Vaillant EBUS

[arudomoticz]

I have a working Domoticz environment on a Raspberry
With the USB RFXtrx433E USB 433.92MHz Transceiver I can read all my Oregon Temperatures and log them

I also have now a Raspberry with a working EBUS environment.
I use the eservice-online ebus-koppler-usb and the ebusd drivers (from john30)
If I start a telnet localhost 8888 session, then with the command "r -f roomtemp" I receive the message "21.50;OK" in Telnet

In which way can I put the value of the roomtemp from my Vaillant Calormatic 470 in Domoticz and log them?

You can use a dummy device and fill that with a json call to domoticz (see wiki for last part)

hi,
could you please show me some picture and give me some more information how you did this?
I also have a vaillant heater and would be able to do the same as you.
Thank you!

Thanks PVM for your reply, due to some circumstances I had a lack of time to continue this project before.
Now starting again to try to make it happen.

I have read the JSON part ad tried the following after making a dummy temperature-sensor
http://192.168.178.135:8080/json.htm?ty ... alue=21.50
Result is OK and my sensor goes to 21.50!

Thats the manual part...
But how I can read it from the EBUSCTL and writeback to DOMOTICZ ?
Must I use a LUA script, do you (or somebody) have a code example?

telnet localhost 8888 session, then with the command "r -f roomtemp" I receive the message "21.50;OK" in Telnet
or at SSH
ebusctl -p 8888 read roomtemp I receive the message "21.50;OK" in SSH

Please can you explain how you do this ?

Does your koppler is on the same wire than your room thermostat ?

Hi, I am using https://blog.sanghera.me.uk/vaillant-eb ... utomation/

Everything works manually.

telnet localhost 8888 session, then with the command "r -f roomtemp" I receive the message "21.50;OK" in Telnet
or at SSH
ebusctl -p 8888 read roomtemp I receive the message "21.50;OK" in SSH

So Ebusctl works AND Domoticz works, but how can I pass values from Ebusctl to Domoticz?
So how do I get the "21.50" in Domoticz?

Must I use a LUA script, is there somebody who can help me with a code example?

You could make a bash script like

#!/bin/bash

TEMP=`ebusctl -p 8888 read roomtemp | cut -d\; -f1 | cut -d\" -f2`

echo $TEMP

curl -s "http://127.0.0.1:8080/json.htm?type=com ... ice&idx=[b]IDX[/b]&nvalue=0&svalue=$TEMP"

Hello, I made a ebusd plugin here: viewtopic.php?f=65&t=20625
