xnd Posted April 18 Share Posted April 18 (edited) Hello Dear Shelly community, I have Shelly Pro 4PM (version 1) with some older firmware (I'm not sure what version it was) everything was working ok. LAN connection was stable, without issues (also when ECO mode enabled or disabled). Today I upgraded firmware to 1.2.2 stable and cable ETH connection stopped working. Then I tried to upgrade to latest beta (1.3.0-beta1-gd5dbd46) and this issue was still here. I have tried also restart device, enable / disable ECO mode. Disable Ethernet, restart. Enable ethernet, restart. And this issue was still here. Then I switched back to stable firmware 1.2.2. And this issue was still here. Then I did a factory reset. Issue was still here. Ethernet connection is broken. Please see my video: you can see that ETH status is most of the time disconnected but sometimes is shows correct IP address for 1 sec and then immediately shows disconnected. you can see LEDs in RJ45 are turned off and blinking in regular interval. signal-2024-04-18-133830-ezgif.com-crop-video.mp4 What I tried: switch to latest beta fw (1.3.0-beta1-gd5dbd46) switch to latest stable fw (1.2.2) factory reset ECO mode enabled ECO mode disabled Enable/disable Ethernet (and reboot) power off device, power on different LAN cables, connect to different switch and router. Ethernet configuration DHCP Ethernet configuration static IP I did "ping" command from PC to Shelly static Ethernet IP address every 1 sec. 100 attempts, 100% packet loss. I tried to set port on the switch where Shelly is conected to 100 Mbit (disable auto-negotiation) Nothing helped.

xnd Posted April 18 Author Share Posted April 18 (edited) Screen 2024-04-18 at 14.17.54.mov - also we can observe the same in shelly cloud web interface (https://control.shelly.cloud/#/home/devices/-1) - Ethernet connection is most of the time disabled and it appears for 1 second as connected. .

Administrators Olsche Posted April 18 Administrators Share Posted April 18 Maybe an IP conflict? what happens if you connect via DHCP and not with static IP? What does the debug log/diagnosis say in WEB-UI Quote Link to comment Share on other sites More sharing options...
xnd Posted April 18 Author Share Posted April 18 (edited) It started working when I set port to 10 Mbit FDX: tested on latest stable (1.2.2) and beta (1.3.0-beta1-gd5dbd46) Is that OK? Ping every 2 sec looks good: Edited April 18 by xnd Quote Link to comment Share on other sites More sharing options...
