VLAN support

[reinos]

What's the issue?

I have the following setup: my Marstek device is on my VLAN IOT network (192.168.30.xxx), and the b2500-meter is running as a Docker container inside my main VLAN network (192.168.20.xxx).

I'm not sure how the Marstek searches for my emulated Shelly Pro 3EM, but it can't seem to find it. The Marstek can reach the IP address of the Docker container where the b2500-meter is running per firewall configuration , but it still doesn't seem to discover it.

Does anyone have experience with a VLAN setup like this?

The output of the container is

$ sudo docker compose up
[+] Running 1/1

Your setup

• Installation method: Docker
• Storage system: Venus v151
• Power meter source: Home Assistant sensor

Marstek's broadcast implementation is pretty "simplistic". AFAIK, what they do is:

1. Read own IP address
2. Replace the last segment of the IP Address with .255
3. Send a broadcast to that address

So your network setup has to ensure that any traffic going to the .255 IP address gets routed to B2500-Meter.

Thanks @tomquist

I moved it for now to the same VLAN, that did the trick. I will try to move it later back with a firewall rule, hopefully that is also working 🤞🏻
