[Device] Aqara TVOC air quality monitor (VOCKQJK11LM) #241
Comments
HomeKit does seem to define a VOC Density characteristic as part of the Air Quality Sensor service. I'm assuming they are using these characteristics (and service), but you might be able to verify that with an adjusted version of the HMCatalog app. |
I found this scale for VOC Density (ppb), see TVOC bar. So i think we can assume:
For example now I have in my room 109 ppb and it is shown on device screen as 5 star = excellent. Is this scale enough to expose this Air Quality and VOC Density to HomeKit? |
Ideally we'd also have to combine other measurements from the sensor (in this case the relative humidity). |
I started working on the implementation and decided to keep the sensors separate. |
FYI: Initially I added this to the Basic Sensor handler, but ran into several issues. To make it a bit more comprehensive, I decided to make a separate file that handles the Air Quality sensors. I've just finished that implementation (I hope), but I have yet to write the automated tests for it (which is where I got stuck previously 😅). I'll let you know once it is released or available for testing somewhere. |
* Support for Air Quality sensor (see #241) * Reduce duplicate code for grouping ExposesEntries by their endpoint.
Just released v1.5.0 which should add support for this sensor (and a few others). Let me know if it works for you! 😉 |
I've noticed following warnings in logs and started to dig into VOC support in z2m/homebridge/homekit
What I've found:
Here is a discussion of the same issue and commit with changes for similar homebridge plugin |

Missing features/functionality
Only one thing is missing in Homekit, the VOC.
Suggested services and characteristics
I'm not sure here, but when conected this device via aquara hub it is exposed to HomeKIt like TVOC Sensor in climate section:
