Think some may not have battery, it run with capacitor.

Sometime the damage could be due to spike or lighting surged.

Look like is time to change.

This should help.

Is very straightforward, you can control 2 equipments making both flip flop.

All go out must come back. When you have Live, you need neutral to have a complete circuit.

Usually light switch is on with Live, and neutral are all loop neat the equipments. Only A/C, heater, oven switch, or high current switch have both neutral and Live.

If your switch point have A/C or water heater switch, you can tap from there.

Than you need to tap it from the nearest A/C socket, or pull one over.

Live is on the light switch.

Very dangerous to tell people wrong information. They may think is not live and touch the wires.

Electrical shop.

Nope, the shop selling cables, conduit, and major electrical wiring.

One at SS2, the near swensen's ice cream , few more at sea park, near the O&S Restaurant. Or pasar road.

E711 last year price was around 80 to 90.

Std switch don't have neutral line. Most timer require Live + neutral to run.

Most electrical shop selling wiring switches do carry Hager

EH711 can install in db. If you need it to drive higher current equipments u need to install a relay.

Lights is small current, no issue. You need to check if your outdoor light does it seperate from others lighting circuit. Most house will share one circuit for all lighting, or maybe two circuit for entire house lighting. If is share you won't be able to control it from DB.
