https://t.co/F7qf5ngGvL roadmap for April–May 2026 is live.

This spring we're launching a blog on https://t.co/F7qf5ngGvL with environmental reports that matter — dust storms in Cyprus, industrial emissions in Togliatti, air quality on Koh Phangan. Our X account and Telegram bot are getting wired into Roseman so alerts fire automatically when thresholds are breached. By May, Airbnb hosts will be able to prove their apartment's ecology with real sensor graphs.

The Altruist product line is expanding. Insight ships as a standalone indoor sensor, a Repair Kit keeps devices maintainable under $30, and the Family Pack bundles indoor and outdoor coverage. In May we're adding gas sensing (NOx, O3), prototyping a combined Insight+Urban device, and building Insight standalone firmware — a direct Aranet4 competitor targeting Amazon.

On the infrastructure side, https://t.co/F7qf5ngGvL is becoming a federated network. Multi-provider map support arrives in April, and by May both Connectivity and Roseman ship as standalone servers. Communities will be able to fork https://t.co/F7qf5ngGvL and run their own instance.

We're also preparing an Indiegogo campaign — eco-drone adventures in Cyprus, monitoring water quality at beaches and reservoirs.

Perfect morning 🧘‍♀️🌿

After a long abnormal heatwave, I can finally sleep with open windows again and wake up with real fresh air.

Sleep Analytics showed a great microclimate throughout the night:
🟢 CO₂ — fresh air while sleeping
🟢 PM2.5 / PM10 — clean air with low particle levels
🟢 Noise — a calm night without strong noise pollution
🟢 Humidity — comfortable humidity level

Good sleep → fresh air → morning yoga with open windows 🧘‍♀️
Not just “I feel like I slept well.”
Real data about the environment where my body recovers 🌱
Create a space where you feel good.

Do yoga.
Breathe deeply.
And know what you breathe 🌿

Over the last few weeks my iPhone has been warning me about poor air quality!

But global city data doesn't tell me what is happening right outside my window.

My street. My balcony. My home.
Air quality is local.

Create your own monitoring point with Altruist — an open hardware & open-source environmental sensor.

Just install the ready-to-use device and track PM2.5 #PM2_5, #PM10, noise and #ClimateData around you. Expand it with #DIY modules — add sensors for #NO2, #NOx, #O3, #CO, #SO2 and other urban indicators.

Know when to open your windows, when to go for a long walk, and understand what is really happening in your environment.

Your data belongs to you!

🥵 🌡How not to suffocate indoors when it's 40°C outside?

During a heatwave, we keep our windows closed and run air conditioners or air coolers to keep our homes comfortable.

But there's another problem: CO₂ levels indoors keep rising. The air becomes stale, you feel sleepy, tired, and it's harder to concentrate.

💡 Don't leave the windows open longer than necessary.

Monitor your indoor CO₂ levels and ventilate only as long as needed. Your sensor will tell you when the air is fresh again, so you can close the windows before the heat takes over.

🟥 Altruist Urban — monitors outdoor conditions.
🟩 Altruist Insight — tracks indoor air quality and CO₂ levels.

Don't guess. Measure.

We feel that this partnership can become a powerful step toward the positive transformation our island community has been waiting for.

Now #KohPhangan — the island world-famous for its #FullMoonParty, and one that suffers from open waste burning — has enough sensors connected to be included in the hourly analysis by our AI, Nausicaä!

I installed two Altruist Dual kits at home. I connected them to my local open-source Home Assistant smart home server and set up an automation linking an IKEA air purifier to the Urban unit mounted on the veranda. The Insight paired with that veranda Urban went above the living room sofa — the perfect spot for checking CO₂ in the living room, and a place where the e-ink screen won't bother anyone with light, while showing data from both the balcony and the room without getting up from the couch. The second Urban + Insight kit went into the kids' room: the Urban under the desk, so I know how dusty it is where my child plays, and the CO₂ sensor on the desktop.

Only one Urban is published to the https://t.co/bRn9D2rEzj map — the other three devices run in local-only mode. No other devices will grant you such flexibility.

