ESP8266

Board

d1mini

Component causing the issue

ccs811 and aht10

Additional information

esphome 2022.11.x was working perfectly. I had some issues with aht10 on esphome 2022.10.x, but not related to i2c connection. The sensor was going timeout after few hours while with 2022.11 I had absolute no issues.

[ssieb]

Recovery: failed, SDA is held low on the bus You didn't change anything?

[raidnet-ms]

Hi ssieb, sorry I posted the issue before completing all fields. now I edited it properly. I changed nothing, not the hardware, not the firmware. Esphome got the update automatically while yesterday I updated the firmware and suddenly I noticed sensors on i2c stopped working.

[ssieb]

Actually, this looks like it might be a general gpio issue. We're investigating.

[raidnet-ms]

Let me know if you need any test. I'm going to check if i get this problem on other hardware.

[raidnet-ms]

with scan set to false I get only errors from both sensors:

[09:26:18][E][aht10:139]: Communication with AHT10 failed! [09:26:18][W][ccs811:166]: Communication failed! Is the sensor connected?

and no scan errors of course.

[emefff]

Could it be related to https://github.com/esphome/issues/issues/3909 (change of timing)?

[ssieb]

No, that's specific to the Dallas. This appears to be a general problem with reading a gpio that switches state. i2c on 8266 is software.

[emefff]

Oh, you are right, sorry. https://github.com/esphome/esphome/commit/8fd93122545bfbc76a2e7df66a619191e66a5b10 is dallas specific, I remembered incorrectly.

[ReinhardvdBerg]

I'm also having a similar issue with i2c to a ina219 on a RP2040 Pico W, this causes the board to not start:

i2c: sda: GPIO6 scl: GPIO7

I also can't say if it worked previously because this is the first time setting it up.

[tomaspre]

I have the same issue on Pi Pico W. When I configure I2C, the board will connect to wifi, but any communication with it is not possible (even over serial), and, of course, HA won't discover/connect to the Pico. The moment I disable I2C, these problems go away. The exact same config worked fine on 2022.03 with a D1 Mini.

[raidnet-ms]

Is the d1 working with 2022.12.3?

[tomaspre]

The D1 Mini's regulator died, so I can't test that. The idea was to slowly move to Picos all around the house since ESPs and regulators are a never-ending horror story. :-(

[SteveShirvo]

Same issue here, identical logs to raidnet-ms. Has there been any solution found??

[AlpineWhite]

Bumping this.

I do not have any issues on 8266 D1 Mini V4.0 devices, but all of my ESP32s (standard wroom, s2 wrover, s2 wroom) will:

With i2c scanning enabled:

• Fail to boot
• Fail to connect to Wifi
• Get stuck in a retry/boot loop as documented above.

With I2c scanning disabled:

• Fetch one sensor value and then fail to communicate via I2C forever

[tomaspre]

Bumping too. Still the same issue on RPi Pico W, updating to the latest ESPHome release did not help.
