I'm incredibly frustrated today after trying to add two different home care devices and failed after several attempts. Today I tried to add both a Meross light switch and an iHome plug-in switch. Both failed after several tests and all the usual troubleshooting repeated (make sure iphone / ipad in using a 2.4 ghz network), etc. They all failed spectacularly. I've added exactly the same devices in the past, but sometimes I had to repeat the process 8-10 times until "magic" (uggh!) Completed the pairing. Was there a place with good writing? I know a lot is going on under the covers - the phone needs to connect to temporary wifi devices, then the device needs to learn what real network (ssid) to connect to, then it needs both the phone and the decice to cut both. All of this happens undercover, without user visibility, of course. And I guess there's some kind of call to Apple to check if the HK device is genuine. I recently changed the routers, but as far as I can see, I'm not blocking traffic. (Probably should for Meross devices in the end, just for the moment, I just want things to work!). The only "non" standard thing I've done is that I've added devices to the network is to assign the MACs to the assigned addresses once they've been seen by the router so I can track them a little better and can use later to create a separate VLAN. However, I need to network my device so I can see how I'm getting my MAC, so it's not happening yet.
