A IAMMETER Energy Meter may be monitored. Only the single phase meter is supported at this stage.
The IAMMETER meter is configured in the YAML configuration file as:
#
# iammeter configuration
#
iammeter:
meter: <url to retrieve data>
poll: <polling interval in seconds>
offset: <polling offset in seconds>The meter URL is usually of the form http://user:password@<meter>/monitorjson
where <meter> is the host name or IP address of the meter, and the default user and password
is admin:admin.
The default polling interval is 30 seconds, and default offset is -5 seconds
The values read from the meter are the voltage, current, power (import or export) and total export and import energy.
