Unifying Water Tanks, Hybrid Solar, Smart Lighting & Perimeter AI in One Nairobi Home

Most Nairobi homes suffer from unexpected dry taps, burnt-out booster pumps, and noisy camera false alarms. Here is how we brought industrial sensor reliability to residential living—controlled from a single phone app with zero cloud subscriptions.

01 / The Everyday Frustrations of Large Nairobi Homes

Empty Roof Tanks, Burnt Pumps & 5 Separate Phone Apps

Homeowners in Nairobi often discover that city council or borehole water stopped flowing only when the taps run completely dry—and by then, the transfer pump has been running dry and overheating.

Meanwhile, solar inverters, gate intercoms, CCTV cameras, and garden sprinklers each live on separate, clunky apps that stop working whenever internet connectivity fluctuates.

02 / What We Installed & Automated

Four Systems Working Together Locally

Ultrasonic Water Tank & Pump Automation

Weatherproof ultrasonic sensors inside both underground and roof tanks monitor exact water levels, automatically transferring water when solar power peaks and shutting off pumps before dry-run damage.

HYXIPOWER Hybrid Solar Integration

Live battery state-of-charge (SoC) and KPLC grid status trigger automatic load-shedding of heavy appliances (water heaters, pool pumps) during night-time blackouts.

Smart Lighting, Gate & Lawn Irrigation

Driveway and perimeter lights come on automatically at sunset. Garden sprinklers check soil moisture and local rain forecasts before watering the lawn.

Human-Only AI Perimeter Cameras

AI smart cameras along the boundary wall ignore dogs, swaying branches, and rain—flashing perimeter floodlights and sending a WhatsApp snapshot only when a person approaches the fence.

03 / Results for the Homeowner

Complete Peace of Mind—Even Offline

  • Never Surprised by Empty Tanks: Instant phone notification if underground reserve drops below 25%, so a water bowser or council valve check happens days before taps run dry.
  • 100% Local Hub Operation: All automations run on a local hub inside the home—wall switches, pump safety cutoffs, and security triggers work even if fibre internet is down.
