Why Altruist Urban

Years of environmental monitoring experience shaped a device built to help you understand the real conditions around your home — not generalized city averages.

Urban is an outdoor environmental sensor designed to help you understand the air, noise, and climate around your home and neighborhood.

Air quality, noise, temperature, and humidity can change dramatically from one street to another. Wind direction, nearby traffic, construction activity, elevation, trees, building density, floor height, and even the orientation of your windows all shape the environment around your home.

That is why generalized air-quality maps often fail to represent what you actually breathe.

Most public environmental maps rely on a limited number of monitoring stations — often placed near major roads or in completely different parts of the city. Even community-driven maps can reflect conditions far away from your neighborhood.

Urban measures the environment where you actually live.

It tracks dust pollution, urban noise, temperature, humidity, and atmospheric pressure in real time — helping you understand your local microclimate and make better decisions about ventilation, comfort, sleep, and everyday wellbeing.

And for advanced users, Urban integrates directly with Home Assistant and local smart-home systems — enabling automations based on real environmental conditions around your home.
