Hi for anyone interested here’s my MQTT EspHome config to load balance the TWC3 from a Shelly device: Tesla Gen 3 Wall Connector (WiFi) · Issue #20 · dracoventions/TWCManager · GitHub
and here Tesla Gen 3 Wall Connector (WiFi) · Issue #20 · dracoventions/TWCManager · GitHub to use a Shelly with HTTP
the prob with the Shelly is that it cannot handle 1s gets via HTTP, so i changed it to MQTT 1s and it works fine.
