Specification or Bug?

Hello,

I want to turn on a light the lighting by 40% with a 5753L.
Short Press of the Fuctions tab was changed from On Key to Recall 1, and Recall 1 of the Blocks tab was adjusted to 40%.
The On command comes out on C-Bus network when the sensor reacts first when Short Press of the Functions tab is On Key.
However, the set to 40% command comes out on C-Bus network for Recall 1 whenever the sensor reacts before it becomes Expiry time.
Isn't this a bug?

 

This is not a bug.

Recalls are what you can use to trigger events, such as a scene, in response to detecting movement. If the command was not sent out each time movement was detected, the scene would only get set once, and then never again, even after the lights were turned off.

As you see, it does increase network traffic a bit, but it is a necessary trade-off to get more flexibility in network configuration.

 

The repeated sending of the level command is needed even without scenes.

If one sensor is controlling one or more loads, the sensor starts timing from the last movement detected so that the turn-off event is avoided if there is always motion detected before this limit. For example, if the timer was set to 20 minutes, then the detector would only need to detect a second movement before the 20 minutes expires in order to keep the load on.

When there are more than two sensors controlling the same load, and movement is detected by one sensor, the load will turn on. If a second movement is detected within the timeout duration by the other sensor, the first sensor needs to know so it doesn't turn off the load, so it responds to the second sensor's level command by entering a passive state. If the first sensor again detects motion, it will again issue a command, and take over control of the load from the second unit. This mechanism allows only one sensor timer to be active at a given time, when multiple sensors control a single load or a single group of loads.

The extra messages on a network can get to a level that creates a problem if multiple sensors are used in a public area. 5750 and 5751 sensors incorporate a slightly different algorithm which delays the issuing of a command in such cases, but the basic operation remains the same.

 

Hello Newman and Don,

My customer request me that it wanted to choose the brightness of the lighting that lit with the sensor by himself.
I planned to use a Logic.
The group address kicked with On Key of 5753L sensor. and it was received with Logic of Color C-Touch. and the mechanism that the target light is lit by the brightness that the user had set was made.
However, little delay was generated until the lighting actually lit in this mechanism.
Then, two group address A and B were added to Logic of the target light. Recall 1 of 5753L is set to 40%, and group address A is kicked by this value. The target light turns it on directly and the light is turned on by the brightness of the receiving 40%. The command turns on group address B with Logic of C-Touch by the brightness of the user specification and is at the same time. The target light receives this command and changes brightness. The user's brightness specification should be over than 40%.
It is necessary to add two group addresses in Logic of the target light though this mechanism operated well.
I tried to test if two neither group address A nor B were adjusted to one.
I could not get my hopeness.

 

Selectable dimming with sensors

Yoshi,

I am not sure if this is what your after.

Have you considered the following:
Add a group address e.g "light 1" to your key input and set the button as a dimmer.
In the logic tab on the dimmer, add a group address for example - "sensor trigger". This needs to be added to the same channel as "light 1"
Set the logic channel to "MIN" in the dimmer.
Add the same address you programmed into the logic channel on the dimmer (sensor trigger) to the sensor, and set up the required expiry timer.
By using "MIN" logic, "light 1" will always remain at the lowest of the two addresses "light 1" and "sensor trigger"
With this set up, your client can control his lights, and dim them up or down, and retain the sensor control you may be looking for
