Operating environment/Installation (Hass.io/Docker/pip/etc.):

Python - Command line - pip esphome config/ dashboard

ESP (ESP32/ESP8266, Board/Sonoff):

platform: ESP32 board: pico32

M5Stack Atom Lite with ENV unit

ESPHome version (latest production, beta, dev branch)

v1.16.2

Affected component:

Additional information and things you've tried: Adding setup_priority does provide the same error.

I am using a AM2320 I2C Temp/Humid sensor (same as DHT12?), and could not get it to work reliably with an ESP32 until I added two 10Kohm pull-up resistors to the I2C lines.

WhistleMaster commented 3 years ago

Thanks, I will try that.

@WhistleMaster did this resolve your issue?

WhistleMaster commented 3 years ago

Unfortunately, I was not able to get a hand on those resistors, so I moved to SHT30 and BMP280 sensors.

agners commented 3 years ago

Ok, I am closing this. Feel free to reopen in case you you move back to DHT12 with external pull-up resistors and still observe the problem.
