My "dumb" freezer can now text me if I leave it open too long

- I got tired of my freezer door getting stuck and my food melting, so I quickly (and very cheaply) rigged up a system to alert me if the door stays open for more than a few minutes.

I love how professional this is, hope your following grows fast!
Turns out I may have lied re: WiFi / Bluetooth coexistence on the ESP-32. It appears you can do it, but there are some limitations since they share a radio.
This is a lot of work to solve a problem that would be solved by a spacer on the wall.... Just the way we like it! Nice job.
Came here to say the same thing 😂
Thinking the same, nothing wrong with IOT-ing your stuff, but fix the god dam problem..
Love it, Guy! Some freezers beep when left opened ... BUT - some people, “ah-hem”, over a certain age, “ah-hem’, may not be able to HEAR it, “ah-hem.” Keep up the good work. Necessity has always been, and will always be, the mother of invention. 👍
I have a fridge that beeps when left open... but not if you leave it slightly open! Very annoying because it can still warm the inside over time!
this channel is so underated
This is awesome! Really cool content.
Thanks Justin!
You could use a Normally Closed reed switch and External Wake up to make the battery last longer because the pin would be high only when the door is open. Then it’s always in deep sleep until the door opens so you wouldn’t have to use a timer wake up.
I thought about this, and I think you're right - I could save some battery. But I'd still need a way to distinguish between false positives (freezer door open for appropriate time) and accidental meltdowns. I'd still need a timer. so I just preferred to keep the logic super simple knowing that in context it would take a long time to kill that battery. Also I didn't have any NC switches sitting around lol
Also I think I read somewhere that setting an external interrupt uses slightly more current than timer based sleep but I could be totally wrong on that
Good thought tho! Thanks

Awesome content! Thank you for putting the effort into making these videos. Keep going, you’re wonderful!
Thank you so much!
nice vids dude, keep em coming and you'll get a lot of subs for sure
Good video but i would lower the music level relative to the voice.
So far reed switches can switch enough current so you could use them between controller and power supply.
谢谢您的启发，这非常酷
you're welcome!!
30 seconds in, why won't you just move the fridge a inch from the wall?
1minute in, *"..that would be boring youtube video.."* true. true. proceeds to watch :)
Could you make the ESP32 wakeup only when the door is opened, by use of "External wakeup"? Then do a 3 min sleep and re-check. This way the battery might last much longer.
Yup, an interrupt would totally work. I think I was trying to keep it more "noob" friendly, but I'm not sure I even accomplished that 😁
Although actually now that I think of it - I think keeping an interrupt active may actually prevent you from entering the "deepest" sleep on the ESP. vaguely remember seeing that? Could be totally wrong though
Very cool ! Does this work with any kind of „switch“ ?
Yes. Any kind of electrical switch should work!
Aren't you protecting yourself from the smoke coming from soldering?
I have one of those fans with a filter attached, I don't use it all the time though 😬. I know I should.
@@GuyDupont Take care and create a lot of awesome content for long time ;)
