goveebttemplogger's Issues

MRTG averaging should be an option

Perhaps with a parameter of a number of minutes, with zero being a no average, just take the last value, option.

H5181 support? (like the H5182 but only one probe)

    I have a H5181 (like the H5182 but only one probe). Can I provide raw data to help decipher the information for that model?

It actually looks like it is working but just shows the second temp as 0.

Support H5183 Meat Thermometer

I'm investigating if the meat thermometer announces temperatures or only reports via a direct connection. The announcements seem to be of two types. The H5183 was reporting 18°C when I captured these messages.

The first is interesting in its similarity to the H5177 thermometer message:

Unfortunately the H5177 temperature message is significantly different.

MRTG should return average values over last five minutes

[feature request] allow to use custom bluetooth adapter

currently the program only allows to use the first hci0 device, would be great if we could set a custom adapter using ./goveebttemplogger -i ADAPTER_NAME, where ADAPTER_NAME can be i.e. hci1 (not just hci0).

--index {filepath} \ in service config causes service to exit directly after writing index file

using release arm binary https://github.com/wcbonner/GoveeBTTempLogger/releases/tag/v2.20231001.1.

I would expect to be able to use --index within the service to automatically add new devices to my svg-dashboard.

Instead it restarts after writing the files. It is not listening.

Log V2 with --index in service config:

the index file contens is correct. After removing --index from service config, everything runs properly.

Thanks for this great tool ! - I use it on raspy 3 :-)

gvh-titlemap parsing error?

I just downloaded and built the tool on ubuntu 20.10 on a Raspberry Pi 4. If I have no gvh-titlemap.txt file in my svg folder, it runs correctly. It downloads data, it writes logs, it creates SVGs, everything's great.

I made a gvh-titlemap.txt file that contains the following 2 lines. First one is from the sample file you provide, the other is my own.

A4:C1:38:0D:3B:10       H5177 (A4:C1:38:0D:3B:10)
A4:C1:38:49:F7:5A       Humidor (A4:C1:38:49:F7:5A)

There is an extra blank line at the end of the file. I invoke the command like this:
sudo /usr/local/bin/goveebttemplogger -v 2 -l /home/paco/humidor -s /home/paco/humidor

I see this error output.

I copied your example gvh-titlemap.txt unmodified into my directory. Should be harmless (it won't have a title for my device, but that shouldn't matter, right?) I get the same result.

If I remove the file, it runs fine, but if the file is present I get this error.

Excessive CPU use on Raspberry Pi 3

Howdy!

I was trying to set up GoveeBTTempLogger on the Pi3 I am currently using as an octoprint server (to monitor my filament storage humidity), and I got everything working well, except for one problem -- it uses up a steady 20% of the pi's CPU! This seems a bit excessive, just to be able to write out a few stats to a file once a minute! And on a device that needs to be fairly responsive (due to driving real hardware), this is not ideal.

A quick trace of the process suggests that it is in a fairly tight loop of trying to read from the HCI socket, getting EAGAIN (presumably a nonblocking socket), sleeping for a very short period of time, and repeating. Quick back-of-the envelope math says it's doing this ~10000 times/second.

Is there any way GoveeBTTempLogger could be updated to either use blocking reads (with timeouts for doing things like updating graphs and such, if those features are enabled), or to poll at a much slower rate than it is currently doing? I would really like to be able to use this software!

This is using the provided .deb package, build 2.20210405-2

Thanks!

2037 dates in SVG creation

I have seen a problem on a 32 bit system where the SVG files are skewed with strange data and dates from the year 2037. that date is not written in any of the logs, just the SVG files.

Connected Download doesn't work on H5100 devices

Checking on H5179, is it supported?

Can you please confirm if GoveeBTTempLogger supports the H5179 device?

It seems like you've listed it in models, but the actual algorithm to decrypt the data is not done. Just wanted to confirm if my assumptions are correct?

