Communication with HTU21D failed!

Tonguc-Endem commented 1 year ago

The problem

I know the same issue was submitted before but I'm 100% sure that this is a new issue.

This started happening on two separate devices after updating to the latest firmware. They were functioning perfectly fine until I hit update on each of these devices which have been showing "UPDATE AVAILABE" for some time.

I have tried reversing GPIO2 and GPIO0, tried 100KHz frequency, tried a different HTU21D module, tried a different power supply, checked connections, basicaly everything you can think of.

The important thing is that they worked until the update.

The following is from an ESP01:

While debugging a similar issue using multiple sensors (Si7021==HTU21D and BME280) on a single I2C bus I've noticed that the first sensor defined in the config fails every time while next ones work without issues, regardless of their types, adresses etc. I've worked around it by defining a dummy 'sacrificial' sensor as the first one - could you try this?

1danielsan commented 1 year ago

Hello, could you help me with the code? How do you define a dummy sensor as the first one? could you please write me an example? thank you very much!

I will give it a try but would appreciate your example scrificial lamb : tried this: `sensor:

I've simply added an additional sensor with another address, something like this:

sensor:
  - platform: htu21d
    address: 0x39
    temperature:
      name: ${upper_devicename} dummy temp
    humidity:
      name: ${upper_devicename} dummy humidity
  - platform: htu21d
    address: 0x40
    temperature:
      name: ${upper_devicename} valid temp
    humidity:
      name: ${upper_devicename} valid humidity

However, in case of DoerakkerHA, the part with

[09:41:51][I][i2c.arduino:070]: Found no i2c devices!

tells me that you most probably have a connectivity problem - either swapped pins, some broken wire or possibly too weak pullups; for me the automatic I2C scan always showed valid addresses if connected correctly. Additionally, I see you're explicitly configuring I2C ID for the sensors - what's your I2C bus config?

DoerakkerHA commented 1 year ago

i2c: i2c_component

The ONLY change made was to change OS from Tasmota to Esphome. The actually heater where this is physically installed was not touched or changed in any other way

mjbogusz commented 1 year ago

it should be something like:

i2c:
  - id: i2c_component

(reference)

Also try setting the pins (sda and scl) in the i2c config manually/explicitly - it is possible that the board config you've selected defaults to other values than your Tasmota config. For testing purposes you can lower the frequency to 10kHz as well, it may help if the line is noisy (again, Tasmota may default to lower frequencies and/or have better error handling).

DoerakkerHA commented 1 year ago

Thanks I will try it later. Just to rule out I didn't loose my marbles I just OTA Tasmota sensors back on it:

Stumbled across some posts relating to this issue. It turns out it is not a i2c device but a semi MCU -> 1wire solution from sonoff to make the Si7021 compatible with their TH10/16 series and AM2031 sensor package

Now I know that the discovery has been (via the TH21d.h package) looked into. I guess that was work done for Tasmota

So it is not a i2c issue but from here I have no idea where to look next

1danielsan commented 1 year ago

Today I Updated esphome to the latest 2022.11.5 version. recompiled and upload the code. SAME ISSUE. no sensor found....

NikonNLG commented 1 year ago

Same for me for a years. HTU21D works correctly on ESP8266, but failed on ESP32 very often without any reasons. It doesn't depend from count of connected devices, pins (I tried to choose different). In verbose mode it looks like this:

[23:04:13][VV][i2c.arduino:140]: 0x40 TX F3
[23:04:13][VV][i2c.arduino:116]: 0x40 RX 6850

[23:04:13][V][component:201]: Components should block for at most 20-30ms.

But SOMETIMES it start to work, without touching any wires or something like that. I'm confused how to reproduce bug

If someone have same issue: It start work with 2.2kOhm resistors on SDA/SCL. Still not sure why HTU21D work on ESP8266 without resistors.
