Hello immi,

yes

I updated fhem - now I'm getting following Messages in the log:

Hi fabian

Hi immi,

I've been using you code for years now, and the only thing I've noticed is I'm getting older 

Beautiful work.

I do not know THZ protocol well enough, so I thought I would ask here: is there an option at all to switch fireplace dependency remotely, ie. via code, not via control panel? In certain conditions I would like compressor to automatically work regardless of fireplace already engaged - because then I can "ask" THZ to focus on DWH, and fireplace on floor heating.

Sorry if asking about obvious.

thanks for the compliments
I have no experince with fireplaces  and thz
as far as I remember nobody reverseenginnered the code behind
if you have a 4.xx firmware you can use the attribute

Code Auswählen Erweitern

attr Mythz firmware 4.39technician
here you can start/stop the 2 pumps manually
zPumpDHW
zPumpHC
pay attention to possible sideeffects that could happen to you tecalor

My pump reports version 4.38,  so I will try. Thanks!

But take care. You MUST NOT switch off both pumps the same time while compressor and/or booster is active. Otherwise the THZ could be damaged by overtemperature.

i own a tecalor 304 eco with firmware 5.09
if i want to set p75 (passive cooling) i am only able to set 0,1 or 2.
if i read p75 via the get method i get "4" which is linked to "sommerkassette".
could this thing be fixed in a next release?
Thanks

Do you have installed a "Sommerkassette"?
If you have not bought it yet but think of buying one, you should first read my posting about effects of "passive cooling" here: https://forum.fhem.de/index.php/topic,33452.msg644327.html#msg644327
Spend your money on something else but not a "Sommerkassette".

Hi Spirit
have you tried the attribute firmware 5.39?
if you do not set any attribute you fall back to default, firmware 4.39

i was not aware of this attribute.
will give it a try today.
thx

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.

[willybauss]

I never tried it, just the minutes. For me that's sufficient, since I just want to synchronize times. Daylight saving time is done automatically by THZ display setting.

I know; I also use your "at" for time-synchronization.

Nevertheless I wanted to try to skip the automatic "reset" at 10:00am today.
When I had a look on the plots a few minutes after 10 I first thought it works. When I checked the log-file I found a syntax-error in my "at", so I checked sTimedate and saw that only the minutes were changed.
Then I tried to change the hour directly in THZ, but it did not work.

Anybody else who tried it?
Maybe willy you give it a try and check it?

[willybauss]

tried changing clock hours in display => works
tried changing clock hours in fhem => does not work, just reports act. hour
tried changing clock hours in display again => still works

Okay, so then it affects both x03 and x04 and is also not related to firmware-attribute 5.39.
