I am trying to use the actuator agent to write to a building automation point with set_point. This is the a snip from my Python code:
_log.info(f'{log_prefix} - meter_topic: {meter_topic}')
_log.info(f'{log_prefix} - self.electric_meter_value: {self.electric_meter_value}')
self.vip.rpc.call('platform.actuator',
'set_point',
self.core.identity,
meter_topic,
self.electric_meter_value
).get(timeout=300)
This is the traceback in my volttron.log file:
2023-09-28 20:10:26,482 (rtuloadshedagent-0.1 49669) __main__ INFO: [WRITE POWER METER VAL INFO] - meter_topic: 500001/input-power-meter

KeyError: '500001'
This is how the points are defined in VOLTTRON but unsure why I get the error? Unless its looking for this longer full string devices/slipstream_internal/slipstream_hq/500001. Any troubleshooting tips appreciated.
vctl config store platform.driver registry_configs/500001.csv registry_configs/500001.csv --csv
vctl config store platform.driver devices/slipstream_internal/slipstream_hq/500001 devices/500001
You are correct, so it is looking for "slipstream_internal/slipstream_hq/500001".
vctl config store <vip-id> <config_name> <config_file>
It is interesting, as you must have a file at ./devices/500001 or the vctl store command would have produced an error.
