I have a few Meross plugs, which seem to have been working fine with Alexa (with the odd lost of contact requiring it to be redicovered). I’m now trying to integrate these into HA (I’m very much a 2 day novice), and using the ‘Meross LAN’ addon (still using the Meross Cloud) it seemed to be going well.
However, I find that the devices frequently lose contact, and investigating on my network this seems to be because the MAC address changes … I can see this both at my router and with ‘nmap’. The manufacturer (OUI?) first 3 hex numbers are either: 48:E1:E9 (Meross), or 2A:EE:52 (locally generated??). The last three hex numbers remain constant.
Has anyone else observed this behaviour, and if so, how do you deal with it, since I thought that the MAC address forms part of the UUID ID of the device.
