Two SHT41, two viewpoints
One probe at the canopy, one outside the tent. Factory-calibrated to +/- 0.2 degrees C and +/- 1.8 percent RH, both sampled at 1 Hz. VPD is computed on the hub.
Pre-launch / waitlist openESP32-C6 / 2 x SHT41 / 4 x PWM / IR learn / Matter 1.3
A Matter-native grow hub for small indoor rooms.
AGS senses inside and outside air, times your fans, dims your light, fires your mini-split, and commissions the Matter plugs for every mains load. Hosted on independent EU infrastructure. Not on AWS, Google, or Azure.

System view
One hub. Two sensors, four PWM channels, one IR blaster, a Matter fabric.
ESP32-C6 at the center. Sensors inside and outside the tent feed PID loops at 1 Hz. PWM drives low-voltage fans and dim lines. An IR blaster speaks to mini-splits and remotes. Matter pairs any Wi-Fi plug for mains loads.

PWM + IR + Matter
Four PWM channels drive low-voltage fans and light dimming lines. An IR blaster learns and fires codes for mini-splits and other remotes. Matter handles every mains load.
Hosted by us, in the EU
We run the AGS cloud on independent EU infrastructure. Not on AWS, Google, or Azure. You plug the hub in. We keep the backend alive.

What's in the hub
Four rails, one product.
The hardware and firmware are locked. These are what ships in release, not aspirations.
One in-tent probe and one outside probe on a TCA9548A multiplexer. Both keep their factory calibration. VPD is computed on the hub from the pair.
LEDC PWM channels on the ESP32-C6. Assign each one in the app: light dim line, sunset ramp, EC/exhaust fan with PID, circulation fan, humidifier trigger.
38 kHz RMT transmit and receive. Learn the codes off your existing AC remote, mini-split, ventilator, or aux light, then fire them from the app.
Pair any Wi-Fi Matter plug directly from the hub. Up to 12 outlets join the same room schedule. No second app, no vendor cloud, no hub hop.
Why two sensors
One probe tracks the canopy. The second tells the hub what the outside air is doing.
A single in-tent sensor only sees microclimate. A second SHT41 outside the tent gives the hub the delta it needs to answer the real question: is it cheaper right now to pull outside air or to dose the humidifier? AGS reads both at 1 Hz and computes VPD from the pair on the hub.
- Temp: +/- 0.2 C typical, -40 to +125 C range (SHT41).
- Humidity: +/- 1.8 percent RH typical, 0-100 percent RH range.
- Both probes ride a TCA9548A I2C mux with factory calibration.
- VPD computed on-device from the pair, not from a single probe.

Outcomes
What changes in the room when AGS is live.
Concrete day-to-day changes, not marketing promises.
A room that reads itself
Two SHT41 probes mean the hub knows the difference between canopy drift and outside pressure. When the outside air is dry and cool, AGS can schedule the exhaust to help. When it is not, the hub stops guessing and doses the humidifier instead.
One appliance, not a kit
A sensor unit, a plug controller, and a climate computer in one hub. No Raspberry Pi, no vendor silo, no chain of apps that pretend to talk to each other.
Your mini-split on the schedule
Most small-grow controllers stop at smart plugs. AGS learns the IR code off your AC remote, stores it on the hub, and fires it on the same schedule as your lights and fans.
A grow journal, not a spreadsheet
Plants, strains, fertilization recipes per stage, weekly reports with photos and climate averages, and a structured harvest log. Built into the same app as the controller.
What AGS replaces
One appliance instead of four half-working tools.
If any of these are in your room today, AGS is the one device that absorbs the job.
Mechanical timers
Stop dosing light and water by wall clock alone. AGS swaps fixed timers for schedules that respond to live VPD, phase, and outside air.
Orphan smart plugs
No more Tuya app for the light, Shelly app for the fan, and manual notes for what is plugged where. Matter plugs commission directly to the hub.
Your AC remote on the counter
AGS learns your mini-split remote and fires it on the same schedule as the rest of the room. The remote goes back in the drawer.
A notebook for grow notes
Strains, fertilization recipes per lifecycle stage, weekly photo and climate reports, harvest wet/dry weights. Captured in the app next to the live room state.
How we compare
Where AGS sits on the small-room shelf.
Without naming names: AGS is built for the space between single-probe sensor pods and commercial-warehouse controllers.
Read-only, no control
Single-probe sensor pods log nice charts but cannot switch a plug, dim a light, or trigger your mini-split. AGS reads, decides, and acts in one appliance.
Only talks to one ecosystem
Controllers from a fan brand only control that fan brand. AGS pairs any Matter Wi-Fi plug and any IR appliance with a remote. You are not locked into one vendor.
Priced and sized for warehouses
Professional grow controllers are built for multi-rack commercial rooms with dedicated HVAC. AGS is sized, priced, and designed for a 1.2 m tent in a spare room.

Trust
Hosted by us, in the EU. Signed OTA. Local-first loops.
What data AGS keeps, where it lives, and what you can verify.
Independent EU infrastructure
AGS runs on an EU provider that is not AWS, not Google, not Azure. Data lives in the EU. GDPR is the default, not a retrofit.
Local-first loops
Sensing, PID, schedules, and PWM act from the hub. If the cloud is offline the room keeps running. The cloud is for visibility, history, and the app - not for keeping the lights on.
Signed OTA with history
Firmware images are signed, downloads are tokenized, and every applied update is timestamped in the app's OTA history. Dual-slot flash means a failed update rolls back on its own.
Next step
One email when units ship. That is the entire newsletter.
