Make sure that the thermostat is properly powered and check that the HomeKit code used is the one used on the thermostat (see "How to recover my Smarther with Netatmo connected thermostat HomeKit code?"). If this is the case, reboot the thermostat by doing a 5 seconds press on the button on the bottom right corner until you hear a beep (see "How to reset Apple HomeKit on my Smarther with Netatmo connected thermostat?").

The connected thermostat cannot access the Internet via a public Wi-Fi network (hot-spot) or via a company Wi-Fi network, and these networks are therefore not suggested. If your personal Wi-Fi network does not appear in the list of Wi-Fi networks suggested, first check that your smartphone is within range of the Wi-Fi network, and move closer to the Internet router if this is not the case. If your Wi-Fi network still does not appear in the list of available networks, it is probably because it is hidden: manually enter your network's SSID (name).In case your connected thermostat cannot reach the Wi-Fi signal because he is too far away from your Wi-Fi router, try to install a Wi-Fi repeater in order to increase the Wi-Fi range of your router. You can also try to bring your Wi-Fi router closer to your connected thermostat, if that is possible.

The algorithm is your connected thermostat's 'brain' and allows it to make decisions and fire up the boiler based on: heating history, room temperature, setpoint temperature and the chosen heating algorithm.You can switch between the Hysteresis and PID advanced algorithm in the app settings: Settings > My Home > Room of your thermostat > My thermostat > Advanced settings.Hysteresis algorithmWith this algorithm, when the difference between the setpoint and room temperatures is within a given sensitivity threshold, the thermostat assumes the setpoint temperature has been reached.You can adjust the Hysteresis algorithm sensitivity threshold in the thermostat's advanced settings. If you use smaller thresholds (0.1 °C), the thermostat will be more responsive to room and setpoint temperature changes. With larger thresholds, the thermostat will be more tolerant to variations in these temperatures and will switch the heating on and off less often.NB: This algorithm is recommended for wood-burning stoves.Advanced algorithm (PID)The Proportional-Integral-Derivative (PID) heating algorithm is more intelligent than the Hysteresis algorithm, enabling improved temperature regulation with fewer oscillations around the setpoint temperature. It takes the specific characteristics of your home into account (thermal inertia, insulation, etc.).When you first install the thermostat, only the Hysteresis mode is available.Over the first few weeks of heating, the thermostat will determine the specific characteristics of your home, including its thermal inertia and insulation.The PID cannot be activated until the thermostat has completed this initial configuration.It can then be deactivated to switch back to Hysteresis mode.Comments • Settings can only be configured during cold periods, when the Thermostat is actively controlling the heating. • When the temperature in the home rises quickly, you are advised to use setpoint temperatures with several degrees' difference between Comfort mode and Eco mode to give the thermostat clear benchmarks. Specific issues • The advanced heating algorithm (PID) is only useful for systems with high inertia, and is therefore not recommended in cases where the standard Hysteresis algorithm is already producing excellent results (heated floors, etc.). • The advanced heating algorithm is not recommended for devices that require significant fire-up and shut-down times since this can adversely affect their good working order and lifespan (examples include pellet-fired stoves and some heat pumps). • The PID is automatically deactivated for all setpoint temperatures up to 14°C; there is no point in using the heating more often to turn it on or off when nobody is home. • For Netatmo Smart Radiator Valves, the system will automatically switch to PID mode once configuration is complete. Neither of the algorithms can be force-activated.

If you can't use the touchscreen of your thermostat, please check the following cases : if the Boost mode is activated, then the touchscreen will be disabled until the Boost mode ends. in any other cases, the touchscreen might have been disabled, you can enable it again in the Home + Control App : go to settings, select "Manage my home", select the room in which the thermostat is installed, select the thermostat and select "Advanced", then you will be able to enable or disable the 'Touch' function.
