Every time a smart-home vendor raises subscription prices or bricks a hub, the Home Assistant community grows a little more. Nanoleaf, Wyze, and Aqara have all had bad years. If you already run Home Assistant and want to stop renting features you already own, seven integrations cover the biggest hosted apps people ditch first. We tested each on a Home Assistant Green box and lined them up by what they actually replace.
Six of these are free and open source. One is a $6.50/month cloud service from the Home Assistant maintainers themselves, and it is worth paying for if remote access matters.
What to look for in a Home Assistant integration
The best integrations are the ones you stop noticing after setup week.
- Local control (no vendor cloud in the loop)
- Actively maintained on GitHub and in HACS
- Documented Blueprint automations
- Reasonable RAM and CPU footprint on a Raspberry Pi 4 or NUC
- Works with Voice PE, Assist, or your voice tooling of choice
- Restore from backup on a fresh install without hand-editing YAML
Local control is the reason people move to Home Assistant in the first place. Anything that phones home to a vendor cloud belongs in a different article.

The apps
1. Home Assistant, the base of everything
Home Assistant is the platform every integration on this list plugs into. Version 2026.1 shipped Zigbee 2 protocol updates and Matter over Thread improvements. The mobile companion apps have caught up to any commercial smart-home app for daily use.
Where it falls short: the learning curve is real. First-time users spend a weekend on setup. Blueprints help, but writing your first automation still touches YAML.
Pricing:
- Free and open source
- Home Assistant Green hardware around $99 if you do not want to source your own
- Home Assistant Yellow at $150 for a Pi-based upgrade
Platforms: Linux (Docker or HA OS), also Windows and macOS via Docker
Download: Home Assistant
Bottom line: install this first. Everything else in this article is a plugin.
2. ESPHome, best for DIY sensors and switches
ESPHome flashes ESP32 and ESP8266 boards with a YAML-driven firmware that speaks Home Assistant natively. A $5 ESP32 becomes a temperature sensor, a leak detector, a garage door opener, or a Bluetooth proxy. The 2026 release added Matter output, so ESPHome devices show up in Apple Home and Google Home natively.
Where it falls short: hardware fluency is required. If you have never touched a soldering iron, expect a learning curve.
Pricing:
- Free and open source
- Hardware ranges from $3 (ESP-01) to $15 (ESP32 with battery)
Platforms: Windows, macOS, Linux (Docker, HA add-on, or CLI)
Download: ESPHome
Bottom line: the pick for anyone who wants to replace vendor-locked sensors with a $5 board.
3. HACS, best for community add-ons
HACS (Home Assistant Community Store) is the app store for integrations that are not in the core catalog. Alexa Media Player, SmartTub, Xiaomi Mi Home, and hundreds more live here. Installation is one click after HACS itself is set up.
Where it falls short: HACS integrations can break on Home Assistant point releases. Read the notes before upgrading.
Pricing:
- Free and open source
- No premium tier
Platforms: any Home Assistant install
Download: HACS
Bottom line: install right after Home Assistant. Everything gets easier.
4. Zigbee2MQTT, best for vendor-agnostic Zigbee
Zigbee2MQTT replaces every vendor-specific Zigbee hub in one integration. Ikea Tradfri, Aqara, Philips Hue, Innr, and hundreds of others all speak to Home Assistant through one Sonoff or ConBee stick.
Where it falls short: requires a Zigbee stick and MQTT broker. If you only have three Hue bulbs, the native Hue integration is simpler.
Pricing:
- Free and open source
- Zigbee stick hardware around $25 to $40 (Sonoff Zigbee Dongle-E is the community pick)
Platforms: Windows, macOS, Linux (HA add-on, Docker, or CLI)
Download: Zigbee2MQTT
Bottom line: install once you own more than one brand of Zigbee device.
5. Node-RED, best for visual automation
Node-RED replaces YAML automations with a flow-based visual editor. Trigger on a motion sensor, wait five minutes, check if the sun is up, publish an MQTT message to a light. Every step is a node, and the visual graph is easier to reason about than YAML for complex flows.
