Bug in Routine with Period of Time based on Sunset?

Bruce, the Low-Lux routine works, BUT I discovered that the transition to low lux (15 lux) must occur AFTER 1 pm. If I enter the 1 pm to sunset period with illuminance (lux) already BELOW the 15 lux threshold, the lights will not go on.

I started off with a low lux threshold around 40 and found the lights would not turn on during cloudy, dark days because the daytime high lux value was always below the 40 lux threshold. To get the routine to reliably turn on every day when the room got dark, I had to set the low lux threshold at a low enough point to ensure I would enter the 1 pm to sunset period with lux higher than the threshold. But, by setting such a low threshold, on sunny days, the lights turn on later in the day than I like.

Is there a way to create logic such that:

1. When the 1 pm to sunset period starts (at 1 pm) AND lux level is already <= threshold, turn lights on immediately at 1 pm.
   OR
2. When the 1 pm to sunset period starts (at 1 pm) AND lux level goes <= threshold during that time period, turn lights on.

The second #2 part of that logic works fine. But the first #1 part does not work.

You’ll need two different Routines because you have two different triggers and two different bounding conditions. Your case #1 above is triggered by when the time changes vs your case #2 which is triggered by the change in lux level. So, you need a second Routine like this:

If Lux <=Threshold (pre-condition)
Virtual Switch On (1 pm to sunset period starts)
Then
Turn on the lights

Thanks. I thought that might be the exact solution.

The lights just went on a moment ago. It’s a bright, sunny day today. My lux sensor faces north through a living room window, so it doesn’t get bright sunlight.
