Accessing verbose logs via web.esphome.io

Hi,

When I try to access ESPhome device logs via Home Assistant or ESPhome web_server component, I can see pretty verbose logs(logger level is set to VERY_VERBOSE). But both of these methods require ESPhome device to have working wifi connection which is not always the case.

web.esphome.io also provides a way to access logs, but it uses /dev/ttyUSB0 so it’s not dependent on wifi. Unfortunately, on web.esphome.io I see almost nothing in logs.

Can someone explain me why on web.sephome.io I see much less logs and how to change it?

Sorry if I missed something very obvious but I couldn’t find any explanation for this behavior.

I just tried this. I specified

logger:
  level: VERBOSE

in the ESPHome config, flashed it, and subsequently it does indeed show verbose output in the log on the web.esphome.io page.
