HM-CC-TC Readonly access from FHEM with HM-CFG-LAN

[davidm]

I have Six HM-CC-TC all connected through a HM-CFG-LAN to a raspberry pi.  All seems to work ok, except that the HM-CC-TC devices are all "read only" i can't change their mode or set a desired temperature. I have read that there is some contention between HM-CFG-LAN and FHEM, but can't understand where this exists (i'm using google translate for German!).  I have turned off the AES on the HM-CFG-LAN and updated firmware all OK.  I can connect to it using the HM-CFG-LAN software, but have not paired any HM-CC-TC directly with the HM-CFG-LAN. I had one paired in the past, but I removed it and now i can't seem to pair any at all

I have some switches operating the boiler, which I can control just fine with the FHEM so two way comms is working over the HM-CFG-LAN

I'd be grateful if someone can explain;
1) Do the HM-CC-TC need to be paired with HM-CFG-LAN?
2) Do the HM-CC-TC need to be in Central mode (this does not seem to be an option offered on the HM-CC-TC to me at the moment)?

Thanks for any help.

Hi davidm,

1. You need to pair all devices you want to control with FHEM. If pairing fails try to reset your HM-CC-TC.
2. I dont have any HM-CC-TC. Afaik all modes work with default reg settings.

Hi Davidm,

to pair the TC (basically any device) you should

set <hmlan> hmPairForSec 300
=> press config on your Device (ok-button for 20 sec).
If paired you will have the "cent" option in the TC - clicking thru with 'menu-button'. If this mode is not available pairing ist not successful - you have to repeat.
All FHEM (all central-controlled mode) start with pairing the devics for HM.
You might(should) also pair the VDs, SCs (actually all devices)

After pairing you can control the TC from remote. Set week-program, set modes... take a look at
get tc regList
get tc_Climate regList
get tc_WindowRec regList
....

The TC will only take temp-settings from remote in a proper manner if it is in cent-mode. Others are not permanent (especially in manu-mode). Setting temp-lists ist possible for sure.

Many Thanks to you both and particularly for your full answer - this has fixed my problem.   For some reason I has assumed the hmPairSec was just extending a time out.  All works well for me now.

Thanks again.
