Heated pipes are heating floor concrete and then warm floor of a room heats all space. The pipes in the floor are installed in a certain order to form loops, the beginning and the end of each loop is connected to central manifold.

Smart Heating part 1: choosing boiler and thermostat
Heating is very important part of home. You have to maintain optimal temperature for maximum comfort at home. With this in mind, while renovating home I have redone all the heating system with a modern one. Now there is underfloor water heating in basement and first floor, radiators in the second floor and garage. New boiler, water heater and all the pipes and accessories.
This is a part 1 of a 4-part blog series.
The biggest challenge was, that in my smart home I want to control every element of heating system remote, by phone, watch and by voice.
First of all, had to choose gas boiler.
Mainly there was 3 major brands to choose from for me: Viessmann, Buderus, Junkers.
Viessmann has the biggest price tag if the boiler has capabilities for some automation.
Junkers is the simplest boiler with no smart automation integrated. And the Buderus is in the middle of two of them. All other parameters of competing models of these 3 brands are almost the same. Maybe it is just some of marketing stuff about the gas burners and their efficiency.
Viesmmann with automation capabilities has too high price tag, as almost the same functions and parameters are present in significantly cheaper Buderus model. With this in mind I have bought Buderus Logomax Plus GB172i-24 gas boiler. Continue reading Smart Heating part 1: choosing boiler and thermostat
While building smart home you will come to point when you will want to add remote control to device or appliance which does not have smart capabilities. It may be something like desk lamp, fan, monitor or something similar. You can do it with smart plug. The only requirement is needed, that when you plug in desired device to electricity it turned on without requiring pressing its physical button.
There are many options of smart plus in the wild. Some has only on/off possibilities: WeMo, TP-Link, D-Link, iDevices has smart plugs of this kind. Some are smarter and can show you how much electricity the plugged-in device is using. Major manufacturer of smarter plugs are: Elgato, WeMo, Belkin, iHome. But if you look for HomeKit integration, there are smaller number to choose from.
Now I am using Elgato Eve Energy smart plug. It has HomeKit support, energy monitoring and works over Bluetooth. Continue reading Smart Plug

Apple Home App setup
HomeKit is the protocol for smart home devices secure communication to each other. And the beauty of it is that all HomeKit compatible devices can be managed from one application on the phone – Home by Apple. One app to manage it all means less mess and less frustration for opening the right app to unlock the door or to turn on the lights. All HomeKit enabled devices can be controlled by voice with Siri.
It is recommended (I even would say it is mandatory) to have Apple TV gen3 or gen4 at home for remote access to HomeKit devices. Apple TV as a bridge for HomeKit is good not only for remote access. If some gadgets, for example August smart Door lock or Elgato Eve thermometer works over Bluetooth and does not have dedicated bridge – they can automatically connect to Apple TV by Bluetooth and to be ready for access from anywhere.

From outside any part of door lock is not changed and can be operated by key. In the inside smart lock replaces thumb turn. Continue reading Smart Door Lock
