I have two routers with built-in Wireguard capability, and they are connected. The HA server is in the 192.168.10.x network, and the ESPome node is in the 192.168.20.x network. I know mDNS is not routed across, but I naively thought I could just specify the static IP address of the HA server on the …

[image] BuddyCasino: but I naively thought I could just specify the static IP address of the HA server on the ESPHome node and that would be it. It seems there is no way to do that? No, simply because a esphome node is the server and HA connects (as a client) to it. :bulb: [image] BuddyCa…

No, simply because a esphome node is the server and HA connects (as a client) to it. :bulb: But then I would expect it to work when I manually add the device via its IP? As a side-note I expect mDNS can’t cross your subnets? :twisted_rightwards_arrows: As mentioned, no. I’m not sure if its po…

Have you added the AllowedIPs on both routers? Router 1 (192.168.10.x) should have: AllowedIPs 192.168.20.0/24 Router 2 (192.168.20.x) should have: AllowedIPs 192.168.10.0/24 What that will do is add a route from router 1 to addresses in Router 2 and vice versa. Now you don’t have to route the w…

ok, I checked how I have set up my wireguard from my phone to my router. On the router I have 10.10.1.1/24 and all peers has one ip each in the same net for allowIPs 10.10.1.20/32 On the phone I have address 10.10.1.20/32 And allowedIPs 0.0.0.0/0 as all traffic will go to my VPN. Looking at …

I’ll first try if I can get rid of CGNAT and then will experiment further. Thanks for your suggestions, its been really helpful!

So I’ve changed the IP from CGNAT to a proper one, and now it seems to work. I can’t tell for sure if this is what did it, but the main takeaway is that you don’t need mDNS to add an ESPHome device, its just convenient - you can always add it manually by its IP address.

Connecting ESPHome node to Home Assistant across a Wireguard VPN

ESPHome

You should be able to make use of esphome as mDNS is not mandatory but mainly a comfort feature.

But due to the lack of logs (already requested) probably nobody will able without poking in the dark
