Ramp Rates & Scenes

[chachdog]

If I have a scene with a ramp rate set to 9 minutes. Will an Off command to that scene use that ramp rate? 

 

The fade down is preprogrammed at a certain rate I think I read. 

 

 

I set a scene to be on. 

then change the scenes devices ramp rates to 9 minutes. 

 

I wait 45 seconds

 

then turn the scene off but the 9 minute ramp rate does not apply. it just goes right off. I see that the ramp rates have been modified but the 9 minutes does not seem to apply when turning the scene on and off. 

 

Also is it necessary to add wait times between commands? ie adjust scene xyz ramp rate, wait 2 secs, adjust scene wxy ramp rate, wait 2 secs.

Unless the device is a very old Dimmer a 9 minute Ramp Rate no longer exists.  8 minutes is now the max Ramp Rate for On/Off commands. 

 

Fade Up/Down does not use the On/Off command Ramp Rate.  Fade Up/Down uses something in the range of 2 to 3 seconds. Fade Up/Down requires a Fade Stop.

 

I have not found a Wait is necessary between Adjust Scene statements.

Ramp rate programmed for a device in a scene is the same for both on and off rates unless it is adjusted between on and off calls.

If you set a ramp rate of 9 minutes, then the ramp rate is ignored.

haha that is pretty funny. I went to the extreme to test a theory and I went a bit too far. That doesn't make sense from a UI perspective. why not take that out ? or is that the point if for some reason you want to ignore the ramp rate.

If you happen to have some old Insteon equipment as I do a 9 minute ramp rate is still useful.  It is always good to read the Specs section on the retail page for a device which indicates what the device actually supports (now 8 minute max ramp rate).  Actually the ramp rate field runs from 0x1F (0.1 second rate) to 0x00 (was 9 minutes but now causes a 0.2 second ramp rate).  

 

The 9 minute value (0x00) could have come from not setting a ramp rate value which caused diagnostic issues because no one waited for 9 minutes.  Years ago SmartLabs solved that problem by having a 0x00 ramp rate field result in a 0.2 second ramp.

That's to accommodate owner's of older SwitchLinc's. You wouldn't want features of you current devices disabled in the event they're no longer included in the newest devices.

Thanks LeeG.  I forgot about the Fade Up Fade Down and Ramp rate.  The wording within the Universal Devices is confusing and should be changed. I will re-cap for others having this issue.

Fade Up/Down is a fixed rate that you cant control and is around 2 seconds.

Ramp rate controls how fast a light comes on and off within a scene.

When you set a scene use the on or off to utilize the ramp rate that is set in the scene. 

Using the fade up or down, will cause it to use a 2 second ramp rate.

Ramp rates set to 9 min will cause newer equipment to come on in .2 seconds.

If your scene lighting ramp rate is not working check the following:

1. Ramp rate not set to 9 min (use 8 min or less)

2. Do not use fade up or fade down to set the scene

3. Use the On or Off when Setting the scene.
