Can you see the MBUS ID on the LCD? The address in emonhub needs to match the ID of your meter. Alternatively, you can use this script to set the ID to 1:
python3 /opt/emoncms/modules/usefulscripts/mbus/./mbus_set_address.py
With the ID set to 1 the following config shuld work:
[[MBUS]]
Type = EmonHubMBUSInterfacer
[[[init_settings]]]
device = /dev/ttyAMA0
baud = 2400
[[[runtimesettings]]]
pubchannels = ToEmonCMS,
read_interval = 10
validate_checksum = False
nodename = MBUS
[[[[meters]]]]
[[[[[heatmeter]]]]]
address = 1
type = standard
