I bought a 3 pack of X55 from Amazon early this past summer, what I got was hardware ver 1.26, not 1.6, didn't have a choice thats what they sent me.

Overall I am very happy with the system and its performance, VERY FEW issues.

It last upgraded the firmware to the current build for ver 1.26 dtd 5/22/23 which included a separate IoT network feature in addition to guest network. I have a lot of wyze cameras(25) around outside my house, and other devices running on that network, they all work fine, but some keep changing from one node to another randomly, even though I have them all set to preferred connnection of just one of the nodes, depending on their location. Mesh Technology option is OFF for each IoT device as they are static and don't move. The app specifically says for each device that "This client will only connect to (specified) Deco". All 3 X55 nodes are wired backhaul with two tplink unmanaged switches between the main and the other 2. All IoT devices work fine otherwise.I will say that my house is only 1800 sq ft so 3 nodes are overkill but I wanted strongest signals for each device.

I can get them to stick temporarily to the preferred node by running the network optimization in the app but within a day or so they seem to be back to random nodes.I'm hoping the next firmware update may fix that.

Wondered if anyone else has this issue or has fixed it more permanently.

Does anyone have any idea when the next firmware update might be for X55 ver 1.26?

On a related note, what would happen if one set up 2 or more mesh nodes in the same room?? I mean, that would be silly but ideally it should work and you should be able to specify which node you would want preferred for any device connected, right?
