For growers & installers
Everything from how it watches your plants to what happens when something goes wrong.
The simple version
No technical knowledge needed. Here's how xGreen fits into your daily routine as a grower.
Sensors measure air temperature, humidity, and soil conditions continuously. You see all of this live on your phone — no need to visit the greenhouse just to check.
Too hot? Too dry? xGreen opens a window, starts the irrigation, or turns on a fan — all without you lifting a finger. You set the rules once, it handles the rest.

Under the hood
xGreen combines an ESP32-S3 microcontroller with industry-standard RS485 wiring, Modbus RTU sensor communication, and a cloud-connected web dashboard.
Atmospheric and soil sensors communicate over the RS485 bus using the Modbus RTU protocol — robust, noise-immune, and capable of spanning 1,200 m.
Eight independently controlled relay channels drive ventilation, irrigation, pumps, and any other 12–230V actuator. Each channel is configurable as automatic or manual.
Eight optoisolated digital inputs connect rain sensors, float switches, limit switches, or manual override buttons. Critical inputs engage hardware failsafes.
Connectivity
RS485 is the backbone of industrial sensor networks. Two-wire differential signalling makes it immune to electrical noise from motors and pumps — exactly the environment found in greenhouses. xGreen polls sensors every second and streams telemetry to the dashboard in real time.
Control
Every relay channel is independently controllable — by an automation rule, a daily schedule, or manual override from the dashboard. Hardware interlocks from digital inputs can block a channel regardless of software state.
Safety
Optoisolated digital inputs sit at the boundary between the safe 3.3 V microcontroller world and field-level voltages. When a critical input triggers — a float switch, rain sensor, or limit switch — the xGreen Core engages a hardware fallback that no software rule can override.
Automation
Automation logic runs directly on the xGreen Core — not in the cloud. Connectivity outages don't stop your greenhouse. Rules evaluate sensor readings against thresholds; schedules fire channels on a clock. Both can be created and edited live from the dashboard.
Scalability
Adding a new greenhouse is as simple as installing another controller and registering it in the dashboard. Sensors and relay expansion boards connect to the existing RS485 bus — no rewiring, no configuration migrations.
