Web USB and Web Bluetooth are amazing. I've used the former for the excellent Web MiniDisc [1], and the latter to flash custom firmware [2] on cheap Xiaomi Bluetooth LE thermometer/hygrometer devices that Home Assistant can pick up. Truly opening new possibilities, since I wouldn't have been comfortable running some sketchy script or local binary. [1] https://web.minidisc.wiki/ [2] https://github.com/pvvx/ATC_MiThermometer

For things that need to be stand-alone I'd first check if there's an existing off-the-shelf option first which generally would be more cost-effective to buy and look better than anything I could make myself. For temp sensors specifically I generally just go with whatever off-the-shelf stuff is supported by this firmware: https://github.com/pvvx/ATC_MiThermometer - as a bonus they can run on battery for a year or more.

I've been using a Raspberry Pi as a home server, and it's been holding up amazingly well, given everything I've thrown at it: - The excellent Home Assistant, for unifying across Homekit and Google Home and tracking historical temperatures and a couple of automations. The RPi has Bluetooth built in, so I can capture the data from a few Bluetooth thermometer/hygrometers running custom firmware (https://github.com/pvvx/ATC_MiThermometer) without a 802.15.4 bridge or similar. - An AirPlay to Google Cast bridge, mainly for listening to Overcast or the occasional YouTube video on Google speakers (without subscribing to Youtube Premium/Music) - A SMB server, for file storage and potential Time Machine backups (but I don't currently have enough storage, and locally attached SSDs are just hard to beat in terms of performance) - A DLNA server, for

watching photos and videos on my TV - Tailscale, for the occasional use of my home connection as a VPN when traveling (really glad to be having symmetric fiber for this!) - Caddy, as a frontend for everything web facing, to benefit from its excellent Let's Encrypt integration for automatic certificate requests and renewals Most of this is running in Docker containers and configured via Ansible, so that if the microSD card burns out (or I botch an OS update), I can just flash a new one with an empty image and recover from there.

This is great news, the Matter protocol sounds like it will make things a lot easier in the future. If you're looking to get started with home automation, I would recommend using Home Assistant as the central software to control everything. Matter seems to solve some issues that I don't really experience as a Home Assistant user. You can use Home Assistant as the gateway that connects all your hubs and devices together. I would also highly recommend buying Zigbee products from AliExpress. These are far more affordable than anything that you find in a retail store or from big brands. If you're very wealthy then you could afford to go with Philips Hue products for everything, but I've had a lot of success with some very affordable Zigbee and Bluetooth devices. Here's the products I would recommend (all prices in USD): * XIAOMI Mijia Bluetoo

I was worried that I'd be constantly changing batteries, but some of my motion and door sensors have lasted for over 2 years on a single CR2032 battery.
