Netatmo Smart Thermostat on OH3

I’ve made first installation of OH3 (I never used OH in the past )
I’d like to learning it and I’d like to install Netatmo Smart Thermostat and some component od Xiaomi Hub ( sensors, robot cleaner, etc etc )
However for Netatmo, I saw online to take client secret and client ID, so I take it, but I’ve problem to configure binding and … all :frowning:

Thanks in advance
