Searching for an “automatic geyser switch” turns up mostly WiFi controllers for electric geysers — smart plugs and app-controlled switches that schedule when an electric geyser’s heating element runs. If you have a gas geyser, that’s not the product you need, and installing an electric geyser switch won’t solve a gas pilot light problem.
Automatic Switch for Electric Geysers
These connect to an electric geyser’s power supply and let you schedule heating times or turn it on/off remotely via an app, mainly to reduce standby electricity use. They do nothing for gas ignition, since electric geysers have no pilot light to begin with.
Automatic Ignition System for Gas Geysers
This is a different category entirely — it connects to your gas geyser’s existing pilot and thermostat assembly and automatically restarts ignition when gas supply returns after an interruption. If your actual problem is a pilot light going out from load shedding, this is the category you need, not a WiFi electric switch.
How to Know Which One You Need
If your geyser runs on gas and has a pilot light, you need a gas ignition system. If your geyser runs on electricity with no flame involved, a WiFi electric switch is the right category — but it solves a different problem (energy scheduling, not relighting).
Frequently Asked Questions
Is an "automatic geyser switch" the same for gas and electric geysers?
No — for electric geysers, it's a WiFi-controlled power switch for scheduling. For gas geysers, what you actually need is an automatic ignition system that restarts the pilot light, which is a different product category entirely.
I have a gas geyser — will an electric geyser WiFi switch help with my pilot light going out?
No — a WiFi switch controls electrical power and has no way to interact with a gas pilot flame. It won't solve pilot relighting after load shedding.
What should I search for if I have a gas geyser with a pilot light that keeps going out?
Look specifically for a "gas geyser auto ignition kit" or "automatic gas geyser ignition system" rather than a general "automatic geyser switch," since that broader term is dominated by electric-geyser products.
