Connect Home Assistant with HACS Official

After these 3 steps, Home Assistant appears in seenzus as a Connected Source and begins syncing devices and state.

Install HACS → Install Bridge → Pair in seenzus

Before you start

Prepare your GitHub account and confirm that GitHub and this address both open:

http://homeassistant.local:8123

If the default address works, you do not need the HA IP. Only find the HA IP if it does not open.

1. Install HACS Official

Add HACS in Home Assistant and finish device authorization on GitHub.

Done when: GitHub authorization is complete and HACS appears in the Home Assistant sidebar.

Registration keeps failing

Restart Home Assistant and check GitHub connectivity. After three failures, Donggua HAOS users can switch to the HACS Turbo complete setup.

2. Install seenzus MQTT Bridge

Copy this one-click URL and open it in your browser:

http://homeassistant.local:8123/_my_redirect/hacs_repository?owner=walllbf&repository=seenzus-mqtt-bridge&category=integration

Only replace homeassistant.local with the HA IP if the default address does not open.

Open the one-click URL, download Bridge, then restart Home Assistant.

Done when: Bridge has downloaded and you have followed the final video step to restart all of Home Assistant. Refreshing the page is not a restart.

If the one-click URL fails, see other Bridge installation methods.

3. Return to seenzus and pair

Open Integrations → Add Source → Pair in seenzus. Start here instead of searching manually in Home Assistant.

Choose Quick Pair (recommended) in Home Assistant, sign in to seenzus, and approve the request. No MQTT settings are required.

Return to seenzus and open the Home Assistant Source you just created. Setup is complete when it shows Connected and begins discovering devices.
