What Party Squasher actually is
Party Squasher is a hardware occupancy sensor that counts mobile devices every 20 seconds and alerts property managers when occupancy exceeds a preset threshold. Unlike noise monitors, it detects large gatherings proactively — before noise complaints or damage occur. The 2.3″ sensor plugs into USB power, covers an entire detached home including yards, and collects no personal data. It is designed exclusively for detached, standalone properties; shared-wall buildings produce unreliable readings.
Core features
- Occupancy counting via mobile device detection every 20 seconds
- Customizable occupancy threshold alerts
- Whole-property coverage including front and back yards from a single sensor
- Tamper-resistant design with disconnect notifications within 15 minutes
- Privacy-first — no microphones, cameras, or personal data collection
- GDPR compliant
- Pro plan adds web dashboard and API access
Pros
- Detects parties before they escalate by counting occupancy, not reacting to noise
- Privacy-first — no microphones, cameras, or personal data collected
- Zero-maintenance hardware with whole-property coverage from a locked closet
Cons
- Only works reliably for detached homes — shared-wall properties get false positives from neighbors' devices
- Counts devices, not people — guests with multiple phones overcount, airplane mode undercounts
- Occupancy-only — does not monitor noise, smoke, or other property risks
Best for
Operators managing detached-home portfolios who want proactive party prevention via occupancy counting rather than reactive noise monitoring
Not for
Anyone managing condos, townhouses, apartments, or multi-unit / shared-wall properties — the sensor cannot distinguish your unit from neighbors

Small portfolios
Works well if your 1–3 properties are detached homes, but $249/sensor year-1 cost is steep when you're watching every dollar.

Mid-sized portfolios
This is Party Squasher's sweet spot — volume discounts kick in at 10 sensors and detached-home portfolios get proactive party prevention across every property.

20–100 listings
Large portfolios
Volume pricing kicks in at 10+ sensors, and party prevention ROI scales with reservation volume. For 20–100 detached-home portfolios, Party Squasher is a clear fit — provided none of your units are shared-wall.

Airbnb primary
Airbnb-first hosts
Adds a proactive party-prevention layer that Airbnb's built-in anti-party tech doesn't provide, but only if your listings are detached homes.

Vrbo primary
Vrbo-first hosts
Vrbo skews toward detached vacation homes, making more of your portfolio eligible — but you're still paying per-sensor on top of Vrbo's host fees.

3+ channels
Multi-channel operators
Hardware-based and channel-agnostic, so it works regardless of where bookings come from — but the detached-home requirement limits which properties you can deploy it on.
