This apartment has been monitored since 5 May 2026. The record covers 84.5% of the hours since then — every interruption is listed further down, none of them averaged away. The readings behind that statement are shown below.
Air temperature, relative humidity, carbon dioxide, PM2.5 and PM10 — sampled continuously by battery-powered wireless indoor monitors, with no client Wi-Fi and no camera or microphone in the apartment.
| Parameter | Averaging window | Limit | Highest observed | Result |
|---|---|---|---|---|
| CO₂ | 8-hour average | 800 ppm | 568.9 ppm | within limit |
| PM2.5 | 24-hour average | 35 µg/m³ | 44.6 µg/m³ | 3 episodes · 58 h above |
| PM2.5 | 1-hour average | 100 µg/m³ | 67.0 µg/m³ | within limit |
| PM10 | 24-hour average | 150 µg/m³ | 52.5 µg/m³ | within limit |
| PM10 | 8-hour average | 100 µg/m³ | 64.1 µg/m³ | within limit |
An episode is a continuous stretch during which the rolling average stayed above the limit. Rolling windows overlap, so we count episodes and the hours they cover rather than the number of windows — the latter would inflate a single long stretch into dozens of separate-looking events.
| Parameter | Comfort range | Observed range | Hours inside range |
|---|---|---|---|
| Air temperature | 22.5–25.5 °C | 22.6–26.1 °C (mean 24.1) | 99.9% · 1 h outside |
| Relative humidity | 20–60% | 33.5–59.2% (mean 45.5) | 100% |
A monitoring record is only worth what its gaps admit. This installation lost 412 hours across 9 interruptions, the longest of them in summer. We publish the gaps rather than average them away: on a client installation a loss of signal raises an alert, and the reason for each interruption is recorded in that home's service log.

That an apartment has been continuously monitored since a stated date, and that the readings behind that statement are available. It is a record of measurement, not a verdict on the property.
No. We do not certify buildings and we are not an accredited inspection body. Certification is issued by accredited bodies; what we publish is the measurement record we are responsible for.
This particular page is our own reference installation in Dubai, published as a working example. A client page carries no address, no names and no personal data — the apartment is identified only by a code the owner controls, and sharing the link is the owner's decision.
Because a record that never shows an exceedance is a record you should distrust. Short episodes above a limit are normal in occupied homes; what matters is that they are visible, dated and bounded.