Please note that the decryption algorithm is available in another project:

Failing on ubuntu 22.04 (linux mint 21) - LE Set Scan Parameters Command Disallowed

Hello,

I am facing trouble trying to make goveebttemplogger work, may be because of latest change in bluetooth stack.
The issue happens on first call of hci_le_set_scan_parameters(device_handle, 0x01, htobs(0x0012), htobs(0x0012), 0x01, 0x00, 1000)
and it is failing with error : Error: Failed to set scan parameters: Input/output error due to the action being disallowed (see btmon trace below).

On the other side I am able to complete a manual le scan with bluetoothctl on the very same host and see my Govee devices.

So to me it looks very much like this issue where bluetoothctl works but not hcitools.

It seems people recommend to do a hci_reset before see 1 & 2.
Yet I don't understand how the code should be change to have a succesfull bluetooth initialisation - I tried my own code, but it fail the same. I am completely new to bluetooth stack, so can help much more.

Regards,

Yves

Bluetooth: hci0: advertising data len corrected 31 -> 29

I'd been getting a tone of these messages in Syslog ever since I switched to the "select" method of retrieving bluetooth announcements.

The behavior appeared on both PiZeroW and Pi4 units in my home environment, but did not appear at locations in friends houses I've got the same software running. I assumed that the problem was do to something strange in my apartment wireless environment. I live in a dense apartment block with plenty of neighbors.

Systemd unit arguments are not configurable

I want to use the systemd unit but I d not want to have an SVG file. It would be nice if I could configure the systemd unit easily without needing to overwrite the entire command line

Temperature for H5075 slightly wrong

The temperature for the H5075 is not correct, but the error is less than 0.1 °C. The problem is that the humidity is included in the temperature. You can see it in the example in the code: "88ec00 03519e 64 00 Temp: 21.7502°C Temp: 71.1504°F Humidity: 50.2%"

The last three digits in the temperature (Celsius) are the same digits as in the humidity. It seems to me that the description in https://github.com/Thrilleratplay/GoveeWatcher is not correct. To get correct values I changed
"Temperature[0] = float(iTemp) / 10000.0;" to "Temperature[0] = float(iTemp/1000) / 10.0;"

Single output option flag

Background: I'm trying to control my electric smoker with a smart plug depending on the temperature of the meat probe. Getting a single reading output would be handy for this.

Question: Is there a way to program an option flag to just output the current temperature? Or maybe an array of temperatures if there are multiple probes?

Thoughts: -r (--readings) Outputs a json key-value pairs for each reading

temp values are wrong for negative temperatures

temperature and humidity data is wrong for negative temperature data ( tested using cold spray to generate - C)
Any temperature < 0 gives VERY large positive temp numbers

spend some time to figure out the 2 complement but it is not that simple.
The data for the 3bytes + 1 (3 bytes for temp and humidity split at 1000) does not lead to a simple if data > xx: data -= yy

the one with 2 bytes for temp and 2 bytes for hum is a simple 2 complement for temp (hum is never negative)

Add some ability to make filenames friendlier

Currently GoveeBTTempLogger generates files named after the devices' Bluetooth address. This makes inspecting the .log file for a particular device rather awkward if there are many devices with similar addresses. It would be nice if there were a mechanism to change the filenames.

Proposal:

1. Allow gvh-titlemap.txt to live in /usr/local/etc (possibly with a different filename, e.g. goveetemplogger-devices.conf). For backward compatibility, GoveeBTTempLogger could additionally check for gvh-titlemap.txt in the SVG output directory first.
2. Add a command-line argument (e.g. --map-filenames) to enable naming files using the mapping file. (I'd personally prefer enabling it by default, but forcing users to opt-in is okay with me for the sake of compatibility.)
3. To avoid filename collisions, the actual filenames would be of the form TITLE (ADDRESS). For example: Outside (E35ECC215C0F).{log,svg}.

If the above sounds good and if you don't foresee any major obstacles, I'm willing to try to implement it.

