You are right, same on the RO site.
I know that IKEA is keen on replacing all smart devices that use throw-away button batteries with new devices that use rechargeable AA/AAA (more eco-friendly). All their new 2024 products Parasoll (Door and Window Sensor), Vallhorn (Motion Sensor) and Badring (Leak Sensor) follow this trend.
I don't see a replacement for the Shortcut Button, maybe they think that the 2-button Rodret Dimmer (E2201) will suffice.
