Since Harmony is phasing out their remotes. (Which I’m sad about) We did have a discussion about just that. But, no decisions have been made at this point. We have a long list to cover. Given it can be controlled via Node-RED, it might not be something we directly integrate out of the box, but perhaps after in an update. But it also matters how extensive the integration is. I know that there are some other things that will take priority, like thermostats and ecosystems of the like. Everything will happen in an order, but we will do our best to address devices as we move through things.
Don’t forget that if it’s not directly supported (LE, NR, etc), you can still keep devices connected and integrated using you other HUB as a controller until such time. In the long haul, it makes it less painful to move. It’s on your time. So you can do it right.
