Systems and design facilitating remotely controlling an imitation candle device

An imitation candle device that can be controlled remotely, comprising:

• a flame element shaped to resemble a candle flame and protruding from top of the imitation candle device;
• a body including an installation cavity;
• one or more light sources operably configured in the body;
• an electronic circuitry coupled to the one or more light sources to control lighting of the one or more light sources;
• and
• an electronic module, configured to be installed in the installation cavity, that couples with the electronic circuitry to facilitate remote control of the imitation candle device,
• wherein the installation cavity comprises:
• a first subspace extending between a first surface and an opening, wherein the first surface includes a rectangular subsection to accept an insertion interface of the electronic module to form a connection with a communication interface of the imitation candle device and the opening allows insertion or ejection of the electronic module, the first subspace further bounded by a side wall;
• a second subspace extending between a second surface to the opening, wherein the second surface is recessed and is situated at a first distance from the opening, and the side wall includes a groove that runs from the second surface at least partially down the side wall toward the first surface;
• and
• a third subspace extending between a third surface and the opening, wherein the third surface is recessed and is situated at a second distance that is greater than the first distance from the opening.
