Configuration

Settings → Devices & Services → Add Integration → search "htd", "lync", "lync6" or "lync12" → HTD Lync Pro.

Connection Settings
Network gateway (GW-SL1) Gateway IP, port 10006
Direct RS-232 Device path, e.g. /dev/ttyUSB0

The integration auto-detects the model (Lync 6 / Lync 12), the firmware, and pulls zone names and source names from the unit — devices are created with your real room names.

Changing the gateway IP later

Integration entry → ⋮ → Reconfigure. Never delete/re-add — that would create new entities and break automations. Reconfigure keeps everything.

Options (integration entry → Configure)

Option Default Meaning
Polling interval 0 0 = push only. N seconds adds periodic full polls. Manual refresh always available (Refresh button / htd_lync_pro.refresh).
Doorbell restore on Restore zone power/source/volume after the doorbell chime.
Max power-on volume 0 Clamp a zone that turns on louder than this (keypad 0-60). 0 = off.
Quiet-hours volume / window 0, 22:00–07:00 Tighter power-on cap during the window.
Announcement player / TTS entity Defaults for htd_lync_pro.announce.
Tone encoding signed Leave on signed for firmware v3.

One client at a time

The GW-SL1 gateway serves one TCP client. Don't point two Home Assistant instances (or HA + the HTD app in serial-bridge mode) at it simultaneously.
