I’ll start with I don’t have a lot of experience with Matter devices. I bought a Midea air-conditioner this summer and didn’t know it was Matter enabled. I thought I was going to add it to Google and use virtual switches to control it. To my surprise when I turned it on, ST’s announce it found a new Matter device. That’s where the trouble starts, I can get it connected, and it works for a while, it just won’t stay online. Twice now, over that past few months it just goes offline. I tried unplugging it and plugging it back in, that did nothing. If I hold down the WiFi button, ST’s sees it again and wants to add it, but I have to remove the previous offline device to get ST’s to actually complete the setup. I’m not using any routines or automations for this, it’s just a device in ST’s.
So, my question is: Are people having issues keeping Matter devices connected to ST’s? My air-conditioner is only about 15’ from the hub, and I have a bunch of ZigBee and ZWave devices in the same room, none of those are disconnecting. I know Matter devices are fairly new, but this being my first Matter device and so far, not very impressed.
Are you sure it’s not related to the WiFi network? Make sure the device has a static IP.
The only WiFi (LAN) device that is directly connected to my hub was shown as offline whenever it received a new IP.
And it doesn’t matter how far or close the device is located from the hub, because WiFi is a star topology with the router (not the hub!) in the middle.
I’ll give that a shot. It was on DHCP, so I’ve assigned it a Static address. Fingers crossed. I probably won’t buy a bunch of new Matter devices if they have to use my WiFi resources. I prefer to use ZWave of ZigBee to keep them off my LAN.
