IoT Devices

Hardware we design ourselves, ready to connect

Controllers and meters built by the Invisor team, from circuit board to firmware. They work with FarmBoss and Power Management out of the box — or with your own system over MQTT / Modbus.

Keeps working offline

Rules, schedules and the clock run on the device itself.

OTA firmware updates

New features and fixes without a site visit.

Open standards

RS485 Modbus and MQTT work with other sensors and systems.

One team, end to end

Designed, installed and maintained by Invisor engineers.

Smart Farm

FARM Manager — Smart greenhouse controller

Smart greenhouse controller

FARM Manager

A wall-mounted greenhouse controller in a metal enclosure. It drives water valves and greenhouse equipment from RS485 sensor readings, with automation rules that keep running when the internet drops.

  • 4 solenoid-valve outputs
  • 6 external-relay outputs: fan, fog, light, pump, water, fertilizer
  • Rules on temperature, humidity, light, VPD, CO₂, soil moisture and time
  • Accepts on-site push buttons and a mode selector switch

Irrigation / fertigation controller

Irrigation Controller

Controls water and fertilizer valves by zone, plus the pump and water source. Water for a set time from the app, or let soil moisture decide.

  • 4 water zones + 4 fertilizer zones
  • Opens the water source and pump automatically, with a pump start delay
  • Caps watering based on soil moisture
  • Per-zone, timed watering from FarmBoss

Automatic nutrient mixer

Fertilizer Mixer

Continuously measures EC and pH in the mixing tank and doses A/B nutrients and pH-down automatically. Built for hydroponics and fertigation.

  • Doses A+B when EC drops below setpoint, then waits to mix before re-measuring
  • Applies pH-down only after repeated confirmation — no overdosing on noisy readings
  • Always corrects pH before adding nutrients
  • Monitors water flow and water temperature

On-farm weather station

Weather Station

Measures wind, rain, temperature, humidity, light and dust where your crops actually are — for decisions and as triggers for automation. Solar-battery ready.

  • 8-point wind direction, wind speed and daily rainfall
  • Temperature, humidity, light, PM2.5 / PM10, CO₂, O₃
  • Solar battery voltage and charge monitoring
  • Feeds FarmBoss and can trigger automation rules

Air-conditioner controller

AC Controller (IVS‑ACMS)

Fitted to each room's air conditioner. Switch power, set temperature, mode and fan through the unit's control port or infrared, linked to the gateway over LoRa — no signal cabling.

  • Controls via the AC's port, or IR with 250 learnable commands
  • Room temperature / humidity sensor
  • One gateway handles up to 50 rooms
  • On-device schedules and thermostat; SD-card buffering when offline

Circuit-level power meter

Power Meter

A CT current node that clamps onto circuits in the panel and reports over RS485 Modbus into Power Management. The gateway also reads 3-phase Modbus meters on the main board.

  • 30 A split-core CT — no wires cut
  • RS485 Modbus RTU, many nodes on one bus
  • Reads 3-phase Modbus meters (e.g. Schneider PM2230) via the gateway
  • Data lands on the Power Management dashboard immediately
