Component dallasng took a long time for an operation

[Masterz69]

Have 3 sensors connected to ESP32.

esp32:
  board: esp32dev

Getting following messages instantly.

[11:37:18][W][component:204]: Component dallasng took a long time for an operation (0.16 s).
[11:37:18][W][component:205]: Components should block for at most 20-30ms.

On other hands ESP8266 with 6 sensors have no messages in log.

esp8266:
  board: esp_wroom_02

If can help to investigate case why more powewrfull board spend more time on reading less sensors - just let me know.

I see the same error, with only one Dallas sensor on my device. It is a Sonoff TH Elite, with a DS18B20 sensor. No modifications done, except that it now runs ESPHome.

I switched recently to this component after I started getting scratchpad errors with the built-in Dallas component in ESPHome.
It is running the Thermostat Climate component, using the dallas sensor for temperature.

esp32:
  board: nodemcu-32s

external_components:
  - source: github://nrandell/dallasng

dallasng:
  pin: GPIO25
  update_interval: 15s

sensor:
  - platform: dallasng
    name: "Temperature"
    id: "dallas_temperature"

This is what is logged for each cycle:

Similar issue observed here.
Using standard dallas I get scratchpad errors on first read, and I get took too long errors.
With dallasng I no longer get scratchpad errors, but with a single sensor from adafruit advertised as "tested" authentic I get occasional took too long error.
