Please check your config.

Just noticed this,

nefiteasy:
  devices:
    - serial: !secret buderus_serial
      accesskey: !secret buderus_accesskey
      password: !secret buderus_password
      name: Combi
      sensors:
        - year_total
        - status
        - supply_temperature
        - outdoor_temperature
        # - system_pressure
        - active_program
        - hot_water_operation
      switches:
        - hot_water
        - holiday_mode
        #- fireplace_mode
        #- today_as_sunday
        #- tomorrow_as_sunday
        - preheating
        - home_entrance_detection
        - weather_dependent
        - lockui

According to the above config, 1 sensor and 3 switches are disabled but the addon ignores the configuration and exposes all of them.

Additionally, the "name" component doesn't seem to make a difference.

Can anybody else test this?

The new release 2021.3.0 of HA requires to have a version in the manifest.json file.

Hi Ksya,

First of all, thanks for all the work you've put in the component!

I used your component without problems on a Nefit Easy Control, but I switched to the Bosch Easy Control recently. Can you please confirm if your component should work with this thermostat?

I'm having issues setting it up.
Here's a link to the forum post i've made:
https://community.home-assistant.io/t/nefit-easy-client/8148/187?u=mkoninkx

Thanks in advance!

Let me start with saying thanks everyone for the effort in this custom component for homeassistant.
I'm having isseus with enabling the Today as sunday and Tommorrow as sunday switches, when i enable the switch it
immediately goes back to off and it doesnt change the setting when i look in nefit app.
i have the same problem with Fireplace and Holiday.
anyone else having this isseu?

Hi,

Running HASSIO 2021.2.3 on RPI3b+.
Using Nefit Easy already for long time and always update to the latest version.
I'm not using HACS, but always update by copying the code to custom_components/nefiteasy/ folder.

According to the "read.me" Configuration section, it should be possible to add the config via Integrations now.
However Nefit doesn't showup in the list when trying to add it.
Am I missing something ?

Also in the "read.me" Installation section, it's not "explained below" how to add NefitEasy to your configuration.yaml.

I switched to this version of the nefit easy integration, but the year_total property seems unavailable. Is there anything special I could/should do to get it available, or should it actually be available? Many thanks.

Can you please make this component HACS compatible? (See https://hacs.xyz/)

Hello,
Is it possible to add support for these devices?

The connection magic key issue with xmpp is solved by robertklep here robertklep/bosch-xmpp#4.

Hi all, first of all big thanks for this great software!

I installed HomeAssistant a few days ago, and included the Nefit Easy integration. I included two installations, one is without problems but the other has a very concerning problem.

Situation without Nefit Easy integration connected to my account:
Nefit Easy follows program as expected; programmed 19.5C, when temperature comes down to 19.6 or 19.5 the Ecomline HRC30 starts heating.

Situation with Nefit Easy integration connected to my account:
Nefit Easy device AND Home Assistant give 19.8C actual room temperature, programmed is 19.5C, and every 5 minutes the Ecomline starts heating, after 5 minutes back into standby, and so on.

I know this sounds very unlikely, but I have experienced this twice (once reinstalled the newest version), and the behaviour is pretty consistent.

I tried to narrow down the issue, but as I new HA user I notice there seem to be multiple copies of the configuration data. If I remove the Nefit Integration, and restart, hass still complains about not being able to fullfil nefiteasy configuration. Even if I comment out all nefiteasy stuff in confguration.yaml, it still keeps complaining. Even when I throw away the .db file it keeps complaining, but after a few restarts this error message disappears.

How can I reliably change my config items, making sure those are actually the items being used by hass? Perhaps if I reduce the number of entities (sensors and/or switches) behaviour changes....

Hope I can help with this, and if you have an older Nefit heater, please monitor your nefit.status entity (history graph is ideal for this) to make sure your heater is not switching on/off every 5 minutes. This is killing your heater!

