SML with two Engelmann WMZ / Heatmeter via wired MBus and TTL-MBus Adapter

[Stephan2204]

Hi, i have programmed both heatmeters with different addresses (1,2). So both meters could be connected to the same bus.

Basic Script will read one of them by changing the address:

>D
wkup=1

>B
;setup sensor
->sensor53 d0
->sensor53 r

>S

>M 1
+1,3,rE1,0,2400,MBUS1,1,10,107B017C16 ; 01 7C -> #1  // 02 7D -> #2
1,=so3,128
1,=h Heizkreis 1
1,0478u32s@1,Zählernummer,,Zählernummer,0
...
#

So SML is working fine and could send the right frame and Data will be retrieved to Webinterface and send via MQTT.

Then i have extended the script to two meters:

>M 2
+1,3,rE1,0,2400,MBUS1,1,10,107B017C16 ; 01 7C -> ##1
1,=so3,128
1,=h Heizkreis 1
1,0478u32s@1,Zählernummer,,Zählernummer,0
+2,3,rE1,0,2400,MBUS2,1,10,107B027D16 ;  02 7D -> ##2
2,=so3,128
2,=h Heizkreis 2
2,0478u32s@1,Zählernummer,,Zählernummer,0
...
#

Now it's confusing...
Only the Values of MBUS1 in the Webinterface (and MQTT) will be filled by ##1 and switching every 10 seconds to show ##2 and back...

MBUS2 Entries stay 0.

I have also tested the script with the ##readmeter and different sml command:

sml(1 1 "1040004016")
delay(350)
print request current data (107BFE7916)
sml(1 1 "107B017C16")
delay(1000)
print request current data (107BFE7916)
sml(2 1 "107B027D16")

But this is not working too.

Seems that anyhow the SML Code will not give the right id of meter back to the function for filling the values into vars.
A short look into the sourcecode for sml confused me more. Its to long ago for my C-phase of life.

Add:
if i work with M1 and give both addresses, its the same..... switchting values of the meters in the WebIF.

>M 1
+1,3,rE1,0,2400,MBUS1,1,10,107B017C16,107B027D16
