Issue with multiple TCMs

[tomaszG]

Dear all,

I am trying to use several TCMs on a single RPi and it is not working for me.
I connected to TCM 310 on a RPi3 with FHEM and create the devices with

Code: [Auswählen]

usb create command. Until there it looks fine, both TCM are initialized after a reboot
I can pair  no problem on the first TCM

Code: [Auswählen]

TCM_ESP3_0 some devices (EEP A5-20-04 Manufacturer: Holter Regelarmaturen GmbH) and it is working fine. But on the second TCM

Code: [Auswählen]

TCM_ESP3_1, it fails with the following log messages

Code: [Auswählen]

It is not recognizing the kind of device apparently. The same device I try to pair on 2nd TCM can be paired on 1st TCM so the problem is not the device but the TCM.

Any ideas what to do to debug / solve the issue ? Any known problems with multiple TCMs ?

I am still looking for hints on this. Please point me to anything useful.

I believe that there is no simple solution. As far as I know, enocean is not designed for multi-transmitter operation.
Some hints can be found in the (german) thread: https://forum.fhem.de/index.php/topic,35118.0.html

Hi,

Thanks for the input. I think this points me in the right direction, but it indeed seems problematic.
I will recap because I am not certain I got exactly all the details of the discussion between klaus.shauer and Schmitzkatze.
What I understand is there seems to be a problem in having several TCMs on the same RPi due to confusion in identifying which transmitter should be used to receive and/or send messages.
For incoming messages, this was partly solved thanks to the fingerprint feature from thread https://forum.fhem.de/index.php/topic,75291.0.html
But for bidirectional devices (like mine), there is a more important problem.
I did not really get if some extra manual configuration could help solving this though.
