Should I remove the previous docker versions?
I’m not sure what you mean. Are you referring to the prompt to prune previous images during update? you can select “yes” there.
That is what I meant. It updated.
It looks like you still have to flash the firmware (
Yes, the sensors are recognized by their unique address, not where you plug them in.
Using the UI I get the following, tried that twice.
Update failed: Request failed with status code 424
If the retry fails, run
Started updating spark-one@/dev/ttyACM0 to version a641578b (2020-09-22 22:47:58 +0200)
Sending update command to controller
Waiting for normal connection to close
Connecting to /dev/ttyACM0
Failed to update firmware: SerialException([Errno 6] could not open port /dev/ttyACM0: [Errno 6] No such device or address: ‘/dev/ttyACM0’)
Scheduling service reboot
So I did
$ brewblox-ctl flash
Your firmware has been updated.
If a new bootloader is required, your Spark will automatically download it over WiFi.
ONLY If your Spark LED keeps blinking blue, run: ‘brewblox-ctl particle -c flash-bootloader’
The light is blinking blue and the screen is blank. so I ran the
$ brewblox-ctl particle -c flash-bootloader command.

I am now waiting to see if the UI loads again. Is there a way to set it to auto update? Maybe some cron job?

The UI does auto-update, but you do need to restart your services (
brewblox-ctl up) after flashing the controller with a brewblox-ctl command.
If it’s unclear whether services are active, you can run
pi@raspberrypi:~/brewblox $ brewblox-ctl up

Seems that it is all in order now. I created a new log just now but it might be a bit too soon to diagnose anything.
You may want to run
brewblox-ctl disable-ipv6 if you haven’t already, but otherwise everything looks connected and ok.
Yes looks like it was already disabled.

Do you still have issues with accessing SSH on your Pi?
Connection status / logs look ok, with the exception of voltage reported by your Spark.
It still reports 9V on the 5V power supply.
What is the output of the
vcgencmd measure_volts command?
How is your Spark powered? (through the Pi, own adapter, from voltage?)
It is powered by the pi itself.
$ uname -a
Linux raspberrypi 5.4.51-v7+ #1333 SMP Mon Aug 10 16:45:19 BST 2020 armv7l GNU/Linux
Does the gap start when you started updating your system, or before that?
Edit: we also discussed the strange reading on your voltage sensor. The most likely explanation is that it’s a firmware bug. If your Spark otherwise works as expected, then don’t worry about it.
Can you tell me what the memory percentages are on the top right of the display?
Can you export your blocks from the service page of the spark? (top right menu).
Can you dump your eeprom so I can get an exact copy of your spark (
brewblox-ctl particle -c eeprom).
The 5V supply voltage being read as 9V puzzles me.
The value is provided by the touch screen chip, which reads its internal supply voltage. With power only coming from USB, it makes no sense that a higher voltage is read. This leaves 2 options:
- A hardware problem, but I cannot think of one yet that would give symptoms like this.
- A software bug, most likely something memory related.
It starts more or less at the same time, not completely sure. I updated on Friday and that is when it stopped recording so it would make sense.

Hope this helps!
You are only using this to monitor a few temperatures.
You are hardly using any memory and the Spark is not doing much at all. That rules out many software bugs.
I think the gap in data is indeed that the system was not brought back up after updating.
After doing the above I lost the interface while still being connected via SSH. I remember
$ brewblox-ctl up is is now up again. here is
$ brewblox-ctl log https://termbin.com/9kyjh
Yes, for the eeprom dump command we take down the normal services, so you had to start them back up.
