I have to cases, one with netatmo Home coach, one with Tado Smart AC Control, where I'cant use my homekit code. The Homekit feedback is "accessory already added" and reset the accessory. But no way with reseting, I get the same Error: it is like a ghost homekit code. How can I reuse my accessory on Home ?
It is not possible to delete the home account because it has more than a hundred accessories!
