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 …

Will this affect other wifi devices?

No this should not affect any of your WiFi devices. IP addresses must be unique, your router/gateway should not let you create a duplicate address or use one that is currently in use. IP reservations and static addresses aren’t exactly the same thing but they perform essentially the same function, t…

Just to be clear, I don’t switch off my router at all as I tend to keep it on all the time. I only switch off and on when the matter device is offline so with my current scenario, you still recommend to specify the ip address?

Fixed / static IP addresses are always a good idea for fixed / static devices, like smart home devices… Rule of thumb: if you permanently install a WiFi device, it should get a fixed IP. (And no, not every Matter device speaks IPv6… and yes, there are ARP caches, theoretically everything should ge…

Yes, I don’t switch off my router either. The problem is that DHCP (dynamically assigned IP) devices on your router have a lease time, maybe an hour, maybe a day, depends on your router/gateway configuration. If your matter device isn’t on or active at the time the lease expires, the router/gateway…

This is what I can see. [image] I clicked on properties and can see this screen [image] Should I just click on ‘use the following ip address’ and type the address in something like 192.168.1.xxx? If yes, should I leave the subnet mask and default gateway blank? I am still thinking this is not …

This is a windows PC IP configuration. You need to make the change in your gateway/router. You don’t want to make a change here, this will not affect your matter device.

I think you are referring to this in my router config. If yes, then I have used the same ip address as assigned now. Is that ok? [image]

Ok, this looks like the correct place. You’ll have to find the device listed by mac address and click the “ON” box next to the device. You don’t have to change the last 3 digits unless you want to. I have a schema that I use for IP’s but just clicking on the ON box should create the reservation fo…

I have updated the screenshot in my previous post. What will happen if I restart my router again for some reason? I think we are almost there…
