Missing CO2 ZCL cluster in Zigbee library

[Toximik]

Hi, 

I have started project with NUCLEO-WB55RG, which i planned to use as Zigbee router for my Home Assistant. I have manage to get temperature  working, then I wanted to add CO2 value (measured by SDC30 sensor) as next step but i have found out that CO2 cluster is missing from ZCL headers files provided by ST. So my question is: Does ST provide more up-to-date ZCL Cluster library or it is it possible to implement ZCL cluster for CO2 myself? Or there is some other solution?

Thanks for any advice.

Hello @Toximik 

The Carbon Dioxide (CO2) (cluster identifier from section 4.13.1.3 in ZigBee Cluster Library Specification rev. 8 https://zigbeealliance.org/wp-content/uploads/2021/10/07-5123-08-Zigbee-Cluster-Library.pdf#page=367) cluster identifier that you are mentioning is part of the Concentration Measurement (a collection of 32 subcluster), which is not implemented in our solution as of today.

Thus, from my perspective, you will need to implement it by yourself, by following the AN5491.

Best Regards.
