everything if you do have

issues but I can already see it found my

I squared C that's that BME 280 so I

should be good now let's go add it into

home assistant now a lot of times you'll

get a notification when you pull up home

assistant it'll Auto Discovery boom it's

great pretty awesome but I have to go in

and put mine manually you have to do

that I'm going into Integrations

and adding ESP home

and I'm putting in that IP address and

hit submit

there we go esp32 master bath and we'll

go ahead and we'll call it in the area

the master bathroom will be good at

doing that and hit finish

we should see it down here

there's a device give it a little bit

sometimes I have seen this page take a

little bit to load

and then we'll go ahead and we'll say

add to dashboard and you can see

everything's working got humidity you

got the temperature and the distance the

way this is laid out you can see now

this is my one that I have working and

tweaked and everything and you really

what's the cool thing about this is you

can go ahead and install this and you

can go sit there with your phone and

play with these little sliders and just

walk away let it re reset it re-triggers

come back in you can all do it in real

time unlike say some of those other

sensors this is pretty badass where you

can do all this now the MTH mth2 mth3

that's the different I guess the other

one I call it Gates but that's the

distance for sensitivity MTH 1 is 0 to

2.8 and then 2.8 to 8 and then eight and

I do believe the sensitivity

the higher you slide the slider is the

less sensitive it is see on this

particular one in this bathroom I got a

small bat front bathroom I didn't need

like eight meters of distance and I

didn't want it reading eight meters

because then that's going to go well

beyond that room and Trigger so I set

them all the way like don't be sensitive

at all

and then I even said this is the max

distance

I even set the max distance to 1.9

that's kind of I where I needed it to be

so I could catch the tub and it has

worked out well

now you're gonna play around with all

with yours there's also the movement

clearance time and then I think that's

the direction let me go back on let me

see what that is yeah move

occupied to clearance waiting time and

then move to occupied waiting time and

really you just got to go in and go play

around with these and watch the sensors

but it's not that crazy to do because

there's not a whole lot of stuff to mess

with really so it's pretty

simple to mess around with and then you

can drive all your automation straight

from it and I love this damn thing so

it's go build one dude it's it's badass

trust me it has changed stuff and it's

not that expensive to do

all right dude so we turned the blind

all right dude so we turn the clearance

time and the movement time way down now

I want you to go trick the light like

you did the last one go in there and try

to sit still

you can't do it can you

it stays triggered huh

come out

stop

come back right here it's cool and stuff
