If you notice heating, a burnt smell, discolouration, or sparking — switch OFF the main MCB immediately and do not use the device. Then read below before reinstalling anything.
Most common causes
- Exceeding the load rating. Running a high-wattage appliance on a node rated for less current causes heat. Match the appliance to the right device (see ratings below).
- Loose or under-tightened terminals. A loose wire arcs and heats up. Every terminal must be firmly seated on a properly stripped wire.
- Wrong device for the load — e.g. a geyser/AC/motor on a standard node instead of a 16A device.
Respect the load ratings
- Standard smart-switch nodes are for lights, fans and small appliances.
- For high-load appliances (geyser, AC, motor, large socket), use a 16A-rated AZIOT node or smart plug.
- Never gang multiple heavy appliances onto one low-rated node.
If you’re unsure which device suits an appliance, ask us before wiring — it prevents damage and keeps your warranty valid.
What to do next
- Keep the main power OFF to that circuit.
- Take clear photos/video of the device and wiring.
- Start a warranty claim with your invoice. Our team will inspect and advise on repair or replacement.
Safety note: a burnt device is an electrical hazard — don’t attempt to open or repair it yourself.
Frequently asked questions
My AZIOT device is heating up or smells burnt — what should I do?
Switch off the main MCB to that circuit immediately and stop using the device. Take photos/video, keep your invoice, and raise a warranty claim. Don’t open or repair a burnt device yourself — it’s an electrical hazard.
Why did my smart switch burn out?
The usual causes are exceeding the node’s load rating (a high-wattage appliance on a low-rated node), or a loose terminal that arcs and heats. Use a 16A-rated device for heavy appliances and ensure every terminal is firmly tightened.
Which AZIOT device should I use for a geyser or AC?
Use a 16A-rated AZIOT node or smart plug for high-load appliances like geysers, ACs and motors — not a standard node. If unsure, contact support before wiring.
