Having issues getting a second device to respond to sACN

Hi all, does anyone here have any experience controlling LED strips from their ETC console? I've been using WLED for quite sometime in my home but recently started working on a project for a local Theatre with a few ESP32s and some WS2812B strips. I wanted to find a way to control the strips from the Theatre's lighting console (ETC GIO) and found out about WLED's ability to be controlled via sACN or Artnet, which is amazing. I managed to get one of the ESP32s to receive a signal from the console after hooking both the console and the ESP32 to the same router (console wired, esp over wifi). It worked great, but when I patch a second ESP32 in the DMX console, and set up the WLED Sync settings accordingly, I cannot for the life of me get the other ESP32s to react to the signal from the console, only the first one. I ran sACN View, which is a program that shows the sACN signals running over a network and it all looks to be working well as I can see all of the channels that the DMX Console is spitting out data on, but no dice on the WLED ESP receiving or reacting to the signal. Any ideas? Wondering if it has something to do with multicast in sACN, but can't find a spot to enable multicast in the network settings. 

  • What are the Network Settings of the 2x WLED Esps? Their IPs should be different but within the same subnet and their subnet and default gateways should be the same. 

  • Right now they both have different ip addresses, 1 has 192.168.1.101 and 2 has 192.168.1.102. I didn’t change any of the network settings on the WLED side though, just assigned the static ip through the routers settings that I have them both connected to. I’ll go ahead and try changing the default gateway and subnet in the WLED settings and see if it helps. Thanks! 

  • What Network settings does Gio have (IP, Subnet mask, and Default Gateway)? Technically sACn is sent on multicast but not sure if you have any odd managed switch settings so it might help to put all devices on the same subnet. Gio is probably set to 10.101.91.101 - so try setting your led drivers to 10.101.5.101 and 10.101.5.102 and then all devices share same subnet mask 255.255.0.0 - and default gateway IP of 10.101.1.1. 

    I also just thought - it is possible that your second driver that is not responding may have the same IP address as something else in that network so it could be possible to just change its IP to something else thats not taken amd see if its responding.

    Generally its still good to have all your devices in the same subnet because then you can ping the devices for troubleshooting.
