BME280 Sensor Missing Inside Temp Readings

to weewx-user

I have installed the BME280 sensor and have the drivers installed. I am getting the pressure readings in the Weewx packets, but not inside humidity or temperature. Here's what the config file looks like at present:

[Bme280wx]

i2c_port = 1

i2c_address = 0x76

usUnits = US

pressureKeys = pressure

pressure_must_have = outTemp

humidityKeys = inHumidity

humidity_must_have = inTemp

temperatureKeys = inTemp

temperature_must_have = ""

Sample of syslog output:

Any thoughts on why I am not getting the inTemp or inHumidity readings in the packet output?

Hi,

Assume you are running this service? If so field inHumidity will only be added to the loop packet if field inTemp is already in the loop packet. I'm guessing here that the loop packets emitted by your WeeWX driver (eg the SDR driver) don't include the field inTemp so you are relying on the BME280 for inTemp. Since there seems to be some issues with getting the BME280 service to add the field inTemp to the loop packet this could explain the lack of inHumidity (though this does not explain why inTemp is not being populated and it is possible inHumidity is suffering from the same unknown problem). Suggest you change humidity_must_have = inTemp to humidity_must_have = "" to at least rule this cause out for inHumidity.

Also suggest you provide the output of running WeeWX directly as well as a startup log extract, this will make it easier to reconcile the loop packet contents across all WeeWX services not just in the BME280 service. You already seem to have debug = 1 in weewx.conf so leave that as is. Stop WeeWX and then run WeeWX directly. Let it run for an archive interval or two and then post the console output (LOOP: and REC: packets/records) and the log from when you started WeeWX making sure you capture the full WeeWX startup and the subsequent couple of archive intervals. Finally, could you provide a copy of your [Engine] stanza from weewx.conf.

I am running wjcarpenter service and this is the output when running WeeWX directly. By the way, it was working yesterday, but now nothing doing. Syslog output and [Engine] stanza from weewx.conf is below:

I'm afraid I know little when it comes to troubleshooting i2c issues. So running a python script to access the BME280 independent of WeeWX gives the same error. That would seem to indicate some sort of i2c issue. Sorry, not much help dealing with the latest error, you probably need an i2c experienced user.

With rtl_433 did you still have WeeWX running? Perhaps there was a zombie WeeWX process that still held the USB port used by your sdr. Have a look at the list of running WeeWX processes using something like:

$ ps -aux|grep weewx

and kill any that are still there. Then try rtl_433.

Does WeeWX run without error as a daemon if you disable the BME280 service and just run your sdr driver?

Also not an i2c expert, but a datapoint: I have a BME280 hooked up to an
ESP8266 with nodemcu, and sometimes the BME280 goes out to lunch somehow
so I stop getting reports. That leads to a watchdog reset after 15
minutes from not posting to MQTT (cleared in puback callback), but even
on reboot I don't get temp reports. Power cycling does get it working
again.

I was earlier using automatic mode. I switched to forced mode, and I
think I've had a failure since. I have hints that the problem is
provoked by power glitches and static electricity. (The ESP8266 was
powered by an old phone charger, but one that is UL listed.)

I have several other ESP8266 that have Si7021 temperature/humidity
sensors and those have been reliable, flaky power and crazy low humidity
included.

I have been thinking that my particular BME280 is damaged somehow.

So I would suggest that the OP power cycle it and see if that changes
anything.

Ok, solved the problem with remote I/O error with bme280 sensor. Found a wire had come loose. Also the rtl_sdr is back working. However, still not getting the inside temp and humidity to show in WeeWX webpage display. I do see in syslog the following packet:

Aug 7 08:31:34 raspberrypi weewxd: bme280: BME280 data compensated_reading(id=935fa750-4b08-4483-8cf3-b40b5c059717, timestamp=2021-08-07 08:31:34.908185, temp=27.590 °C, pressure=1009.86 hPa, humidity=33.17 % rH)

In weewx.conf the BME280 section has inTemp and inHumidity. Is this correct considering the packet reports temp and humidity and not inTemp and inHumidity?

