Firmware & Control Algorithms Designed with Expert Scientific Guidance

Every control loop, stage setpoint, ramp algorithm, CO₂ threshold, humidity curve, and temperature regime in this firmware was designed in direct consultation with over 50 PhD-holding scientists and researchers specializing in mushroom mycelium biology, substrate physiology, environmental cultivation science, and commercial fungiculture. The logic is not guesswork — it reflects decades of peer-reviewed laboratory and field research, translated into real-time embedded automation code.

Firmware Architecture

Five Layers. One Control System.

The firmware is structured in discrete functional layers — each independently tunable, each communicating through a defined register interface.

Contol-X firmware architecture — 6 layers: sensor acquisition, ramp engine, control loop, stage engine, cloud sync, HMI interface
01
📡
Sensor Acquisition Layer
Continuously reads all 7 sensors on configurable intervals. Handles NTC probe thermistor linearization, CO₂ NDIR conversion, and RH capacitive sensing. All values stored in holding registers at 10x precision for integer Modbus compatibility.
02
🔄
Ramp Engine
When a stage transition occurs or a setpoint is changed, the ramp engine intercepts and gradually transitions the effective setpoint at a user-configured rate (ppm/hr, %/hr, °C/hr). The control loop follows the effective value, not the target — eliminating shock transitions for sensitive mycelium.
03
⚙️
Control Loop
Bang-bang controllers with independent configurable hysteresis for each relay. Temperature control reads from the user-selected probe (room, bag core, average, or any individual sensor). CO₂ and RH follow their respective stage setpoints — or ramped effective values.
04
🌱
Stage Engine
Manages 5 standard stages (Manual, Spawning, Casing, Fruiting, Harvest) plus up to 8 named custom recipe stages. Tracks elapsed days, evaluates auto-advance conditions, and applies the next stage setpoints through the ramp engine when stage transitions occur.
05
☁️
Cloud Sync & Command Layer
Pushes live register data to the cloud CRM on a configurable interval. Polls for pending commands from the web panel (setpoints, stage changes, emergency, ramp parameters, recipe uploads). Commands are validated, applied to registers, and acknowledged with HTTP status codes.
06
📺
HMI Interface Layer
Drives the panel HMI display with parsed screen templates. Processes button events from the operator interface. All HMI inputs translate to register writes — no separate code path. Supports panel lock/unlock, field calibration, supervisor messaging, and OTA trigger.
Firmware Capabilities

What the Firmware Does

A complete list of every controllable behavior built into the grow room firmware — from sensor calibration to recipe management to OTA updates.

Modbus RTU Register InterfaceFull 450+ register map covering every sensor, setpoint, control flag, stage variable, and recipe slot — readable and writable by any Modbus master
Gradual Ramp TransitionsCO₂, RH, and temperature setpoints ramp gradually between stages at user-defined rates — no abrupt environmental shocks to the mycelium
5-Probe Temperature ArchitectureFive individually calibrated NTC probes with roles: room air (control), bag core (metabolic monitoring), ambient (reference), panel (equipment protection), spare (custom use)
Selectable Control ProbeChoose which temperature probe drives heating and cooling relay logic: room air, bag core, average of all active probes, or any individual probe by register write
Stage Auto-AdvanceConfigurable elapsed-day trigger per stage. When the stage duration expires, the firmware automatically transitions to the next stage and begins ramping all setpoints
8-Slot Custom Recipe SystemUpload up to 8 fully named custom cultivation stages, each with independent CO₂, RH, temperature, and duration settings. Load any recipe from cloud or HMI
Field Sensor CalibrationNTC probe calibration via known-reference temperature input. CO₂ and RH offset calibration. All calibration values stored in non-volatile memory and persist across power cycles
Emergency StopImmediate all-relay cutoff via register write, HMI button, or physical panel button. Emergency state persists in non-volatile memory — intentional clear required before restart
Panel Lock & Supervisor UnlockNumeric PIN protection for HMI setpoint changes. Supervisor unlock code is network-tied — changes with each device session for security
Over-The-Air Firmware UpdateOTA update triggerable from HMI panel or cloud command. Controller downloads and applies new firmware without physical access — zero downtime production updates
Simulation ModeToggle sensor simulation mode for testing and commissioning — the firmware runs the full control loop with synthetic sensor values, validating stage logic without physical installation
Supervisor MessagingHMI operator can compose and send a text message directly to the grow room owner via WhatsApp from the panel — without phone access
Stage Day CorrectionManually adjust the elapsed day counter for any stage — compensate for power outages, planned holds, or schedule adjustments without restarting the grow cycle
Non-Volatile State PersistenceAll setpoints, stage, calibration values, recipe slots, and control flags are saved to flash memory. Full state restoration after power failure — no manual re-entry required
Network & Cloud Health MonitoringLAN connectivity, internet reachability, and cloud push success status are stored in registers and displayed on HMI — operators can see if the system is reporting correctly
