A tidy bedroom monitor that tracks temperature, humidity, CO2 and noise, with the noise reading being the unusual one for sleep: you can see whether a 3am spike coincided with a restless night. It is a cloud product, so readings go through Netatmo's servers, and the UK page showed it as 'Out of stock' at £109.99 when checked. Netatmo offers an app with Asthmatic, Baby and Family profiles, but the HA integration only gives you raw sensor values.
What can Home Assistant control on the Netatmo Smart Indoor Air Quality Monitor?
| Control | Type | What it does |
|---|---|---|
| CO2 | Sensor | Netatmo's page lists CO2 among the measured values; confirm the HA entity after setup. |
| Noise | Sensor | Netatmo lists noise as a real-time measurement; useful for correlating night disturbances. |
| Temperature and humidity | Sensors | Standard indoor readings, polled from Netatmo's cloud. |
Core Netatmo integration; HA lists the Smart Indoor Air Quality Monitor under supported sensors, classes it Cloud Polling, and says it needs a Netatmo account and an online device, with no webhook requirement for this model. The HA page does not enumerate its entities, so the noise, CO2 and health-index sensors are expected from the device's capabilities but were not confirmed in HA's docs. Expect polling delay and an outage whenever Netatmo's cloud is down. Apple Home compatibility is also advertised.
