Neuer Blogbeitrag: Monatsrückblick - Dezember 2025 🎄

[mrfloppy]

In meinem Blockly steuere ich mit 3 BWM mein Kellerlicht.
Das Blockly funktioniert soweit , nur wird bei jedem mal wahr
der Block "steuere Brightness mit 100" immer wieder ausgeführt obwohl eh schon auf 100.
Wie kann man das schön lösen und Steuer Befehle einsparen?

Danke LG Thomas

@mrfloppy bitte einen Screenshot vom Blockly zusätzlich zeigen

[paul53]

@mrfloppy sagte: "steuere Brightness mit 100" immer wieder ausgeführt obwohl eh schon auf 100.

[Zamecnik Jindrich]

@mrfloppy Here are some ways to avoid unnecessary repeated brightness controls in Blockly when controlling a light:

1. Use a variable to store the current brightness value. Check if the requested value differs from the variable before setting brightness. For example:

if (brightness != requestedValue) {
  set brightness to requestedValue
  set brightnessVariable to requestedValue
}

2. Use events/callbacks so brightness is only set when an explicit change is made rather than constantly checking. For example, have a "when brightness clicked" event trigger the set brightness block.

3. Use a timer to limit how often the brightness check runs to avoid spamming updates.

4. Only update brightness when other state changes occur - for example when a light is turned on/off, reset the brightness afterwards.

5. Create a brightnessChange() custom function that gets called instead of directly setting brightness. Have this function implement the checking logic to prevent unnecessary duplicates.

The key ideas are using variables, events, or cooldowns to determine if brightness needs changing rather than directly setting it continuously. This will help optimize unnecessary commands.

@paul53 Da reicht doch auch einmal auf Wert prüfen. Der wird immer wahr egal welcher Trigger ausgelöst hat. Oder übersehe ich da etwas?

@dr-bakterius sagte: Da reicht doch auch einmal auf Wert prüfen.

Nein, man benötigt eine Oder-Verknüpfung der Werte. Sonst kann es passieren, dass zwei BWM auf false gehen und dadurch mehrere Timer laufen, die sich nicht mehr stoppen lassen.
Außerdem ist immer noch Bewegung, wenn erst zwei BWM Bewegung melden und dann nur noch ein BWM.
