In this version, we used a shunt resistor of 2 ohms, which limits the current measurement to 48 mA. If the current is higher than this value, you just have to decrease the value of the shunt resistor. Don't forget to change the shunt value in the config.py file (value associated to key 'R_shunt' in the OHMPI_CONFIG dict).
Loggers have been introduced in this release. They use the excellent logging python package.
Specific handlers have been implemented for running with ohmpi.py (one for logging to an mqtt broker (see `MQTT interface`_ for more details) and one for creating zipped rotated logs on disk.
Two loggers have been defined. The first one is dedicated to log operations execution. It is named exec_logger. The second one is dedicated to acquisition data. A third one is planned to log state of health data (SOH) in a future version.

In the default version, logs are written to the console (print-like), stored locally in files (a zip is created after some time i.e. every day and/or when the size of the log exceeds a maximum size) and sent to an MQTT broker. Different logging levels may be defined for the different logs and handlers in the `Configuration file`_.

Advanced users may write new handlers and edit the `setup_loggers.py` file to customize the logging mechanisms to their needs.
