Oh my God!!! @john30 you are the KING! I've waiting for this feature from the beginning of using ebusd!!! Edit: updated to new version and it works!!! Thank you!!! |

what do you want to modify exactly? since this is highly dynamic, you'd have to adjust the settings in /etc/ebusd/mqtt-hassio.cfg to achieve the desired changes |

@andrejs2 sorry for off topic, but would you mind sharing your HA configs? Seems that ive been trying to create a similar thing as you and it does partially work, but had some problems which i cannot fix (like with input selects for modes). Surely the whole community would greatly benefit from each others configs. |

Thanks. That's very interesting because you took a very similar approach to input_selects as myself, but while my input_numbers work perfectly fine, input_selects often glitch (for example changing the mode in HA doesnt change the mode on the boiler controls or other way around - changing mode on boiler controls quickly resets it back to the value set in HA). Will need to look into that again. A couple of questions:

Thanks @john30 for the feedback and all the work you put into this project, I think this upgrade is really opening another new level. There are number od options to change (switch (on-off), select,...I use them to select desired room temp, heating curve, backup mode, storage load, heating circuit mode (auto, off, on...).
input_select: input_number: input_datetime: Anyway I'll dig into the config file. Thanks! |

ah, you mean writable values. yes, those are supported as well and if you change the mqtt-hassio.cfg line 114 to "filter-direction = r|u|^w", then write messages are included - by default they are not, as this really opens up a lot stuff that can be done wrong by a simple click on HA UI. You don't need to change the file itself, instead you can also pass another ebusd start parameter overriding the line like this: |

Thanks @john30, MQTT autodiscovery works really well out the box and makes managing entities much easier. I have updated the HA add-on to configure this automatically so people have a one click solution to get eBUSd data into Home Assistant. A couple of observations:

guess the right thing to do would be to set the field name to onoff as well in the inc:43. then it will be picked up by the hassio cfg. if you don't want to change that, then matching it by message name is the right thing to do from my perspective. |

@john30 and what about his first question?
I experience the same issue. And today I had some time to collect more info on it. Log in ebusd shows 20.975 degrees: MQTT explorer value shows 20 degrees: And Home Assistant (obviously also shows 20 degrees): And if you look at the history, you see very clearly when I've upgraded to the new sensors: Any idea what is causing this? I have the feeling that the raw data from ebusd is somehow rounded (without logical rounding rules in place....). |

which ebusd version do you use? there was a fix for such behaviour in 22.2 |

I thought that I was using 2.22 already (since this was indicated in the add-on in HA). But in MQTT I noticed it was 22.1. So I've rebuild the HA add-on and now it's solved. Thanks! |

I too need to control one parameter on my Vaillant boiler so I understand I have to change mqtt-hassio.cfg to allow writes to the ebus. As a non Linux person who is running ebusd as an add-on in Home Assistant under HASSOS, I don't know where to find the correct etc directory from a SSH session. If there's anyone patient out there, please could you advise how to change to filter-direction = r|u|^w . I assume that I will then be able to use MQTT set calls to change the value I want (which is the flowtempdesired |
Beta Was this translation helpful? Give feedback.
-

Hi @losip, it's a shame you have given up on such a powerful tool. FlowTempDesired is the equivalent of d.05 from your installer's menu on the boiler and you can't edit it there either! So maybe your ambition was a bit misdirected? It is however derived from other parameters that you can change like Heat Curve. Maybe start a new thread with what you are trying to achieve and I'm sure the community will help. The problem is this is quite a complex subject - IT/Technology, hydro and thermo dynamics and general engineering! Worst case- If you don't have the appetite to continue, I am sure there will be others on this forum though that would welcome your adapter at cost price though! |
Beta Was this translation helpful? Give feedback.
-
|
You're probably right @JonesGW-MGD . I may be trying to write to the wrong parameter. I just want to do remotely what you can easily do from the boiler itself, i.e. if you press the CH button, then + and - you change the target flow temperature. If I actually do this on the boiler, the only sensor that changes to reflect the setting is FlowTempDesired so I jumped to the conclusion that I just had to write to that. But maybe it's achievable by setting other entities. However, I can see from the config files that none of the entities with the "temp" attribute are writeable by default. I've not yet disposed of the adapter in temper so if you have any suggestions how I can change a setting that the customer is encouraged to adjust, then I would be very grateful |
Beta Was this translation helpful? Give feedback.
-
|
It possibly depends on your heating system setup - do you have an outside temperature sensor? If so, then the thing that controls the FlowTempDesired is the heat curve which calculates the desired flow temperature based on both the desired (room) temperature and the outside temperature. Old boilers may work more primitively than that of course. I believe an alternative approach is to manipulate SetModeOverride - I've not needed to do this but you can search for this in this forum but also the configuration files discussion forum. This might be a good place to start: john30/ebusd-configuration#242 This will involve you adding a new custom message 'SetModeOverride' that will allow you to control flow temp and others - I believe you need to send this frequently even if your desired values don't change otherwise the controller/boiler will reset to defaults after a number of minutes. Good luck! |

|
Thanks for the advice @JonesGW-MGD . No, I have a new heat only boiler with HA controlling the only input which is Heat Demand. HA takes care of when the boiler should heat according to room temperature sensors so it's just on or off. The boiler takes care of the modulation. Your idea of using SetModeOverride sounds promising. I will have to study the forum to determine the syntax to publish via MQTT but FlowTempDesired is certainly one of the many parameters |
Beta Was this translation helpful? Give feedback.
-
|
@JonesGW-MGD I can confirm that writing to SetModeOverride did just what I want, but the boiler reverts to panel settings after 15 minutes as you surmised. This is no problem and perfectly reasonable. If anyone else is wondering, I just had to publish a payload of 0;75;-;-;-;0;0;0;0;0;0;0 to mqtt topic ebusd/bai/SetModeOverride/set to set the DesiredFlowTemp to 75°. I found that with the 5th parameter set to 0, the modulation stuck at the minimum of 22% but it works properly with the fifth parameter set to - Thanks to everyone who helped with advice |

I started using Home Assistant (aka "HA" or "hassio") a while ago and was pretty impressed by its features and huge number of integrations. So I wanted to have all the data grabbed from my heating to be available on my HA instance as well :-)
As the available data in ebusd is highly dependant on the actual circuits on the bus, this had to be done in a very dynamic fashion and luckily HA supports a feature called MQTT discovery. This allows any MQTT capable thing to announce semantics of the data sent though MQTT itself - really cool.
Support for this is now implemented in ebusd using a little template engine which is activated by using "--mqttint=/etc/ebusd/mqtt-hassio.cfg --mqttjson" as additional arguments to ebusd. See the details described here as well.
At the end, it looks like this in HA lovelace for one of the entities:
And the list of entities is huge - this is just the list of devices each one having a lot of entities in it:
All entities belong to logical devices within HA, here is an example one:
How is this activated? Simply by enabling MQTT for ebusd and making it use the integration configuration file, e.g. like this:
ebusd ... --mqtthost my-mqtt-host --mqttport 1883 --mqttint=/etc/ebusd/mqtt-hassio.cfg --mqttjsonThat's it, the magic starts automatically when looking at HA later on.
