Question 1

What is Domoticz?

Accepted Answer

Domoticz is a lightweight home automation system for monitoring and controlling lights, switches, sensors, and more from one web interface. It supports the protocols real smart-home hardware uses — Z-Wave, MQTT, RFXCOM, and others — offers rule-based automation, and logs sensor history.

Question 2

Which port does it use and what's the login?

Accepted Answer

Domoticz runs on host port 8284, mapped from the container's 8080. Critically, it starts with no authentication configured — there's no default login because there's no login at all until you set one.

Question 3

Can it use my Z-Wave USB stick?

Accepted Answer

Yes, but the USB controller has to be passed through to the container. A Z-Wave or Zigbee stick plugged into the host isn't automatically visible inside Docker — the compose configuration needs to map that USB device into the container.

Question 4

How does it compare to Home Assistant?

Accepted Answer

Home Assistant is far more capable — more integrations, a polished interface, a bigger community, and stronger automations — but it's much heavier and wants more resources. Domoticz is deliberately lightweight and runs well on hardware where Home Assistant would struggle.

Question 5

Does it work without internet?

Accepted Answer

Yes — that's a core benefit. Domoticz talks to your Z-Wave, MQTT, and RFXCOM devices locally and directly, with no manufacturer cloud in the loop, so your automations and control keep working even when your internet connection is down.
