MCOHome MH9-CO2 new firmware

[IanDury]

I recently bought this device and apparently it has a firmware upgrade that changed the parameter settings as well as the association groups. After successful inclusion with Domoticz it did not report the sensor values.

Using the specification sheet that can also be downloaded from http://www.mcohome.com/ProductDetail/3897790.html I modified the OZW configuration file mh9co2.xml and now it works fine for me.

Modified mh9co2.xml:
