Feature Request : Integration of DPT 235.001 / DPT_Tariff_ActiveEnergy

[bbreton09]

Hello, do you think it's possible to integrate the DPT 235.001. Is a 6bytes DPT. This contains DPT 13.010 and 5.006+1 data validity byte.

Thank you

Hi 👋

Currently we don’t support “compound” DPTs as sensors. It would need a quite big change in how HA entity creation works.

Such a feature could also be used for other DPTs like RBG color etc.

[bbreton09]

Hi, it's bad new :'( thank you for quick answere.

[farmio]

It's not like this feature wouldn't be welcomed. It's just that someone would need to find time to implement it.

[farmio]

🤔 thinking about that a little bit more, it might actually be trivial to add support for HA events and services (not sensors / entities). I guess that would be a good start as sensors might get created from templates easily then.

@bbreton09 do you want to start working on that?

Hi @farmio,

Unfortunately, I'm not a developer at all. I can however test things I have a machine with Hass.io and a module that supports DPT 235.001.

Hi @bbreton09,

could you tell me a little bit more about your usecase with this particular DPT? What would you want to do with it?

[bbreton09]

@marvin-w

I have a Hager TX230 module which receive the active energy in kWh via teleinfo. Unfortunately this module uses DPT 235.001. Therefore active energy DPT 13.010 is combined with Tariff DPT 5.006. The goal here is therefore to be able to recover the active energy in kWh to use the HA energy module.

Hi, any news about this DPT ? How can i help ?

Not shure it help but in jeedom KNX plugin the décoding is make like this:

case "235":
	if ($dpt != "235.001"){
	/*if ($value < 0)
	$value = (abs($value) ^ 0xffffffff) + 1 ; */
	foreach(explode('|',$option["ActiveElectricalEnergy"]) as $tarif => $ActiveElectricalEnergy){
	$value=cmd::byId(str_replace('#','',$ActiveElectricalEnergy))->execCmd();
	$data= array(($value>>24) & 0xFF, ($value>>16) & 0xFF,($value>>8) & 0xFF,$value & 0xFF,$tarif,(0<< 1) & 0x02 | 0);
	}
}

			case "235":
				if ($dpt == "235.001"){
					$value = $data[5] & 0x01;  
					if($value == 1)
					   break; 
					log::add('eibd', 'debug', 'La valeur de la énergie electrique est valide');		
					$value=($data[5]>>1) & 0x01;
					if($value == 1)
					   break;
					log::add('eibd', 'debug', 'La valeur du tarif est valide');	
					if ($option != null){
						if ($option["ActiveElectricalEnergy"] !=''){	
							$ActiveElectricalEnergy=explode('|',$option["ActiveElectricalEnergy"]);
							$Tarif=$data[4];
							log::add('eibd', 'debug', 'Nous allons mettre à jour le tarif '. $Tarif);	
							$ActiveElectricalEnergyCommande=cmd::byId(str_replace('#','',$ActiveElectricalEnergy[$Tarif]));
							if (is_object($ActiveElectricalEnergyCommande)){
								$valeur =$data[0] << 24 | $data[1] << 16 | $data[2] << 8 | $data[3] ;
								if ($valeur >= 0x80000000)
									$valeur = -(($valeur - 1) ^ 0xffffffff);  # invert twos complement    
								log::add('eibd', 'debug', 'L\'objet '.$ActiveElectricalEnergyCommande->getName().' à été trouvé et va être mis à jour avec la valeur '. $valeur);
								$ActiveElectricalEnergyCommande->event($valeur);
								$ActiveElectricalEnergyCommande->setCache('collectDate', date('Y-m-d H:i:s'));
							}
						}
					}
				}

Hi 👋! No news on this front. The first answer to this issue still applies. Parsing the payload is not the problem - handling the result down the pipeline in xknx devices, HA entities, services and events etc. is.

[bbreton09]

Thank you ! Do you know how many time is take to this update is include in haos ?

[farmio]

It will need some changes in the integration code and the frontend too. And some testing would be good too. So definitely not in the coming release (that's in 2 days).

I did plan to release this as part of a bigger (breaking) change to xknx.

Hi, thank's your work ! I saw XKNX 3.0.0 with DPT 235.001 is release. Is he also available in HA 2024.8 ?

[farmio]

Yes 👍

[bbreton09]

Yes 👍

What type should I use ? I try TariffActiveEnergy, DPT-235.001 but HA say error

https://www.home-assistant.io/integrations/knx/#sensor

[farmio]

It is not supported by the sensor platform. Only by triggers (knx.telegram or interface device), actions (knx.send) and group monitor.

It should be possible to create a trigger based template sensor with that. https://www.home-assistant.io/integrations/template/#trigger-based-template-binary-sensors-buttons-images-numbers-selects-and-sensors

Ok, try to read in group monitor but return is null. In ETS i assign DPT 235.001 to Address Group and upload to HA.

[farmio]

Seems like the value is marked "invalid" 🤔 https://github.com/XKNX/xknx/blob/main/xknx/dpt/dpt_235.py#L19 See the screenshot in the initial post here.

Hi, this is the log knx when receive value with DPT 235.001. I alway have null value.

@farmio @bbreton09 : for information I opened a PR to fix this https://github.com/XKNX/xknx/pull/1685

[Foulek94]

Bonjour, je suis novice dans la programmation de HA mais j’ai quelques compétences en KNX (KNX Partner). L’évolution de XkNX permet maintenant de décoder le DPT 235.001 au niveau du groupe monitor KNX. Est-ce qu’une personne pourrait m’indiquer la marche à suivre pour créer correctement le sensor afin de pouvoir l’intégrer dans l’énergie ?

Lorsque j’indique le type ou le numéro de DPT, HA refuse l’entrée indiquée.

Merci !

@Foulek94 Hi 👋! See https://github.com/XKNX/xknx/issues/1108#issuecomment-2278261126 You can use the knx.telegram trigger for a template sensor.

[Foulek94]

@farmio Hi,

Thank you for your reply. Could you please send me an example of YAML code that I can use to create this?

[farmio]

Something along the lines of state: "{{ trigger.value.energy }}" but I never tested that. You'll probably find similar examples in the template documentation linked above.

I'd use a helper created in UI instead of pure yaml 😉
