Deployment Scenarios
The Growbud Controller fits into your operation three ways: fully wireless alongside your Growbud sensors, gateway-free over Amazon Sidewalk, or hardwired into your building management system. The RS-485 port does one job at a time: Modbus master to your industrial sensors in wireless deployments, or the building-system connection in wired ones, with nearby Growbud sensors picked up over Bluetooth. Every configuration drives up to four valve zones, 24 VAC or latching DC, with one drive mode per unit, never mixed. The valve counts below are just sample setups.
Wireless: LoRaWAN
Deploy the Controller exactly like your Dro and Vero sensors. Controller and sensors all join the same Growbud gateway. Shown here driving four 24 VAC valve zones on the irrigation manifold.
- • Controller + Dro/Vero sensors on one LoRaWAN network
- • Sample config: 4 AC valve zones on one 24 VAC supply
- • Wire RS-485 Modbus sensors (EC, pH, flow) straight in
- • Miles of range; on-board schedules if the network drops
Amazon Sidewalk
No gateway at all: the Controller joins the Amazon Sidewalk network already blanketing your neighborhood. Sensors connect to the Controller over Bluetooth, shown here running two latching DC valve zones on simple USB-C power.
- • Straight onto Sidewalk: no gateway, no WiFi setup
- • Sample config: 2 DC valve zones (up to 4) on USB-C or 12 VDC
- • Nearby sensors connect over Bluetooth
- • Firmware update only; no new hardware
Building Automation: BACnet
Wire the RS-485 port into your BMS as a BACnet MS/TP node. The Leak port watches the floor, a dry-contact power relay stands ready to shut the pump down, and air-quality monitors report in alongside, all surfaced to the building system as BACnet objects.
- • BACnet MS/TP on RS-485 (BACnet/IP via gateway)
- • Dedicated leak probe input on the Leak port
- • Valve output drives a dry-contact relay for pump shutoff
- • Air quality, leak, and power control in one node
Connector Pinouts
Every port on the Growbud Controller uses standard M12 and M8 A-coded connectors. Hover or tap a contact on the face view to see its signal, or use standard IEC-colour cordsets and match by conductor colour.
M12 A-coded input · separate DC and floating AC pairs
Power input
| Pin | Wire | Signal | Function |
|---|---|---|---|
| 1 | Brown | VDC_IN | 9–16 VDC input |
| 2 | White | GND | DC return / circuit ground |
| 3 | Blue | VAC_HOT | 20–26 VAC RMS input |
| 4 | Black | VAC_RETURN | Floating AC return; not DC ground |
| 5 | Grey | SHIELD | Shield drain tied to controller GND |
- IEC blue normally means 0 V. On the Power connector it does not — contact 3 is 24 VAC hot. Never treat the blue conductor here as a return.
- Never bond contact 4 to contact 2 in the cable; the AC input is differential.
- Use either the DC pair (1/2) or the AC pair (3/4), not both supplies at once.
Conductor colours follow IEC 60947-5-2 for standard A-coded cordsets. Full wiring detail, register maps, and installation procedures are in the Growbud Controller manual.
