Ramp Rates not being honored?

[GodOfCheese]

I'm trying to dim the lights in a scene very slowly, however it seems that my switches are ignoring the Ramp Rate settings for the scene. 

 

The scene contains only three Insteon 2477D.v45s as controllers.  I set the ramp rate on the scene to  9 minutes, wait a few seconds, then set to On, but the lights rapidly dim to the target level using the default rate of 0.1s. 

 

I've also tried creating a second scene using the three as responders, always having the ramp rate set to 9 minutes, and always with the target level set to like 20%.  No dice-- still uses the 0.1s ramp rate.

 

Then it occurred to me that the individual devices in the scene might need their ramp rates set locally, so I made sure to drill into each device in the scene and set the ramp rate to 9m.  Still dims in less than a second.

 

What am I missing here?

 

Thanks!

Setting the ramp rate to 9 min is equivalent to 0.1 sec ramp rate. The reason is that Insteon eliminated the 9 min ramp rate years ago, but the ISY maintains that value in the event that a user still has an older device that supported that ramp rate.

 

The maximum current ramp rate is 8 min. Any rate beyond that duration is ignored.

 

Note that the ramp rate is calculated from full on (or off) to full off (or on). If the current On-level is 50%, the the effective ramp rate is half the value selected.

Literal LOL!  That all makes sense now!
