the reason why the greenwave node 6 responds so well is that because it is one big f… antenna. At least that is my experience as well. I have two of them and both are working as a hub for other devices before they connect to Homey.
What I do read in your post is:
still not placed all devices back
We know te zwave range of ‘pure’ homey is a bit low (but in fact it also depends on your situation…) and therefore relies heavily on some situations on the mesh network that zwave tries to create. If not all devices are replaced it could be that the devices can’t connect to each other and therefore can’t create a reliable mesh network.
For instance in my house I have a neo door sensor. This doorsensor works great by using one of the node 6 devices in between. But as soon as I disable the node 6 my door sensor is not connected anymore because it is just to weak. The distance is on a linear distance of around 5~6 meters with some thick walls, a dryer etc in between.
Another sensor, a motion sensor to be precice, doesn’t work at all at the same spot so I had to move it a bit closer to the node 6. So it is not only Homey that we can blame for the range issues but also the devices itself. Not every device has the same range.
