Hello guys. I am finding some certified sensors as in the title.
They should be compliant to EN 50194 for Gases, and 50291-1:2018 for carbon monoxyde.
Since they’re mandatory in a Bed & Breakfast (where i have kiosk tablets in each room), would be great to inform the customer of the air quality (drawing a graph also).
I’ve found two ioT devices (one for each certification), but i don’t know if they can be integrated in HA.
Delivered. They are tuya compatible, so i’ve easily integrated it into homeassistant.
They give infos about Battery and alarm (on/off).
However a CO (or CO2) graph would been nicer.
Maybe i’ll add it with an ESP32 + CO2 sensor paired with some led stuff to control.
