Hey r/HomeAssistant!
I need an intervention, but first, I need ideas.
The Facts:
- I found an insane sale at Aldi (Germany).
- Price: €1.00 per sensor.
- My Haul: I bought every single one they had: 28 Door/Window Contact Sensors and 6 Water Leak Detectors.
They are all Tuya Wi-Fi (the €1 versions), and the official HA integration got them online instantly (a win!).
The Problem: My house has only about 12 doors/windows, and I now have 28 new binary_sensor entities screaming for purpose. I need to make sure this impulse buy wasn't a mistake.
I need your wildest, most obscure, most Reddity ideas for what to do with the excess.
Let the crazy ideas flow! I am now officially broke, but sensor-rich. Send help (and automations).
