SmartThings shut down their Groovy cloud environment in Jan 2023 so Webcore isn’t available any longer. My understanding is that if you have a Hubitat hub, you can run Webcore on their environment and using a mirroring solution like Mira to monitor/manage your ST devices. Another option is the web-based Sharptools rules engine that has a free tier and a paid tier that offers more complex capabilities like using variables.
There may be a stock ST Edge driver for your Aeotec monitor, however, Aoetec provides one that supports your device here.
