Communication with HTU21D failed! #926

Closed Limych closed 3 years ago

Limych commented 4 years ago

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

Docker installation

ESP (ESP32/ESP8266, Board/Sonoff):

NodeMCU ESP32

Affected component:

HTU21D

Description of problem: Communication with the HTU21D is not established after OTA firmware. After pressing the Reset button, the sensor works fine for a while. But then again it stops transmitting data to HA.

Additional information and things you've tried:

OttoWinter commented 4 years ago

That happens if a soft-reset of the HTU21D fails at startup.

Please try with a minimal config and all other devices off the i2c bus.

Limych commented 4 years ago

I already made a version with automatic soft reset via the reset switch in case of a sensor “freezing”. This did not help.

I'll try to do it with a minimal config.

Limych commented 4 years ago

The error disappeared when I removed the second i2c bus from the configs. And it returned back when adding another sensor to the same (only in the config) bus. At the same time, when the config returned to the state "one bus + only htu21d", the error did not disappear again. It turns out that, in a strange way, it does not always depend on configs.

mkono87 commented 4 years ago

Im having this same problem with the same sensor. Its been working for weeks then just started doing this. Im suspecting the sensor has died??

stale[bot] commented 3 years ago

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

freynder commented 3 years ago

I had the same problem with this sensor. I set "scan: False" on the i2c interface and manually added the address:

platform: htu21d
id: htu_sensor
address: 0x40

which seems to work ok now.

prchal commented 3 years ago

The same with 2 boards and sesors - both esp32. On 8266 works well. scan: false, address: 0x40 didn't help.

chrismetcalf commented 3 years ago

I'm getting this issue too. Brand new ESP32 and sensor. 1.19-dev.

chrismetcalf commented 3 years ago

Hard coding the address doesn't help either.

Tried upgrading to 1.20.3 and I get the same error.

Tozzi89 commented 2 years ago

I have the same issue, everything is brand new, and the config is very minimal. I have tried some of the tips in this thread but nothing works. I have managed to get it working only once when I pressed reset button on the esp32.
