I was looking for some cheep Air quality sensor, similar to JQ-300, but that wouldn’t relay on the internet connection, when I came across Air Box WP6003 from vson.com.
As it uses Bluetooth I thought I could easily integrated it with ESPHome (like this).
But after capturing some package I’ve noticed that it uses BLE indication and reading directly from the characteristic returns only 0 values. So I think generic integration is probably out of the question.
The data was also very cryptic, but fortunately somebody already did the work of decoding it - https://github.com/zu2/wp6003
(and right as I tip this I see he also uploaded a ESP compatible code)
I don’t have nothing to show yet (I ned to solder the bower cable back first ), but wanted to share this here if anybody else would find this useful.
