To start, mostly to see what kind of quality I can expect, I decided to build the Pimoroni kit for a pirate radio.

This page collects some tips/suggestions/FAQ to easy deal with this great program.

fHelper - MQTT edition

Ok, time to sum up this version of fHelper project.

After a series of tests and experiments, the Huzzah32 client is quite stable and reliable to read the capacitive soil sensor.

After adding a ambient temperature and humidity sensor (AM2302 or DHT-22) and setting a dashboard using node-red, the project is ready for the final stage, using a PCB to hold the client.
