Every zone on your phone

NEXP CON is the controller we designed for greenhouses. Put one in each zone and the nexp Greenhouse app shows its temperature, humidity, soil and light as they change. Rules run the fans, pumps and heaters, and you can take over from your phone at any time.

How it works

From a wired zone to your phone

We built the controller and the Greenhouse app together, so there is no integration work between the two.

  1. STEP 01

    Wire the zone

    Fit one NEXP CON per zone on 24 V. Valves, fans and pumps go on its outputs, the heater on its two-key relay and the sensors on their ports.

  2. STEP 02

    Scan to join

    Scan the code on the controller with the nexp app. It joins your organisation over LTE, so there is no Wi-Fi to set up in the greenhouse.

  3. STEP 03

    Sensors appear

    Connected sensors and switches show up by themselves. Misting valves, pressure pumps and other equipment are added from the app.

  4. STEP 04

    Watch it live

    Temperature, humidity, soil moisture and light for every zone, as they change. Tap a reading to see its history.

  5. STEP 05

    Let it run itself

    Rules and schedules handle the routine. Group them into profiles like Summer or Seedlings and switch a whole profile at once.

  6. STEP 06

    Know when it matters

    You get an alert when a zone goes out of range, and you can switch a fan, pump or heater from wherever you are.

The controller

Inside NEXP CON

Designed in-house for greenhouse zones. Pick a number to see what each part does.

NEXP CON greenhouse zone controller — a 24 V board with a Raspberry Pi compute module, LTE and GNSS, battery backup and switched outputs

NEXP CON · REV C · 24 V DC · TAP A NUMBER

  • No Wi-Fi in the greenhouse

    The controller reports over LTE, so it works in a field as well as next to the office.

  • Keeps reporting in a power cut

    Battery backup lets it tell you the power has gone and shut down cleanly.

  • A heater can't turn on by accident

    The heater relay needs two separate signals before it switches.

  • Made for the Greenhouse app

    Zones, readings, rules and alerts are ready the moment the controller joins.

Full specifications are on the circuit design page.
