Below is my configuration for the ESP8266 with SDS011 and BME280 sensors. The main reason the run it with ESPHome instead of the stock firmware is direct integration into Home Assistant and native MQTT support. I still push my data to opensensemap.org but it’s now handled by Home Assistant instead. I used the following instructions to set up the opensensemap integration: https://hmmbob.tweakblogs.net/blog/18950/push-data-to-luftdaten-and-opensensemap-with-home-assistant
