Basic Inquiry Not Working

[cxvoth]

Hi, I'm eager to get the Aranet4 integrated into Home Assistant and I found this project that would be perfect.

My Aranet4 device works properly, and the mobile app functions as expected. The device firmware is reported as v0.4.10. "Smart Home" integration is enabled in the mobile app.

aranetctl in installed on Ubuntu 22.04 using Python 3.10 Looks like pip installed version 2.1.3 of Aranet4-Python

ananetctl scan works as expected. I assume the sensor details are not returned during the scan because of the old firmware version.

./aranetctl --scan
Looking for Aranet4 devices...
=======================================
  Name:     Aranet4 12ED5
  Address:  EF:BE:2D:BA:DD:A5
  RSSI:     -43 dBm

However, any attempt to query the device directly never returns a result: ./aranetctl EF:BE:2D:BA:DD:A5 (blocks forever)

I have tried multiple variations with the device paired and unpaired with the mobile phone and computer. Unfortunately the mobile app will not allow me to update the firmware due to "unable to reach firmware service..."

Any ideas?

Have you enabled "Smart Home Integrations" in Aranet4 app?

yes

Did some tests with both v1.2.0 and 0.4.1 firmware on Linux (Raspberry Pi 4). Blocking only occurred when Aranet4 was not paired to system.

Thanks for verifying. I focused on ensuring the device was properly pairing: Success.
