Yes I mentioned IR controllers for mini-splits. I was referring to the handheld remote controls that come with the systems.
It sounds like you’re looking for a device that can control multiple IR-based devices (like mini splits, TVs, space heaters, etc). And can pair to the hub with zigbee.
Still seems like a bit of a digression to me, but I think your best bet would be one of the broadlink controllers supported with this community-developed integration.
That connects to the hub over the LAN, not zigbee. I don’t think a zigbee-based device with similar functions exists.
