THZ Tecalor (LWZ Stiebel Eltron) module support and code improvement.

Has anyone ever tried setting "pClockHour" with FHEM?
I tried it, but it's always returning the actual hour and does not change the time.
"pClockMinutes" seems to work properly.

I just googled
https://forum.fhem.de/index.php/topic,33211.msg260851.html#msg260851
toggle found out the registers.

So then maybe toggle can cross-check if changing the hour (still) works.

Hi Andre
would you mind xchecking line 820?
"sControl"           => {cmd2=>"F2", type =>"F2type", unit =>""},
why it is defined F2type?
actually line 820 can be deleted, because sControl already in %getsonly2xx.
thanks immi

Hi,

looks like I found the "humidityAirOut" (Abluftfeuchte)in sGlobal (and on the way to there a couple other parameters as well. The other values appear to relate mostly to the P and B sensors from the electrical circuit layout from the installation manual. FowRate in sGlobal is returned as value when the parameter is not shown as a favorite ...).

On my device (304 integral SW 5.09) teh "Abluftfeuchte" is always displayed as "0" on the iPod display, so I could only do an indirect sanity check (increasing / decreasing humidityMin in humidity protection in order to trigger / untrigger the ventilation output decrease) - may be some one with a device where "humidityAirOut" is displayed can verfiy ...

hi    LeJoke
thanks for sharing, I will test this night or tomorrow: I am the whole week on the seaside.

Also my display always shows it as "0", but I have an external sensor just before the LWZ. Attached you'll find the comparison of external sensor and your reading. It's definitely the "Abluftfeuchte". Well done!


One more point:
Did you change the order of the readings in "sGlobal"?
I've just overtaken your code, today's DHW-cycle shows useage of "booster-stage 1" although it definitely was not activated.

Are you sure you uploaded your changes?
I just did an update, but sGlobal is unchanged.

EDIT: Just crosschecked https://github.com/mhop/fhem-mirror/blob/master/fhem/FHEM/00_THZ.pm, it's unchanged there.

it takes up to 12h for git and the fhem update function to sinc from fhem original repository

... sorry, not on purpose, but you are right - I had accidentally posted a sGlobal where the previously known parameters were mostly reordered according to their position in the response string ...

Today in the morning I tried another FHEM-update, now immi's new version is there. He already took care about the order of the signals.

[andre.k]

Hi Andre
would you mind xchecking line 820?
"sControl"           => {cmd2=>"F2", type =>"F2type", unit =>""},
why it is defined F2type?
actually line 820 can be deleted, because sControl already in %getsonly2xx.
thanks immi

hi immi,
sorry for my late answer.

And yes the line with F2type can be deleted. I'm not 100% sure, if the register F2 is implemented in all 2xx versions.

[TheTrumpeter]

Hi immi,

Just found out that the following two parameters are limited to 28°C in FHEM, but THZ/LWZ-limit is 30°C as per manual:
p01RoomTempDayHC1
p02RoomTempNightHC1

Would you mind changing that during your next revision?

as usuall it should be availabe tomorrow
