I put together an esp32 + accelerometer in a little 3d printed box. Made two sets and taped one of each on my washer and dryer, now they detect the start and end of a cycle and send me a notification through home assistant. The tablet in the kitchen get a notification too and makes a special sound when the clothes are done!

Oh I like that. We have LG washer and dryer but I have 0 interest in connecting then to Wi-Fi. Right now we have a z-wave button sitting on the washing machine that starts a timer when we press it, but since the washing machine has variable run times, it's imperfect.

We have a "smart" washer & dryer, and the Alexa voice announcement when the cycle finishes is handy.

It works pretty well, and it's nice having full control of the smarts. My washer and dryer don't have a built in buzzer for some weird reason, so it's been a nice upgrade.

I want to build a house-positioning system, but time, energy, and skill are lacking. My wife, who has pretty extreme ADD, loses stuff like her wallet, keys, etc. We have Tiles on most stuff that gets lost, but sometimes the volume of the alert is lacking. I'd like something that uses multiple ESP32 or Pi receivers in known locations to triangulate the position of the bluetooth beacon in 3D space. It's probably a bad…

I've put a bunch of rPI zeroes throughout the house with varying degrees of success. Works best with the home assistant beacon on my Galaxy watch, it's likely tile tags will work better. The only downside is that the PIs require an external Bluetooth dongle hooked with a USB extender, because of wifi interference.

I used raspberry so I can use room-assistant for home assistant. You could probably hack it up with a bunch of ESPs and a central server to aggregate it all. Then trilateration should be fairly simple.

Does a raspberry zero count? I replaced the dubiously secure Chinese box that came with my solar panels with a home grown energy monitoring solution, hooked up to HomeAssistant. And I made a full color eInk photo frame that displays seasonally appropriate, generated images from a stable diffusion like-algo.

Which colour e-ink panel did you use? Any pictures of your setup?

An Inky 7.3 inch, pimoroni sells them. Pretty good, but the colors are cleary muted and it aggressively dithers (only 7 different ink colors in pixel)

I made an overly greasy movie to impress hiring managers on linkedin, should actually do a writeup and make some photos of the thing in its proper wooden frame...

Also I run a fine tuned stable diffusion nowadays through Replicate ai, it now creates scenes starring my kids' pluche toys. Live view of the latest generation at the index page...

I built my own personal weather station when Wunderground was destroyed by TWC and IBM. It has continued to grow over the last two years. With each new idea I have, I have been adding additional functionality to it. It's fun and I've learnt a lot because multiple programming languages are needed to get everything to function.