[Bme280wx]

i2c_port = 1

i2c_address = 0x76

So if I understand correctly you are basically back to where you started? WeeWX runs without error but no inTemp or inHumidity data is present?

> In weewx.conf the BME280 section has inTemp and inHumidity. Is this correct considering the packet reports temp and humidity and not inTemp and inHumidity?

According to the Bme280wx readme configuration instructions you should set HumidityKeys and TemperatureKeys to the the WeeWX loop packet fields that you want the BME280 humidity and temperature data to appear. So inHumidity and inTemp are appropriate.

As for the way ahead, whilst troubleshooting I think it wise to set pressure_must_have, humidity_must_have and temperature_must_have to "", otherwise you are masking data from the BME280 and it just adds confusion/detracts from the overall picture. I suggest you make those changes to weewx.conf, stop WeeWX if it was running and then run WeeWX directly as per my earlier post. Then capture and post the LOOP:/REC: output mentioned earlier and post the log from startup. Would be helpful if the loop packet capture covers the same period as the log extract - makes it easier to reconcile the fields.

If things are still not working as they should we can put a few extra lines of code in the Bme280wx service to log a few values so we can see exactly what is going on.

Ok, here's the current section from config file:

[Engine]

# The following section specifies which services should be run and in what order.

[[Services]]

prep_services = weewx.engine.StdTimeSynch

data_services = user.bme280wx.Bme280wx,

process_services = weewx.engine.StdConvert, weewx.engine.StdCalibrate, weewx.engine.StdQC, weewx.wxservices.StdWXCalculate

xtype_services = weewx.wxxtypes.StdWXXTypes, weewx.wxxtypes.StdPressureCooker, weewx.wxxtypes.StdRainRater, weewx.wxxtypes.StdDelta

archive_services = weewx.engine.StdArchive

restful_services = weewx.restx.StdStationRegistry, weewx.restx.StdWunderground, weewx.restx.StdPWSweather, weewx.restx.StdCWOP, weewx.restx.StdWOW, weewx.restx.StdAWEKAS

report_services = weewx.engine.StdPrint, weewx.engine.StdReport

[Bme280wx]

i2c_port = 1

i2c_address = 0x76

usUnits = US

pressureKeys = pressure

pressure_must_have = ""

humidityKeys = inHumidity

humidity_must_have = ""

temperatureKeys = inTemp

temperature_must_have = ""

New problem now is that the loop apparently hangs and WeeWX quits reporting weather data.

sudo weewxd

OK. Let's put a bit more logging in bme280wx.py, we'll just look at pressure for now. Move aside your existing /usr/share/weewx/user/bme280wx.py by renaming it as bme280wx_orig.py. Download the attached bme280wx.py and save it in it's place in the /usr/share/weewx/user directory. Leave debug = 1 and restart WeeWX. Post the log including WeeWX startup and the first half dozen loop packets.

can you try this

[Bme280wx]

i2c_port = 1

i2c_address = 0x76

usUnits = US

pressureKeys = pressure

pressure_must_have = outTemp

humidityKeys = inHumidity

humidity_must_have = outTemp

temperatureKeys = inTemp

temperature_must_have = outTemp

I had a similar issue in July last year and it was discussed in these threads:

https://groups.google.com/g/weewx-user/c/-azmKGA3q_U/m/j8i9ih20BwAJ

https://groups.google.com/g/weewx-user/c/MycfgX74P1Y

The "*_must_have" lines need to contain the value of a valid sensor for the bme280 readings to be added to the loop data. In my setup I use "outTemp" from my rtlsdr in all of these lines and it works fine.

Sorry for the late follow-up. I changed the "must_have" lines to "outTemp" and all is working as expected.
