TEMPer2_V4.1 Error: Unknown firmware TEMPer2_V4.1: b'808009e94e200000800109084e200000'

[UltimateSolar]

Hello, thanks for your Open Source software.

it lists nicely

/temper.py -l Bus 001 Dev 003 3553:a001 TEMPer2 ['hidraw1', 'hidraw2']

./temper.py --json []

but then

/temper.py --force 3553:a001 Bus 001 Dev 003 3553:a001 TEMPer2_V4.1 Error: Unknown firmware TEMPer2_V4.1: b'808009e94e200000800109084e200000'

PS: WHY IS IT SO HARD TO GET GNU LINUX TALK TO A THERMOMETER? (it would probably easier to build an https://duckduckgo.com/?t=ffab&q=arduino+weather+station)

Hello,

thanks for looking into it.

is this firmware check required for the values to be read?

ok now also getting the same error with Debian

how to interpret this data? :D hex_data str: 8080086c4e200000800106974e200000 (https://pcsensor.cn/ SHOULD PAY YOU FOR THIS! OR AT LEAST SHIP 100x TEMPer2)

did not fix anything:

apt-get install python3-hid
apt-get install python3-usb

You have to use the TEMPer2_V4.1 branch:

git clone https://github.com/greg-kodama/temper.git
git checkout TEMPer2_V4.1

THANKS IT WORKS! :) :+1: THANKS!

git clone https://github.com/greg-kodama/temper.git
cd temper/
git checkout TEMPer2_V4.1
git pull; # not required?
./temper.py --force 3553:a001 --json

made a little script that will write a daily log file including the time :)

vim /scripts/TEMPer2.sh
#!/bin/bash
# take meassurement with TEMPer2 USB thermometer every 3sec

LOGFILE=/scripts/$(date '+%Y-%m-%d').TEMPer2.log;
while true;
do
    printf "\n$(date '+%Y-%m-%d===%H:%M:%S')\n" | tee -a $LOGFILE;
    ./temper.py --json|tee -a $LOGFILE;
    sleep 3;
    clear;
done
