Meanwhile the viewer "gadjet" has optimized and minimized the PCB. His impressive optimization has meanwhile gone through 5 phases of "evolution". But more importantly, he has reworked the code to ESP-Now, reducing the wake time of the ESP to 0.25 seconds. This extends the battery life immensely. Check out his great website and project on Github: gadjetsblog.blogspot.com/2022/03/the-many-versions… github.com/gadjet/Window-Door-sensor-Version-5 @gadjetsvideo Thanks for sharing your ideas and additions. I do my videos for people like you: Knowledge doubles when you share it.

I just ordered boards on the JLCPCB. Everything is OK. I liked it and immediately subscribed too ! Looking forward to see more of your videos.
-
I have never tried to solder smds, until now... What a great project! I rent a space that has a window that cant be left opened for long periods of time, this project fits my needs !!!
-
So much learning value in a single video, pure gold! Thanks for making this, really high quality project, supporting links and video production. Subscribed!
-
I've recently been working on a similar project with a wemos and tasmota, using tasmota deep sleep. Now I know why the battery wasn't lasting as long as expected. Your vid gives me good ideas. Thanks 😁
-
A true Renaissance man. Hats off to you my dear.
-
Very well done video, subscribed instantly! Keep it up!
-
You are a genius. Subscribed!
-
Awesome things you make!! and im also started to make a IoT-stack on my Synology NAS 920+ and docker, i have now installed all the packets, and expermiment with node-red with your video's im learning how that works.. very good videos!! (also with the help from the guy with swiss accent hihi)
-
Great video! Just trying to learn all I can about the ESP8266 and ESP32, hardest part is figuring out what I actually want to build!
-
Awesome tutorial 🔥
-
Ein wirklich angenehmes Video 👍😊 Mein Abo hast du 😉
-
Great video! 👍👍
-
Cool video, thanks :)
-
Nice and interesting video. I liked it and immediately subscribed too ! Looking forward to see more of your videos.
-
AWESOME 👍 I was searching for it for awhile, hungry ESP ruined my real wireless battery powered projects, I will try it as soon as possible
-
that intro music was not expected. You just blew my mind. 10/10.
-
Great! I've an ESP8266 and I use it for IoT WiFi
-
Realy cool project! Was looking to make something similar but from "modules" and it will take too much space. Your solution is really pretty! One stuff I will update there and it will be that every time it send information about "On/Off" switch, it could send capacity/voltage information about battery. That you will be able to see when you should prepare for battery change. But I understand that if I will put 4000mAh LiIon, that I will dont need to change it for few years :D
