Gardena Water Computer constantly loosing connection via Bluetooth

MrFreezeman commented 2 months ago

The problem

I have installed the Water Computer from Gardena and successfully connected it to my HA running on Intel NUC 7 with the internal Bluetooth module. Unfortunately, ever since the device looses connection constantly every few minutes. Hence, automations do not work that are set a a fixed time as coincidentally the device is not connected at that moment. What can we do? The internal Bluetooth device works perfectly with other external devices.

What version of Home Assistant Core has the issue?

2024.7.1

The same problem! After restarting home assistant and restarting the Bluetooth adapter it works again. But the problem comes back!

elupus commented 2 months ago

Likely a bluez problem, possible a driver issue with the adapter in linux. Not much we can do about that. In general we have more control over esp32.

Secondly old firmwares of the water computer are broken. Too old and it cant even be upgraded.

MrFreezeman commented 2 months ago

My firmware is 1.7.23.29. Pretty up-to-date I'd say. With that integration status it's pretty much useless then.

elupus commented 2 months ago

Run a esp32 bluetooth gateway....

tfischer4765 commented 1 month ago

I am experiencing the same behaviour and I do have two ESPhome bt proxies that should theoreticallly be in range, so the bluez issue should not affect me. The way I understand it, if the built-in adapter loses connecton for whatever reason, but one of the proxies is in range, that should take over. This, however, does not seem to happen.

Suggest you try and disable the built in adapter to see of that makes any difference.

If the built-in bluetooth module does not work reliably, isn't it possible to adjust the automation in a way that if the connection to the water computer wasn't possible to be established, the script waits for a couple of minutes to check again later?

elupus commented 1 month ago

It will check every minute or so

MrFreezeman commented 1 month ago

I don’t think so. The automation stops when there’s no connection. That’s why it doesn’t work. So, I’m wondering if I could implement a logic that waits for a couple of minutes before trying again to connect.

The connection to the device will retry multiple times before failing.

MrFreezeman commented 1 month ago

Not long enough I think.

Same issue here with ESPHome and ESP32 as bluetooth proxy. I need to restart ESP32 to bring it back to work again.

elupus commented 1 month ago

Right @DrunkenHusky . So something get messed up on the proxy if restarting it helps solve. I wonder if we can manage to ge debug logs right when it happens.

Im pretty sure its some type of disconnection failure.

DrunkenHusky commented 1 month ago

Let me know what kind of logs you need @elupus and I try to collect them :).

ambiman commented 2 weeks ago

Also happy to support here. I've the same issues with my two Gardena BT Water Controls (running the up-to-date firmware) once connected via ESP32 BT Proxy and the other via an external USB BT stick. What logs are needed?

NetFett commented 2 weeks ago

I had the same problem. Also with 2 x esp32 and 4 Gardena valves. I also tried a Shelly Bluetooth proxy. None of it helped. Then I reset the Gardena valves at their location. (Battery out, press button, battery in and wait 10 seconds until the lights all flash once. Then release the button). I also deleted the Bluetooth pairings from my mobile phone beforehand. Now it has been working for over 30 hours without any logout of the devices from Home Assistant.

elupus commented 2 weeks ago

My suspicious have always been that the devices have a limited number of paired devices and if your phone grabs one of them it can end inaccessible.

Pa. For example, my phone with official app cant access my computers once ive used them with HA.

I can‘t confirm that. I sit 1000 km away from home - only ESP32 Proxy will connect to the Gardena Devices and the Issue still exists. Worked also for me some hours in the beginnung but it will be worse as longer it runs.

NetFett commented 2 weeks ago

In my case it was actually the resetting of the valves. After that, everything was fine.
