You can also store your data indepently and let weewx fetch it every 
archive interval. For instance, I have solar energy on the roof of my 
house, the inverter logs and stores all the data. The inverter has a REST 
interface and weewx fetches this data and stores it every archive interval 
and plots a nice graph. Sine my wheater station doesn't have radiation 
measurement, the amount of solar energy produced lets me guess how the 
sunlight conditions are at my place. 

here is how something like this could look like:

of course!

one option would be to use a gw1000 and various soil moisture sensors and 
temperature/humidity sensors

this wiki page explains some of the data collection strategies:

https://github.com/weewx/weewx/wiki/intake-strategies

this wiki page explains some of the ways to aggregate the data into 
dashboards:

https://github.com/weewx/weewx/wiki/dashboards

start with a diagram of the physical locations of the things you want to 
monitor.  then create various overlays to sketch out different logical 
structures for how you might install and configure the data collection.  
from the other end of things, sketch the data display as you would like to 
see it - graphs, tables, current/min/max indicators, etc.  with those 
pieces you will be better prepared to implement something. it will also 
make it easier for you to communicate with others when you have questions 
or when you want to share what you have done.

i typically have a weewx instance at each data collection point, with a 
very basic weewx skin that i can look at to see if data are coming in 
properly.  then i configure each weewx instance to send data to an mqtt 
server or influxdb server.  at that point i can use grafana or other tools 
to create multiple dashboards, each oriented toward the user(s) who need 
access to the data.
