WLED integration does not find HOST

Dominicd · January 4, 2023, 10:13am

First post on the Community… so hi everyone !

I am struggling getting WLED integrated onto HA.
Here is my configuration:
HA installed on a RPi through ethernet on my main network: 192.168.1.46:8123.
WLED installed after a WIFI router and gets its DHCP address 10.0.4.33
WLED accessible from my Phone, no issue here.

if I make a ping to WLED from anywhere from any laptop connected on the WIFI router network, WLED responds positively (normal)
if I make a ping to WLED from anywhere from the main network, WLED responds positively

But when I try to add the WLED integration on HA and enter HOST, I get an error “failed to connect”

Any help will be appreciated.

PS: my router does not support mDNS.

From your ha instance can you ping the wled device?

What does traceroute say?

Thanks Nick, will investigate Traceroute: I first need to learn how to use such tool from my Rpi !

Same as ping.

This is ok, but problem is that HA installed is installed on a standalone Rpi device connected on Ethernet to my network with no keyboard, no mouse, nor display. If I hook up a keyboard+mouse+screen, can I interrupt current functionning to get access to the UI interface to launch traceroute somehow ? Sorry, I think I need some Linux training…

Install the web terminal and ssh addon.

Thanks Tom ! indeed, now I get it to work. Using traceroute suggestion from Nick, it looks like instead of staying inside my network, the wled host address traceroute goes out of somewhere !..

Looks like your fritz router needs a route set to the 10. network.

Thank you Nick. Following your advice, I created a static route that seems to work now.
I made good progress as traceroute does not show error anymore, but WLED integration still fails to connect:

If you have any idea, let me know. Thanks again.

Improvement maybe, but the traceroute does not make it as far as 10.0.4.33, it ends at 192.168.1.32.

Thank you Nick, I changed the location of the WLED with a different subnet and it works now: looks like my wifi router (EERO) is blocking the comm for the HA at one point because making a traceroute from another PC on the same subnet than where the RPi is located was working fine. Anyway: get my access to WLED now. Thanks again !
