Switching power circuits - sockets, lights, blinds, pumps and other devices under 110-230V is one of the essential functions of an intelligent house. At Pi-Home, we are using Arduino Mega boards with Ethernet Shield, which control Arduino's compatible SSR relays connected with high power relays of the switchboard. More information and detaied scheme can be searched in the article.

One of the main reasons for NAS is - in addition to the convenience of having everything together - a backup of data. We prefer to use "automatic update" of second disc with RSync services. This allows access to deleted files for some time period and protect against cryptovirus.

The basic configuration is really simple. You learn how to change your default password, language and attach the discs where you want to store your data. We will also set up users to access NAS. The last and most important part is dedicated to replicating data to the next disk using the RSync tool - it protects your data from damage and lso provides protection against cryptoviruses by preventing access to the backup disk for any account.
