Issue with command : Fade over time

[zvoyageur]

I am having a weird issue with fade over time. Actually it is more with the Wait for Event statement.

Basically, When triggered by a motion detector, I turn on a light (Eclairage corridor) to three different level according to time of day. 100%, 75% and 25%. that works fine.

The issue is with the rule machine rule turning it off. Basically the rule fades the level to 15% and when it reaches 15% it turns off the light. When it fire from the 100% or 75% level it works fine, but when it fires from the 25% level, it has a odd behavior. It turns off the light as expected, then turn it back on at the 15% level. This is confirmed by the logs that the fade over time act after the OFF statement

Here is the rule :

Since the rule has 24 steps (2 minutes at 12 steps per minute). The dim level from 100 % 75% and 25% have steps of respectively 3.5%, 2.5%, 0.416%).

At 100% and 75%. For the Wait test to be true, your have to be at the 24 of 24 steps, otherwise you are at 18.5% and 17.5% respectively at the 23rd step. Alls is fine and this works well

What I suspect is that since the wait statement use an integer for the comparison, at the 22nd step, it has decreased the 25% original level by (22x.416%=9.16%) thus reaching. 15.84%.

At 15.84% the wait statement using an integer for comparison trigger and turns off the light. But... there are still 2 steps left in the Fade operation , so at the 23rd step there is a dim command at 15.42% issued, and the lamp goes back on.

Any suggestion how I could work around this issue. Since I can not make a comparison with a decimal level to 15.0 ? The alternative would be to add a dumb delay of 11 seconds before the off statement to make sure that all 24 iterations are done, but this is not an elegant solution.

Any suggestions ?

Thanks !

Turn on the Action logging for this rule,, and post a screenshot of those logs for when it fails from 25% starting point.

To get around this: You could add "Stop dimmer fade " action right after the Wait, and also change the Wait for Event into a Wait for Condition

Thanks for the suggestions.

Following is the logs taken after the rule was triggered.

It seems to confirm that the dimmer level value gets 'truncated' to the integer value of the required level by the fade routine. That results in the same level being requested more than once when the steps are below .5%.

Highlights:
AT 21:51:59, The rule to turn off light at 15% triggered and turned OFF light when dim level reached 15.84%) 22nd of 24 dimming steps
At 21:52:04: The light turned back ON when a dim command at level 15% was issued when fade calculated a level of 15.42%) (23rd step of 24 fading steps)
At 21:52:09: The light were dimmed at level 15% again when fade calculated a level of 15.0% (24 step and last of fading)

[bravenel]

Your supposition appears to be correct. That is, the value kept step to step during the fade is decimal, but setLevel only accepts an integer. With the step size < 0.5, you can see how the saved value could be 15.9, then 15.5, etc. while the first of those sets the level to 15, but it's not done yet.

So just put 'Stop dimmer fade' before the off action, after the wait.

Thanks for the feedback.

Solution tested. It fixes the issue

Thus the Stop dimmer fade should be mandatory for most of my dimmer fades implementation as I like a slow dim...
