Hi All, Does anyone know why the z-wave network map page (on the developer tools) would show a device that is connected via two other devices that don’t exist. Node ID 79 is connected via 1-2-80-17-79 Node ID 2 and 80 do not exist in the map !! ![21%20pm](https://us1.discourse-cdn.com/flex025/uploads/athom/original/1X/bfa28f3636ed350830516d3f310325ce526036f4.png) ---

Not a Z-wave master 😉 but could it be that Node 79 has been added via devices that afterwards have been removed/re-added? ---

As the last known route is “Unknown” Homey just doesn’t know properly which route the last one was, things like this then might happen. I’d like to call it a glitch in the matrix. And that device probably also doesn’t work properly. ---

Strangely, that last device (79) was working fine, as its a door sensor attached to a flow to turn lights on and off, which gets used many times a day/night. ---

I did a full restart of the Homey, and its seemed to have fixed it all up. ---

Well spoke too soon, its come back again ![38%20pm](https://us1.discourse-cdn.com/flex025/uploads/athom/original/1X/2e11163368dec0e49c8544c4976fcafe0616fd44.png) Nodes 2 & 80 do not exist, no new devices have been added or removed !! The device ‘Front Door’ is actually working fine though ---

Why worry? Because of the insatiable human need to know “why” it is so 🙂
