It appears that there was a short circuit. The Sonoff Basic has an internal fuse which is a one-time trip.

The fuse is soldered in. Replacement requires soldering. Do not try to replace with a wire!  
BASIC R4 does not require a capacitor as it has a full power supply. Therefore it is also suitable for controlling e.g. heating appliances. The use of a capacitor is unnecessary.  
The lamps you show in the picture are cheap so are unlikely to contain a voltage converter or any reasonable power supply stage. They can make quite a mess.

I have several BASIC devices. Nothing like this has happened with any of them for many months. It is difficult to say what happened to your device. It could have been a coincidence. Fortunately it is not an expensive device. Get a new one. Check the installation thoroughly before connecting it, and ensure that the ends of the wires are properly worked (e.g. tinned).

Are you referring to the eWeLink Remote Control or the Magic Switch function?
