How To: Make a Simple/Cheap Scene Controller (with video)
-
Hi all - Another capacitive version with an "out of the bottle" keypad - 4 buttons. Like AWI's version, also toggles between 'Scene ON' and 'Scene OFF', but states are kept in a variable (keyState) - LEDs added for better toogle visibility. Capacitive routine found at http://www.arduino.cc/playground/Code/CapacitiveSensor
Great post from @petewill and nice version from AWI. Thanks!

My domoticz found S_SCENE_CONTROLLER sensor but there is not any devices for such a hardware. Do you know how can I control scene with it?

@Michal-Mormon
S_SCENE_CONTROLLER can send messages V_SCENE_ON and V_SCENE_OFF. If you send those messages for the first time, domoticz will create new switch with the name 'scene'. -

I found it as 'Scene' switch but this example send only V_SCENE_ON the first time (the switch is still ON later) -

Yes, exactly! It looks like without scene_off sent from scene controller in domoticz it will be one-time action (since if this scene switch is switched on you cannot switch it on again). You can try to setup automatic switching it off in domoticz. -
I added 2 lines and works perfect with Domoticz:
MyMessage scene(KEYPAD_CHILD_ID, V_SCENE_ON);
MyMessage scene2(KEYPAD_CHILD_ID, V_SCENE_OFF); //added linegw.send(scene.set(keyInt));
gw.send(scene2.set(keyInt)); //added line -

@petewill Any news about the 2.0 code? I am in the process of making scene controllers in the different rooms but can't get it to work.
@dvr123 No, not yet :grimacing:
My thermostat project has taken priority over everything because I need one in my house. I have a prototype working but I need to finish it. It is taking much longer than expected and I also haven't had much time lately. Sorry. -
Hi Guys,
I've been trying to compile this sketch without any success. I keep getting the following error when compiling
#error No forward link or gateway feature activated. This means nowhere to send messages! Pretty pointless.Can anyone help? thanks

@Matt-Pitts I still haven't had time to convert/test the sketch for version 2.0. If you want to take a shot at it there is info here: https://forum.mysensors.org/topic/4276/converting-a-sketch-from-1-5-x-to-2-0-x
I will get to it eventually I just have other projects that are consuming my time right now. Sorry.
