A mesh network relies on it backing away from congested channels. On 2.4Ghz there are only 3 non overlapping channels, 1 6 11.
So in a physically congested area, like small homes next to each other, particularly narrow long plots, it’s impossible to not have congestion with the neighbours.
So say on side of the plot another router becomes busy on channel 1 well the mesh node nearest needs to move to 6 or 11 and the mesh nodes furthest away then use 1.
So mesh networks rely on no fixed channels. Mesh are needed most in congested plots and must change channels in response. So I get all of that, why a mesh network can’t be fixed to channels. Although I suspect there’s a method hidden from consumers like to test mesh nodes.
But cameras often have their own unique issues, particularly battery cameras. Often such cameras are the furthest corner in a plot, so cameras suffer worse congestion than mesh nodes which are further inward of a plot and powered.
So a mesh network can’t really help with congestion with cameras in some plots. So you’d want to manually fix a camera channel to statically avoid congestion, ideally in agreement with the neighbours on that side of the camera. I understand that background behind the ask.
I did my research, this and the fact the Eufy server is needed and just cut the network to cut the camera, meant I stuck to my own software.
