Lots of good advice here, but if you have a running python script, then I guess there are two ways:
MQTT
REST API
both would require adding some lines to your program and if you use MQTT you would need to install and configure the MQTT broker as well, so maybe in your case REST API is the easiest.
In this post I explained how to do it for a DHT, but for the BME280 the part of the REST API works similar.
You would need 3 lines like:
requests.put('http://192.168.xxx.yyy:8080/rest/items/<YOUR HUMIDITYITEM>/state',value)
requests.put('http://192.168.xxx.yyy:8080/rest/items/<YOUR TEMPERATUREITEM>/state',value) .
requests.put('http://192.168.xxx.yyy:8080/rest/items/<YOUR PRESSUREITEM>/state',value)
and you might need to install the ‘requests’ module in Python by
. .pip install requests
In your items file you then define an item like
Number YOURHUMIDITYITEM "Humidity [%d] <youricon> etc for temperature and pressure. Use
‘f’ rather than ‘d’ if you want decimals.
