Internet of thing has already become a part of ordinary household in many countries. We use online assistant devices – such as Alexa, Google or Siri, we have washing machines which we can control through mobile device or we can start to cook dinner in the oven when we are on our way home. In these cases, the usage of Internet of Things is up to every individual, but in the next few years, every household should have device running online, which will help them to be more energy efficient.
European Union is trying to set some rules in order to be more energy efficient and be more eco-friendly to our planet. For that, they are counting also on Internet of things which should be used in gathering information about consumption of households in every country belonging to EU.
Directive 2018/2002 of the European Parliament and of the Council is editing the directive on energy efficiency 2012/27/EU, which concentrates on more ecological actions of countries in EU. The most current topic is reducing final consumption of heat and hot water of each facility. The goal of this directive is to ensure that the owner or tenant of a property will monthly (in Czech Republic it is now only once a year or every 4 months) receive detailed billing of their consumption of electricity and hot water. As a result, the owner or tenant can adapt their consumption according to their monthly billing.
This billing should be consisted of:
- Price and actual consumption of energies
- Comparison with previous month consumption
- Comparison with standardized consumer
- Composition of energy sources
For this reason, everywhere in Czech Republic, starting from the 1.1. 2027 there must be installed only electro meters which will be possible to read (count down) remotely. People can choose from 2 variations – “walk-by” systems for which a person must come nearby to the meter, or systems on the base of Internet of Things which automatically download the data and send it every month to the administrator. “Walk-by” systems have cheaper starting investment, but in long term, they are more expensive because of not automatic count down. That will mean that nearly every property in Czech (and hopefully EU) will have, by the year 2027, installed IoT device.
