The calculation follows specific rules to exclude prices from stores with unclear VAT policies. The product currently leads in a comparison of similar items, offering connected radiator heads that let users control the temperature of their apartment room by room during specific time slots, without the need to manually adjust each radiator. The radiator heads are described as easy to install, requiring only a precision screwdriver for some valves. They come with a complete and user-friendly app that allows for precise temperature control, adjustable in half-degree increments. However, the cost of the product increases significantly with the number of radiators being used. Additionally, the connected heads are noted as being somewhat bulky, and they do not provide the ability to measure room temperature remotely. An alternative product, the Heatzy Pilot, is highlighted as a more affordable option for controlling electric heating via a smartphone, without requiring advanced technical knowledge. The Heatzy Pilot box allows for effective control of heating systems, but it is limited by the use of wire pilot technology, which does not support remote temperature adjustments. Despite this limitation, the Heatzy Pilot is noted for being designed in France, which may be a consideration for some buyers. Both products offer different approaches to smart heating control, with the Netatmo system providing more detailed and flexible temperature management, while the Heatzy Pilot offers a simpler and more budget-friendly solution. The choice between the two may depend on the user's specific needs, budget, and the size of their heating system.
