More info

I do own a Kamstrup 401. Is this integration also working for Kamstrup 401?

A long time ago I did write some code in Python on a RPI to read the Kamstrup 401. maybe it is something for you to help?

nietklaar = True
MaxPogingen = 5
Poging = 0
print "Data Kamstrup inlezen"
while nietklaar and Poging < MaxPogingen:
    if DebugAan: debug("Poging ", Poging, True)
    mc401.baudrate = 300
    mc401.write("/#1")
    mc401.flush()
    sleep(1)
    mc401.baudrate = 1200
    mc401.flushInput()
    data = mc401.readline()
    data = data.strip('#/n/r')
    data = data.split()
    nietklaar = False
    print "Poging : ", Poging
    if DebugAan: debug("Ruwe data meteen na inlezen: ", data, True)
    if DebugAan: debug(" -- Lengte van data : ", len(data), True)

    print "Data: ", data
    Poging = Poging + 1
#   data = ['10282250', '2267172', '0079692', '0007299', '0002800', '0004499', '0000134', '0000255', '0000242', '0000000']  # test string
    if (len(data) == 10  ):
        for index in range(len(data)):
            if (len(data[index]) <> 7):
                ts = time.time()
                st = datetime.datetime.fromtimestamp(ts).strftime('%d-%m-%Y %H:%M:%S')  # Lees de tijd in
                if DebugAan: debug("st =  ", st, False)
                if DebugAan: debug("Lengte klopt niet van data nr ", str(index) + " data = " + data[index], True)
                print"Lengte klopt niet van data nr ", index, " data = ", data[index]
                nietklaar = True
#               sleep(26) # initiele waarde
                sleep(5)
                break
        if DebugAan: debug("Lengte klopt van alle data ", "", False)
        if DebugAan: debug(" - nietklaar = ", nietklaar, False)
        if DebugAan: debug(" - MaxPogingen = ", MaxPogingen, False)
        if DebugAan: debug(" - Poging = ", Poging, True)
    else:
        if DebugAan: debug("aantal woorden data klopt niet", "", True)
        nietklaar = True

I don't think it does, the code looks different. The simplest for you to do is install this component and try it out.
