Shelly integration does not support devices connected via Shelly range extenders

[tempesta-home]

The problem

I'm trying the new feature "Range Extender" of the shelly Pro and Plus series.
You can connect Shelly devices through other Shelly devices, but the result is that you can have one IP address (the shelly device that acts as gateway/proxy) that maps on many shelly devices on different ports.
The Shelly App works regularly.
When you try to connect HA Shelly integration with an IP:Port pattern the result is: "Unexpected Error"

Unexpected exception
Traceback (most recent call last):
  File "/usr/local/lib/python3.10/site-packages/aioshelly/common.py", line 52, in process_ip_or_options

During handling of the above exception, another exception occurred:

Hey there @balloob, @bieniu, @thecode, @chemelli74, mind taking a look at this issue as it has been labeled with an integration (shelly) you are listed as a code owner for? Thanks!

Shelly integration does not support this feature, we currently have other Shelly features with higher priority that are already in work so I can't update on a timeline for that.

Ran into the same problem. Although, the shelly "Range Extender" feature is still in BETA, it seems to work quite promising. According to @thecode, the feature won't be supported within the near future. Therefore I was giving it a shot to work-around the issue.

1. Enable "Range Extender" feature on primary shelly
2. Connect secondary shelly to primary shelly
3. Secondary shelly should be available at "primary-ip:port" (eg. 10.0.0.1:8002)
4. Set up a "proxy" that forwards http/websocket requests to that url (10.0.0.1:8002)

In my case I've used apache2 with "mod_proxy, mod_proxy_http and mod_proxy_wstunnel" to handle the requests.

<VirtualHost 10.0.0.2:80>
    ProxyRequests Off
    ProxyPreserveHost On

    RewriteEngine On
    RewriteCond %{HTTP:Connection} Upgrade [NC]
    RewriteCond %{HTTP:Upgrade} websocket [NC]
    RewriteRule /(.*) ws://10.0.0.1:8002/$1  [P,L]

    ProxyPass / http://10.0.0.1:8002/ retry=1
    ProxyPassReverse / http://10.0.0.1:8002/
</VirtualHost>

All requests to 10.0.0.2 will be forwarded to 10.0.0.1:8002 (secondary shelly) and it's possible to be used within home-assistant. Unfortunately, this is nothing more that a proof-of-concept.

I would love this feature! I would like to add a "Shelly 3EM" next to my "Pro 4PM" and share the "4PMs" ethernet connection to the 3EM with this "Range Extender" feature.
