How to send data from Homematic to TA.CMI?

Hi there,

I’m just starting to investigate OH 1.x. My home is fully equipped with HM temperature sensors in every room that control the floor heating circuits using a CCU2. The heating is controlled by Technische Alternative UVR 16x2 / CMI.
My plan is to combine those 2 worlds with OH.
I managed to bind the room temperature to items in OH. Some temperature values distributed by the UVR are published using the CMI CoE feature. I successfully bound them to items in OH.
Actually what I need is the other direction: I need the room temperatures in the UVR. Due to very restricted programming knowledge I did not find a way to set the items sending data to the CMI/UVR to values coming from the Homematic items.
What I tried is something like
import org.openhab.core.library.types.*
import org.openhab.core.persistence.*
import org.openhab.model.script.actions.*

rule “roomtemperature”

Item HM_Temperature changed
CMI_input = HM_Temperature

This is obviously not the correct syntax. Could anybody help me out ?

Hi Patrik,

I am starting to work on the same subject, Have you been successful with the integration already?
