Another thing I noticed is that when turning on the heat the valves were only opening halfway (40% sometimes 60%) and it would start regulating from there (slow). To counter this issue, I have some automations in place where I set the preset to boost when the preset goes from eco to comfort. Meaning that when the heat is turned on the valves open at 100% after a preset time the regulation starts, this time it starts at 100% not at half way. You can see how much you're heating Many smart heating apps allow you to monitor your energy use, making it easier to see where you could be saving money. A list of all the entities is added, and a Thermostat Card which allows you to set the target temperature. Smart radiator valves are great if you want complete control and transparency over how much you're using your heating.

Limited functionality without a smart thermostat You need a compatible smart thermostat if you want to get everything that a smart radiator valve has to offer, as this will allow your valves to communicate with the boiler to turn it on and off.

We have another new addition to our Home Assistant smart home setup with a Zigbee controlled thermostatic radiator valve (TRV) installed on the radiator in our loft workshop. You can change the settings remotely You don't have to go round your whole home changing each valve's settings, if you want to heat rooms differently.

The TRV has a setting only available in Zigbee2MQTT called "local_temperature_calibration" This allows you to add a temperature offset to allow for localised heating by the radiator or other heat sources. Adding to Home Assistant Home Assistant screen with TRV controls Having TRVs installed on your radiators allows you to set the temperature in individual rooms. This makes it easier for you to keep rooms at a consistent and comfortable temperature and save on heating bills by only heating the rooms you need to.In the past, we have used a basic manual-controlled TRV on the loft radiator, which runs from our gas-fired central heating system with the TR set to turn off once the temperature reaches a set point. The function of a smart radiator valve (or SRV for short) is exactly the same, but with these four key advantages: You can easily set up heating schedules. For example, the heating can be turned off in all the rooms but the office during the day, and then be turned on low in the bedrooms and higher in the living room during the evening.

First of all I noticed that when you have the window open detection on the valve act strange and becomes useless. So deactivating the feature is my first suggestion. When compared to standard thermostatic radiator valves, the smart alternative is a great upgrade. The added convenience of simply programming schedules as well as other intuitive functionality make them a worthwhile investment. However, it’s important to note that they may require a smart system/controller and they aren’t standalone. This is due to the internet connection requirement, which allows them to be remotely controlled via a smartphone app.Other brands, including Tado, Netatmo, Eve and Energenie did not provide us with specific information on update support periods. Put the correct adaptor on the valve (most smart radiator valves come with adaptors for the most common valves)

Industry Connections: We maintain close ties with manufacturers and brands, offering insights into trends and upcoming products. The Exposes screen below shows all the available settings for the TRV. Many of these are not editable in Home Assistant, so that you can update these in Zigbee2MQTT. We reached out to the biggest brands to find out more about support policies, and some are far better than others. Unlike a smart thermostat, you can install a SRV without needing the help of a professional. In most cases, you simply:However, if you don't own a smartphone or don't like using one, you're unlikely to get the full benefit out of a smart radiator valve. You can also set up heating schedules within the app to change the thermostat temperature throughout the day. In the diagram above, the thermostat is located in the living room. So you could set it to 18°C and also schedule this to change to 20°C between 7pm - 8pm, making it nice and cosy for you in the evening when you settle down in front of the TV.
