Ring Intercom – Door won’t open automatically (Siedle 1+n)
Hi everyone,
I’m using three Ring Intercoms with different door systems, all connected to Home Assistant.
Each system uses the exact same automation to automatically unlock the door when someone rings.
Two systems work perfectly, but system 3 (Siedle HTS 811-0, digital 1+n) doesn’t open the door, even though the ring event is detected.
Setup Overview
| System | Door Unit | Intercom Type | Signal Type | Status |
|---|---|---|---|---|
| 1 | Gira 125003 | Type 2 | Analog 2-wire |  Works |
| 2 | Siedle AIB 150-01 | Type 2 | Analog 2-wire | Works |
| 3 | Siedle HTS 811-0 | Type 3 | Digital 1 + n Bus |  Doesn’t open |
All devices are online, on the same Ring account, firmware up to date, with good Wi-Fi signal.
Manual operation through the Ring App works perfectly.
Home Assistant Automation (same for all)
alias: Auto-unlock on ring
trigger:
- platform: state
entity_id: event.system3_ring
to: "on"
action:
- service: button.press
target:
entity_id: button.system3_door_open
- delay: "00:00:03"
Issue Description
- The ring event (
event.system3_ring) is correctly triggered and visible in Home Assistant. - The automation action (
button.system3_door_open) also executes normally — shown in the trace. - The Ring App even displays “Door opened”.
- But the physical door doesn’t unlock.
- When I manually press the unlock button in Home Assistant or in the Ring App, the door opens instantly.
Everything else (connectivity, app control, manual button press) works fine —
only the automatic unlock sequence right after ringing fails on the Siedle 1+n system.
Has anyone else experienced this with Ring Intercom + Siedle HTS 811-0 (Type 3 / 1+n Bus) where the unlock command does not actually open the door even though all triggers fire correctly?
Thanks!
