Domoticz

Hi All,

I have a Kamstrup Multical 601 for heating and warm water usage counting, but I cannot get any data out of it.

I'm trying to read it using an IR cable. I used this cable before for my ISKRA171, so the cable works fine.
Problem is, I cannot get any data out of the Multical.

I read all topics about Multical 401/66C, but the software used for this gives no response at all.
I know the meter can be read, because an engineer of the heating company used an (official) IR dongle to read the meter.

Has anyone used a Multical 601 in Domoticz succesfully?

Ok, I'm communication with my 601 now.

Turns out the /#1 etc. commands do not work on the 601 (unless you have a special module allowing for these).
You have to communicate with the multical using the KMP protocol.

This code on github is working for me:

Currently I'm experimenting with the available commands.
The commands for the Multical 601 can be found in the Multical 601 technical manual that you can download from the Kamstrup site.

Other changes I needed to make:
- Set the serial port to the correct value (for me /dev/ttyUSB2)
- Set the baud rate to 1200

Got it working in Domoticz now.

I'm using the gas sensor, because no heat (GJ) sensor is available.

Can anyone with a another multical (401 or 66) test if the script works for them?
This might be a more generic method to reading Kampstrup meters than using the other method.

For heat energy you can use code:
0x003C: "Heat Energy"

Hello,

How did you set it up in domoticz. Did you use a dummy gas of P1?

Greatings,

Mark
