Dude. Brother was founded in 1908.

All of my wall sockets include usb power outlets, so they’re all powered via those, I’m currently working on using an 18650 or 2 to power one as an experiment, but as they’re WiFi and need to react in a timely manner putting the microcontroller into sleep mode isn’t really an option, meaning the battery life won’t be very good. The RADAR module needs a solid 5v as well so I’m not sure it will be practical.

This is the sensor module: https://www.aliexpress.com/item/1005005921080708.html?spm=a2g0n.order_detail.order_detail_item.3.496af19cSQkowI

This is the microcontroller: https://www.aliexpress.com/item/1005006018009983.html

This is the project on GitHub I use for the HA integration: https://github.com/Chreece/LD2411S-ESPHome

And the case I use is on this project for a very similar setup to mine: https://github.com/igiannakas/mmWave-Presense-Sensor-D1-Mini-DFRobot-/tree/main

I build my own using EspHome. I tend to use a D1 Mini as the microcontroller as it has a small footprint and a LD2411S sensor module (very cheap on AliExpress ) I’m lucky enough to have a 3d printer to make my own enclosures.

I moved all of my movement/presence sensors to mm wave RADAR, they’re relatively cheap and much more reliable than PIR.

If you’re investing in a car, you’re either obnoxiously rich or don’t know what the word investing means.

Please do this Elon, so we can finally let this dumpster fire burn out and move on.

Surely the best approach here is a temp sensor with a threshold at which to alarm? Then you’re actually monitoring the state of the appliance, not the state of the door.
