What is Domotica
The requirements of a domotica or “Smart Home” system can be summarised under the following points:
- Monitoring your home environment (sensing) and
potentially controlling (acting upon) devices as a result of detected changes in the
monitored environment e.g.
|Motion detection||Turning lights on/off
note how domotica allows equipment such as a passive infra-red (PIR) sensor to be used for both alarm and automation functions.
|Temperature and Humidity||Control heating, ventilating and air-conditioning (HVAC) devices
|Light levels||Turn lights on/off
|Smoke, Carbon-monoxide and flooding||Alarm functions, activate pumps and/or close taps
- Controlling devices on a pre-determined time basis e.g.
- Simulating the normal environment when you are actually absent.
- Waking you by opening the blinds and setting your radio to a news channel.
- Integration of manual commands from external devices e.g.
- Remote control of devices via internet or LAN connected apps e.g. on your mobile phone or
on voice input to Google Home/Assistant, Amazon's Echo/Alexa etc.
- Doorbells with internet connected intercom/Video and possibly lock release.
- GPS positioning to know when you are on the way home and make the house warm for your arrival.
- Organising and sequencing multiple commands to various devices (from multiple suppliers) to create a homogenous automation experience.
These groupings are known as Scenes, Skills or Activities depending on the control system involved.
- Close the blinds and/or dim the lights, turn on the TV, sound bar and your set top box with a single
voice command or single press of a button.
We could reduce this list to sensor and action or actions but adding timed commands and
remote voice or app control brings more relevance to the current domotica technologies.
