Hi My Homey Pro started having zwave issues a week ago, a lot of devices were turned on, but app recived the TRANSMIT\_NO\_ACK. And now the issue has gotten alot worse. I no longer am able to control devices, I tried to start Homey in recovery mode, did a full download, and keep user data, but still the same. The Heal button does nothing, the Test button states that the device is offline. I have devices that are within 5 meters away, they are all non responsive. It is also listed some dead devices in the routing table, like number 4 here, but I have read that that dows not mean anything (or does it ? ) See attached screenshot… Any tips as to where to begin ? A month ago I had a simmilar issue with all my Zigbee devices, and that just suddenly started working again… ![Skjermbilde 2022-03-18 kl. 16.25.23](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/e/9/e94d3221fd962dfc4301b0f388bec115a0e0b705.png) ---

Have you already replaced your Homey’s power supply? ---

Well yes, but I can try yet another actually. I tried that the first time I had issues, but they were not resolved by that, ---
