Immediate availability for real projects - not long waits
When a retrofit, class lab build or client tender needs parts this month, lead time beats list-price every time. Communica holds local stock of controllers, sensors, relays and accessories so you can finalise designs, collect same day from Samrand or a branch, and issue VAT invoices or account quotes without import delays.
Why local stock matters for South African makers and installers
Local availability reduces downtime and keeps project cashflow healthy. Instead of waiting weeks for overseas shipping, choose devices and modules that are physically on the shelf in Samrand or our Pretoria and Cape Town branches. You can verify inventory live, plan pickup, and get hands-on support for compatibility questions.
What we typically have in stock
- Smart controllers and gateways (Wi-Fi, Zigbee, Z-Wave compatible models)
- Relay modules, DIN rail power supplies and smart meters
- Sensors: motion, door/window, temperature, humidity and water leak
- Maker boards and peripherals (Raspberry Pi, Adafruit accessories)
- Tools, enclosures and cabling for installation and prototyping
Specification quick-check: pick what fits
Before you order, verify three quick specs: power (voltage/current), I/O count (relays, binary inputs, analog inputs) and network protocol. That ensures your new module plugs into existing panels or software without surprises.
| Item | Key spec | When to choose |
|---|---|---|
| Wi-Fi gateway | 2.4 GHz, MQTT support | For cloud or local MQTT automation servers |
| Zigbee coordinator | USB or DIN form, channel compatibility | When using battery sensors and mesh routing |
| 16A relay module | AC switching, 16 A per channel | For lighting or resistive loads |
Compatibility tip - mix-tested approaches that work locally
Pairing a local Zigbee coordinator with popular brands such as Aeotec sensors or widely compatible actuator modules reduces integration risk. For maker projects, Raspberry Pi combined with Adafruit HATs gives the fastest route from prototype to classroom demo.