Where it falls short: not everyone likes visual programming. Debugging Node-RED flows is different from debugging YAML.
Pricing:
- Free and open source
- Ships as a Home Assistant add-on
Platforms: any Home Assistant install (add-on) or standalone on Windows, macOS, Linux
Download: Node-RED
Bottom line: install if you write more than five automations and want a visual view of them.
6. Frigate NVR, best for local AI camera
Frigate is a network video recorder with local AI object detection. Point your cameras at Frigate, tell it to detect people or cars, and Home Assistant fires an event when a person walks up your driveway. No cloud, no monthly Ring bill.
Where it falls short: needs a Coral USB stick or a modern GPU for real-time detection. On a Pi 4 with no accelerator, detection lags.
Pricing:
- Free and open source
- Frigate+ (better models): $12/mo
- Google Coral USB accelerator around $60
Platforms: Windows, macOS, Linux (Docker or HA add-on)
Download: Frigate
Bottom line: install this to replace Ring, Wyze, or Nest recording.
7. Music Assistant, best for multi-room audio
Music Assistant replaces Sonos, Yamaha MusicCast, and every proprietary multi-room app with a single Home Assistant integration. It streams from Spotify, Apple Music, Tidal, YouTube Music, and local files to Sonos, Chromecast, Snapcast, DLNA, Airplay, and Squeezebox targets.
Where it falls short: still a newer project. Some Spotify features (crossfade, gapless) work only via Spotify Connect, and the plugin catalogue is smaller than Sonos.
Pricing:
- Free and open source
- Spotify Connect requires a Spotify Premium account
Platforms: Windows, macOS, Linux (HA add-on or standalone Docker)
Download: Music Assistant
Bottom line: install if you have three or more speakers from different brands.
8. Nabu Casa Cloud, best for remote access and voice
Nabu Casa Cloud is the only paid integration on this list, and it is run by the Home Assistant maintainers. For $6.50/month you get remote access without opening a port, Alexa and Google Assistant integration, and voice assistant infra that keeps working when the internet blips.
Where it falls short: it is a subscription. Alternatives (WireGuard, Tailscale) are free but require more setup and self-hosting discipline.
Pricing:
- $6.50/mo (billed monthly)
- $65/year (billed annually, saves about 17%)
- 30-day free trial with no credit card
Platforms: works with any Home Assistant install
Download: Nabu Casa
Bottom line: the pick if you want remote access and voice control without configuring a VPN, and the money goes to the people who write Home Assistant.
How to pick the right one
If you want the simplest option: install Home Assistant + HACS + Nabu Casa Cloud, and stop there. If you have DIY hardware skills: add ESPHome and Zigbee2MQTT. If you write complex automations: add Node-RED. If you already own IP cameras: add Frigate. If you own multiple smart speakers: add Music Assistant.
Local control is the theme. Every integration on this list keeps working when the internet is down, except Nabu Casa Cloud (which only handles remote access and voice). If a vendor turns off their servers tomorrow, none of these break.
FAQ
What is the best Home Assistant integration to install first?
HACS. Once HACS is running, every other integration on this list is one click away, including some that never make it into the core catalog.
Can I run Home Assistant without a Raspberry Pi?
Yes. Home Assistant runs on any Docker host, including a mini PC, a Synology NAS, or a Windows or macOS machine. The Green and Yellow appliances are convenient but not required.
Which Home Assistant integration replaces Ring?
Frigate NVR with a compatible IP camera. Setup takes a weekend, and after that you own the entire recording pipeline with no monthly fee.
Do I need to know YAML to use Home Assistant?
Not to start. The UI covers most beginner automations. Blueprints let you install community-written automations without touching YAML. Node-RED covers the complex cases.
Is Nabu Casa Cloud safe to trust?
Nabu Casa is run by the Home Assistant Open Home Foundation and the developers of Home Assistant itself. Their remote access is a WireGuard-based tunnel; the credentials and traffic never touch a third party.
