home assistant

In a win for modular, private, local IoT, I just upgraded my Home Assistant Yellow from a Raspberry Pi Compute Module 4 to a Compute Module 5 this morning, and got an instant 2x speed boost.

I first posted about the Yellow in 2022, and walked through my smart-but-private HA Yellow setup in my Studio in a video last year.

Because I was running an eMMC CM4 in the Yellow before, I ran a full backup (and downloaded it), yanked the CM4, flashed HAOS to a new NVMe SSD, and plugged that and the CM5 into my Yellow. After running a Restore (it's a handy option right on the first page that appears when you access homeassistant.local), I was up and running like there was no difference at all—just everything was a little more snappy.

After a decade, Raspberry Pi finally upgraded their official Touch Display from 480p to 720p, while keeping the price and overall aesthetic the same.

I've had early access to the Touch Display 2, and have been testing it in a variety of scenarios. Generally, Linux touchscreen support isn't wonderful. And Pi OS, being a fairly customized UI focused on simple use cases, is not quite to a usable state if you go touchscreen-only, considering I had trouble getting the onscreen keyboard to work in Chromium half the time, and it would overlay things I was typing even in fully-supported apps like Terminal.

There are far too many smart home devices which make using a device harder. Like a light switch and light bulb that requires a wireless connection to a hub in order to control the lights.

Before, you could flick a switch, and a light would come on.

Now, you have to ensure the light has power, the switch has power, and the hub has power. And the wireless connection between switch, hub, and light needs to be reliable. And the hub can't lock up or go offline. And if it's anything like most modern IoT devices, the hub needs a reliable Internet connection and cloud account, or things will start failing at some point.

That's dumb.

And that's just light switches. Can you imagine relying on this kind of 'smarts' for essential services in your home, like HVAC, water supply, etc.?

To be truly 'smart', I follow three principles for home automation. Every smart device must be:

A couple weeks ago, I glanced through my ever-growing collection of Raspberry Pi RP2040-based boards—pictured above are three of the boards I've tested: a Cytron Maker Pi RP2040, a Raspberry Pi Pico, and a Seeed Studio Wio RP2040.

I've dipped my toes in 'smart home' automation in the past.

Typically I approach 'smart' and 'IoT' devices as a solution to one simple problem, instead of trying to do 'all the things'.

For example, I wanted to make it easy for my kids to control a home theater with four different devices and complex audio/visual routing, so I bought a Harmony remote and programmed it to control TV, a game console, an Apple TV, and radio. I don't want Logitech to start controlling other aspects of my house, or to give intruders an avenue by which they could invade my home's network.

However, many smart devices require a persistent Internet connection to use them, and that I cannot abide.
