Thank you! #1

Thanks for your work. I'm not sure if this can help, since it's more about the uart communication rather than the Bluetooth one, but I founded some resources some time ago, and they might be handy.

Thanks for sharing that!

From a quick look at https://gitlab.com/nbrgmn/wall-e-esp8266-automower/-/blob/develop/Robomower_V0.8.pdf?ref_type=heads it does look like it might be helpful in decoding the requests/responses. Which is the main thing left to do here to support more features/commands

I'm glad it can be useful.
Just one question: would you think that your work can work with esphome Bluetooth proxies? I think that would be a key element in order to be able to reach the mower across the whole garden

That's the plan!

I've started to put together a HA component for the mower. I'm now waiting on a longer Ethernet cable to arrive so I can setup a ESPHome Bluetooth proxy near the mower

Thank you!! While waiting for the PR to be accepted, do you think I can try it out? How can I import it?

alistair23 · 2024-01-21T10:42:39Z

You can test it.

If you apply this diff (custom components require a version)

diff --git a/homeassistant/components/husqvarna_automower_ble/manifest.json b/homeassistant/components/husqvarna_automower_ble/manifest.json
index cb3ee2a502..bd7db5f1f1 100644

Then just rsync the entire homeassistant/components/husqvarna_automower_ble directory from the PR to /root/homeassistant/custom_components/ on your HA instance

You will also want to enable debug logging by adding this to your homeassistant/configuration.yaml file

logger:
  # default: debug
  logs:
    custom_components.husqvarna_automower_ble: debug
    custom_components.husqvarna_automower_ble.config_flow: debug
    automower_ble.mower: debug

Then just reboot. Let me know how it goes, I have only tested it on a 305

AlessandroTischer · 2024-01-21T11:19:35Z

Then just reboot. Let me know how it goes, I have only tested it on a 305

Ok, i installed the integration and I can get up to the configuration wizard. There I can see a blank textbox with no hints. I tried inserting the Bluetooth address but it gives me an unknown error.

In the log I get this:

You need to insert the Bluetooth address in the box. I think I still need to provide strings which is why it's empty.

Did you enable logging in the config? There should be more details then that

AlessandroTischer · 2024-01-21T21:16:55Z

Yes, I imagined that could have been the problem, but it's a minor thing.

Yes, I enabled it. I tried it again and found that missed an error:

Now I'm wandering: is the Bluetooth proxy via esphome supposed to work already? I took it for granted and tried it with the mower near an esp I already have in the garden (the server is in the basement...).

Then the device page in HA has a "ESP start Scan" button. I usually click that to force a connection to the mower first, before loading the integration.

It's the same thing I have to do for the official HA Gardena integration as well. I see the device connect in the ESPHome logs. You can check there to see if a connection is being made.

Obviously make sure the mower is in range :)

You need to get a connection here. You should get something in the log saying it connected. I suspect the issue is that the mower isn't in pairing mode. I have updated the documentation here: home-assistant/home-assistant.io#30921

Basically make sure the mower is in pairing mode before doing this. For the 305 I need to power cycle the mower and trigger a connection in the first 3 minutes after startup.

Also, try moving the node closer. The timeout while connecting is weird and coming directly from the HA Bluetooth stack. You should be able to connect to the mower even without my integration.

Thanks for testing! You have helped me update the documentation already :)

Basically make sure the mower is in pairing mode before doing this. For the 305 I need to power cycle the mower and trigger a connection in the first 3 minutes after startup.

I'm not sure how the 305 connects, but my 315 has a connection menu where I can start the pairing, but I found that your 3 mins method seems to work better for this: when the mower has been turned on for a long time, even if I go to the pairing menu, the esphome node can't find the mower. Instead, during the mower startup, it is discoverable (I see the same behaviour using nRF connect app on my android phone). With the husqvarna app, instead, the mower can be connected only when in pairing mode (from its menu), and I can connect to it using the 4 digits pin.

Do you have any idea?

I hope this information will be somewhat useful for the project

bleak.exc.BleakError: Error ESP_GATT_CONN_TIMEOUT while connecting: Connection failed due to timeout

This is coming from the ESP device. I don't think there is much I can do here. How far away are the two devices? You can try moving them closer together to see if that works.

This one is a good error!

That Insufficient authentication in the Characteristic means that the two devices are not paired. They are connected (so within range) but not paired.

I'm not sure how the 305 connects, but my 315 has a connection menu where I can start the pairing, but I found that your 3 mins method seems to work better for this

The 305 has the same setting. For me that menu option does nothing. The official app can not pair with the mower using that menu option. The only thing that works for me is the full reboot and then connect in the first 3 minutes. Even the official app with an Android phone held next to the mower took a few tries. So it might take a few goes.

Try pulling the latest changes. I have been working to try and improve the connection reliability as I test more with my mower.

Then just keep rebooting the mower and reload the integration until the husqvarna_automower_ble logs prints the Characteristics without any Insufficient authentication errors. Then the mower is paired. You only need to pair it once per BLE proxy, so don't stress about it being a bit of a pain

The only thing that works for me is the full reboot and then connect in the first 3 minutes. Even the official app with an Android phone held next to the mower took a few tries. So it might take a few goes.

Try pulling the latest changes. I have been working to try and improve the connection reliability as I test more with my mower.

I tried, since I saw some commits, but I'm not sure how to do so. I downloaded the folder from your homeassistant/core fork, but I'm not sure it's the latest (commit name is still initial commit)

Then just keep rebooting the mower and reload the integration until the husqvarna_automower_ble logs prints the Characteristics without any Insufficient authentication errors. Then the mower is paired. You only need to pair it once per BLE proxy, so don't stress about it being a bit of a pain

I will try, but I did so already a few times without success...

AlessandroTischer · 2024-02-02T16:01:01Z

I downloaded latest commit. Now I can finally finish the config flow and the integration entity is created...
But it instantly shows "failed to setup". I already tried the setup at least 10 times.

I see that now, as soon as the esp node connects to the mower, the bt logo appears on the mower display and doesn't disappear.

Now the home assistant log reports:

This error originated from a custom integration.

I also tried to move the security level on the mower from medium to low, but it doesn't help.
Now I'm wondering: is it correct that I never have to insert my mower pin while configuring the integration?
I don't see any way to remove it from the mower, and I'm not sure how the connection can be handled without it.

This means it is connected but not paired. You need to make sure the mower is in pair mode then reload the integration.

I think you are missing some logs. You can SSH to the HA instance and run this? It will provide more logs and in an easier format

cat ./config/home-assistant.log | grep mow

Good question. I have decoded sending the PIN, the Python library supports providing it. But I have never needed to actually use it. You might need to the PIN to change some advanced settings (which we don't support). Currently everything works for me without using the PIN. My mower is set to low security.

If we find out we need the PIN I can look at adding support for that

alistair23 · 2024-02-04T22:29:52Z

Great! That is really helpful.

The mower is connected and paired. The Insufficient authentication error is from earlier.

You can communicate with the mower as well, so it's mostly working. The issue is the mower model lookup in the Python code. It's using the wrong values. It worked for the 305 by coincidence. I have pushed a fix, if you update to the latest from my PR it should work for you

AlessandroTischer · 2024-02-04T23:48:35Z

Great! That is really helpful.

I'm happy to help as much as I can!

I have pushed a fix, if you update to the latest from my PR it should work for you

I can finally confirm the integration setup works! Tomorrow I'll try to test it (it's 1am here, but I still wanted to try to connect).
For now, I can only say a massive thank you!

BTW, Just out of curiosity: do you think that it would be feasible to add some kind of ble beacon functionality to track the mower position in the garden in the future?

alistair23 · 2024-02-05T10:09:32Z

Awesome! I'm glad it's working. This has helped narrow down a few bugs, so hopefully it helps this get merged

I don't think it would be feasible to track the mower position via BLE. Looking at some existing features in HA like iBeacon we could probably detect a rough distance. But that isn't super useful.

It would probably be easier to attach a GNSS device to the mower and use that instead

AlessandroTischer · 2024-02-05T11:25:38Z

Awesome! I'm glad it's working. This has helped narrow down a few bugs, so hopefully it helps this get merged

About this: why don't you create a custom component with HACS requirements in the meanwhile? It's quite straightforward and it would help for having more testers I think.

You're right

It would probably be easier to attach a GNSS device to the mower and use that instead

It would be nice to find some way to keep an esp and/or the gnss powered/charged on board of the mower itself, I need to look inside and see if I find some 3v or 5v pins

alistair23 · 2024-02-06T00:12:59Z

I really don't want to be maintaining an out of tree component. I have a few currently installed and I'm trying to get rid of them.

I would like to get this upstream so that it can benefit the most number of users and be included in the HA infrastructure. I must admit I didn't realise that it would take so long just to get a response though.

There are power pins somewhere :P The question is how easy are they to get to and then can you setup something in a secure and waterproof way.

A little solar/battery node might be easier. Although I now have the mower house setup, so that probably won't work too well for me

alistair23 · 2024-02-12T09:35:01Z

Have you had a chance to test this a bit more?

AlessandroTischer · 2024-02-12T17:42:03Z

Have you had a chance to test this a bit more?

Unfortunately not, I'm having some issues with the loop wire that is broken in multiple points (I hope the station is ok... Last spring I had to replace the board on the station since it fried during the winter). Now I have very little time, but I'll try to repair it ASAP. Then, I'll test it as much as I can.

alistair23 · 2024-02-13T09:29:24Z

Aw no! I'm sorry to hear that

No rush, I was just checking in

AlessandroTischer · 2024-02-20T21:24:46Z

Aw no! I'm sorry to hear that

Unfortunately the board was actually fried.
I just replaced it.

After the setup with the new loop signal, the mower loses all its connections, and now I can't get it to connect to HA again... Tomorrow I could send you the logs again, if it's something useful. I also updated the integration to your latest commit.

alistair23 · 2024-02-20T23:09:54Z

Urgh! That's a pain. If you send the logs I can investigate. Sometimes it does take a few tries to get a connection though

AlessandroTischer · 2024-02-25T12:15:39Z

husqvarna_logs.txt

I managed to connect to the mower.
Battery level seems ok and changes correctly when it's mowing or charging.
Mower status is instead locked on "docked", even if the mower is in the middle of the garden. It also does not respond to any command from the integration.
Moreover, if the server or the esp bt_proxy node reboot for any reason, it seems to disconnect and never connect to the mower again unless I pair it manually again.

alistair23 · 2024-02-26T12:13:34Z

Great!

Looking at your log I never see the mower send a "Mowing" activity. So the mower might not be connected when that happens.

The connection is pretty unreliable. That seems to be an issue with Home Assistant. I have the same issue with other BLE devices. I'm not sure there is much I can do in the integration to improve that unfortunately. I have tried testing a few different approaches, and they don't seem to help too a lot.

I can see you starting the mower in the logs. It looks like it works, but there is a strange exception in the Python code. I'll add more debug logs, so if it happens again hopefully we can see what's going on.

Hi! Sorry for the late reply, but I really didn't have any chance to look at the mower integration. Did you have the time to update the project to get more debug instead?

alistair23 · 2024-03-13T11:54:22Z

No worries. I have been slowly tweaking and updating things. The BLE connection is now as reliable as my other BLE connections. I'm still trying to improve it though

AlessandroTischer · 2024-03-13T12:41:28Z

No worries. I have been slowly tweaking and updating things.

I pulled latest commit, but I still have problems connecting to the mower. I attach latest logs.

Do you mind opening the log, finding the line

File "/usr/local/lib/python3.12/site-packages/automower_ble/mower.py", line 259, in probe_gatts

and including the lines around it. Something is failing in the decode and I can't see what

alistair23 · 2024-03-13T22:11:51Z

Ah, I see in the log it is Insufficient encryption. So you aren't paired

AlessandroTischer · 2024-03-13T23:17:14Z

Ah, I see in the log it is Insufficient encryption.

Do you still need the logs you asked before?

So you aren't paired

Is there anything I can do about it?

alistair23 · 2024-03-14T00:01:44Z

You need to put the mower into pair mode and then try again

GitWally · 2024-03-21T06:12:16Z

Then just rsync the entire homeassistant/components/husqvarna_automower_ble directory from the PR to /root/homeassistant/custom_components/ on your HA instance

Then just reboot. Let me know how it goes, I have only tested it on a 305

Hello
I have a 305 and would like to test your integration with my HA Supervised (which has a BT antenna connected), if you think this could be helpful, while waiting for the merge to be approved.

I understood I have to download files to my HA instance.
After reboot I think a configuration should be made: BT address, user, password ... am I right?
Will there be a UI or should I write something in configuration.yaml? Or should I execute commands from terminal?
Thanks

Hello,
may be I am new at this type of installation, but when I try to add https://github.com/alistair23/AutoMower-BLE as Custom component I get the following error: "<Integration alistair23/AutoMower-BLE> Repository structure for main is not compliant"

So I did:

git clone to /usr/share/hassio/homeassistant/custom_components/AutoMower-BLE
set logger options in configuration.yaml
restart

But still can't see the new integration: searching for BLE ble or automower gave no result (except the official Husquarna Automower)

I came to the conclusion I should take files from another folder: may be the following one?

https://github.com/alistair23/homeassistant-core/tree/alistair/husqvarna_automower_ble/homeassistant/components/husqvarna_automower_ble?

I copied all 6 files from homeassistant/components/husqvarna_automower_ble

and rebooted (the whole system, not just HA)

Anyhow still no new integration dealing with "hus" or "automow" or "ble" found.
What am I missing?

Thanks

For the sake of completeness, I have downloaded and moved files as "root"

And this is the content of my homeassistant/custom_components/husqvarna_automower_ble folder

The thing is, I cannot find the new integration:

You said:

Ok, i installed the integration and I can get up to the configuration wizard. There I can see a blank textbox with no hints. I tried inserting the Bluetooth address but it gives me an unknown error.

No, sorry, this is the first time I try to add a not-yet-release integration and I didn't know.
This is manifest.json I have:

documentation says:

The version of the integration is required for custom integrations. The version needs to be a valid version recognized by AwesomeVersion like CalVer or SemVer.

So, as you suggested here i added

"version": "0.1.0"

so these are last lines of manifest.json now:

Hello,
I put the 305 in pairing mode and tried to pair 3 (or more) times.
I'm using the MAC address found in known_devices.yaml identified as "305" by the name.
But I came across the following unknown error:

in home-assistant.log I found:

GitWally · 2024-03-23T16:58:18Z

Hi guys,
looking at the logs, to see if there is something I could do, I noticed the last line of home-assistant.log is referring to python3.12

  File "/config/custom_components/husqvarna_automower_ble/config_flow.py", line 105, in async_step_user
  File "/config/custom_components/husqvarna_automower_ble/config_flow.py", line 69, in async_step_confirm
  File "/usr/local/lib/python3.12/site-packages/automower_ble/mower.py", line 217, in probe_gatts

The fact is I don't have such a dir, because I have just python 3.9 (default version for Debian 11):

I assumed an upgrade to Python 3.12 is required, so I installed Py 3.12 alongside 3.9.
Now the home-assistant.log says something different ...

Last 3 lines are the attempts I've done after Py upgrade.

Since in previous messages there was this reference

File "/usr/local/lib/python3.12/site-packages/automower_ble/mower.py", line 259, in probe_gatts

I tried to see the content of such a dir: there is not a "automower_ble" folder yet.

What should I try now?

Thanks

Hello @alistair23
I'm afraid those lines are gone: they were generated in the morning (saturday 2024-03-23 between 08:48 and 08:50), when I was still running on PY3.9.

Then I have installed PY3.12 and log has changed.
Since the log was referring to a different PY version, I assumed it was required.
Now my first row in home-assistant.log dates as 2024-03-24 17:05 and the only reference to "mow" are these:

Anyhow I have

restarted HA
set 305 in pairing mode
tried to pair using HA App on iPad > see logs between 09:41 and 09:44
tried to pair using HA App on Android > see logs around 10:00
tried to pair using Chrome from PC > see logs after 10:02

In my opinion they seem to be different.

This is the full 2024-03-25_home-assistant.log.txt from the re-start.

Many thanks

The full log provides a lot more information

Unable to install package PyBluez==0.22
...

      error: command 'gcc' failed: No such file or directory
      [end of output]

Which seems strange, that might be worth fixing.

Your HA instance does see the mower, as I see these lines

2024-03-25 09:41:35.361 DEBUG (MainThread) [custom_components.husqvarna_automower_ble.config_flow] Discovered device: <habluetooth.models.BluetoothServiceInfoBleak object at 0x7fc27fc95fc0>
2024-03-25 09:41:35.362 DEBUG (MainThread) [custom_components.husqvarna_automower_ble.config_flow] D8:B6:73:C2:BC:05 manufacturer data: {1062: b'\x05\x04$TO\r'}

But the connection fails with

bleak.exc.BleakDBusError: [org.bluez.Error.Failed] Disconnected early

Then you just get these messages

No backend with an available connection slot that can reach address D8:B6:73:C2:BC:05 was found

You might want to force a scan or discovery from the Bluetooth adapter before reloading the integration.

This issue is getting a bit out of hand.

I'm going to close this issue. If you are still having problems just open an separate issue. That way things are a little easier to track and manage

GitWally · 2024-03-25T12:48:25Z

I do agree: i will fix PyBluez first of all.
Thanks again
