Hi there since e.g. 2 months Homey is having trouble reaching zwave devices. I use only Qubino devices. The Zwave devices are all located within 60CM from the Homey. And I have 4 qubino devices 2 floors down (but works for 2 years).

Well I have added some screenshots, from APP and from developer tools zwave.

You can see 1 is unreachable, some others (from downstairs, 2 floors aways from Homey) are sometimes not reachnable, and other moments they are. App says trasmit\_complete\_no\_ack

I have nothing changed, I did not bring in any other wireless devices…

I have motion sensors to put on lights e.g in toilet, but if the dimmer is unreachable - no lights go on. THat’s not really what my family members want.

Any idea how to troubleshoot?
