Gardena AquaPrecise not discovered via Bluetooth integration although advertisements are detected

Home Assistant version

  • Core: 2026.6.1
  • Supervisor: 2026.05.1
  • Home Assistant OS: 17.3
  • Installation: Home Assistant OS running as VM on Proxmox

Bluetooth setup

  • ESPHome Bluetooth Proxy
  • ESP32 DevKit V1
  • ESPHome configuration:
esp32_ble_tracker:
  scan_parameters:
    active: true

bluetooth_proxy:
  active: true

Device

  • Gardena AquaPrecise
  • Art.No. 16000
  • Firmware: 1.1.5.0

Problem

When adding the "Gardena Bluetooth" integration, Home Assistant searches for approximately 15 seconds and then reports:

No devices found on the network

The AquaPrecise is never offered for configuration.

Important observation

The device was discovered once via Home Assistant Bluetooth auto-discovery during earlier testing.

A configuration dialog appeared, but the setup did not complete successfully.

Since then, the device has never been offered again through auto-discovery and cannot be found through manual setup either.

Observations

Bluetooth diagnostics clearly show the AquaPrecise:

  • Name: AquaPrecise
  • Address: EB:DD:A8:5D:XX:XX
  • RSSI: approx. -60 dBm
  • Connectable: true
  • Service UUID detected:
    98bd0001-xxxx-xxxx-xxxx-xxxxxxxxxxxx

Bluetooth debug logs show a successful match:

match: {'husqvarna_automower_ble', 'gardena_bluetooth'}

Home Assistant therefore correctly identifies the device as a Gardena Bluetooth device.

Additional observations

Bluetooth diagnostics show:

connect_completed_total: 0
connect_failed_total: 0

No connection attempt is ever initiated by Home Assistant, even though:

  • the device is connectable
  • the Bluetooth proxy supports connections
  • free connection slots are available

Verification

The official Gardena mobile app can still connect to the AquaPrecise successfully (takes about 8-10 seconds).

Therefore:

  • Bluetooth communication of the device is working
  • The device is operational
  • The issue appears to occur between discovery and configuration flow inside Home Assistant

Diagnostics

Bluetooth diagnostics and logs available upon request.

Have you checked that it is not ignored or disabled?

Have you put the AquaPrecise into pairing mode?

@fleskefjes Yes, of course I did, but unfortunately there was no Device showing up. As I initially posted, it came up once. I clicked on Add but it stopped with an error message, not really an error message more likely a note. Could not add device...or something like that. Since then I tried everything that this will show up again. but it didn´t.

@blueJack92 Yes I did. the blue LED was flashing, my ESP32 with BLE BT-proxy also sees the Aqua precise, as you can see in my explanation. What wonders me is that connect_completed_total: 0
connect_failed_total: 0
When I try to add an integration I search for Gardena Bluetooth and it starts with the note: Starting Bluetooth application, please wait a moment, and after roughly 15s it ends with the note: no device found. And that´s it. It´s really annoying

Hi again,

is there any chance to get this solved? As other users are getting their device connected to HomeAssistant. Any idea, how to get [quote="Rittermini, post:1, topic:1013139"]

connect_completed_total: 0
connect_failed_total: 0

[/quote]

this thing changed? So that HA IS trying to connect. So it seems to me when trying to get Gardena Bluetooth integration added, and the dialog appears "Gardena is trying to find bluetooth devices..." (or something like that) that this event probably is not successfull. But I´ve got no idea how to check that in a log-file or whatever. So if someone has got an idea, please share.....
Thank you very much!!

Kind regards Thorsten
