SwitchBot makes a better fan

I was already a big fan of SwitchBot's big circulator fan I recently reviewed, and now we're getting the SwitchBot Battery Circulator Fan 2 Pro. Priced at $119.99, it ditches the height-adjustable stand but increases battery life, throw distance, and wind speed while adding native Matter-over-Wi-Fi, allowing it to join your smart home without needing […]

KNX Motion-Sensor Automations in Home Assistant

A note before the post: the mistake in the first section is genuinely mine. It cost me an evening of forking conditions in Home Assistant before I accepted the fix didn't belong in Home Assistant at all. I've left it in rather than writing around it, because it's the part I'd have wanted to read first. The first time motion-controlled lighting actually worked in my place, it didn't feel clever. It felt obvious — I walked into a dark hallway and the light was already on by the time I'd registered it was dark. That's the bar. Not smart , just attentive. Getting there with seven KNX motion sensors took me less code than I expected and one insight I wish I'd had on day one. This is Part 05 of the series. The earlier parts cover the boring-but-load-bearing groundwork: running Home Assistant in Docker and wiring up HACS . Here I'm assuming HA is up, talking KNX, and you just want the lights to behave. One sensor, two jobs, two addresses Here's the mistake I made, and it's the whole reason this post exists. KNX exposes each motion sensor to Home Assistant as a binary_sensor with device_class: motion , fed by a KNX group-address state object you configure in knx.yaml with a state_address per sensor. Simple enough. So I wired all seven sensors with one group address each and pointed both the lighting automation and the presence logic at the same signal. That works right up until you want the two to behave differently. A light should react to the smallest twitch, instantly, generously. Presence and security want the opposite: a debounce, a grace window, some scepticism before they commit. When both ride the same group address, every change you make to one quietly deforms the other. I spent an evening forking conditions in Home Assistant trying to make one signal mean two things. The fix isn't in Home Assistant at all. It's in ETS: give each physical PIR a second group address . One drives comfort lighting, the other feeds presence and the alarm path. I use a flat convention —

I never ran ESXi in production

Most "why Proxmox" content in 2025-2026 is a migration story driven by Broadcom's ESXi pricing changes. The author had a working VMware stack and got priced out. I'm not that author. I evaluated both, picked Proxmox in 2024, and built on it without ever running ESXi in production. Two years in, I'd make the same call. It reads as either incompetent or contrarian until the rest of the post lands. Here's the reasoning. The three reasons it was the easy call 1. LXC and KVM in one host Most workloads in this homelab are LXCs. Pi-hole, Vaultwarden, Authelia, Traefik, the monitoring stack, GitLab CE itself, all containers sharing the host kernel. A few things need full VM isolation (the NAS guest, Proxmox Backup Server, the Home Assistant OS appliance). Same hypervisor, same CLI, same web UI for both shapes of workload. The alternative is ESXi for the VMs and a separate toolchain (containerd, Docker, Kubernetes, take your pick) for the containers. That's two backup pipelines, two HA stories, two places for config drift to surprise you at 2 AM. pct exec 254 systemctl status authelia and qm start 189 are the same shape. New hires don't have to learn one tool for containers and a different one for VMs. 2. Proxmox Backup Server beats the free Veeam alternative Chunk-level deduplication. Backups across guests and across time share storage. A nightly backup of all 11 LXCs and 2 VMs runs in about ten minutes and adds a few hundred MB of new chunks, because most of the content is the same as yesterday. Cluster-scheduled. One job definition runs across every node in the cluster. No per-node cron, no manual rotation when a node moves. Restore to a different storage class. A backup taken from local-lvm on the G7 restores onto ZFS on a G5 cluster node without conversion gymnastics. Veeam Community Edition is the free comparison. It works. It also caps repository size, doesn't dedup at the chunk level, and lacks the cluster-aware scheduling that makes PBS feel like a built-in feature