Problem
Even with the changes in place in /etc/ssl/openssl.cnf, Hassio is not able to connect to the Bosch cloud. I keep getting the double notification error on my Raspberry Pi:

Unexpected disconnect of [xxx] with Bosch server. Try to reconnect..
Did not succeed in connecting [xxx] to Bosch cloud after retrying 3 times. Retry in 30 seconds.

This was working for quite some time now, but now all of a sudden the problems are back.

I'm on HA 0.116.4.

Is it possible to get this resolved:

Using slower stringprep, consider compiling the faster cython/libidn one.

I have succesfully managed to install the Nefit Easy integration using the documentation from README.
The integration is showing up in both HACS and Default integrations.
I have entered the correct details upon installing, however I cannot find a single entity when I'm trying to add it to my overview.

Any way to troubleshoot this? It's running on

Thanks for a great plugin. I wonder if it would be able to activate the shower timer via the plugin?

The shower timer function in the nefit app resets, so you have to set it every time prior to a shower. Would be great to have a script in HA that activates it say every 10 minutes via this script if feasible.

I have no clue if this can be done, thought I’d ask.

Hello, I hope you can help me. I've update HA to the latest version (Hassio via Docker) version 0.101.2, All entities are available but I cannot set temperature.service climate/set_temperature error. Did I miss something. Thanks for helping out.

When using latest HA version (2020.12.0) i cannot add the Nefit repo to the HACS add-on store. The supervisor (2020.12.6) tells me:

20-12-14 19:16:02 ERROR (MainThread) [supervisor.store] https://github.com/ksya/ha-nefiteasy is not a valid add-on repository

A failure as a heads-up for next version of HA-core: 2021.6 will kill Nefit Easy addon :( unless the version key is provided.
A small fix I reckon :)

Can you add? I love this addon; great work!

For changing min and max temperature (and maybe more), without removing and adding the integration again.

@ksya Do you know how the "Hot Water" switch is working and how I can verify that with the Nefit app? I can see it writes to an endpoint based on "clock" or "manual" mode, state of the switch is however fetched from uiStatus. I can't seem to change the value in uiStatus.

It's not working for me either when I rollback to an older version, so I wonder if that was ever functional.

It was functional I remember now, but I think something broke it later.

When the integration is running and I open the phone app, the following errors occur in the HA log

Any idea where this is coming from? It looks like the integration is working however

Hi,

it looks like there is an endpoint that offers calibration of the temperature

https://github.com/marcelrv/nefit_easy_protocol/blob/master/hc1-temperatureAdjustment.md

how do you think about adding this into this integration?
i think it could be very useful for automations, especially when you have multiple temperature sensors in HA

Custom integrations without version key in their manifest file will be blocked from loading starting with Home Assistant 2021.6.

This is announced in the Breaking Changes for Home Assistant Core 2021.4:

Custom integrations: Version warning

Custom integrations now require a version key in their manifest file, this also means that all custom integrations now require a manifest file.

If you are using a legacy custom integration like custom_components/awesome.py this now needs to move to custom_components/awesome/__init__.py so you can add custom_components/awesome/manifest.json to it.

For more information about integration, manifests have a look here: https://developers.home-assistant.io/docs/creating_integration_manifest

For now, this will create a warning on startup. But this will be blocked from loading if it’s missing a version in the manifest starting with Home Assistant 2021.6.

Hi, thanks for your work on this integration.

I have successfully installed the integration, I see the climate control on the overview. I can also set the temperature.
I am unable to create an automation with an action which sets the temperature to a certain value.

Hopefully someone can explain how I can achieve this.

Thanks.

Hi ksya,
thank you for the Nefit integration.
I am trying to get it working.
During startup I find the error messages below in the Home Assistant log.
I don't think it is a SSL issue.
Can someone take a look?

from the manual:

Add "https://github.com/ksya/ha-nefiteasy" to your custom repositories in the Settings tab of HACS.

adding makes HomeAssistant (latest version) say it's "Invalid Add-on repository!"

