Best Zigbee Temperature & Humidity Sensor (2026): We Tested 4

Fri, 18 Sep 2026 00:00:00 +0000

Short answer: The Sonoff SNZB-02D is the best all-rounder in 2026 — accurate, reliable, and it shows temperature and humidity on a small display. For pure value, the classic Aqara WSDCGQ11LM is still unbeatable.

Temperature and humidity sensors are the quiet workhorses of any smart home. They feed your climate automations, warn you about mould risk, and trigger your radiator valves. We run sensors in every room of our house on a single Zigbee network — this guide reflects what survived months of real use.

Best Smart Plug Under €20 (2026): We Tested 5

Thu, 17 Sep 2026 00:00:00 +0000

Short answer: The IKEA TRETAKT is the best budget Zigbee plug in 2026 — tiny, reliable, and often under €10. If you want energy monitoring, the Sonoff S60ZBTPF is the best value under €20. Both work perfectly with Zigbee2MQTT and Home Assistant.

A smart plug is the best first purchase for any smart home. It turns a dumb lamp, heater or coffee machine into something you can control from your phone, automate on a schedule, or trigger from a sensor. We run over a dozen plugs on our Zigbee network, so this advice comes from daily use, not spec sheets.

How to Add a Non-Wi-Fi Mitsubishi AC to Home Assistant (2026)

Thu, 17 Sep 2026 00:00:00 +0000

Short answer: if you have a ducted Mitsubishi AC with a wired, Wi-Fi-less wall thermostat, skip the expensive MelCloud adapter. A ±€10 ESP32 plugged into the unit’s CN105 service port gives Home Assistant full, local control — the same features as the wall thermostat, plus energy metering and room temperature. This guide is research-based: the build was documented by Iván Gómez Arnedo (Sep 2026) on a Mitsubishi SEZ-M60DA2 ducted unit [1], and we validated the approach against the official ESPHome documentation [2].

Best Zigbee Coordinator for Home Assistant (2026)

Sat, 12 Sep 2026 00:00:00 +0000

Short answer: For most Home Assistant users in 2026, the Sonoff ZBDongle-E is the best Zigbee coordinator — cheap (~$20–27), rock solid, and the de-facto standard for Zigbee2MQTT. If your server sits in a noisy closet and you have 30+ devices, the SMLIGHT SLZB-06 (Ethernet/PoE) is worth the jump.

We run 46 Zigbee devices on a ZBDongle-E in our own home, so this ranking comes from a live network, not spec sheets.

From AI Overkill to Smart Simplicity: Automating Your Sectional Garage Door

Fri, 11 Sep 2026 00:00:00 +0000

The Problem: Overthinking Garage Door Status

My client initially approached me with a common smart home challenge: how to reliably track their garage door’s status – open, closed, and moving. Their first thought was to leverage their existing Frigate AI setup, which already handled object detection and motion sensing through a Coral TPU. While Frigate is excellent for detecting general motion or specific objects like cars, using it to definitively determine ‘open’ versus ‘closed’ when the door is stationary, or even its exact movement phase, proved surprisingly complex. The standard detection model lacked a ‘garage door’ label, meaning it couldn’t inherently distinguish between an open door and a closed door if both were static.

How We Migrated 5 Years of Home Assistant History (400M+ Rows) to a Dedicated InfluxDB VM

Fri, 11 Sep 2026 00:00:00 +0000

The short version: We moved five years of Home Assistant history — more than 400 million data points — out of the InfluxDB 1.x add-on and onto a dedicated InfluxDB 2.x server, without losing a single point and without rewriting a single Grafana dashboard. Three phases, one seam, zero drama.

This is the story of that migration: how we planned it in phases, which pitfalls nearly bit us, and what we’d do differently if we had to do it again (and what we’d do exactly the same).

Home Assistant & Zigbee: The Open-Source Path to Smart Lighting

Sat, 29 Aug 2026 00:00:00 +0000

Embracing Local Control and Privacy

Proprietary smart lighting systems often lock users into specific brands and cloud services, raising concerns about data privacy and long-term device compatibility. Home Assistant, paired with the Zigbee protocol, offers a robust open-source alternative. This setup centralizes control on a local server, typically a Raspberry Pi, eliminating reliance on manufacturer clouds. Zigbee, a low-power wireless mesh network standard, ensures devices communicate directly with your hub, enhancing responsiveness and network stability. For those prioritizing data security and system longevity, this combination provides a powerful foundation for managing home lights independently, ensuring your data remains within your home network.

Smartening the Season: Zigbee Christmas Lights with Home Assistant

Sat, 29 Aug 2026 00:00:00 +0000

The Power of Zigbee for Festive Displays

Traditional Christmas lights, while charming, often lack convenience. Integrating Zigbee-enabled smart plugs or dedicated light strips with Home Assistant transforms your festive display into an intelligent, responsive system. Unlike Wi-Fi alternatives, Zigbee operates on a mesh network, offering superior reliability, wider coverage, and local control – meaning your lights respond instantly, even if your internet connection falters. This robust foundation is crucial for seasonal setups that demand consistent performance throughout the holidays, ensuring your decorations operate precisely as intended without reliance on external cloud services.

How I Migrated 46 Zigbee Devices to a New Coordinator Without Re-pairing a Single One

Tue, 25 Aug 2026 00:00:00 +0000

The short version: In one afternoon I moved our entire Zigbee network — 46 devices — from an ageing Z-Stack stick to a Sonoff ZBDongle-E, and every single device came online without one re-pair. It sounds like magic, but it’s just three things done right: the firmware, the backup format, and one crucial EUI step most guides forget.

This is the exact story, including the mistakes we made, so you can skip them.

Zigbee vs Z-Wave: Which Protocol Should You Choose in 2026?

Tue, 25 Aug 2026 00:00:00 +0000

Short answer: For most Home Assistant users, Zigbee is the better choice in 2026 — more device options, lower prices and a bigger ecosystem. Z-Wave still wins where range and network congestion matter, especially in dense homes.

We run both protocols live in our own smart home (46+ Zigbee devices and a separate Z-Wave test network), so this comparison is based on real-world use, not spec sheets.

Why this matters

Your protocol choice locks in your entire ecosystem. You cannot mix Zigbee and Z-Wave devices in one mesh without a second coordinator, so it’s worth getting this right before buying your first sensors.
