What Sentinel watches

What Sentinel actually monitors.

Temperature trend

Monitors temperature trend on your hot tub pipework — detecting significant drops and cooling patterns that suggest a heating issue — before it affects your guests.

Heating activity

Analyses power consumption patterns to identify when heating activity appears to have stopped or become abnormal.

Power loss

Detects loss of power to the hot tub. Where Sentinel maintains its own connection, you're notified promptly. A site internet failure will also trigger an offline alert.

Freeze risk

Ambient temperature monitoring for plant rooms and equipment areas during cold weather.

Access alert

Optional sensor for equipment areas or secure enclosures — know if someone's been in.

Connectivity check

Regular heartbeat from every Sentinel unit. If a unit goes offline — whether from a power cut, internet failure or hardware fault — you're notified. Note: distinguishing between broadband failure and complete power loss requires a UPS-backed connection.

How it works

Simple hardware.

Sentinel hardware is installed at your property by us. It monitors temperature trends, power consumption and connectivity, with optional leak and access sensors available. It operates independently without interfering with your hot tub's existing controls. When a configured threshold is crossed, an alert is sent directly to your phone.

When Sentinel is paired with a TopTubs maintenance contract, we can receive the same alerts. This allows us to investigate developing issues quickly, often before the property owner or guest becomes aware of them.

Sentinel is currently in development, with pilot installations planned across Lincolnshire and surrounding areas. Register your interest and we'll be in touch as the first installations roll out — early registrations are prioritised.

Who benefits most

Great for anyone who
can't check in daily.

Holiday let operators

A fault found at changeover is already too late. Sentinel means you know before the guest arrives.

Remote properties

If you're not at the property regularly, Sentinel gives you confidence that everything's fine.

Lodge and glamping parks

Monitor multiple units from one place. Sentinel Commercial supports multi-tub dashboards with per-unit status, alerts and history.

Domestic peace of mind

For hot tub owners who want to protect their investment, especially through winter.
