Not all Home Assistant integrations are created equal. Some route commands through manufacturer cloud servers, introducing latency and a single point of failure. These 12 integrations communicate entirely within your local network — no cloud, no internet dependency, no subscription.
1. Zigbee Home Automation (ZHA)
ZHA is Home Assistant built-in Zigbee integration. Pair a USB Zigbee coordinator and you have direct, local control of thousands of Zigbee devices — sensors, bulbs, switches, and plugs — with zero cloud involvement. Response times under 100ms are common.
2. Z-Wave JS
The official Z-Wave integration for Home Assistant. All communication happens locally via your Z-Wave USB stick. Excellent for door locks, thermostats, and security devices that demand reliability.
3. Frigate NVR
Full-featured local network video recorder with AI-powered person, vehicle, and animal detection — entirely on your hardware. Integrates deeply with Home Assistant for automations like “send camera clip when person detected at front door.”
4. ESPHome
Flash cheap ESP32 or ESP8266 microcontrollers to create custom sensors, switches, and controllers that communicate directly with Home Assistant via local API. Build your own temperature sensor, soil moisture monitor, or custom button panel for a few dollars.
5. Shelly
Shelly smart relays, dimmers, and plugs support a local REST API and MQTT — no Shelly cloud account needed. Install them behind existing switches to add smart control without rewiring. The local API is fully supported in Home Assistant.
6. MQTT (Mosquitto)
Run a local MQTT broker (Mosquitto is available as a Home Assistant add-on). Any MQTT-compatible device — Zigbee2MQTT, Tasmota-flashed devices, ESPHome sensors — publishes and subscribes locally. MQTT is the backbone of many local smart home setups.
7. Tasmota
Open-source firmware for ESP8266/ESP32-based smart plugs and switches. Tasmota communicates via local MQTT or HTTP, completely bypassing manufacturer clouds. Turns a $10 smart plug into a fully local, privacy-respecting device.
8. Philips Hue (Local Polling)
The Hue integration in Home Assistant communicates with the Hue Bridge on your local network — not through Philips cloud. No internet required for Hue control once the integration is set up.
9. Local Calendar
Home Assistant local calendar integration stores events on your Home Assistant instance. Use it to trigger automations based on scheduled events without relying on Google Calendar or any external service.
10. Wyoming (Local Voice Assistant)
The Wyoming integration powers Home Assistant local voice assistant pipeline using Whisper (speech recognition) and Piper (text-to-speech). 100% on-device processing — your voice commands never leave your home.
11. Bluetooth
Home Assistant can detect and integrate Bluetooth devices — including Bluetooth thermometers (Govee, Xiaomi), presence detection via phone Bluetooth, and various sensors. All processing is local.
12. Local Network Device Monitoring
Home Assistant can monitor your printer ink levels, NAS drive health, router status, and dozens of local network services — all without internet access. The integration library at home-assistant.io/integrations shows the full breadth of local options.
How to Check If an Integration Is Local
When viewing an integration in Home Assistant, look for the IoT class indicator. Look for “Local Push” or “Local Polling” — these communicate locally. Avoid “Cloud Push” or “Cloud Polling” if local control is your priority.
