Hello, a connexion beetween dimmer and lamp doesn't mean they are "directly connected" it mean the dimmer use the lamp as router.
Your network don't look so bad for me, just some tips.
- You realy need to have a bad connexion beetween the coordinator and the sensor for the sensor use a router instead of a direct connexion, sensor always prefer it even is a router is close to it. On my side to force connexion on a router I use some tricks, puting the sensor close the router for some hours during inclusion, ect ... , But on your screen connexions are green, so I think they are not so bad.
- Xiaomi sensor never change parent, so if you want to change the mesh, you need to re-include the device at final place.
- When using a CC2531 as router, connexions from it can be invisible, you have all connexion on your screen, but you can have invisible connexion, it's something normal, don't worry for that.
I thought a mesh network was about using the best possible signal path
Right, but I think the algoritm think a direct connexion is better than using an mediator.
BTW, on the application, you have a button called "LQI" it print some value on connexion, (but never let it, it's just for test, cpu intensive), you can compare the value beetween the sensor<>conbee and CC2531<> conbee, I m not sure but the color seem more green for the connexion beetween sensor and conbee.
But remember theses values (and color line) are just indication.
