Thanks for mentioning this. I had looked at these before, but was holing off due to the cloud-polling home assistant integration.

ESPHome has an integration for the Airthings Wave Plus: https://esphome.io/components/sensor/airthings_ble.html This is working well for me on a NodeMcu ESP32 with WiFi and Bluetooth. No soldering required. This makes it possible to integrate with Home Assistant without sending your data to Airthings HQ.
