Automation

Pair Restic with Rclone and you get client-side AES-256 encryption, smart deduplication, and a backend that talks to 70 plus cloud providers. A systemd timer and a short wrapper script handle the schedule. The result runs unattended, prunes old snapshots on its own, and lets you swap clouds by editing one config line. A tuned setup backs up 500 GB in under five minutes and costs as little as $3 a month on Backblaze B2.

On February 26, 2026, Claude Code ran terraform destroy against a stale state file. It wiped 2.5 years of DataTalks.Club production data: the RDS database, VPC, ECS cluster, load balancers, and every automated snapshot. Four cascading failures, each one preventable, took down a platform serving 100,000 learners.

Alexey Grigorev runs DataTalks.Club , a data engineering school with over 100,000 learners. He lost 1,943,200 rows of homework, project entries, and leaderboard scores when Claude Code ran the command against his whole production stack. The database, the VPC, the ECS cluster, load balancers, bastion host, and every automated snapshot were gone in seconds.

Just is the best general command runner for most new projects in 2026. It has Make-like syntax without the tab headaches. It works across Linux, macOS, and Windows. It stays out of your way as a command runner, not a build system. Task wins if your team prefers YAML and you want built-in file watching. Make is still right when you have real file-based compile dependencies or a Makefile that works fine.

Home Assistant pulls hourly spot prices through the Tibber integration or the Nordpool HACS add-on. It then schedules EV chargers, water heaters, heat pumps, and dishwashers during the cheapest hours. On a 2026 Nordic tariff with 3-8x daily price swings, shifting 10-15 kWh of flexible load each day cuts the bill by 20-40% with no comfort cost.

Why Dynamic Pricing Pays Off in 2026

The Nordpool day-ahead auction closes around noon CET. By 13:00, prices for all 24 hours of the next day are out for every bidding zone. That window is exactly what Home Assistant needs: a once-a-day drop of 24 hourly prices that your automations can plan against overnight.

Yes, you can monitor every houseplant in your home for under $10 per plant. A single ESP32 board running ESPHome (currently at version 2026.3.0) reads capacitive soil moisture sensors, a BH1750 light sensor, and an AHT20 temperature/humidity sensor, then feeds everything straight into Home Assistant . From there, automations send you a notification when a plant needs water, dashboards show moisture trends over weeks, and you stop guessing whether that fern in the corner is actually happy. This guide covers sensor selection, wiring a 4-plant monitoring hub, the complete ESPHome YAML configuration, Home Assistant dashboards, and tips for long-term reliability.

Pool and hot tub chemistry can swing from safe to damaging in a few hours. A paper strip you dip once a week will not catch it. The fix is cheap: a waterproof ESPHome sensor built around an ESP32 , reading water temperature, pH, and ORP, piped into Home Assistant for pump schedules, chemical alerts, and cover reminders. A full setup runs under $80. It replaces guesswork with a live dashboard and push alerts that fire before your heater corrodes.
