Overview of the eleven measurements
Carbon Dioxide ppm The breath signal. How fresh is the air you are in? Carbon Monoxide ppm Low-level exposure, tracked over time. Particulate Matter µg/m³ See what you breathe. Down to one micrometre. Temperature & Humidity °C · %RH Comfort is a range, not a number. Barometric Pressure hPa Weather, altitude, storms — all in one number. VOC & IAQ Index index Every gas. Every particle. One honest score. Sound Level dBA The ambient floor, measured — never recorded. Ambient Light lx Your circadian signal, measured.
For your space
All solutions
 Home Kitchens, bedrooms, nurseries, basements. Envora shows you what you breathe — and tells you how to fix it, usually for free. Office & Co-work CO₂ is the single strongest environmental lever on office productivity — and the cheapest to fix. Envora gives facilities teams and founders the number to argue with. CO₂ and indoor air quality monitoring for schools Classroom CO₂ and indoor air quality evidence for better ventilation decisions, measurable cognitive lift, and the data trail governors and parents want. Labs & Clinics Envora One is precise enough for laboratories, clinics and regulated spaces, and comes with a signed calibration certificate per device ID. Studios & Gyms Hot yoga, spin, HIIT and small studios generate extreme humidity and CO₂ loads. Envora tells you how your ventilation is holding up — live, per-room, per-class. Podcasts & Studios Envora flags the HVAC hum, the fridge compressor, the neighbour's drill — and the concentration drift that flattens your delivery — before the tape picks any of it up. Landlords & Letting Continuous, timestamped indoor air quality records for every unit you manage — so damp disputes end in data, not arguments.

Tenant-safe air quality dashboards

A good landlord–tenant relationship around damp and air quality is built on shared data. Envora's tenant-safe access links share what tenants need to see without exposing what they should not.

What tenants see and do not see

Tenant-safe access shows:

- 7-day average humidity per room (not minute-by-minute occupancy patterns)
- Daily mould-risk flag (yes/no)
- Daily ventilation summary (was the property ventilated this 24 hours, yes/no)
- Last 6 months of monthly humidity ranges
- A simple traffic-light status: green / amber / red

Tenant-safe access does NOT show:

- Minute-by-minute readings (which could reveal when the tenant was home)
- Audio readings (which we do not record anyway)
- Sound-level peaks (which could imply occupancy)
- Any other tenant whose property is on the same Fleet account

Why transparency matters

In our experience, the landlords who share air quality summaries with tenants see fewer damp disputes — not more. The shared data:

1. Demonstrates that the landlord is taking the property seriously.
2. Gives tenants actionable information (ventilate more in the bathroom, dry laundry on the line not on radiators).
3. Builds a documented record both sides can refer to.
4. Reduces the likelihood of a complaint escalating to the Ombudsman or Tribunal.

Landlords who choose NOT to share access remain fully able to use the data internally — tenant-safe links are an option, not a requirement.

FAQ

FAQ — Tenant-safe air quality dashboards

How does the tenant access the dashboard?
A unique secure link sent by email. No password required, link can be revoked at any time. Mobile-friendly.

Can I customise what the tenant sees?
Yes — at Fleet Team and above, you can choose which channels and which summary windows the tenant-safe view shows.

Do tenants get alerts?
Optional. Some landlords enable mould-risk alerts to tenants (which prompts ventilation behaviour); others keep alerts landlord-only.

Are tenant-safe links available on Fleet Starter?
Yes — tenant-safe link generation is included from Fleet Starter (£3/device/month, £15/month minimum) upward.
