Basic understanding of scenes

[AustinKirby]

I've looked for these answers in previous posts but haven't found them. Maybe I'm not searching correctly so forgive me if this is a repeat.

 

I have 2 dimmer switches (2476D) installed. One is the load for 5 can lights in the kitchen. The other has no load. I'm setting them up in a scene to act as 3-way dimmers. I want the ON level to be 50%. I created a scene [Kitchen Cans] and added both dimmers as controllers and set the ON LEVEL to be 50% and the RAMP RATE to be 2.0 in the scene and on each node within the scene (not sure why this appears in both the scene and the nodes).

 

The primary (LOAD) dimmer works as expected. Tap the top button and the lights brighten to 50%. Tap the top button again and the lights go to 100%. Double tap the top button and the lights go FAST ON. The LED's of both the primary and secondary dimmers report the status of the lights correctly. Life is good.

 

When I tap the top button of the secondary (NO LOAD) dimmer the lights brighten to 50% and the LED's on both dimmers show 50%. So far so good. If I tap the top button of the secondary again the LED's show FULL ON but the lights stay at 50%. The primary dimmer's LEDs stay at 50%.

 

How can I make the secondary dimmer act just like the primary?

 

Thanks for your assistance!

The Primary switch where the load is physically being controlled knows the difference between the first tap to 50% and the second tap that results in 100%. When the non-load controlling device On is tapped it sends a command to the Primary switch which reacts according the way the Scene has been defined (Responder On Level of the Primary switch). When the non-load controlling device On is tapped a second time the same command is sent to the Primary switch and it reacts exactly the same as the first command as it is acting as a Responder device in both cases and is obligated to react the same way. The first tap 50% second tap 100% is a characteristic unique to the device where the paddle is being tapped.

 

It would be necessary to trigger an ISY Program from the Secondary swithc and have the Program produce those results through program logic.

If you push and hold the slave switch, that will ramp the master switch up the rest of the way in unison with the slave (and vice-versa).

 

But as Lee said, as far as Insteon commands go, when you click "on", it sends an "on" signal over the power line. And "on" means 50% per your scene definition. Scenes don't know the difference between "on" clicked when light is already at 50% and "on" clicked when light is off. So whichever button you click "on" it will cause the other switch to go to 50%.
