[weewx-user] Re: Acurite 01536 (Costco) pressure sensor

[David Morgan]

Note from the datasheet that it measures both pressure and temperature, and 
has correction constants built in, but correction must be applied 
externally.

I have been looking I photos I took of the main board.   I now see that it 
uses a 24C512 EEPROM.   Right next to it appears to be the barometric 
pressure sensor.  Photo is not good enough to read the part number.   Also, 
I believe the humidity and temp sensors are on long leads, and stick out to 
where they are close to the air opening in the upper left side of the unit 
as you look at it from the front.

I did take the console apart last night to see what parts were used.   I 
found the ICs were covered over with a hard black coating so you cannot 
identify what is there.  I did not find anything that looked like pressure 
sensor.   I did find what is probably the temp sensor.

I am finding that with my laptop, connecting to the console is not 
consistent.  Once connected, it seems to do OK.  I am not a programmer, so 
understanding the python code is not so easy for me.   Makes it hard to 
understand just where things are not working.  Wireshark is showing the 
system is having trouble initiating the transfer of data from the console 
to the host, even though it has already read the initialization data from 
the console.  Below is a dump from wireshark.   

Frame 595, the host issues a   USB   SET INTERFACE Request
Frame 596, the console responds,   USB   SET INTERFACE Response  :: URB 
status: Protocol error (-EPROTO) (-71)
Frame 597, the host issues a   USBHID GET_REPORT Request
Frame 598, the console responds,   USBHID GET_REPORT Response :: URB 
status: Success (0)   Console responded with 10 data bytes.

All following messages were successful.   So why did it just start working? 
 And why was the data request successful when the set interface request 
failed?  Is it not necessary for the USB interface to be set before a 
USBHID request?  Who sent the USB request?  Was it Python or the linux 
kernel?  These are things I have not figured out.

there are a few threads in this forum, as well as the weewx-development 
forum, about sniffing usb, serial, or network traffic in order to figure 
out what the hardware is doing.

the protocol for the acurite hardware is pretty straightforward - the 
trickiest part was figuring out the temperature/pressure encoding, but 
george cracked that one when he found the spec sheet for the HP03S sensor 
they were using.  then it took awhile to figure out the firmware bugs and 
hardware variants after the initial 01035/01036 models.

if you want to hack on your station, you might try to make reading of 
history records reliable (the R3 messages).  acurite consoles do not have 
much memory, and it is rather pointless for older hardware, but could be 
useful for newer hardware that defaults to having usb comms enabled after 
power cycling.

take a look at the comments in the driver file, acurite.py

it explains pretty much everything we know about acurite hardware, 
including the reason for the console barometer readings.

other driver files contain similar information about their respective 
hardware.

there have been many contributions from many different people!

weeks in setting it up.  I tried weewx first on my Toshiba L355, not

I tried installing with the deb package and from the Mint repository both. 
 I did get to the input screen a couple of times, was not sure what to use 
for the model number as it is not listed as supported.   Decided to try it 
on my wifes laptop, a Lenovo, running Mint 17.x or 18.  It worked just 
fine.  Came back to my computer, finally got it running.  Don't know why, 
it seems to have a hard time getting started.  I plan to do more looking at 
that.  I modified acurite.py a little for debugging.  After getting it 
running, I found I can use Wireshark to look at the serial interface (after 
enabling a kernel module), would have been nice to know that earlier.

The barometric pressure is way wrong on the console, and there is some 
disagreement between the console and the WeeWx display. I am curious if 
anyone knows yet what sensors are used.  I have resisted peeking so far, 
but  that may change.  I will admit to being older, and getting confused 
about what I entered where in getting this going.  But it has been fun, and 
interesting poking through the Python code to add a couple of debugging 
outputs to the log file.

Thanks Marcus.  I finally got mine working today.

I agree.  Power from USB should have been standard.

I'm using a raspberry pi 2. I did hack together a USB cable power combo and
power the unit from that. Why they don't take power over USB out of the box
is beyond me...

What hardware are you using for your AcuRite 01536?  I have tried using a

 Marcus,

 I have been running one of these units with weewx on a RPI3 since mid
 October.  The console is telling me the log is full and to connect it to
 the PC to clear it out.  It has been telling me that since 12 days after I
 set it up.  But it still works fine with weewx.  From what I can tell, the
 Acurite 01536 is based on the 02064 but is specific to Costco and has a

 One difference from the docs is there's no 'USB Mode' switch on this 
 base, so I'm interested to see if the log fills up over time.

 The only real 'issue' is the barometer reads outside the values allowed 
 by weewx by default. I'm also seeing values vary by quite a bit, but it's 
 super windy out right now. I added an adjustment to match the display, 
 we'll see how it lines up over time.

 Does anyone know if the display reports barometer or pressure?

 All in all, seems to be working great.

wind speed and direction work for me.  In weewx no direction is shown if 
speed is zero.  You getting speed and direction on the console?

I got the same unit from Costco and I have been able to get it to work with 
weewx; however, I am not getting wind speed and direction.
Is that working for you?

1536 on the left and 2064 on the right.  The consoles lock up after 6 or so 
months of operation.  This year going to hard reset

both consoles at the end of the year, so maybe the rain total will remain 
correct for at least the spring rain season.  When I get time to get one of 
the bmp sensors working with the SDR Pi, there will no longer be a USB 
connection to the 2064.  Maybe the console will have better uptime.  Or 
maybe an option like "wee_database --update-acurite-console"  :)

Marcus,

I have been running one of these units with weewx on a RPI3 since mid 
October.  The console is telling me the log is full and to connect it to 
the PC to clear it out.  It has been telling me that since 12 days after I 
set it up.  But it still works fine with weewx.  From what I can tell, the 
Acurite 01536 is based on the 02064 but is specific to Costco and has a 
slightly different screen layout.

Thanks
Scott

marcus,

the 01035/01036 consoles are the older models and have 4 usb modes.  
apparently acurite got rid of the usb modes with the 02064 (replacement for 
the problematic 02032), and now with the 01535 (replacements for the 
01035/01036?).

be glad that you have a console with no usb mode - the ones with usb mode 
default to mode 2 (no comms), so if you ever get a power failure with one 
of those you must manually punch buttons before you get data again.

the 5-in-1 reports station pressure, then the console applies some 
algorithm to get barometric pressure.  weewx just uses the value directly 
from the sensor.  apparently acurite's algorithm can take up to 2 weeks to 
settle down.  take a look at the comments in bin/weewx/drivers/acurite.py 
for more details.
