I'm backwoods camping next week, and we have 25 people spread out over three sites. I was thinking it would be funny to bring some old rotary dial phones and some sort of way of hooking them up, and then just have that as the intercom between sites for when dinner is ready or whatever.

It's next week, so unlikely to happen and I'm not sure what technology I would need to make it all work. Something like Lora plus a way to make the phones work.

Cheap FRS walkie-talkies, can find plenty of these on ebay if don't want to buy new (will need new batteries though).

> What is it about AC that makes it impossible to control?

Nothing; there is something about my AC and the badly hand-assembled ESP8266 and IR transmitter I made that doesn't work.

I was able to record/playback fujitsu mini-split commands using a simple wemos d1 IR shield + wemos d1 mini (esp8266) a few years ago.

Phones charge on fire resistant tile. I only use the other building for stuff with removable batteries which phones sadly aren't. If the phones had removable batteries I'd just get an extra set an swap with the ones on the charger when they run low.

I've been thinking of finding some kind of fire resistant box for phone charging though, so that's what I was hoping to find at the link. :)

I feel like I'm being mocked for having a widescreen monitor.

nah, just rotate your monitor 90 degrees (or 270).

What I wish I had known: HA is just a python program, it's pretty easy to run it manually.

After my Pi's sdcard died, I wanted to use an old laptop (more reliable with a built-in backup battery) so I followed the deployment recommendations and used the VM image. After that, for the first time I started having problems with HA not running - because VirtualBox would run only about a month before crashing. And I didn't like how much memory a VM locked up on the host.

The documentation makes it sound super complicated, but if you can make a venv and `pip install`, the setup is that easy. I tend to just run `hass` manually but there instructions for setting up supervised. I wish the documentation made this clearer, it really tries to scare people away from that method but running a whole VM is a lot of overhead for my pretty simple zwave-js setup.

Have HA running without any issue on a Linux KVM VM.

I wish FEIT devices were compatible. I've seen their smart bulbs at costco for as low as $2.50/ea.

Costco Feit WiFi dimmers can be flashed with esphome with some work, have a few dozen running. Haven't tried the bulbs.

I'm sure you know but for others reading, 12v ws2811 are grouped in threes, so not individually addressable. 5v is, and when you're working at scale power injection isn't a huge deal as you'll be doing it anyway.

Always standardise your connectors. I'm a fan of the Ray Wu ones.

ESP/WLED driven is my preference, but the Falcon controllers are popular amongst people who are more DIY/woodworking oriented as they're much simpler to set up and not _heaps_ more expensive. Falcon Player/xlights is the standard software for designing/playback of your show regardless of hardware.

Coro props (corrugated plastic, corflute) are a cheap and effective way to stand out from the crowd. Animatronics, smoke etc are also an option when going more advanced.

It's a lot of work. You rarely want to start after October or order your goods after July. You are running a live production and things will go wrong. Good luck to anyone entering the space, it's very fun and expensive!

There's multiple types. I use the bullet type regulated 12V ws2812 for outdoor applications and they are individually addressed. I also use 12V ws2812 RGBCW (RGB+white cold+white warm) unregulated (resistor) led strips which are grouped in threes for indoor. Both work just fine with wled or custom software (e.g. micropython / C++ ) on esp32.

Kindergarten is free in the US. Also the vast majority of people pay a relatively small amount of their income for health insurance (and of course it’s free for 65+ who are the primary consumers).

Kindergarten is preschool which means at least daycare, it's not free in the US , I think there's a confusion with elementary school, to which there's a public option. Also forgetting the fact there's no universal parent leave in the US compared with the very generous many months elsewhere, which also makes a huge difference to new parents. There's no possible comparison...

In ALL of the great lakes, 45 people drowned last year. I have no idea what the drownings near shore was, but I mean, millions of people live on the borders of the Great lakes. 45 is pretty damn good and I think resources are better spent on other things.
