its coming up that way on the Harmony BECAUSE the device is both a sensor and a switch. Harmony defaults to seeing the sensor side - no tthe switch side. THat would NORMALLY take a change in the harmony Groovy code that drives the Harmony integration - buuuuut. THeres a significant hitch here -
The Harmony Groovy intrgration dies with Groovy. So you wont be able to pull the devices into your remote that way anymore. Also Harmony support ahs already released notes to customers who asked that they do not intend to build an API / Edge integration.
There is an Alpha implementation of an Edge driver for Harmony here: [EDGE DEVICE] Simple Harmony Bridge **Alpha Testing**
Have no idea where the developer intends to go with it, but as they appear to be using dev mode on the hub and direct comms (Same way HomeAssistant does it) they theoretically could do just about anything.
I’d strongly suggest you switch your planning around that because everything else you have may go away when Groovy is decommissioned.
