xiaomi-ble Garden-Sensor (GCLS002) does not expose Battery SoC to the integration

[ChristophCaina]

The problem

I have several Plant-Sensors which are working nicely with the Xiaomi Integration and expose their information over Bluetooth (device: HHCCJCY01) ... with Firmware version 3.2.6

I also have a large "Garden-Sensor" - device GCLS002 with Firmware 3.3.6 It can be charged per USB cable, comes with a fixed battery... I can see, that the battery SoC will be shown in the FlowerCare app, but it isn't available within the Xiaomi integration of HomeAssistant.

Any steps I can do to provide required information to implement the Battery Sensor for this device?

What version of Home Assistant Core has the issue?

2024.2.0

What was the last working version of Home Assistant Core?

Hey there @jc2k, @ernst79, mind taking a look at this issue as it has been labeled with an integration (xiaomi_ble) you are listed as a code owner for? Thanks!

Code owner commands

Code owners of `xiaomi_ble` can trigger bot actions by commenting: - `@home-assistant close` Closes the issue. - `@home-assistant rename Awesome new title` Renames the issue. - `@home-assistant reopen` Reopen the issue. - `@home-assistant unassign xiaomi_ble` Removes the current integration label and assignees on the issue, add the integration domain after the command. - `@home-assistant add-label needs-more-information` Add a label (needs-more-information, problem in dependency, problem in custom component) to the issue. - `@home-assistant remove-label needs-more-information` Remove a label (needs-more-information, problem in dependency, problem in custom component) on the issue.

I am also having this problem. Not a huge deal but would be awesome if there's a way to fix this.

Would love to have battery stats as well. This device is also known as Xiaomi Flower Care Max (HHCCJCY09)

[Ernst79]

In BLE monitor, I didn't find battery data in the passive BLE advertisements. It might be available by connecting to the device, similar as we now do for the other plant sensor.

Let me know how I can assist :)

[hapklaar]

@Ernst79 anything we can do or test to expedite this?

[Ernst79]

I'm not familiar with setting up connections to BLE devices. I know there is some code already in xiaomi BLE to get the battery state for the other plant sensor. But I don't have the time and skills to add this, Hopefully someone else can help.

Hi,

I was going through the HA Logs for another issue, and found this information. I don't know, if this is helpful or not, but... maybe.... ?

And many others with the same payload but different FnCnt ...

This needs to be done in Bluetooth-Devices/xiaomi-ble, I can probably create a PR over there.

[Rickth64]

See Bluetooth-Devices/xiaomi-ble#79

[Ernst79]

Released as 0.30.0 in xiaomi-ble

[ChristophCaina]

Released as 0.30.0 in xiaomi-ble

So, now ha needs to use 0.30.0 of the library, right?

[Ernst79]

Yep

[hmmbob]

Just a short message confirming that 0.30.0 fixes the issue:

It'll very likely be part of 2024.7, given the time of the merge (I patched my running container to use 0.30.0 for testing)

[hapklaar]

Curious, did it make 2024.7? Just updated, but see no battery stat yet.

[ChristophCaina]

yes, it did and it is working (except, my bt proxy has issues with the traffic...)

It might take some time, until the new sensor will be added.
