You just described my setup. I have my secure devices (locks) on the vera, everything else on OH. Works great! (Eventually once the security branch settles I’ll migrate the locks over to OH as well, but for now if it ain’t broke…)
Yes and no, respectively. In my OH network I have two controllers (a zs5 and a zs2, with zs5 being the master and SUC). While technically the zs5 pings the zs2 and sets up neighbors and routes for it, since the zs2 isn’t a switch or a sensor there’s really not much for them to say to each other. I suppose I could screw around with forcing a message from the zs2 to the zs5 with ozw or zensys, haven’t gotten around to it.
