• Energy from renewable sources not being utilized properly
• Best time for running appliances is not known
• Wastage of energy
• No clear monitoring available at individual appliance level

Sivis is a smart meter which can solve the problems mentioned above. It can redirect all the extra energy to the power grid, suggests user to run the appliance when renewable energy is abundant, give statistics of energy usage at appliance level and also provide user with patterns of his/her energy usage. This also contacts different services like weather station, calendar of the owner and customizes some of its functions.

• No such use of renewable energy
• User does not know what is the energy being used by individual appliance
• User has no way to determine when can he run appliances so that they run on renewable energy
• User doesn’t get reports on the renewable energy usage

• Uses Renewable Energy and power grid
• Supplies extra energy to power grid
• Energy saving
• Energy supply
• Reduces CO2 emission
• Flexibility of control
• Suggestion on equipment usage

• Renewable energy would be fully consumed i.e, no wastage of renewable energy
• System checks weather updates and runs the appliances when the renewable energy is available to run the appliance
• No storage of energy in batteries giving no scope for pollution when batteries are to be disposed
• Extra energy being supplied to power grids would reduce the necessity of energy from non-renewable sources of energy
• Reports of energy consumption is provided to user which can bring a change in user behavior

• KNX - is a system of sensors and actuators joined together by a “bus cable”.
• Administered by the KNX Association;
• 339 members/manufacturers from 37 countries;
• KNX devices are installed, programmed and parameterised by fully qualified system integrators;
• Accommodate wide range of functions;
• KNX based products are compatible with products from all manufactures;
• Supports all communication including Powerline (PL), Radio Frequency (RF), IP/Ethernet/WLAN
• System (power supplies, programming interfaces) and end devices (sensors and actuators);

• Smart Meter can be expensive (now).
• Time consuming in terms of generation and load of renewable energy.
• Maintaining grid reliability requires precise synchronization of voltage and current.
