TO REPRODUCE

Steps to reproduce the behavior:
Upgrade from 12.3.1 to 12.4.0

EXPECTED BEHAVIOUR

A clear and concise description of what you expected to happen.
CCS811 sensor not detected after upgrade, reverting to 12.3.1 with out any other changes restores the sensor .

The driver is not in the list?? It is sensor driver number 24

Just checked the source code, see no reason why it should not be in the sensor firmware

[jlclark440]

I've since reverted back to 12.3.1 but I will reinstall 12.4 and double check on that tomorrow morning.

[sfromis]

Jason, the numbers around drivers are a bit confusing, thus:

• The list in Drivers is not I2C drivers, but various non-sensor drivers, meaning that CCS811 is not visible there.
• The list in Sensors are not I2CDriver, but I2C drivers are included, with CCS811 having number 31. Yes.
• The bits in Features can also be decoded to reveal that USE_CCS811 is included in the build. ok
• The output of Status 0 tells nothing about I2CDriver configuration, that would need to be a separate command.

[jlclark440]

I should be able to provide an update possibly later today and tomorrow morning at the latest. Assuming that all previously set values are still the same after the upgrade, I'm not quite sure what has changed. As nothing to the configuration was changed.

[sfromis]

For me, hooking a CCS811 up to Tasmota 12.4.0 worked right away, both on ESP8266 and ESP32. This test includes the same exact binary version as indicated in the Status 0 output in the initial post here.

Thx sfromis. One more time stumbled over this :-)

[jlclark440]

For what it's worth, I do have an additional device that exhibits the same behavior that may be useful for testing. I wasn't able to see any correlation between the two.

[Jason2866]

@jlclark440 Have you done more testing? We can't reproduce the problem.

[sfromis]

Since CCS811 needs more power than most sensors, like 30-54 mA due to the heater, it may be more susceptible to borderline availability of enough current on 3.3V power input.

[jlclark440]

Working on it now, have one device running 12.4.0 and the other still on 12.3.1.

12.4

10:31:39.798 MQT: stat/Nodemcu2/RESULT = {"I2CScan":"No devices found"}

12.3.1

10:31:35.835 MQT: stat/Nodemcu1/RESULT = {"I2CScan":"Device(s) found at 0x5a"}

[sfromis]

As long as you have {"I2CScan":"No devices found"}, my expectation would be that your issue is outside of Tasmota, very plausibly at the "physical level" around hardware, wiring, connections, noise and power. Tasmota can't really do anything if a device does not pop up when scanning the I2C bus for devices.

Note that in borderline cases, small variations in when how much power is drawn may tip the scale for becoming "too bad" for it to work.

[Jason2866]

Please list/describe your hardware and setup. Powers supply, used board and wiring.
A photo of the complete setup would help too.

[Jason2866]

ping @jlclark440 or can we close?

[jlclark440]

Closing, as reverting to a previous version does not exhibit this current issue.
