BSB-Lan integration

Hi,

Sorry for the late reply.

You should share how you wrote things into your configuration.yaml.

I cannot really advise without seeing the code which produced the error.

Hi Gabor, many thanks for your help - it finally worked ! I’ll have to learn programming automations but this is definetly an important step

This working for me.

I’m missing “mqqt:” at the beginning on purpose, because I’m calling yaml from configuration.yaml like this:

Perfect, the Drinking Water Push is working that way.

My next aim is getting the Presence button “Temporary Comfort”
10110 Benutzerdefiniert - Heizbetrieb Heizkreis 1 (Temporär)
with Options

Reduced
Comfort
“- - -”
controlled via Homa Assistant Dashboard.
It must be similar or close to your

Do you or anybody has an example as well?

Hello

I wanted to ask if it is possible to make the same adjustment for the second circuit as for the first circuit.

Thank you
Regards
Mariusz

GSzabados · October 10, 2023, 8:41am

Is this set up through the official integration or through MQTT?

If MQTT, then you need to use 1010, instead of the 710 like as it is visible in the previous post’s example.

If the official integration, then @liudger might be able to give you an answer.

MariuszC · October 10, 2023, 8:59am

Now I have it done via MQTT but I would like to do it on official integration

liudger · October 11, 2023, 11:50am

Hi Mariusz,

It just that currently I don’t have much time. And I want to check if another project that will control BSBLan device with mqtt could be better. They are working to make bsblan work out of the box with mqttt and the sensors and climate/ hot water will be automatically detected. Than there is no need for this integration. But that project also goes really slow

remai · October 29, 2023, 7:23pm

This is the configuration.yaml I use to integrate home assistant with my recently acquired BSB-LAN over MQTT. While I am sure there are possible improvement, I am quite happy with its current state. I post it here hoping it might help someone. Some related notes to take into account:

All entities are tied together to one MQTT device.
I calculate an average house temperature from multiple sensors and the heat pump is configured to adjust heating curve based on it with 50% weight.
The heat pump electricity usage might not be accurate. I use a utility meter helper to track daily usage and integrate it into the energy dashboard.
The climate and water heater entities work with automations and can be displayed nicely with HA cards.
The climate entity uses “cool” for “reduced heating setpoint” which is illogical, but I couldn’t find a better way.
All the required line numbers should be exposed in BSB-LAN settings.

Have you had any success integrating immergas boiler to HA? I got Immergas EOLO MİNİ I want to be remote controlled, couldn’t even find protocol its communicating with it’s OEM remote.

I have since modified the climate entity to remove the “cool” mode as it doesn’t make sense if there is no cooling circuit. Instead presets are used to indicate the heating mode.

The only remaining issues I have are due to home assistant’s thermostat card colors: orange is used for the lower temperature target, and blue for the higher temperature target.

Hello all;
Happy to see this post since I just installed an ESP32/BSB-LAN box sending my boiler (Chappee Klista HTE, LMS14 regulator) parameters to MQTT broker and from then being integrated into HA.

My heating system has 2 zones:
zone 1: 1st floor with traditional radiators. Direct circuit.
zone 2: groundfloor with under-floor heating an a 3-way valve. An official and mandatory Chappee probe is associated with this second zone.
I would like to mimic a second (optional) Chappee probe for a better regulation of the 1st zone using my Home Assistant temperature sensor.
Is this feasible ? When I dig into the BSB-LAN webserver parameters the only “setable” parameter associated with zone 1 is the Room temp1 model (variable #8742):

BSB-LAN output (in French, sorry…):

In the LMS14 documentation I find the following definitions:

When there is no room sensor I understand that the room temperature is derived from a “room model” but I do not understand how that works and how sending a value to set 8742 could mimick my Chappee sensor…
Here is the relevant part of the doc about room model:

Any help will be appreciated !
Cheers,
Jacques

babajun · February 15, 2024, 10:00am

At my room sensor unit I was able to configure which zone will be controlled. Here it’s possible to activate the sensor for both zones.

jnilo · February 16, 2024, 6:06pm

There is a very simple way to mimic the sensor of your boiler using any temperature sensor you have in your home (Thank you Frederik, sponsor of the great BSB-LAN project !) . Here is the automation I created to make my boiler think that my 10$ Sonoff sensor coud do as well as the official 200$ Chappee sensor

- alias: "Publish Sensor Value to MQTT as BSB-LAN topic"
  trigger:
    platform: time_pattern
    minutes: "/5"  # Trigger every 5 minutes
  action:
    - service: mqtt.publish
      data:
        topic: "BSB-LAN"
        payload: "I10000={{ states('sensor.your_sensor_entity_id') }}"

Replace sensor.your_sensor_entity_id by the sensor entity of your choice.
The same trick can be used to feed a temperature for zone 2 (I10001=) or zone 3 (I10002=) or to feed an external temperature (I10003=) or to simulate a presence. Check 6.3 and following sections of the excellent BSB-LAN documentation !
Jacques

NB: those parameters are valid for LMS14 Siemens based regulators. They may differ for other regulators. Check the doc !

GSzabados · February 18, 2024, 8:50pm

And does the heater take those values into account? Is that your experience? Isn’t a setting should be changed to use the room sensor than the room model?

jnilo · February 19, 2024, 9:38pm

It does the job perfectly and this approach is well documented in the BSB-LAN manual (section 6.3 s.q.q.). Much simpler that trying to play around with the Room model And I received very helpful suggestions from Frederik (BSB-LAN lead developer) on this alternative approach.

Thanks for the pointer. To be honest, I completely missed this, which is exactly why I was asking the original question. That is the setting which has to be changed to activate the “room influence”.

Therefore you have to activate the function ‘room influence’ (e.g. parameter 750 for circuit 1, parameter 1050 for circuit 2) before.
