No problem, Papy. 1 - check 2 - I see no problems there 3 - there can be a bad connection in a junction box for instance, but as you say at ‘4/’, about these issues occurring from the start, with random devices, it almost can’t be a power issue. 4 - see 3. Oh, I just found this post about a ´brutal’ way to heal the complete mesh in one go: > [@Report unreachable Z-wave devices](https://community.homey.app/t/report-unreachable-z-wave-devices/22493/32): > > you can do a [PTP](https://community.homey.app/t/how-to-ptp/17304). After that the complete Z-Wave mesh will be rebuild, but it takes some time. . One of the possible causes I’ve read about, can be one or more ‘chatty’ devices, which can ruin (parts of) your zwave mesh. For every device, try to set the update time of sensors as long as you find reasonable, keep away from ‘check this or that every second’ stuff. Probably interesting topic about chatty devices: > [@Homey pro 2023 - zwave too much traffic error?](https://community.homey.app/t/homey-pro-2023-zwave-too-much-traffic-error/84036/): > > I had a perfectly working homey pro 2023 with about 45 zwave devices. Since today, the zwave is not really working anymore as I get an error: "Could not send command. Too much Z-wave traffic. (TRANSMIT\_COMPLETE\_FAIL). This goes for all zwave devices now, and might be related to the latest firmware update. I have tried to reboot, reset (with back) but nothing helps. My old homey pro works perfectly, so its not the devices themselves. anyone else experienced the same? --- _[View the full topic](https://community.homey.app/t/a-way-a-script-to-automically-test-heal-devices/102883)._
