To add smart control for your central heating and hot water system, you can use a platform like Home Assistant to do so. Home Assistant is a free, open-source home automation platform that allows you to control various devices and systems in your home using a single interface.
Use the Home Assistant interface to monitor and control your central heating and hot water system. You can access the interface from anywhere, using a web browser or the Home Assistant app on your smartphone or tablet.
Configure automations in Home Assistant to control your central heating and hot water system based on your preferences. For example, you can set up automations to turn off the heating when you leave the house or to turn on the hot water in the morning.
Connect your central heating and hot water system to Home Assistant using the appropriate integration method. For example, if you have a compatible smart thermostat, you can connect it to Home Assistant using the thermostat integration.
Make sure your central heating and hot water system is compatible with Home Assistant by checking the list of supported devices. If your system is not on the list, you may need to purchase a compatible smart thermostat or other device.
