I am referring to the script I built to allow control of Lutron Caseta within ST. It requires a middle man server of some sort which can be a Raspberry pi or other computer that is always on. It works very well and is fast and reliable. I have not released the code that adds the ability to add Pico remotes and control ST device with them just yet because I am not quite finished with it. I can confirm however that assuming you have the PRO version of the bridge the Picos do work. For just regular control either bridge will suffice. Check it out and if you have questions feel free to ask in that thread.
