Party Squasher Review: Occupancy Monitoring for STR Party Prevention (2026)
Overview
Party Squasher is an occupancy monitor for short‑term rentals that counts mobile devices around a property to detect crowd‑size gatherings and alert you before a party gets noisy. A small sensor plugs into the router and uses Wi‑Fi probe signals (no mics or cameras) to estimate how many people are present, sending SMS/email alerts when thresholds are exceeded.
- Standard is best for single homes via mobile app; Pro adds a web dashboard, portfolio grouping and an API for PMS integrations. First‑year pricing (sensor + subscription) is $249 Standard or $309 Pro, with renewals at $199 and $252/year respectively and volume discounts from 10 to 250+ units.
At a glance
- Device‑count based occupancy monitoring: Party Squasher tracks the approximate number of people at a property by counting nearby mobile devices using Wi‑Fi probe signals, even when devices are not connected to the home network.
- Pre‑noise party prevention: by alerting you when occupancy exceeds a set limit (e.g., 12 devices) before people get loud, you can intervene early to avoid neighbor complaints, fines, damage and delisting, going beyond traditional noise monitors.
- Privacy‑friendly design: the system does not record audio, use cameras, or store personal data or phone numbers; it’s been certified GDPR‑compliant and uses patented techniques to preserve privacy while still signaling crowd size.
- Property managers and teams
- Hosts who want a clean UI
- Automation-first workflows
- Best suited for detached or single‑family homes; the device’s detection radius can pick up neighboring apartments, so it’s not ideal for dense multi‑unit buildings where multiple units share walls.
- Annual subscription model with per‑device hardware purchase can be expensive versus some subscription‑only competitors, especially for hosts who want both noise and occupancy monitoring.
Pros & Cons
Highlights and considerations for Party Squasher.

- Pro‑grade multi‑property tools: Party Squasher Pro adds a web dashboard to group homes by geography, risk level or manager, plus an API so PMs can integrate occupancy alerts into PMS tools and combine data with noise monitors or smart locks.
- Clear hardware + subscription pricing with volume discounts: Standard and Pro include the sensor and first‑year subscription ($249 and $309 retail) with renewals at $199 and $252/year and reduced per‑unit pricing down to $119–$149 first‑year and $108–$132 renewals for 250–499 properties.
- Best suited for detached or single‑family homes; the device’s detection radius can pick up neighboring apartments, so it’s not ideal for dense multi‑unit buildings where multiple units share walls.
- Annual subscription model with per‑device hardware purchase can be expensive versus some subscription‑only competitors, especially for hosts who want both noise and occupancy monitoring.
- It estimates occupancy based on device count (phones, tablets, wearables) rather than actual headcount; couples sharing devices or guests with multiple devices can skew numbers up or down, so thresholds need tuning.
- No built‑in noise monitoring; for full party risk coverage, most PMs will pair Party Squasher with a separate noise monitor and/or camera at the entrance.
- Dashboard and API are only available on Pro; Standard is mobile‑app only, which limits multi‑property oversight without upgrading.
Scores
Strong in setup and alert automation; weaker in detection methods for security and monitoring.
