Last night, I upgraded my weather setup here at home. Outside, I have an Acurite 5 in 1 sensor, which measures rain, temperature, humidity, and wind. There is a newer version that adds UV. light intensity, and optionally lightning. One of the things missing is a barometer. So, I acquired a BME280, which is a temperature, humidity, and pressure sensor.  I don’t do much Python, but it was the library I could find, so I hooked it into a Pi I already had running sensor collection, hacked together a script with the Adafruit library for the sensor to collect the data and publish it to an MQTT broker, then imported it into Weewx, where my data from the other sensor is stored. Fun. Trying to figure out what’s next. I don’t think I can do an outdoor sensor as easily.
