In my home setup, I have 8 acccess points (not really a mesh setup, as all my APs are wired to a central switch connected to the internet router)
I have configured two SSIDs in each AP: one of them is the same for all APs (MyHome) while the other one is unique to each AP (Garage, Kitchen, Garden, …)
I have configured each Tuya device to connect to the specific SSID of the nearest AP. Other devices which can move around the house (phones, computers, tablets, robot vacuum, etc) use the common SSID (MyHome)
If your mesh system allows for something like this, it is a solution to avoid devices connecting to a distant AP.
