Idea:
- Saving energy by turning off heating/lighting when leaving the apartment.
- Inputting the time you are away from the apartment so that the heating is turned completely off and turned back on before you return.
- Shut down standby devices when no one's home.
Motivation:
- People leave lights on all the time when leaving the house which is a waste of energy.
- Houses are normally heated 24/7 which is also a waste of energy when no one is there.
- Devices on standby (tv, computer, phone charger) consume unnecessary power when not used.
- Addressing these 3 energy problems is going to save lots of energy/money.
- Calculating the cost of the devices and the savings that come with them.
Devices left on standby:
- TV 0.3w
- Audio system 10w
- Desktop computer + 1 screen 4w /notebook 9w
- Speaker (computer) 1.8w
- Microwave oven 3w
- Coffee maker 1w
- Phone charger 0.3w
- Printer (inkjet) 1.3w
- Induction cooker tops 7.1w
- Washing machine 3w
Total: 36.8w
9h(work) + 8h(night)=17hours on standby on weekdays 8h on weekends
Total electricity savings:195 kWh in a year. With 7.1c/kWh electricity price amounts to 13,85e saved in a year.
Cost of equipment to acquire:
HomeMatic wireless configuration adapter LAN, 78.09e x1 = 1w
HomeMatic Wireless dimming actuator, 42.99e x2 = 2x1w
2.6kWh per year= ~0.18e
Total: 164.07e

Presenting a home automation protocol: Z-Wave
- Z-Wave is a RF(radio frequency) control protocol designed to achieve reliable communication and operation between different products from different manufacturers.
- Operates in the 900MHz band which is impervious to interference from Wi-fi and other wireless technologies like Bluetooth.
- Enables the control of lighting, electrical outlets, fans, shades, drapes, irrigation, thermostats, security systems, door locks and more.
- Control available from various platforms: wireless keyfob, wall mounted keypad, internet connected tablet/phone/computer.
- Z-Wave devices create a mesh network, with every device acting as a repeater for information. If one device fails the information is routed through another device.
- Over 1400 interoperable products available from over 330 manufacturers, over 40 million products in use worldwide.
