Abstract— Energy consumption apart from the use of low-
power consumption devices, it is also necessary to use energy-
saving behavior that supports sustainable energy. Unwise use of

electricity will of course have an impact on the high use of
electricity, this also affects the depletion of electrical energy
supplies because the need for electrical energy is greater than the
supply of electrical energy, for that it is hoped that every
community understands the efforts to use electricity wisely.
Problems faced by households in managing the use of electrical
energy include: Not using LED lights (Light Emitting Diodes);
Using unnecessary electronic equipment; It is not wise to use
equipment that requires electrical energy. The purpose of this
research, among others, is how to monitor the use of electrical
energy in the household by utilizing IoT and connected to the
Android application to make monitoring easier. The contribution
given by the researcher is how to combine microcontroller
hardware, internet and android applications so that they can
support the use of smart homes at home. Research Methodology
includes data collection, needs analysis, program development,
tool design, testing. Conclusions that can be drawn based on
research that has been done include: Smart home that has been
made can help turn on and turn off electronic equipment at
home, Smart home applications that are made can be connected
to the internet network, Smart Home applications can be
installed on Smartphones with operating systems Android
versions Android 7.0 – 7.1 (Nougat), Android 8.0 – 8.1 (Oreo),
Android 9 (Pie), Android 10 (Android Q). For the
implementation of using the application, the user must prepare
the IoT Smarthome Hardware that has been designed and then
connected to the internet. If so, household electronic equipment
can be accessed via Android Mobile. In working on the Internet
of Things Smart Home For Android, the author follows the path
of the Research Methodology.
