2 years ago That was a problem:
get CPU usage
def get_cpu_usage(): cpu_usage = str(os.popen("top -n1 | awk '/Cpu(s):/ {print $2}'").readline().strip()) return float(cpu_usage)
When I commented on this, the telemetry transmission works. so something wrong in the definition of reading CPU.
In RAW DATA and Overview - no telemetry data.
In RaspberryPi it only displays:
pi@raspberrypi:~ $ cd client pi@raspberrypi:~/client $ source ./.venv/bin/activate (04_iot_central) pi@raspberrypi:~/client $ python raspberry_pi_client.py Press Q to quit Sending reported property: {'remaining_disk_space': '19G'}
Errors are displayed when the program is interrupted by Q.

Please, can you tell me where this error came from ? "line 91, in get_cpu_usage return float(cpu_usage)** ValueError: could not convert string to float: ''"
About, Commands - works ok.