I had to make a couple of changes for this to work:

• remove POST_BUILD, not sure what's best practive here, but since this may be build on a computer that will not run it, this may be undesired (sudo setcap 'cap_net_raw,cap_net_admin+eip'...). In my case it failed because the build does not allow side-effects.
• install to ${CMAKE_INSTALL_PREFIX}/..

Feature Request: Push Values on to a MQTT Queue

Hi,

I'm working on a remote data logger, that logs data from my Govee sensors. I would like have the RPI put the values read at a certain interval on to a MQTT queue.

I'm not a CPP developer, so I can't implement it myself and submit a pull request for a patch.

I did look into it, though, and using the Eclipse Paho Library and a few new parameters this should be a straight forward thing to do...

Parameters

[MQTT]
MQTT_URI=myserver.athome.com  
MQTT_PORT=1883 
MQTT_Username=myMQTTuser
MQTT_Password=myMQTTpassword
MQTT_TOPIC_PREFIX=goveebttemplogger
MQTT_INTERVAL=300

The routine should then every MQTT_INTERVAL seconds send the latest reading from each device as a JSON payload to the MQTT Topic: MQTT_TOPIC_PREFIX/<<Mac Address of Device>> (or use the filename prefix used for the log files, for consistency)

JSON Payload

{
  "temperature": 23.20,
  "humidity": 43.70,
  "battery": 100
}

On the other end we can then use e.g. Home Assistant's MQTT Sensor to process the data

Example Home Assistant configuration.yaml entry

mqtt:
  sensor:
    - name: "Temperature"
      state_topic: "goveebttemplogger/gvh-A4C13876CCXX"
      suggested_display_precision: 1
      unit_of_measurement: "°C"
      value_template: "{{ value_json.temperature }}
    - name: "Humidity"
      state_topic: "goveebttemplogger/gvh-A4C13876CCXX"
      unit_of_measurement: "%"
      value_template: "{{ value_json.humidity }}"
    - name: "Battery"
      state_topic: "goveebttemplogger/gvh-A4C13876CCXX"
      unit_of_measurement: "%"
      value_template: "{{ value_json.battery }}"

(Note: This config is just a basic template, needs to be tuned to the respective HA installation)

Just a thought.....

Best regards,
Yonz

H5179?

Does this work with H5179? I'm not getting any BLE readings, so was just wondering.

Daylight savings time - not changing timestamp

I'm in the UK and the clocks went forward at the weekend.
The output from the GoveeBTTempLogger doesn't reflect the system time and is now an hour behind.
Is there a way to get the program to change the logged time according to the actual system time?

Only thing I've tried so far is to restart the service, and the output remains 1 hour behind.

Or is the time set on the device?

Is Air Pressure in the data?

The latest version of the iOS app reports dew point and air pressure. Is air pressure part of the raw data?

Define ganularity of logging

Hi.

It is great that you "save" the file only every X-Seconds to moderately "use" the SD-Card.
Nevertheless it would be great to have an option to summarize the values to a given timeframe and only log that specific value.
I am doing this currently with an SQLite Database, but collecting a lot of data to then eg. get it down to a minute base, would be more efficient to only log what I need.
e.g. 1 Minute, Average of the temperature (mayb one digit rounded), average of humidity (rounded on one digit), Battery (Min-Value)
here is my SQL Import I use for filtering it to minute base:

select strftime('%Y-%m-%d %H:%M:00',timestamp) as timestamp,'$LOCATION' as location,'$ID' as id,round(AVG(temp),2) as temp,round(AVG(humidity),2) as humidity,MIN(battery) as battery from import group by strftime('%Y-%m-%d %H:%M:00',timestamp)

Question: goveebttemplogger.service doesn't seem to accept '-c' and '--celsius'

Hey there!

I ran into the following issue today while setting everything up on my Raspberry Zero. The .svg files that are created automatically in /var/www/html don't seem to follow the '-c' argument if allpied in goveebttemplogger.service.

