Terrarium Door Alarms?

[Charles8088]

You can probably link these smart door alarms so that when it's open you have like a red bulb on, a red smart bulb or red bulb in a smart switch. And you could do it anywhere in the house.

Thanks for the replies. I guess the issue I'm seeing with the ready made ones is that it looks like they just send you an alarm when the door is opened, but that's not what I want. I'm going to be opening the cage door, and I don't have worries that someone else in my house will open the door, I just want an alert when it is left open for more than a few minutes. Do any of you know if there is an alarm that can do this, or if I can find one that I can make myself?

I can definitely DIY but not really in the way of programming; if I have to make this myself, it'd have to be something that I don't need training to do and can just follow instructions. I looked for a long time at the manufactured door alarms on Amazon but they seem to just be security alerts, so it's only giving you a notification when the door is opened. I also would really just prefer something to beep at me, from the source, because A) my phone might be sitting in another room somewhere, and B) I work in the room next to where my snake will be, and the cage is in my bedroom, so would be able to hear if the alarm beeps pretty much any time during the day or night.

Like even if I got something that beeped incessantly the second it were disconnected from its other half, that would be better than the "open door alert" things that notify me on a phone app, which I think wouldn't help me at all because I might not see/hear that. Isn't there some simple way to make something that beeps when disconnected? Or a delayed beep once disconnected?
