IR sensor perhaps?

@petewill Ah! I didn't think of exposing multiple sensors/devices! Ugh! I will think on this. The problem is, each button is momentary (not a switch/dimmer) so I'm not sure I have the experience to handle that. (good with electronics - not so good in the coding world) Although, I seem to remember others talking about momentary actions in the forums..... I'm sure it has been tackled.

@hek I didn't know about that device..... I'm going to check in to that as well.

Thanks!

Well, I made some progress today. I was able to sniff the traffic, determine the pulse width, and put together a simple sketch to test it. I had to modify the antenna on the transmitter as well as the one on the receiver inside the light. I'm now able to control it from anywhere in the house. Prior, only a few feet would work.

However, I'm still not clear on how I'll present this to the controller.

Here are the codes for the record:

Power= 010101101010010100000001
Red= 010101101010010100000010
Green= 010101101010010100001000
Blue= 010101101010010100001110
down = 010101101010010100000100
up= 010101101010010100010110

Pulse width was measured at 310 ms. However, using my ear, it sounds and works better if set at 298ms.

Any more thoughts on the controller side? Would really be helpful. I'm just not a very creative coder.

Thanks!

I'm forging ahead with multiple switches (lights) until someone can help me think through the best way to present to the controller. I'm trying to work out the logic to simulate a button-press.

When someone/something presses "on" in the controller, the sensor will determine which button/light was pressed, send the appropriate data and then toggle the device back off. I've never updated a switch status back to the controller. My use of "send" below is clearly invalid.

@tbully When you say controller, are you referring to the remote control or your home automation controller? If it's the remote control it will be difficult to get the commands from that. For my blinds, I don't use them. All controlling is done through my HA controller. If you do it this way your status will always be correct at your HA controller.

[tbully]

@petewill Good question. I meant the home controller. The remote is completely out of the picture now. Using your ideas, I was able to figure out all the codes and can send them successfully via a test script. The hard part is done, ironically!

I'm just not a great code guy.....

I haven't put that logic in to my script yet. Instead, I'm trying to figure out how to "bounce" a light switch. When the home automation controller sends an "on" for a certain function, I'll send the RF data and then switch it back "off" to be ready for the next command/"button press" later. That's the part I'm having trouble with....

[petewill]

@tbully I'm not exactly sure what your lights require but why do you need to send the off command to be read for the next command? With my blinds I just send the Up command then wait for the next command to come in. When I receive the down command I send that.

[tbully]

@petewill Because when the V_LIGHT sensor is switched "on" in Vera, I will fall in to the proper "if" condition above. However, I need to switch it back off after I send the data so I can later toggle it again. I wish there was a "button device" so I didn't have to worry about it.

  else if (message.sensor == RED_CONTROLLER) {
    Serial.println ("Sending RED data");
    //send 433 mhz RF data and turn switch back off
  }

[tbully]

With the help of @petewill in a chat session, I was able to figure out why I couldn't send messages back.

I was failing to instantiate:
MyMessage msg(RED_CONTROLLER,S_LIGHT);

I'm only concentrating on the "red" case at the moment. As you can see from the log, I'm sending a "0" back to Vera but Vera is not showing off in the console. ** Am I not resetting the state correctly?**

You're almost there! You need to change this line:

MyMessage msg(RED_CONTROLLER,S_LIGHT);

to this

MyMessage msg(RED_CONTROLLER,V_LIGHT);

[tbully]

@petewill ARGH! Of course! That was it! OK, this should get me going for a bit. Thanks so much!

I will work on this more and report back! Love these forums and how helpful they are. Hopefully, I will be able to return the favor someday!

[tbully]

I thought I'd report back with my code. The sensor is up and running. I don't like that I just had to present switches but I'm not skilled enough to use the "custom" field and make a control in Vera. (On/Off, Blue, Red, Green, Motion) So this will have to do for now. It's probably OK as I'm just going to use automation to actuate the switches.
