In facilities exposed to extreme weather conditions, mould can be difficult to control and costly to remediate once established. Because mould thrives in environments where moisture condenses on internal surfaces, prevention is far more effective than treatment after growth has occurred.

Blyx is designed to help facilities understand and manage the environmental conditions that lead to mould, with a particular focus on dew point control. Mould does not grow simply because the air is humid; it develops when room surfaces fall below the dew point of the air, allowing moisture to condense. This invisible surface moisture creates the ideal environment for mould spores to activate and spread.

Blyx does not only regulate temperature — it manages the relationship between temperature and humidity. By continuously monitoring both, the system can calculate the dew point in real time and automatically adjust air-conditioning operation to prevent internal surfaces from dropping below this threshold. This removes the root cause of mould formation by preventing condensation, rather than reacting once visible growth has already occurred.

Each Blyx Environment Controller monitors temperature and relative humidity at five-minute intervals, 24 hours a day. Over time, this creates a detailed profile of normal room behaviour, taking into account external weather conditions and typical occupancy patterns. When combined with reservation data and real-time human presence detection, the platform can determine whether a room is occupied, expected to be occupied, or vacant, and apply the most appropriate environmental control strategy.

This intelligence allows Blyx to identify conditions that may indicate emerging issues, such as:

• Prolonged high humidity when a room is unoccupied
• Over-cooling that may drive surfaces below the dew point
• Abnormal moisture patterns that could indicate ventilation or extraction faults

For example, poorly performing bathroom extraction fans can allow moisture to accumulate, significantly increasing mould risk. By analysing humidity decay rates after shower use and comparing them to normal room behaviour, Blyx can flag potential ventilation issues for maintenance attention before mould develops.

In addition to temperature and humidity, the Environment Controller also monitors light levels at the same five-minute intervals. This data can support:

• Assessment of blackout performance for night-shift accommodation
• Detection of lights left on in vacant rooms, contributing to energy waste

The controller also supports optional expansion modules, including:

• Human presence detection
• Infrared control for air-conditioning and televisions
• Acoustic monitoring
• Air quality sensing, including CO₂, VOCs, and selected chemical fumes

Together, these capabilities allow Blyx to build a comprehensive digital model of each room’s environmental behaviour. This not only improves guest comfort and safety, but enables early identification of abnormal conditions, proactive maintenance, and automated control strategies that reduce both operational risk and long-term asset degradation.

By turning continuous room data into actionable insight and automated response, Blyx helps facilities move from reactive mould treatment to proactive dew point and moisture management — preventing the conditions that allow mould to form in the first place.
