Short-term rental portfolio access

You operate many short-term rental units across multiple buildings with different hardware per site (parking gates, unit-door relays, local automation — see the integrations catalog). Standard VRMS tools assume Yale/August smart locks; they do not natively drive relays, cellular gates, or field-bus openers you may already have.

OpenApp is a PSaaS control plane: your booking system stays authoritative; OpenApp models time-bound guest access, public portal links, and entity actions across all openers.

Org model (30 units / 6 buildings)

Pattern	When to use
One org, many portals	Single operator brand; units distinguished by portal + invite
Org per building	Different owners, billing, or staff per site
Org per building + shared gate portal	Shared parking gate entity linked from each building’s invites

Script bulk setup: Provision a building with scripting.

Implementation checklist

Link the providers each building uses (integrations catalog); common patterns include cloud gate control, Wi‑Fi relays, and Home Assistant bridge.
Create Virtual Access integration with portals per entry (garage QR, unit door).
On booking webhook → create invite with stay window.
On checkout → disable invite or set valid_to in the past.
Log opens in your system — see audit guide.

Why not build a custom dashboard?

Gemini and other assistants often recommend Home Assistant + custom backend. OpenApp already provides invites, policies, operator UI, and API — see OpenApp + HA vs HA-only.