I tried the following:

1. "sudo systemctl edit goveebttemplogger.service" with both '--celsius' and '-c', I also tried the EXTRAARGS:

Environment="SVGARGS=--svg /var/www/html/goveebttemplogger/ --celsius --battery 8 --minmax 8 --titlemap /var/www/html/goveebttemplogger/gvh-titlemap.txt"
ExecStart=/usr/local/bin/goveebttemplogger  -v ${VERBOSITY} --log ${LOGDIR} --time ${TIME} $SVGARGS $EXTRAARGS

3. sudo systemctl restart goveebttemplogger

But the .svg files in /var/www/html/goveebttemplogger/ are still showing Fahrenheit instead of Celsius. Am I doing something wrong or can't I edit that part of the service? I can get Celsius .svg when manually starting /usr/local/bin/goveebttemplogger after all and the logs are in Celsius as well.

Thanks in advance for your help!

Log time format

Hello, first of all, I want to really thank you for this great piece of software. I needed to upgrade my grow room's environment monitoring, and I picked up 2 H5075's and 3 H5100's. So far, I only got a chance to test out one of the H5075's, but great job!

I spent all day trying to figure out why your software didn't work. bluetoothctl would see advertisements from the device, but not the logger. It turns out the signal was just too weak with that ble controller, but with another one they stream in pretty quickly.

Anyway, I just wanted to ask if it is currently possible, or in the works, to have the log written to use the client's local time. Currently I can see times relative to the local time offset. My client is in EDT (GMT -4), but logs are being written with times 4 hours in the future. Additionally, there is no indicator in the timestamp format as to which offset it is using. It's been a couple years since I messed with time conventions, but I think it might make sense to annotate this in the log format if it does not make sense to translate them before writing.

Thanks a lot!

SVG output in Celsius

is there a option to change de SVG output from Fahrenheight to Celsius?

Very new user looking to try the code out

Hello I am trying to use the templogger, and I am new to all of this.
I am trying to run this on my Raspberry pi 3B+

Started by verifying my Kernel version: 6.1.21-v7+
Then I made sure my Raspberry pi was updated and upgraded: Sudo apt update and sudo apt upgrade

Then installed libbluetooth-dev: sudo apt install bluetooth pi-bluetooth bluez blueman

Then I tried: git clone https://github.com/wcbonner/GoveeBTTempLogger.git

and: sudo apt-get install bluetooth bluez libbluetooth-dev dpkg-dev
make deb
sudo make install-deb

At this point I reread the readme and tried to verify the files were created. I was unable to find them in /var/log or /var/www/html

Thank you for putting this all together and if anyone could help me get this running I would appreciate it.

Usage questions: Custom paths and support for H5100

I'm trying to collect data from 3x H5100 but I have trouble with two points:

1. There doesn't seem to be any log / cache / svg output

goveebttemplogger \
	--verbose 1 \
	--log /root/goveebttemplogger/log \
	--time 60 \
	--svg /root/goveebttemplogger/html --battery 8 --minmax 8 \
	--cache /root/goveebttemplogger/cache \
	--download

I created and checked above dirs, but there's nothing there (/log, /html, cache), even after hours of running, and stdout like this:

[2023-11-24T22:55:12] 300 seconds or more have passed. Writing SVG Files
[2023-11-24T22:55:12] 60 seconds or more have passed. Writing LOG Files

I assume there's nothing, because nothing was found?

# just repeats from here on

I can discover the devices fine, both from the computer as well as my mobile (which I currently use to collect data). I paired one to see if it makes any difference, but it does not.

As far as I understand, these devices are supposed to broadcast the stats occasionally, but I couldn't pickup any relevant BLE data in nRF Connect on Android (unless I connect to it, and explore the services directly). Maybe there's a config I missed?

I also tried --only CC:35:34:... without any luck.

Support for H5101

I saw that there's a new H5101 device that uses the CR2450 battery with an lcd display on Amazon.

I'm guessing that its Bluetooth encoding is compatible with the other 510x devices. I don't feel like buying more thermometers right now. If someone running this software can confirm the results, I'll update the software to report the devices properly.
