Availability Issues with Tesla API

Configuration
1

Anybody out there who sees the same reliability issues with the Tesla integration/gateway access?

It seems to lose access to the gateway rather often, i.e. every drop to 0 in this graph marks a 30 seconds or longer disconnect - and it’ just noon :frowning_face:

Responding to myself:

I had the Tesla Gateway connected to via both, WLAN and LAN.
After I got rid of the WLAN connection, access to the API is basically at 100%.
Had to have the gateway ‘forget’ the WiFi connection - it’s still a pain that the WiFi module itself cannot be turned off properly.
