All the sensors mentioned in this article work on the same principle for external blinds<\/a>, aluminium and screen roller shutters and awnings. They are small components up to 20 cm in size and are divided into two basic categories – safety and comfort<\/strong>.<\/p>\n <\/section>\n\n\n

\n \n

Safety sensors<\/h2>\n <\/section>\n\n\n
\n \n

They ensure safe operation of the outdoor shading and protect it from damage. As safety sensors are supplied wind<\/strong> sensors. <\/p>\n <\/section>\n\n\n

\n \n

How do wind sensors work?<\/strong><\/p>\n <\/section>\n\n\n

\n \n

We set a wind speed limit at the factory where we have tested that the blinds will not be damaged and will stay safe. During installation, the installer sets the sensor to this wind speed. Once the sensor has measured this wind speed, it will then instruct the motor to pull the blinds to the top end position and conceal them under the cover sheet or in the box.<\/p>\n <\/section>\n\n\n

\n \n

Comfort sensors<\/h2>\n <\/section>\n\n\n
\n \n

These only serve to increase customer convenience. There are three types of comfort sensors:<\/p>\n <\/section>\n\n\n

\n \n

1. Temperature sensor<\/strong><\/p>\n <\/section>\n\n\n

\n \n

It measures the air temperature. The user sets a threshold that determines when the shading should be pulled up (to warm the room) or pulled down (to stop overheating). You can use the sensor to measure the temperature outside or inside. For example, if you buy a wireless sensor, you can leave it outside in summer and move it indoors in winter.<\/p>\n <\/section>\n\n\n

\n \n

2. Solar sensor<\/strong><\/p>\n <\/section>\n\n\n

\n \n

It measures the intensity of sunlight (brightness). Compared to a temperature sensor, it can react faster to the movement of the sun and clouds. It is typically used during sunset and sunrise. As soon as the sunlight drops below 100 lux in the evening, for example, the sensor instructs the motor to close the blinds or roller shutters. And in the morning, at sunrise, it will open them again in the same way.<\/p>\n <\/section>\n\n\n

\n \n

3. Rain sensor<\/strong><\/p>\n <\/section>\n\n\n

\n \n

It\u2019s the only one you can\u2019t buy alone. It\u2019s always linked to a wind sensor. In the past, sensors in this combination were widely used as frost protection (as soon as the temperature dropped below 2 \u00b0C and it rained, the shade was pulled into the box), but today\u2019s smart motors already have integrated frost control of the slats, so rain sensors which recongnize snowfall, for blinds and roller shutters are partly losing their importance. However, rain sensors are now used for awnings, which are more exposed to rain on terraces and balconies. <\/p>\n <\/section>\n\n\n

\n \n

How do the sensors connect to the shading?<\/h2>\n <\/section>\n\n\n
\n \n

The sensors communicate with the motors wirelessly<\/strong> using a radio signal\u2009\u2014\u2009so you can only use them with motors that can receive a radio signal (which means all wireless motors from the NEVA range). You can only connect Somfy sensors with Somfy motors\u2009\u2014\u2009other manufacturers do the same. So always check compatibility with your shading supplier.<\/p>\n <\/section>\n\n\n

\n \n

There is no limit to the number of blinds or roller shutters that can be connected to one sensor. The sensor simply sends a signal and the motors receive it. Most installers will automatically set the motors for all windows the same way.<\/p>\n <\/section>\n\n\n

\n \n

\u201cI 100% recommend wind sensors for external blinds. The rest depends on your situation and experience with the temperature in your house. But you can always buy them later on,\u201d <\/em>says Jan Hrn\u010d\u00ed\u0159 from Somfy. <\/p>\n <\/section>\n\n\n

\n \n

What about the sensor hierarchy?<\/strong><\/p>\n <\/section>\n\n\n

\n \n

If you buy multiple sensors, priority is always given to safety<\/strong>, i.e. wind sensors. The moment the sensor detects a gust of wind, the shading is pulled into the box and cannot come down while the wind is blowing. At this point, the motors do not respond to instructions from other sensors, and will not even obey the user if he tries to pull the shading down using the controller.
Comfort sensors are equal<\/strong> to each other, and as soon as they detect a change in the weather, they immediately instruct the motor. In theory, this could lead to clashing if, for example, the sky clouds over (= instructing the solar sensor to pull up the blinds)<\/em> at the same time as the temperature exceeds a certain threshold (= instructing the temperature sensor to pull down the blinds)<\/em>. However, in practice this does not happen<\/strong> because most users get a smart home control system together with the sensors, in which they set conditions and scenarios that are not mutually exclusive.<\/p>\n <\/section>\n\n\n

Where to place the sensors so they can measure reliably<\/h2>\n <\/section>\n\n\n
\n \n

Sensors can be wired<\/strong> or wireless<\/strong> (battery operated). Wired sensors require construction preparation, so they need to be planned for early on. The cable is routed through the wall and the sensor is anchored to the fa\u00e7ade by means of wall plugs:<\/p>\n <\/section>\n\n\n
