I don’t understand. I looked at the literature on this device, and I don’t see anything about “open” or “closed.” It’s just a switch. On or Off. In HA, you can certainly change those words, but it is the same information; basically just a True or False.
I’ve found ZHA plenty functional for basic switches. I’ve heard Z2M is more functional for some devices, but there’s also value in keeping the HA system less complex to maintain.
