Hestia from Wikipedia is:
In the Ancient Greek religion, Hestia is the virgin goddess of the hearth, the right ordering of domesticity, the family, the home, and the state. (Wikipedia)
Hence a fitting name for the project around developing a smart home.
My smart home journey started with a few “smart” devices. Such as a connected IP camera to check on the dog, and a second generation Nest thermostat to start the heating when we were driving home. It really kicked off in 2015, when I joined everything up with a tool called Home Assistant (home-assistant.io)
In its simplest form, Home Assistant (HA) is an ecosystem, where you can put your smart devices together. This means you only need one website to control them all (little win!) but it also unlocks something very clever as your devices can now talk to each other (big win!!).
Via HA, it is possible to say, switch on your porch lights when your phone is close to your house, send a tweet when your 3d printer has finished its job, or even delay your dishwasher when electricity prices are high.
HA is not the only ecosystem available. But it is probably the most popular, completely free, open source and secure. I also closely relate to the founder’s vision for an automated home: https://www.home-assistant.io/blog/2016/01/19/perfect-home-automation/
The downside to HA is that it can be quite complicated to set up. What I (and my friends) have found is that it has become somewhat of a hobby. To tinker around to create the coolest automations, dashboards and even homemade devices.
