Thank you @tsavikos @overeasy I think I have made progress in my problem; but unfortunately it isn’t resolved yet.
I configured my server to accept http, and entered 1 in the used id box, but my emoncms server still does not receive anything. I can see however that my server seems to not have a problem because when I try a command like this one : http://outils-numeriques.ines-solaire.org/mesuresPEB/input/post.json?node=999&json={test:30.1}&apikey=MYAPIKEY , it receive it. Do you have an idea of what could resovle the problem?
