The short answer
Start with the biggest users: the geyser and the pool pump, then lighting and standby loads. Automation helps most when it switches large loads off at the right time. Anything wired into the mains, such as a geyser, should be installed by a qualified electrician.
| Item | Typical impact | What automation does |
|---|---|---|
| Geyser | Often one of the biggest household users | Heats at set times and switches off when it is not needed |
| Pool pump | Medium to high, depending on the pump | Runs on a schedule you choose |
| Lighting | Low to medium | Switches off in empty rooms and dims |
| Standby loads | Low, but constant | Cuts power to TVs and chargers at night |
| Monitoring | Helps you see the rest | Shows what each circuit uses |
Impact depends on your home, so measure before you spend.
A timer or smart controller can limit when the geyser heats. Switching mains-level loads is electrical work, so ask a qualified electrician to fit it. A geyser blanket also cuts heat loss, with or without automation.
Many pumps run longer than needed. A schedule can match run time to the season and your water. Ask your pool company what run time suits your pool.
LED bulbs already cut lighting use. Smart switches and sensors stop lights staying on in empty rooms. See why smart lights go offline before you choose bulbs.
Seeing consumption by circuit shows where your electricity goes. It also helps if you have solar or a backup battery, where timing matters.
Automation that depends on the internet stops when the router does. Read keeping a smart home working during load shedding.
Usually the geyser, because heating water is often a big share of a home’s use.
They can help by cutting standby loads, but the plug itself uses a little power.
It can. Timing loads around solar production and battery use is a common goal.
For anything wired into the mains, yes.
