Mould Risk Analytics gives you a portfolio-wide view of mould risk conditions across your rental units over time. It surfaces which properties are at elevated or significant risk so you can take action before visible mould develops protecting your property, your guests, and your maintenance budget.
Understanding mould risk levels
Minut calculates mould risk continuously from temperature and humidity data. When certain combinations persist over extended periods, conditions become favourable for mould growth. Risk is classified in three levels:
No risk: Current conditions do not support mould growth
Elevated risk: Conditions are starting to favour mould; monitor closely and consider action
Significant risk: Conditions strongly favour mould growth; investigate and act promptly
Minut detects conditions, not mould itself. Elevated or significant risk means the climate inside the unit is favourable for mould growth and it does not confirm that mould is present. A physical inspection is needed to determine whether mould has actually formed, particularly in areas like windows, behind furniture, or under carpets where local conditions may differ from the room average.
How risk is calculated
Minut looks at the previous seven days of temperature and humidity readings for each device and evaluates mould risk on a weekly cadence, per home - there's no manual "run now" option, and the detection can't be disabled. Because it's based on a rolling week of data, short spikes get smoothed out, and it can take a little while for a change in conditions to be reflected in the risk level.
Alerts and notifications
When a device's risk moves up into elevated or significant, and the home has Indoor climate monitoring enabled, Minut adds a risk alert to the device, records the change on the home timeline, sends a push notification to users who have mould notifications turned on, and emails eligible recipients. If the risk later drops back to no risk, Minut records a cleared event and sends a cleared email - no push notification is sent for clearing. A device that's already alerted doesn't send another notification for further changes at the same level.
If Indoor climate monitoring is turned off for a home, mould risk still gets calculated in the background, but no alerts, timeline events, or notifications are shown or sent until it's turned back on.
What you can see in the analytics view
Risk trend over time: how mould risk levels have changed across your portfolio in the selected period
Units by risk level: a breakdown showing how many units are at no risk, elevated risk, and significant risk
High-risk unit list: the specific properties with elevated or significant conditions, and how long those conditions have persisted, so you can prioritise which to inspect or treat first
Report details and plan availability
The organization-level report includes two views: homes grouped by mould level over time, and a paginated list of homes with elevated mould weeks. Both can be scoped by date range, up to roughly six months at a time.
Some advanced report features - including drill-down on the elevated-risk homes table and filtering by home group - are only available on higher-tier plans. If your plan doesn't include them, you'll see an upgrade prompt instead.
Who can see and manage mould risk information
Organization admins can toggle Indoor climate monitoring for a home, view the analytics report and per-device mould graphs, and receive mould risk push and email notifications when their personal notification setting is on.
Members can view the report and per-device graphs for homes they have access to, and receive notifications as configured - only admins can toggle Indoor climate monitoring.
Responders don't have access to the mould risk analytics report or per-device graphs; response services don't include mould risk dispatch.
Limited or restricted roles don't have access to mould risk surfaces.
Guests never see mould risk information, in the app or in guest communications.

What to do when risk is elevated or significant
Increase temperature: raising room temperature reduces relative humidity, lowering mould risk
Improve ventilation: open windows between stays or ensure the HVAC system is running adequately
Install a dehumidifier: particularly effective for properties in humid climates or with known moisture issues
Inspect the property: check areas most prone to localised mould: around windows, behind sofas, under carpets, in bathrooms
Risk levels change slowly. It may take several weeks after taking action before the risk level drops. This is normal as the sensor is measuring sustained climate conditions, not immediate changes. Keep monitoring and check back after 2–4 weeks.
