I bought this off ebay:
DVB-T USB TV FM+DAB Radio Tuner Receiver Stick Realtek RTL2832U+R820T MCX
Cost me $10 w/ shipping.
I’ve got the data in MH with a custom perl script that I run in the background (below). Now I’m just creating per minute totalizers for the deltas and I can use the new RRD object method to log the minute by minute changes. That should give me the daily usage patterns (I hope!)
#!/usr/bin/perl
my $host = "127.0.0.1";
my $topic_root = "utilities";
my $debug = 0;
my %mqtt_obj_name;
$mqtt_obj_name{30273954} = "water_meter";
$mqtt_obj_name{45275962} = "gas_meter";
$mqtt_obj_name{3442387} = "power_meter";
open (RTLAMR, "/usr/local/bin/rtlamr -server=127.0.0.1:1432|");
#my $var="{Time:2021-05-23T12:57:52.339 SCM:{ID:30273954 Type:13 Tamper:{Phy:00 Enc:00} Consumption: 224471 CRC:0x5689}}";
while (<RTLAMR>) {
chomp ($_);
print "** $_ \n" if ($debug);
my ($id, $type, $consumption) = ($_ =~ /ID:\s*(\d+) Type:\s*(\d+).*Consumption:\s*(\d+)/);
my $topic = $mqtt_obj_name{$id};
if ($topic) {
print "mosquitto_pub -h $host -t $topic_root/$topic -m \"$consumption\"\n" if ($debug);
system "mosquitto_pub -h $host -t $topic_root/$topic -m \"$consumption\"";
} else {
print "unknown ID $id\n" if ($debug);
}
}
