Best Self-Hosted Home automation Tools

Self-hosted home automation keeps your lights, sensors and switches under your own control instead of behind a vendor cloud. The four picks here are different layers, so decide which you are missing. Home Assistant and openHAB are the hubs: they connect your devices and run the automations. Home Assistant is the larger community project; openHAB is a pure Java platform built on OSGi, where bindings connect different bus systems, hardware devices and protocols, and it ships stable, milestone and snapshot Docker images. ESPHome sits on the device side: it turns ESP32, ESP8266 and similar microcontrollers into devices from YAML configuration files, with a dashboard to manage them. Eclipse Mosquitto is an MQTT broker with no web interface, the message hub that devices and hubs publish to and subscribe from. Most setups pair one hub with a broker and, if you build your own devices, ESPHome. Whichever hub you run, keep it off the public internet and back up its configuration folder.

ESPHome

A system to control ESP32, ESP8266, BK72xx, RP2040 and similar microcontrollers from simple configuration files and manage them from home-automation systems such as Home Assistant, a project of the Open Home Foundation. The Docker image runs the ESPHome dashboard (Device Builder), the web UI for managing device configurations.

Home automation

openHAB

A vendor-neutral home automation platform: the open Home Automation Bus connects different bus systems, hardware devices and interface protocols through bindings, adds automation logic across those system boundaries, and offers user interfaces for it. A pure Java solution built on OSGi, published as Docker images in stable, milestone and snapshot channels.
