@Emil About needing the current state on demand rather than listing for updates... I want to write a script to adjust the brightness of lights throughout the day (dimming them hourly throughout the evening). This is also why I asked about sleeping in FlicScript.

I've already done this functionality through IFTTT using their scripting capabilities and jumping through hoops triggering Tapo shortcuts for turning lights back off after a delay if they were off before changing the brightness, but I'm hoping to make it simpler and more efficient through FlicScript.

The catch is that to adjust the brightness you need to turn the light on. So, if the light is already on, I can set the new brightness and that's that. But, if the light is off, it needs to be turned on to the new brightness and then turned back off so that when it's next turned on manually it will be at the desired brightness. To do this properly, I need to know if the light was currently on or off before adjusting the brightness so that it can be back in its previous state after the change is done. It's a little weird to have my lights turn on and off throughout the evening but not being blasted will full brightness lights later into the evening is nice.

It would be amazing if it were possible to adjust the "remembered" brightness without turning the light on, but from what you described before it sounds like that's not possible even with this more direct access to the Matter devices. Or am I mistaken? I haven't had a chance to test that deeply yet. Would writeAttribute be able to adjust the brightness without turning a light on?

@Emil Thank you so much, this is exactly the info I was hoping for! I've already done a proof of concept and it was so awesome to be able to toggle my Matter light via script, it's gonna be so much fun to control my house this way!

About getting the current status, the only way is via the asynchronous subscription? There is no synchronous way to just directly query the current status? If so, I can build a synchronous function around a subscription that is awaited and then canceled when the value is retrieved. Just want to be sure that is the best option before I move forward with that.

Also, out of curiosity, what would the writeAttribute method be used for?

@Emil Thank you! This is exactly the confirmation I needed to get started with my project! It's so cool to be able to script Matter devices!

I would like to have a run a script every hour to check the time and change the brightness of a light throughout the evening.

Is it possible for the Flic Hub LR to run a script on a schedule, or would I need to have the script running continuously manually create a loop using setTimeout to sleep for an hour? Or is there some better way to sleep in a loop, like how a script can wait for a button press but being trigger at a time instead of on an event?

Would it be horribly inefficient for the hub to have script sleeping for long periods using setTimeout or is that effectively the same as having a script running continuously and waiting for a button press?

Thank you!

@Emil Thank you! I would like to control plugs and light switches, both with basic on/off and some with dimming. I also have one color changing bulb I would like to be able to set color temperature and brightness on. But would like to just start with the basics of turning a plug on and off and then move to brightness and then to color.

Also, would like to be able to see the current on/off state of a device, is that possible?

If the specific devices are important, I'm using Tapo stuff:

Dimmable Plug: https://www.tapo.com/us/product/smart-plug/tapo-p135-kit/

Basic Switch: https://www.tapo.com/us/product/smart-switch/tapo-s505/

I'm curious about controlling Matter devices via FlicScript. I was able to use getNodes to list my Matter devices, but I'm having a hard time understanding exactly what would need to be passed to the sendCommand method.

Are there any working example scripts on how to control Matter devices?
