An open house is the cheapest viewing an agency ever runs: one trip, one hour, several buyers. The hard part is filling it. The Open House add-on handles that by sending an automatic alert to exactly the people who already told you they want this kind of property — users whose saved search matches a property about to hold a viewing.
The property form gains an Open House card. Each row is a slot with a start date/time and an end date/time. A property can hold as many slots as needed — a Saturday morning and a Sunday afternoon, or four consecutive weekends.
Slots are structured data, not a free-text line. That is what makes everything else possible: the listing can order and filter by them, the property page knows which slot is next, and the alert knows what is coming up within the next seven days. Slots are also stored as a CSV column, so a full season of viewings can be prepared in a spreadsheet and imported in one go.
Past slots stop appearing on their own — there is nothing to tidy up after an event.
Visitors can register for a slot directly from the property page. The admin sees the attendee list per slot, giving a clear picture of expected turnout before attending.
Go to Configuration → Add-ons → Open House alerts to configure the alert email.

| Setting | Description |
|---|---|
| Subject and body | The text of the alert email sent to matched users. |
| Per-event row template | Controls how each individual open-house slot is rendered inside that email. |
The alert is sent to users whose saved search matches a property scheduling an open house within the next seven days, and only to those who have alerts switched on. It is dispatched by the site's scheduled job.
