This is a bit of a kludge, but it works…
I set up a nighttime “Night sustain” mode. The mode has what lights I want on at what level, so I can say I want “X, Y” lights on or “A, B” lights on at say 10% as night lights.
Then I trigger it a couple of times per night, say at 2 am and 3 am, etc. What that does is set all the lights into a specific mode, no matter what their current state. So if someone gets up during the night and turns up a light in the bathroom (which on dimmer at 10% as a night light), and they forget to turn it back down, or turns it off – the “sustain” mode, then resets it to where I want it to, after a while.
It’s a kludge – you can be staring into the mirror at 159 am, and at 2 am the mode will turn the light down to 10% while you’re still in the bathroom. So its not perfect.
A software option with logic will work better (turn down the lights 20 minutes after they have been turned up if your in mode “sustain”, for example). But for a quick 2 minute fix, it works. The software logic is on the list to implement in the future, along with some motion sensors to turn up the lights if someone gets up and is moving around.
