Domoticz

Hi,
Installed the latest beta version of Domoticz.
Installed netmo plugin. Works !! OK...... but second collection of data fails 30 seconds later.
So : netatmo plugin gets registered.. creates devices.. works once... then stops working.. almost immediately. Thus the second data collection and al collections after that fail.
