It seems this does not work for GUI-applications (e.g. gitkraken, transmit) using ssh-agent in the background.

For this, adding a .plist for launchd seems to be working:

@ronaldvdmeer this works up to line 335, I don't have Domoticz running so I can't test the rest.

Note that this still over-queries the meter in case you want to run multiple operations on the same index, e.g. the example command queries the meter 3x. Perhaps you could cache the values for all indices the users wants, and then run the Domoticz operations.

Command:

/usr/bin/python3 ./multical402-4-domoticz.py /dev/ttyUSB0 327:60:2:323,322:60:1:323,323:60:0

Output:

Thanks for your PyKamstrup port for Multical energy meters! When adapting this for influxdb, I noticed you are superfluously querying your energy meter, thus depleting the battery faster than needed (up to 30x more than needed).

You loop over all (30) multical variables here and query them, but only parse the ones issued on the command line (~1-2?), see: https://github.com/ronaldvdmeer/multical402-4-domoticz/blob/f6aa7b9351a0f37fa265f68b05417e01586851b0/multical402-4-domoticz.py#L315

To fix, only loop over command line variables or only query the sensor in the inner loop.
