Hello everyone. This month I started the development of an opensource application for the acquisition of meteorological data in developing countries.
The datalogger is composed of a Raspberry PI with Ubuntu and WEEWX installed on using the Python tool setup.py. The developed software periodically read the ambient data (temperature, pressure and so on ...) from different sensors, prepare a text file read by WEEWX (for flexibility reasons, the acquisition software pass data to WEEWX, using text files read by fileparse driver). Finally, WEEWX collect the physical quantities in a Sqlite3 database and create reports. During the development period I have already solved various problems encountered, by carefully reading the documentation and several posts in this forum. Unfortunately, I'm finding problems about the ability through WEEWX to manage an optional sensor (a commercial water sensor level, used to acquire the water level in a river) and then ask for help. Actually, my software collect data from the sensor level correctly, and I want to pass these values to WEEWX. Since it is an optional sensor, I had thought of managing the sensor data using a different WEEWX process, passing the data to the fileparse driver to store them in the weewx SQLite3 database. I have an even limited experience on WEEWX, so I still don't know how you could correctly configure the program to manage the 3 variables read by the sensor: 1. "temp": the external temperature measured, in celsius degrees 2. "'Battery_SOH": battery state of health, a percentage value that represents the charge status of a non-rechargeable battery. It is necessary to monitor the charge status to check when physically change the battery. 3. "'level": distance of sensor from water, in centimeters For example, In base of weewx documentation (particolarly, [WeeWX: Customization Guide](https://www.weewx.com/docs/customizing.htm#aggregation_types)), I see that I could assign the sensor temperature to outTemp, but I don't know what standard weewx variable (corrispondent to a column of the sqlite database) I can assign to "Battery_SOH" and "level" and to also draw the graphs using the configured skin. What are the steps I need to follow to configure weewx correctly in this case? In particular, there are numerous WEEWX variables that can be used to monitor sensor power supplies, but the measurement units are expressed in Volts. In my case, Battery_SOH is expressed with a percentage value of full charge. Thank's for collaboration.
