Lift Logic Systems delivers real-time environmental monitoring, hardware orchestration, and precision scheduling for controlled-environment agriculture — from the cloud down to the RS-485 bus.
Lift Logic Systems is a precision industrial automation platform for controlled-environment grow facilities. It connects browser-based operator dashboards to physical hardware in near-real-time via RS-485/Modbus serial buses running on a Raspberry Pi edge controller.
Operators monitor and control every subsystem in a grow center — lighting, climate, irrigation, CO₂, fans, and motorized table lifts — from a single Mission Control interface. The technology is domain-agnostic and applies to any controlled-environment automation scenario.
Live temperature, humidity, CO₂, and soil moisture readings polled continuously from RS-485 sensor networks. Alerting fires when readings breach configurable thresholds.
Direct command and control of LED PSUs, stepper motor drivers, and Waveshare 8-channel relay boards over dedicated RS-485 serial buses. No middleware, no delays.
Per-room light and environment schedules execute automatically. Operators see every scheduled event, manual override, and admin action on a full event calendar.
Per-room and global alert thresholds for every sensor type. Email notifications dispatched when conditions exceed safe operating ranges, with full audit logging.
Eight purpose-built control domains covering the full lifecycle of a precision grow environment.
The primary operator landing page. Room cards show live temperature, humidity, CO₂, alert badges, table counts, and sensor status at a glance. Clicking a room updates the full overview panel in-place.
Gauge cards for temperature, humidity, CO₂ PPM, and soil moisture — each with healthy/warning/critical status chips and system summary tiles for lifts, lights, fans, and irrigation.
Motorized grow table lifts driven by DM556RS stepper motor drivers over RS-485. Each table has a unique Modbus slave ID. Raise, lower, or position tables with precision from the operator dashboard.
Multi-channel LED PSU control (white, blue, far-red, deep-red) via Modbus. Current-based amperage control per channel. Instant manual overrides or automated schedule execution per room.
Per-room lighting and environment schedules run automatically via APScheduler. Light cycles, fan rotations, and irrigation sequences are all configurable with start times, durations, and repeat intervals.
Continuous RS-485 polling of Taidacent SHT30 temperature/humidity sensors, CO₂ sensors, and soil moisture probes. Readings cached and served to the dashboard in near real-time.
Configurable per-room and global thresholds per sensor type. Alert emails dispatched via Postmark when conditions breach safe ranges. Full alert feed visible on Mission Control.
Dedicated RS-485 serial buses for lights, sensors, lift motors, and environment relays — each independently configured for baud rate and parity. Scales to any number of buses required by the installation. Low-level Modbus RTU via pymodbus 3.5.
A cloud-to-edge stack engineered for secure, low-latency hardware control without exposing any device to the public internet.

The Raspberry Pi has no open ports. All operator traffic routes through Tailscale's encrypted mesh — the Pi is invisible to the public internet. You own your hardware and your data.
Each bus is independently configured — scale up or down to match any installation:
| Lights | 115200 8E1 — LED PSU / Modbus |
| Sensors | 19200 8N1 — Temp / Humidity / CO₂ / Soil |
| Stepper | 38400 8N1 — DM556RS table lift motors |
| Env | 9600 8N1 — Waveshare relay boards |
One installation manages multiple independently-configured grow rooms, each with its own sensor network, relay devices, LED channels, and lift tables. Rooms are isolated in configuration but visible together on Mission Control.
The same hardware and software platform applies beyond grow facilities — pharmaceutical cleanrooms, aquaculture systems, environmental test chambers, and any controlled-environment automation scenario.