Thanks for this integration.

Can we have year total consumption be exported as kWh ?
I need this value to calculate monthly costs. Maybe exposed as a different name.

Currently Nefit sensor have the following value for the consumption
sensor.nefit_year_total

However, this is a yearly total. Is there a way to add a sensor for the monthly consumption for tracking the bills?

Unfortunately it does not work anymore after the latest update using Home Assistant 2021.1.1
Overview window is showing Nefit dialog with the text unavailable. A total reinstall did not solve the issue.

To prevent my children from playing with the thermostat and turning the heat on, I would love to see the "Thermostat Lock" swithc be implemented.

Thanks in advance, Harry

am i doing something wrong? :/

I tried to install ha-nefiteasy as an add-on repository. Unfortunately, nothing happened except that this showed up in the log file:

21-04-09 20:13:58 INFO (MainThread) [supervisor.store.git] Cloning add-on https://github.com/ksya/ha-nefiteasy repository 21-04-09 20:13:59 ERROR (MainThread) [supervisor.store] https://github.com/ksya/ha-nefiteasy is not a valid add-on repository 21-04-09 20:13:59 INFO (MainThread) [supervisor.resolution.module] Create new issue IssueType.CORRUPT_REPOSITORY - ContextType.STORE / 68595fea 21-04-09 20:13:59 INFO (MainThread) [supervisor.resolution.module] Create new suggestion SuggestionType.EXECUTE_REMOVE - ContextType.STORE / 68595fea 21-04-09 20:13:59 WARNING (MainThread) [supervisor.store.data] No repository information exists at /data/addons/git/68595fea 21-04-09 20:13:59 INFO (MainThread) [supervisor.store] Loading add-ons from store: 68 all - 0 new - 0 remove 21-04-09 20:13:59 INFO (MainThread) [supervisor.resolution.fixups.store_execute_remove] Remove invalid Store: 68595fea 21-04-09 20:13:59 INFO (MainThread) [supervisor.store.git] Removing custom add-on repository https://github.com/ksya/ha-nefiteasy

Did I press the wrong button? Would appreciate any help!

First of all thank you for this awsome functionality! I installed it a few days ago and for me it work flawless! I use al the sensors there are available but I only miss one and thats the return tempature. Is it possible to ad this one?

I live in the Netherlands and winter is coming. Knowning the return tempature is a big plus because with that information I can manualy adjust the supply tempature for the best efficiency of the CV. The bigger the difference between the supply en return tempature the higher the efficiency.

This would greatly enlarge the functionality. Using a general service "call endpoint", with given parameters, anything can be done from within Home Assistant, even though it is not directly implemented in this integration.

Request to set the active program through a switch.
I have 2 programs, would be nice to be able to change them within home assistant

I changed my post with a shorter summarization...
After recent update(s), probably after Home Assistant 0.116 or HassOS 4.13 or 4.14, I got serious problems to get Nefit Easy connected.

Problem:
After HA restart / reboot or powercycling Raspberry Pi3, I get "Unknown error" in the logging (Nefit component does not connect). This is the only logging I get, even with debugging on (as descibed on the Nefit Easy install page):

2020-10-31 19:47:46 DEBUG (MainThread) [custom_components.nefiteasy] Unknown error
2020-10-31 19:47:46 DEBUG (MainThread) [custom_components.nefiteasy] Waiting for connected event

I did some debugging but I still have no clue. Only thing I know is that Nefit tries to connect in an endless loop.
Sometimes it connects after very long time:

In the "init.py" function, routine "await asyncio.wait_for(self.nefit.xmppclient.connected_event.wait(), timeout=29.0)" raises exception after timeout, which results in the "Unknown error". So xmppclient does not connect.

Workaround:
Disconnect network cable from my RPI3 for a few seconds.
After reconnecting the network cable, Nefit connects almost immediately (strange).

Any ideas ?
