status_led does not light up on a failing i2c sensor

[valordk]

Operating environment/Installation (Hass.io/Docker/pip/etc.): HA installed in vmware

ESP (ESP32/ESP8266, Board/Sonoff): ESP32 WROOM 32D

The ESP32 is mounted on a custom breakout board with the required pullup resistors, capacitors and 3.3V LDO (NCP114)

Affected component: Status LED

https://esphome.io/components/status_led.htm

Description of problem: The sensor_led component which is supposed to blink on warning or error events risen from other components does not do so when an i2c sensor is diconnected.

The DUT is an ESP32D with a red LED wired to IO12 through a 10K resistor.

During the bootup, or if the wifi gets diconnected, the LED blinks as expected until the connection is reestablished., so the wiring and the basic functionality of the Status LED appears to be as expected.

But if the i2c sensors are disconnected from the board, the Status LED does not begin to blink, eventhough the i2c component starts throwing following WARNING events: [16:42:03][W][i2c:070]: Received NACK on transmit of address 0x4B

Additional information and things you've tried: As you can see from the above log, i've even forced the i2c component to log these events on an ERROR level instead of WARNING, but it did not help.

For information, the sensors begin to work fine after hot-plugging the connector back into the board.

Ahh yes... Seems to be exiting here and not calling this->status_set_warning() before

Good catch. I can try fixing it on the existing SHT3xd and the STS3x which I have pull-request for.
