Gardena Bluetooth integration is continuously losing connection to Water Computer

dornadeluxe commented 3 months ago

The problem

I recently added the Gardena Bluetooth integration and added my Gardena Water Computer into Home Assistant. My Raspberry PI that runs HA is in the same room than the Water Computer so I am using the bluetooth directly off the Raspi. However unfortunatley As I can see in the Logbook the Water Computer loses its connection to HA multiple times per hour. I also had to replace the first battery in a matter of days so I do not know what is going on. What I already did: connected the Water Computer to my iPhone and did a firmware update to 1.7.23.29. Then deleted it again from the phone and did a factory reset by pressing the button, before putting in the battery. It directly connected to HA again but the problem persists.

I don't think the built-in ble in the raspberry is reliable enough sadly. Can you try a esp32 gateway?

I have the same issue with a espAtom Bluetooth proxy.

elupus commented 3 months ago

I have the same issue with a espAtom Bluetooth proxy.

And you have updated the gardena firmware. Older ones are broken.

collateral87 commented 3 months ago

1.7.13.20 is my Firmware.

elupus commented 3 months ago

1.7.13.20 is my Firmware.

Pretty sure that is broken: https://github.com/home-assistant/core/issues/103117#issuecomment-2107137994

collateral87 commented 3 months ago

I updated my firmware yesterday to vesion 1.7.13.29, what worked without issue. Since the update the watercomputer stays connected without a disconnect. I will report, when it should fail again. Thank you for your tip @elupus.

Hi, how can I update to this version. In my ha it doesn't show the availability to update... sorry.

collateral87 commented 3 months ago

I only deactivated the integration in homeassistant and connect the device with the gardena bluetooth app, update the Firmware, close the app and activate the integration again.

collateral87 commented 3 months ago

I must report that it didnt solve the problem. It happens again...

Same problem here. I got it to work for 3 weeks (have M5Stack Atom bluetooth proxy). Iwas on vacation and did no Updates. After my return at home, I made HA Update and the System restarted. After the restart of my HA 1 of my bluetooth valves is offline again.

My ESP config:

@frontside76 it is not as simple that batteries are out?

No, the valves are New: 100% battery

@frontside76 Interesting, that is duplicate of #118956

elupus commented 3 months ago

@frontside76 did you update your esp gateway too or just HA?

frontside76 commented 3 months ago

@frontside76 did you update your esp gateway too or just HA?

Both

elupus commented 3 months ago

Both

Do you happen to know what versions they were using before.

frontside76 commented 3 months ago

I had the problem with every Version. If I take out the battery and put it in again. It will work, till next time I do a restart of HA. Then one of the 3 Valves will have connection problems. Some weeks ago i also had the problem during the day, or when Backup is running. But this is fixed. So only if I restart HA, the Valve maybe thinks there is still a connection, but it is not.

If the message in the logs does not indicate a connection problem. The device is connected but giving invalid data. Lets continue this in #118956 if that error occur on a new restart of HA.

frontside76 commented 3 months ago

OK

lucaobermaier commented 2 months ago

I have the same issue - my connection broke down after changing values, the switch or random after some time. Firmware is 1.7.23.29. I have two devices right next to each other. BT transmitter is an offset Realtek BT transmitter. So no proxy is in use. Connection was only lost on one of them.

Can you please explain how you updated the device? I received mine yesterday, and its firmware is still 1.7.13.20, and no indication anywhere how to update?

Wait, nevermind, I found the Gardena App, and was able to update to 1.7.23.29, but only after I disabled the HA Integration. With that enabled, the update process would constantly break.

Install Gardena Bluetooth App
insert battery
add device to App
and then it shows that there is a new version of firmware
install firmware

thanks.

Given the fact I have a few BT proxies (Shelly 1 PM gen 3, Atom Echo, Olimex Poe), and also some connection trouble, I would love to be able to find the connecting proxy easily. Seems only the Olimex for now is close to reliable.

Suppose there is not a sensor for that connection, or some other place in HA where we find that?

love the new valve entity, not sure what the difference between the 2 is though, they toggle at the same time whenever I toggle either of them
