missing shower_data

[stmb-100]

Hi
I get no Shower_Data in my IO-Broker. This is how I configured it.

That's all I see in the log file : [mqtt] Publishing topic ems-esp-33/shower_active (#62442, retain=1, retry=1, size=5, pid=1)

This value has not changed for a few days, even though people shower several times a day. I can't say if it's ever been different.
How to narrow down the problem

Regards
Stefan

Shower detection only works with flow-systems, dhw buffer-systems does not have a flow sensor. Check in boiler data what type your system is: My boiler shows:

[stmb-100]

Hi my dhwType is flow

[MichaelDvP]

Do you see nonzero values in dhw current tap water flow (wwcurflow) when tap water is used?
What is tapwater_active showing?

[stmb-100]

[MichaelDvP]

Is it really a flow system? How do you manage flow with solar? Solar needs a buffer and in case of no sun the buffer is charged by boiler? Or do the solar heated water flow though a boiler heatingblock and burner starts if it is colder than required? tapwateractive and shower-active are ony triggered when burner is started in dhw mode.

Or do the solar heated water flow though a boiler heatingblock and burner starts if it is colder than required? It could be but I'm not sure how to find out

Hi
GERMAN : (Könnte hier ein Zusammenhang mit dem Fehler A01/811 bestehen, den ich bei aktiver thermischer desinfektion bekomme)

Could there be a connection with error A01/811, which I get when thermal disinfection is active ?

GERMAN:
Diese Meldung wird erzeugt, wenn 3 Stunde nach Start der thermischen Desinfektion die Solltemperatur für die thermische Desinfektion nicht erreicht wurde.
AUSWIRKUNG : Nach der Fehlermeldung wird die thermische Desinfektion abgebrochen

This message is generated if the target temperature for thermal disinfection has not been reached 3 hours after the start of thermal disinfection.
EFFECT: After the error message, the thermal disinfection is aborted

[MichaelDvP]

I really don't know.
The dhw-system is fixed in boiler, so flow type is right. I have no experience with flow systems, but imo it needs a flow sensor and wwcurrflow should have a value if water is running.
Maybe @proddy can help, afaik his system is also flow type.

[proddy]

yes I have a flow type too. When the hot water is running see if the "current tap water flow" value changes.

[stmb-100]

Hi
I don't think that the value changes during hot water flow, why it changes on 3.8. I don't know.

[proddy]

3.8?

[proddy]

is this still an issue?
