A smart home is only as good as how it works unnoticed in everyday life. Below we describe how a Yabune Home system is built in an apartment or family house: what runs locally, what happens when the internet goes out, and what can be done with an already finished home without renovation.
The heart of the system is a local center
The control runs locally in the property. The center is a small single-board computer (Raspberry Pi) or an industrial mini PC, depending on the size of the system – the point is not the box, but that it is reliable and that the data remains local. The center brings together heating, cooling, lighting, shading, security devices and measurement: one interface, regardless of manufacturer.
Works even if the internet goes down
The system works on the home's own network, so scenes, schedules and automations run even without the internet. Remote access is provided via an encrypted connection, not via a manufacturer's cloud; the phone application uses the internal address at home, and the encrypted connection when away.
Based on Home Assistant, with its own additions
The system is based on Home Assistant, one of the world's largest open source smart home platforms. We connect wireless devices via Zigbee (Zigbee2MQTT), Z-Wave (Z-Wave JS) and Wi-Fi, the messages from the devices reach the center via an MQTT broker (Mosquitto), and the network is typically built from TP-Link Omada devices. Thanks to this, it can work with a wide range of devices; and we add what is needed for a production system: the selection of proven devices, our own integrations for devices that the platform cannot talk to on its own, and operation.
Smartening an existing home without demolition
You don't need to build a new home to make it smart. With a module hidden behind a light switch or in a junction box, existing lighting, blinds and heating can be controlled without having to open the wall. This also works with alternative switch connections, and we can pre-set what the system should do after a power outage. We connect the devices locally, on our own network – most often our partner, Shelly We use its modules.
The existing air conditioning can also be included: we make the indoor unit smart with an infrared controller, regardless of brand. This way, the air conditioning appears in the same system and on the same interface as the heating, and is integrated into the temperature and humidity control.
How to get started
The cheapest step in construction or renovation is good preparation. technical preparation On page 1, we have collected what is worth building in the structural and electrical installation phases by area. In a finished home, we start with the survey, and this reveals what can be solved without demolition.
