One ESP32-C6 hub. Two Sensirion SHT41 probes on an I2C multiplexer. Four LEDC PWM channels for low-voltage loads. A 38 kHz IR transmit and receive path for real remotes. A Matter 1.3 commissioner for Wi-Fi plugs. A Flutter app over TLS MQTT to an AGS-hosted EU cloud.
Every rail in the stack is already working in engineering samples. This page explains how they fit together.
ESP32-C6 runs PID, schedules, and the Matter commissioner. Sensors sample at 1 Hz. PWM drives low-voltage loads. IR speaks to remotes. Matter pairs any Wi-Fi plug. The cloud is for visibility, not uptime.
One RISC-V hub. Wi-Fi 6 and Bluetooth LE. Four LEDC PWM channels at 13-bit resolution. A 38 kHz RMT IR transmit + receive path for learning real remotes. A Matter 1.3 commissioner that can pair up to 12 Wi-Fi plugs on-network.
Both probes are Sensirion SHT41 at +/- 0.2 degrees C and +/- 1.8 percent RH typical. They ride a TCA9548A I2C multiplexer so they keep the same factory address without a stepdown board. One probe inside the canopy, one outside.
PID loops for light, exhaust, and humidifier run on the ESP32-C6. Schedules layer on top with phase-aware setpoints. The app tunes and inspects; the room never has to wait for a round trip to the cloud.
The shortest honest description of the product.
Place the internal probe at the canopy and the external probe outside the tent. AGS reads both at 1 Hz and computes VPD from the pair.
Low-voltage loads (DC fans, LED dim lines, ramp signals) take PWM directly. Schedules and PID targets run locally. The hub keeps acting if the internet drops.
Commission any Wi-Fi Matter plug for mains loads. Learn the IR codes off any remote you already have. Everything lands in the same app with the same schedule surface.
Sensing, PID, schedules, PWM, and IR all live on the hub firmware. The AGS cloud is for dashboards, history, the grow journal, and cross-device sync. If the internet dies, the room does not.
