I have been using one in my bedroom for years, but I think it's starting to die. I was going to order a new one, but I was surprised to see that it is no longer available. Is there a newer device that has the same functionality?
They are gone. As you can see from your link. They sold them for $9.99 to sell them out. If there is one in development. It has not been mentioned. Publicly yet.
Smartenit makes a 5010H EZURIT module. I don't know if it could do what you want to do. As I have no experience with it. The web page has a good description of what it can do and a users sheet you can download to look at. https://smartenit.com/product/ezuirt/
One of the Amazon Merchants. Is showing they still have one new 2411R available.
You may want to ask in the UDI Forums. In the modules drop down list of modules in 4.7.3. Is a 03 0F EZX10-IR module. I know some modules model numbers changed when Compacta became Simpiehomenet and then Smartenit.
