The table helps to find the corresponding percentage value for a certain PWM value if required. PWM values are the values that can be set in the function test from 0-1000 of the SunRiser 4 and 8. The graph shows the dimming curve, which is not proportional due to the gamma correction. See FAQ.

A well-known problem in many areas that have something to do with light, such as LED control or photography, is the subjective perception of brightness in relation to the actual power of the light. The problem here lies in the characteristic curve of the human eye. This is not linear, or more precisely: it is almost logarithmic. This makes it possible to perceive a very wide brightness range, from a full moon with ¼ lux to normal desk lighting with 750 lux to a bright summer day with up to 100,000 lux. Such highly dynamic signals can only be handled with a logarithmic characteristic curve.
To counteract this effect, there is the so-called gamma correction. Mathematically, this function is a power function with an exponent, often called gamma for short, as the only parameter. We have now added exactly this function to the daily planning. Pre-calculations, previously made with more powerful computers, increase the accuracy and relieve the comparatively small processor of the SunRiser.
In the function test, on the other hand, we work with the direct power value, i.e. the value 1 to 1000 stands for the actual power that the LED consumes, 500 would therefore mean that 50% of the maximum current power is applied. If you now specify 50% in the daily planning, this means that the planning tries to produce a 50% brightness, this is then approximately at the value 32 in the function test (one cannot say this exactly because the time factor also plays a role here and therefore the final value sometimes deviates in order to improve a smoother transition to the next stage).
In planning, however, for users who want to have full control over performance, is to create an option that turns off this gamma correction and thus does an absolute, linear performance fading over the set time period. A further step after that would be the possibility to adjust the gamma correction instead of just switching it off.
Rain is handled in fronts in the same way as thunderstorms, i.e. a rain front is defined randomly in between, but since the rain tries to work off a certain % of rain per day, it is not (currently) possible for the user to influence this. Please note that the rain always occurs in combination with the thunderstorm, as long as a thunderstorm is set.
The entire web frontend uses an API to bring your configuration to the SunRiser. This API allows you to set the configuration, install firmware or any other functions you have in the web interface.
The communication for this runs as a MessagePack over HTTP from the SunRiser. We plan to add at least one more API via GET parameters to be integrated in systems like Fhem. On request we will also document the MessagePack API, but we plan to do this only for the GET API.
In the expert menu we have provided a function that allows you to copy back and forth between the programmes of the weekly planning or the daily planning. The markings in the programme or the daily planning are converted into comma-separated lists with the minutes of the day and the performance alternating. Simply copy from one field to another. You can also edit the values directly here, just make sure that the daily minute can be a maximum of 1439 and the power a maximum of 100.
No, the clouds and rain are not visible when the brightness setting is set to 0%, because they only work by lowering the brightness for a short time. Nevertheless, the SunRiser tries to maintain a certain minimum brightness.
The probability refers to the complete day, i.e. to see clouds (or rain) all day, you must set the probability to 100%. If the probability is set to e.g. 50%, the SunRiser will literally flip a coin every day and if it is heads there will be clouds. It is still possible that the amount of clouds or rain on these days may be very low to almost non-existent.
The rain simulation and the cloud simulation differ primarily in the commonality and in the duration of the brightness changes. A raindrop is a short darkening, while a cloud can darken over a longer period of time. Also, with clouds, all LEDs are connected together. If 3-4 LED bars are assigned to the cloud simulation, they all darken together. When it rains, on the other hand, all LED bars produce raindrops independently to support the image of a "chaotic" rain.
