diyHue

Last reviewed Sep 13, 2026 · 833 words

The trap with diyHue is that it must own ports 80 and 443 on a real IP address on your LAN, because that is where every Hue app and integration expects to find a bridge. It also needs host networking for SSDP and mDNS discovery. So the box you were planning to share with your reverse proxy is the wrong box, and the first hour of most failed diyHue installs is spent discovering this. Give it a dedicated Raspberry Pi, a VM with its own IP, or a macvlan interface in Docker, and the rest of the project is pleasant.

What the emulator actually does

diyHue is MIT-licensed Python, first released in 2017, with 1,818 GitHub stars at the time of writing, and it presents itself to the network as a Philips Hue Bridge. The official Hue app, third-party Hue apps, and anything with a Hue integration (Home Assistant, Logitech Harmony, Alexa, most smart-home hubs) will pair with it as if it were Signify's hardware. Behind that API it translates commands to whatever lights you actually own: WLED strips, Tasmota and ESPHome bulbs, Yeelight, Shelly, IKEA Trådfri via a gateway, Zigbee bulbs through deCONZ or Zigbee2MQTT, and its own native firmware for ESP8266 boards. It can even link to a real Hue bridge and fold those lights in.

The pitch is a 60 dollar bridge you do not have to buy, and a way to put a 12 dollar WLED strip into a Hue scene next to real Hue bulbs. It runs comfortably on 128 MB of RAM and idles at nothing.

Host networking is not negotiable

Run it in Docker like this, adjusting the interface name and MAC to the host's:

services:
  diyhue:
    image: diyhue/core:latest
    network_mode: host
    environment:
      - MAC=dc:a6:32:11:22:33
      - IP=192.168.1.40
    volumes:
      - ./diyhue-config:/opt/hue-emulator/config
    restart: unless-stopped

The MAC value becomes the bridge ID that apps use to recognise the bridge, so changing it later makes every paired app forget the bridge. Set it once. If you cannot spare the host's port 80 and 443, a Docker macvlan network gives the container its own IP on the LAN; that is the pattern I use, and it means my Caddy instance keeps its ports.

The first time you open the Hue app you press the "link button" in diyHue's web interface, which lives on the same port 80, for 30 seconds to authorise pairing. That page is also where you add lights, group them into rooms, and set up entertainment areas.

Compatibility quirks arrive with app updates

The honest con is that diyHue chases Signify. When the Hue app tightens its certificate checks or adds a new API version, diyHue tends to break for that app version until a release catches up, which can take days or weeks. The Hue integration in Home Assistant is more forgiving than the phone app and rarely breaks. Hue Entertainment, the low-latency streaming used for Hue Sync and gaming effects, works well with WLED and the native ESP firmware and poorly or not at all with slower protocols like Yeelight.

So decide what you are optimising for. If the goal is "the Hue app controls all my lights", accept occasional breakage and pin the container image rather than pulling latest. If the goal is "my Hue-only accessories and Hue-only apps can reach my cheap lights", it is stable enough to forget about.

Where it sits relative to Home Assistant

diyHue is not an automation platform and does not want to be. It has no automations, no scheduling beyond what the Hue app offers, and no device support beyond lights and a handful of switches and sensors. Most people who run it already have Home Assistant and use diyHue for one of two reasons: a Hue-compatible accessory (a dimmer switch, a Sync Box, a Harmony remote) that needs a bridge, or a family member who likes the Hue app and refuses to learn another one.

If you have neither, skip diyHue and put WLED and Zigbee2MQTT straight into Home Assistant, which supports both natively with fewer moving parts. The home automation category is the right place to compare the larger platforms; diyHue is a bridge into one ecosystem, not a replacement for any of them.

What I'd do

A Raspberry Pi Zero 2 W or a macvlan container, diyHue pinned to a known-good tag, WLED and ESPHome lights added through its interface, and Home Assistant pointed at it through the standard Hue integration. I would use the Hue app for scenes and the family, Home Assistant for automations, and never let diyHue be the only path to a light I need at 2 a.m. Treat it as a compatibility shim for the Hue ecosystem, budget an hour when the Hue app updates, and it earns its place.
