Hi Koppl
happy you did it,
would you be so nice to improove http://www.fhemwiki.de/wiki/Fhem_on_OS_X with your usercase?
just write down a proposal and give it to a wiki admin to upload
we do not want all this info to get lost. some other users could need it.

[micomat]

you can send a proposal to me, i can add it to the wiki.

[Koppl]

hello,

yes I write a proposal and send it micomat.

One problem I have.
I like described in the wiki added to the FanSelector for ventilation control.
The ventilation is not around.
How often FHEM reads the data from the heating and sends it back?

The readings will be properly time when I compare.

Thank you

[immi]

How often FHEM reads the data from the heating and sends it back?

I do not understand your question.  There are parameters for thelling fhem how often to read.
Have a look at this example: start simple and when you understand better fhem, let your config grow.

Willy, Markus, Tom ... have much better, fancy configuration. Maybe they will show you the real potential of FHEM.

I posted my whole configuration including screen dumps inside this thread, approx.April time frame. Nothing changed meanwhile, still works.

nice effect of switching off daylight savings (see attached jpg)

yep back to the past!

im "Event Monitor".
Liegt das vielleicht am BananaPi oder muss ich da was in der fhem.cfg
eintragen? Hab das zwar über die Suche an verschiedenen Stellen gefunden,
aber leider keine Lösung.

hi Gerry
is the Connection down or do you just dont want to See this messages?
i See then also but Connection is Fine. do you use serial or USB?

[gerry.s]

Hi Micromat,
Connection is fine, but my web interface is very slow and I thought that's because of the log traffic. I use direct USB connection.

[micomat]

okay we See this issue on USB. Mine is also not sooo fast but this may also depend in the number of data read from the thz. this error may occur to electrical interferences.
should be no Big Thing.

If your system is normally working and  you get such a log sporadically, like Markus, I expect an interference problem.
Someone correlated problem with some events in the heatpump.
I do not have your configuration, therefore I cannot go systematically to the root cause.
I would try to stabilize the current supply and in parallel build some kind of emc-filter or magnetic shield.

If your system is reacting slowly, it could be related to the huge ammount of data you can generate in FHEM.
Post more information as attachment: config file, plot files, logs... maybe someone can help you.

I am wondering how to interpret the physical meaning of the parameter sHeatRecoveredDay with respect to the calculation of the COP. Is it already included in sHeatHCDay (sHeatHCDay = sHeatRecoveredDay + <energy transferred from outside air>)? Considering the logged values it would be my guess. Today's values are as follows:
sHeatHCDay = 38858 Wh
sHeatRecoveredDay = 12227 Wh
sElectrHCDay = 10313 Wh
(no boost)

Though, the sum of the electrical values (incl. boost) does not match the metered values. The THZ reports approx. 200 kWh less than the meter.

Cheers!
