Block Weather station

This control element shows the values of the weather station and is at the same time the place where its protective functions are set: wind, rain, frost and heat alarm, the shading per direction and the dusk. This way awnings retract in a storm, for example, without anyone having to intervene. In addition there is a logbook of the alarms and a statistic of the weather curves.

Operation

Weather situation: Sunny, Cloudy, Rain or Snow (rain below 1 °C). If the weather station reports a fault, “Sensor fault” is shown here.
Gear: a tap anywhere on the element opens the dialog.
Temperature: the measured outdoor temperature in °C.
Weather symbol: matching the weather situation.
Wind, brightness, humidity: the wind speed, the brightness in klux on which “Cloudy” is decided (total brightness or the highest value of east, south and west) and the humidity. If the station does not measure humidity, the third line reads “Rain” or “Dry”.
Alarm dots: from the left wind, rain, frost and heat alarm. A dot is filled red while the alarm is pending.

The dialog

Symbols of the title bar: the gear opens the settings, the list the logbook, the chart the statistic (see below).
Temperature: the current value, below it the lowest and the highest value of today.
Measured values: the current wind, at Wind max. today the highest wind since midnight and at Rain today the minutes with rain since midnight. Rain amount, humidity, air pressure and wind direction only appear when the station delivers these values; up to seven rows fit.
Brightness: per direction in klux and the dusk in lux (or Yes/No if the station only delivers a dusk signal).
Safety functions: per field the state of a monitoring – off (switched off), active (it watches, nothing is pending) or red Alarm. For East, South, West and Dusk it reads Request instead while shading or dusk is currently requested. A tap on a field switches the monitoring on or off; this takes effect immediately, without saving.

If there is a sensor fault or the test mode is running, a red message line appears at the top of the dialog. For a fault, the cause is shown to the right:

Message at the error input – the weather station reports the fault itself.
Measured value implausible – the named value was repeatedly outside the sensible range. Usually the data type of the variable is wrong.
Values are not updated – no value has changed within the time Sensor failure after.

Settings

Group: the settings are ordered by wind, rain, frost, heat, shading, dusk as well as monitoring and test. The list can be scrolled with the finger or the mouse wheel.
On / Off: every tap toggles.
Limit: the current measured value is shown in brackets so that the threshold is easy to find. A tap opens the input.
Save: transfers all values to the controller; the cross discards the changes.

Monitoring	Switches the respective monitoring on or off. When it is off, the corresponding alarm is withdrawn immediately. Default: wind, rain and frost on, heat, shading and dusk off.
Alarm above / Alarm below	Limit from which the alarm is triggered. Default: wind 40 km/h, frost below 3 °C, heat above 35 °C.
Switch-on delay	For this many seconds the limit must be exceeded continuously before the alarm is set. Prevents alarms caused by short peaks.
Drop-out delay	For this many minutes the value must stay below the limit continuously before the alarm is withdrawn. If the limit is exceeded again in between, the time starts over.
Hysteresis	Distance between switch-on and switch-off point: for the wind in km/h, for frost and heat as Hysteresis temperature in K, for shading and dusk as Hysteresis brightness in percent of the limit.
Evaluate rain amount	The rain alarm follows the rain amount in mm/h (Alarm above, default 0.5 mm/h) instead of the rain message. Only useful if the station delivers a rain amount.
Only with precipitation	The frost alarm only comes when rain is reported at the same time – this protects against icing without retracting needlessly in dry cold.
East, South, West	Shading per direction: on/off, limit in lux (default 30000), switch-on delay in seconds and drop-out delay in minutes.
Input is a bit	The dusk comes as a switching signal instead of a brightness value. Otherwise Dusk below in lux applies (default 10).
Sensor failure after	If none of the values temperature, wind and rain (or the sign of life) changes within this many minutes, the station counts as faulty. 0 switches this check off. Default 30 min.
Safety position	On a sensor fault the wind and rain alarms are set forcibly so that awnings retract, for example. Default on.
Repeat alarm every	Pending alarms are sent again at this interval (minutes) in case a telegram was lost. 0 switches the repetition off. Default 10 min.
Plausibility check	Values outside sensible ranges are discarded, the last valid value is kept. Default on.
Gust from deviation	If the wind exceeds the average by more than this value, the gust is recorded separately in the statistic. Default 15 km/h.
Test mode duration / Test mode	Start sets the wind and rain alarm forcibly for the set duration (1 to 60 minutes, default 2). This way you can check during commissioning whether the blinds move to the safety position correctly. The tap only starts the test and closes the window; other changes in the dialog not yet saved are not saved by it. When the time has elapsed, the alarms drop out by themselves.

Logbook

The logbook shows the latest events with date and time: wind, rain, frost and heat alarm, shading, dusk, sensor fault and test mode, each with ON (red) or OFF and the triggering measured value. This makes it possible to trace why an awning retracted. Exit closes the logbook.

Statistic

List: opens the selection with the view (temperature, wind, rain, humidity, air pressure), the time range and the bin, which deletes all recorded data after a confirmation.
Curve: for the temperature min, max and average, for the wind average, max and the individual gusts, for the rain rain duration and rain amount.
Arrows: to the previous or next view. Humidity and air pressure only exist if the station delivers them.
Time range: 6 hours, 12 hours, day, 2, 7, 30 or 90 days or the year; a tap opens the selection.

Setup

This section is meant for the installer of the system.

The control element is linked with the function block Block Weather station: first create the function block together with its variables, then right-click the control element and choose the function block. The variables are taken over, the text of the element gets the name of the block. Without a link, a tap on the element points this out.

The measured values go to the inputs of the function block; the first ten match the outputs of the block Weather station in order.
Which optional values (rain amount, humidity, air pressure, wind direction) are shown and recorded depends on which inputs are linked at the function block. The wind may come in km/h or in m/s; if both are linked, the larger value applies.
The alarms and the shading are outputs of the function block and are connected there with the blinds, awnings and windows.
The settings are stored in the controller. The controller records the statistic by itself.

Parameters

Display
Text	Title of the dialog. When linking, the name of the function block is taken over; default “Weather station”.
Statistic	Shows the chart symbol for the statistic in the dialog. Default on.
Cloudy below	Brightness in lux below which “Cloudy” is shown. The overall brightness is compared if it is linked, otherwise the highest value of east, south and west. Default 5000 lux.

Variable links

All variables are located at the function block and are taken over when linking.
