Exploring the Key Features and Differences of the SenseAnywhere and WatchmanOne Real-Time Monitoring Systems

Selecting the right Real-time Monitoring System is a key decision for food production sites, as it directly affects product quality, regulatory compliance, and the ability to minimise operational risks.

Two widely used systems are WatchmanOne and SenseAnywhere, both designed to deliver continuous monitoring, automated alerts, and secure data capture.

While they share many core capabilities, these systems differ in areas such as connectivity, infrastructure, sensor performance, and cost.

This article outlines the key similarities and differences between the two systems. Click here if you would prefer to jump straight to the comparison table.

Key Features

Before we take a look at the main differences between SenseAnywhere and WatchmanOne, let’s review the key features that both systems have in common. As you can see, we’ve broken them down into seven different categories.

Core Monitoring & Alerts

  • Both systems continuously monitor temperatures and generate instant alerts when limits are breached.
  • Configurable alarm thresholds, delays, alerts can be set per location/equipment type.
  • Both systems send email and SMS alarms direct to personnel (SMS pricing varies).
  • Users can acknowledge alarms, add reasons, and document corrective actions. This is key for audit compliance.

Hardware & Sensors

  • The IP67 waterproof sensors are designed for wet, chilled, and hygienic food environments.
  • Option to add multi-parameter sensors and event monitoring (i.e. door sensors, oven temperature, water meters, compressed air meters, energy monitoring).

Compliance & Certification

  • Both SenseAnywhere and WatchmanOne provide acceptable digital records to ensure compliance with BRCGS and retailer audit standards.
  • UKAS and on-site calibration support.

Data Storage & Traceability

  • Both platforms store full temperature histories, with visual graphs and exportable audit trails.
  • Every reading, alarm, and user action is timestamped and stored.

User Access & System Control

  • Browser, mobile and app access from any device (desktop, tablet, mobile), with secure login.
  • Multi-user access and permission control, supports multiple users with different roles (e.g. QA, Ops, Technical).

Connectivity & Reliability

  • SenseAnywhere and WatchmanOne use robust 868 MHz radio communication. They do not rely on Wi-Fi or mobile networks, giving improved range and reliability through fridges, freezers, and thick walls.

Deployment & Scalability

  • No specialist installation required. Wireless magnetic/self-adhesive sensors eliminate cabling, drilling, or electrical work.
  • Scalable across multi-site operations, both systems can expand to large sensor networks and multiple sites.

Key Differences

Now for the key differences between the SenseAnywhere and WatchmanOne systems. We’ve grouped them into three different categories: 1. Connectivity & Infrastructure, 2. Sensors, Battery Life & Power, 3. Cost. You can also click here to jump ahead to our Overview Table.

1. Connectivity & Infrastructure 

When comparing Real-time Monitoring Systems, connectivity and infrastructure play a critical role in how reliably alarms are delivered, how data is accessed, and how the system is going to fit into your site’s existing setup.

SenseAnywhere WatchmanOne
  • Fully cloud-based with small access points requiring ethernet and mains power
  • No local display or audible alarm
  • Relies on alarm notifications only
  • 1 software licence per sensor
  • Hybrid connection (local LAN with cloud viewing via My Data Portal)
  • 1 software licence per site
  • Physical base station with live LCD display
  • Built-in sounder (additional on-site alarm layer)
  • Repeaters available to extend range (mains power only, no ethernet)
  • Ideal for operations needing both on-site and cloud alarming

2. Sensors, Battery Life & Power 

Differences in how frequently sensors transmit data, how long they operate before intervention is needed, and whether batteries can be replaced or require full unit replacement can all have a significant impact on both operational efficiency and lifecycle costs.

SenseAnywhere WatchmanOne
  • Communicates every 5 minutes
  • Extremely long battery life (up to 10 years)
  • Non-replaceable battery – when depleted, the whole sensor is replaced
  • Potentially higher long-term (10+ years) device cost due to replacement
  • Communicates every 1 minute
  • 3–5 year battery life depending on conditions (e.g. freezers ~3 years)
  • Replaceable batteries, so sensors are not disposable
  • Lower long-term ownership cost with no full sensor replacement required

3. Cost Summary  

Cost is often a key deciding factor, but it’s important to look beyond the initial purchase price and consider the overall cost structure of each system. Differences in licensing models, sensor pricing, and ongoing fees can affect the total cost of ownership over time.

  • +5 sensors (6 total)
  • +4 credits (6 total)
  • +2 APs (3 total)
  • 4-sensor starter kit (base station + 4 sensors)
  • +2 sensors (6 total)
  • 2 repeaters
  • 1 My Data Portal licence
  • 8-sensor starter kit (base station + 8 sensors + repeater)
  • 1 extra repeater
Costs
  • Total initial cost: £1,895.56 (inc. 1-year licence)
  • Annual cost: £24.53 per sensor (£147.18)
  • SMS: £0.61 per message
  • Total initial cost: £2,137.70 (inc. 1-year licence)
  • Annual cost: £56.63
  • SMS: £0.10 per message
  • Total initial cost: £2,332.35 (inc. 1-year licence)
  • Annual cost: £56.63
  • SMS: £0.10 per message

Note: This option effectively gives two extra sensors at ~50% of the normal price
