Home Assistant HACS getting error from victron-ble #61

Open kencraw opened 1 month ago

kencraw commented 1 month ago

Describe the bug Home Assistant is not able to read the output of my SmartSolar MPPT controller. Installation of HACS and Victron-BLE went fine. HA discovers the SmartSolar device automatically. But when it shows up in the list of devices as "SmartSolar HQ22394J2HQ" the 2nd line says "No devices or entities"

The one thing I may have misconfigured is the "Advertising Key" as there seems to be a terminlogy inconsistency. Using my Android VictronConnect app I followed the directions on the main page (https://github.com/keshavdv/victron-ble) and got to the "Instant Readout Encryption" screen. I checked that the Mac Address matched with the discovered device in HA was showing and then typed in the provided "Encryption Key" into the "Advertisement Key" on HA. It seems like that it what I should do, but since the terms don't match I wanted to make clear this is how I configured it.

Steps to reproduce:

  1. Install HACS and Victron-BLE on HA
  2. Go to HA -> Settings -> 'Devices & Services'
  3. In the 'Discovered' section, click the 'Configure' button
  4. Review the name and address in the Pop-Up window match the device
  5. Enter the "Encryption Key" from the Android app (as described above) into the "Advertisement Key" box.
  6. Click Submit
  7. Click Finish on box indicating successful setup
  8. In HA enable Debug Logging for Victron BLE
  9. Go to HA -> Settings -> System -> Logs
  10. Click on "Unexpected error updagting SmartSolar HQ22394J2HQ data" entry under "Home Assistant Core" section
  11. Copy error text
