The Netatmo Thermostat Integration is now live and the Amazon Skill is available to use.
NOTE - This is not a ST integration but Echo to Netatmo.
Make sure you name your Thermostat to something sensible in your Netatmo account. Mine had my surname but thats the name you will need to use when setting the temp from Alexa.
I have changed it to Thermostat so now saying ‘Alexa set thermotsat to 18 degrees’ works fine.
