Philips sold you a smart bulb.

It is not your smart bulb.

To turn it on with your phone, you have to buy the Philips Hue Bridge. The old Bridge V2: $69.99. The new Bridge Pro released September 2025: $98.99.

Then the Bridge Pro adds a subscription. Security alerts on MotionAware cost $1 a month or $10 a year on top of the hardware you already bought.

In December 2015, Philips pushed a firmware update that blocked every third-party Zigbee bulb from working with the Hue Bridge. GE, Cree, Osram. Bulbs people already owned. Philips reversed the block after public outrage, but the message was clear. The Bridge is theirs.

Then Samsung retired the original SmartThings hub on June 30, 2021. Every device set up on it stopped working. Samsung offered a $35 discount toward a new Aeotec hub with no migration path.

Then Aqara sells you a hub. IKEA Tradfri sells you a hub. Google Nest Hub. Amazon Echo Show. Every ecosystem gets a $60 to $150 box that only speaks to its own bulbs.

You are paying for a translator between two devices sitting six feet apart in 2026.

Now meet Zigbee2MQTT.

A free and open source bridge that lets you control any Zigbee device from any brand without the vendor's hub. Plug a $20 USB Zigbee dongle into a Raspberry Pi, install Zigbee2MQTT, and pair Hue, Aqara, IKEA Tradfri, Sonoff, Innr, Sengled, and 4,000+ other devices directly. No Hue Bridge. No SmartThings hub. No cloud. No subscription.

Built by Koen Kanters in the Netherlands. First commit April 2018.

- Full local control of 4,000+ Zigbee devices
- No cloud, no vendor account, no phone-home
- Native Home Assistant integration
- Works with OpenHAB, Node-RED, and any MQTT broker
- Web interface for pairing and grouping
- Automations that keep working when your internet is down

Here is what Zigbee2MQTT costs:

Zero. Forever.

Philips charges $69.99 for the Hue Bridge. Zigbee2MQTT doesn't.
Philips charges $98.99 for the Hue Bridge Pro. Zigbee2MQTT doesn't.
Samsung retired the original SmartThings hub in 2021. Zigbee2MQTT doesn't retire.
Every brand sells a $30 to $60 hub. Zigbee2MQTT replaces them all with one USB stick.

For one household with Hue, Aqara, and IKEA bulbs, you save the cost of three separate hubs.
For every Zigbee bulb you already own, you save the risk of a vendor lockout.

Your bulbs. Your sensors. Your network.
