Sorry, probably not much help from me here. I've been using DIY stations thrown together from ESP32 development boards and low-cost Plantower sensors (PMS5003 and PMS7003). They're surprisingly accurate — my measurements over the past three years closely match the official government data (which is collected using calibrated "professional" air quality stations priced at $10k or more). It's cheap, but you have to do everything yourself. A friend of mine did something similar, but using ESPHome and Home Assistant, and I think he didn't have to write any code at all, just a bit of YAML to tie it all together. https://github.com/esphome/esphome https://home-assistant.io/ |
