Bosch/Junkers Heizung mit MB LANi/MB LAN2 anbinden

[grappa24]

Hallo,

ich stehe vor der Auswahl einer neuen Heizung, aktuell Bosch/Junkers als Angebot. Kann man denn ein Bosch/Junkers Internet-Gateway über FHEM ansprechen?

Grüße, Dieter

ich präzisiere mal:

Es geht um eine Junkers Cerapur ZSB 24-5 mit CT200 Regler (EMS 2 Bus).

Mit dem CT200 kann die Heizung a) direkt und b) via Internet angesprochen werden.

Darf ich das mal aufwärmen? Ist die Antwort "nein" ?

The MBLAN module is the same than Buderus KM200 and is supported on fhem. see here : https://forum.fhem.de/index.php/topic,25540.0.html

On other hand it is possible to connect a small board to the ems bus and have control on it over MQTT.
I'm currently setting up this in fhem

look there for the board : https://github.com/proddy/EMS-ESP

and  the suport thread for it : https://forum.fhem.de/index.php/topic,104968.0.html

thanks moustic999!

I heard about this board before, but I'm not experienced enough to build one by myself; is there anyway to order/buy this board "ready to use"?

[moustic999]

yes kees build and sell them : https://shop.hotgoodies.nl/ems/

wow, just what I've been looking for for months ... 

*** out of stock at the moment ***

just received my EMS-gateway from Kees yesterday 
- easy integration in my network
- MQTT2 server in FHEM defined
- MQTT on EMS-gateway enabled
- definition of an MQTT2-device via autocreate - very comfortable
- automatic generation of suitable readings via readingList - very comfortable
- just played with grafical presentation of curFlowTemp - love it ...

- now looking for an example to use the setList attribute ...

share your config and trials in the appropriate topic :

we are busy with creating a template to support EMS-ESP

[grappa24]

I read the ems-esp MQTT thread several times, but I'm not sure whether You are still working on a template to support EMS-ESP or if there is already a template ready to use?

I'm quite familiar with the ems-esp "readingList" of my junkers boiler but not with changing state oder readings.

If I can provide any expamples concerning my CT200 let me know.