Very happy with the setup. I'd say it's a must-have for any family with a tech geek in it — the whole family ends up interacting with the sensors a little and learning something new.

White haze over Limassol this morning — dust, or just humidity?

The citizen network says humidity:
• coarse (PM10) and fine (PM2.5) dust stayed below the WHO guideline all night and morning
• coarse/fine ratio ≈ 1.9 — mixed marine + urban background, not the >2.5 of a Saharan dust intrusion
• satellite column stayed clear (AOD 0.11–0.17) — no dust aloft

So the milky look is light scattering on hygroscopic sea-salt and background aerosol at ~70% humidity — water, not mineral dust.

Practical: fine to ventilate; the haze burns off as the day warms and humidity drops. No purifier or mask needed today.

"Ein schöner Tag in Schönbrunn with Altruist Urban "🌿
As part of my ongoing urban environmental experiments, I decided to measure the acoustic and climate conditions inside one of Vienna’s most beautiful parks — Schönbrunn.
Since the park is huge, I compared several zones: the Main Entrance, Main Alley, Roman Ruins, Gloriette, Zoo Area, and the evening park atmosphere. And it was an extremely hot day ☀️

Eurovision in Vienna 🇦🇹 meets Altruist Urban 🔊 🎼 // 12.05.2025
I conducted the first daytime noise measurements around Eurovision Village at Rathausplatz in the center of Vienna using the Altruist Urban sensor #AltruistAirQuality @AIRA_Robonomics @RobonomicsHW @SensorsSocial
I was genuinely surprised that despite the massive and noisy festival area, the nearby residential streets remained relatively quiet during the daytime. Vienna is handling this very well! 🤟

Meet @Anna_Wimmer_S — she maintains several sensors in Austria 🇦🇹 as part of the citizen network, and has done some genuinely fun work before: measuring the noise at Hong Kong's bird market 🇭🇰🐦 , and how loud the parties actually get on Koh Phangan 🇹🇭🤟

A series of short video stories about the https://t.co/F7qf5ngGvL project is here — told by the people who've been part of it over the years and tested air quality sensors firsthand.

"The inspiration came from the Luftdaten project, initiated in Stuttgart, Germany, which proved that citizen-driven air quality sensor networks can scale to tens of thousands of participants. The architecture was improved by eliminating bottlenecks like the single centralized server for collecting and distributing sensor data..." - @PaTara43

🟢 Morning · 19 April. The episode is over.

The full timeline of the Limassol dust storm — from the first impact on Thursday evening to clean air this Friday morning — in one chart.

Two waves hit the city overnight. The second, arriving before dawn on Friday, turned out to be the strongest air quality event we have ever recorded in Limassol. By early afternoon it was fading, and by evening the readings were back below the health limit.

A small bump returned around 9 PM as the boundary layer compressed — but it stayed well below the WHO line and resolved by midnight.

This morning the air is clean. Dry-corrected readings are around 12 µg/m³ — back to normal spring levels.

🪟 Windows wide open
🏃 Morning run — perfect
☕ Balcony coffee — enjoy
👶 Safe for everyone

Dust storm has reached Limassol.

Every sensor in our network is above the WHO health limit right now. The entire city crossed the line at once — this is not one device, not an artefact. This is real.

An hour ago the air was calm. Then the front arrived.

The satellite haze coefficient is forecast to more than double through the night. What you see now may not be the peak.

If you are in Limassol tonight: close your windows on the wind-facing side, run your air purifier if you have one, and limit time outdoors until morning.

🟢 Evening update · 19:00 Cy, 18 April.

The storm is behind us.

Our sensor network has been below the WHO limit for six hours straight. Readings settled around 25 µg/m³ and continue to drift down. The satellite haze coefficient dropped from last night's record of 0.96 to 0.27 — nearly back to a clear sky.

The full picture — from first impact to final clearing — in one chart. Two waves, twenty hours, over.

🪟 Open your windows — fresh evening air is back
🏃 Outdoor sport is safe again — go for that run
🍽️ Balcony dinner tonight? Absolutely
👶 Safe for children and sensitive groups
🧹 Good time to air out the rooms that were closed since last night
