I love playing with my HA and associated devices. I suspect that most of you reading this get a bit of a jolt every time you add and incorporate a new sensor, camera, integration and get to play with it.
I have all the door/window sensors and locks/covers, every angle of my exterior covered with cameras, alarm, network devices, appliances, sprinklers, household devices covered.
Any ideas for a new thing I can play with?
3D printing is half the fun! Although I have no skills in design so I usually look for STLs that other have created. The NFC tag reader was such a fun project because I got to: 3D print the enclosure, solder the wiring for the ESP and NFC hardware, write the login within Node Red to work as a juke box, and then I wrote an excel file that I use to track my playlists (allows me to copy/paste the Spotify share link and have it translate it into an NFC tag payload).
