Case for WLAN mousetrap alert

Have you mice on your attic too?
And you won't slay or poison these mice?
But if you are placing a live catch trap there and you will forget it so they will starve in a long way. Also not better.

Therfore i have upgraded a live trap from amazon with a little circuit which sends via WLAN / internet a message to my telegram-bot.

(See the demonstration video here: https://youtu.be/tJTT1gJi4og)

Telegram is my preferred social app. It's easy to create a bot there for your own ideas, so it's simple to send your bot a message with an URL called by any device.

Because the attics have mostly no LAN-cable i am using the WLAN in my house. So a IOT device with WLAN is needed. I am using 'Wemos D1 mini', it costs not more than 4 dollars from china.

The genious idea of this project is, that the trap needs no current! If you are powering WLAN-chipsets to wait for closing the trap, you have to charge the batteries (AA/AAA) all 4 days.
So my idea is not to power the device at all:
