[bulldog5046]

Thanks for the report.

Can you bring the machine and HA Bluetooth dongle closer together? It seems the base bluetooth connection is failing rather than the Nespresso integration.

If you're familiar with the HA CLI you can test the bluetooth connection with:

bluetoothctl connect EC:E4:50:13:F7:1F

Might need to be ran from the homeassistant docker instance depending on your environment

[saya6k]

It's hard to move HA server. Can I use ESP32 Bluetooth Proxy?

I got this from ESPHome Bluetooth Proxy. (ESP32-S3-Box-3)

I've not ben able to get the bluetooth proxies to work to test with. But this is interesting:

2023-11-19 00:38:31.475 ERROR (MainThread) [custom_components.nespresso.nespresso] Failed to onboard Expert_ECE45013F71F

Try doing a factory reset again on the machine, this usually happens when an onboarding process has previously failed and leaves the machine with a new auth_key installed but failed to complete the process and save the device & key into HA.

Alternatively, move the coffee machine closer to the HA server for the pairing process. Part of it involves lowering the txPowerLevel so range will matter for it to successfully install the new key and complete pairing.

[saya6k]

After I reset once again, I succeed to connect and brew cofffee with it. Great.

I wish I have device to bind all entities. It would be better to get status.

And there are some entities that seems binary sensor is more suitable type.

Overall, nice work. Thanks.

I agree. The entities were brought forward from previous project and they don't seem correct or useful. However, the brew features are probably what most people want.

Glad it's working. Hopefully more dev to come :)

Can I control capsule count in this integration? Now I gain ability to brew coffee in Home Assistant, but lose ability to count capsule in official app :(

And it would be better to use HACS format so that I can register github to HACS.

I don't believe it works, it came from the old codebase. I don't have anything that can pair to my machine to see the original app functionality. Could you raise a feature request and i'll take a look at it when i can. Please give as much info as possible.

I will move this across to HACS in time but you are the first beta tester as far as i know so i need some feedback :)

[saya6k]

OK, it's 2 AM in South Korea, so I'll test this while I brew coffee tomorrow.

[tikismoke]

Binary sensor was done in mqtt because i was more using the python script than the integration. Those because I got no correct knowledge and no help only criticism 'it do not work'...

For caps count it is done automatically by the machine. Brew a coffee count less one. You only have to make inventory once a buy and change the value read here: nb_capsule = device.char_read("06aa3a15-f22a-11e3-9daa-0002a5d5c51b").

@saya6k does it mean you where able to use the esp as bridge between ha server and the coffee machine? Because effectively distance was the higher issue off nearly all users.

[bulldog5046]

Ok cool. Thanks for the info. Mine has always reported 65535, probably because i've never had an app conencted to initialize it.

Just did some testing and that characteristic is also writable:

Connected: True Paired: True Onboarded: True { 'Fault': 1, 'always_1': 1, 'awake': 0, 'caps_number': 15, 'capsule_engaged': 0, 'capsule_mechanism_jammed': 0, 'descaling_counter': 65535, 'descaling_needed': 0, 'sleeping': 1, 'slider': 'closed', 'tray_open_tray_sensor_full': 0, 'tray_sensor_during_brewing': 0, 'water_engadged': 0, 'water_hardness': 4, 'water_is_empty': 0, 'water_temp_low': 1}

Will look to add this feature so yuo can manage caps in HA 👍

[bulldog5046]

Functionality added and brought into HA as service nespresso:caps to manage the caps counter.

And It took 3 minutes to poll capsule counter after update counter to 100. But succeeded to update capsule counter.

Yes, I did add a note on the example i've given about this. I'll have a think about how we can update this part faster rather than wait for the next polling.

[tikismoke]

I'm surprised by this value too: descaling_counter 65535

I thing you must define a water hardness. (It's also a read/write)

Like the caps count it seems that this one do not change as you never use the official apps.

[bulldog5046]

@tikismoke Any chance you've seen a case where a factory reset doesn't clear the auth_key? I'm not sure if i've managed to brick my machine.

Factory reset isn't clearning the key and the last known key does enable access to the characteristics but they are all blank.

[tikismoke]

@bulldog5046 no indeed.

I assume you lay have put the com part in an indésirables status.

Cut power for a night and retry the next day.
