Ok now, all my devices are detected after isolating the code from the vertical and horizontal fins.
But I have an error on ligne 406 now.

(Climatisation) 'onHeartbeat' failed 'KeyError'.
(Climatisation) ----> Line 406 in /home/pi/domoticz/plugins/Melcloud/plugin.py, function onHeartbeat

Thank you very much, it works much better ! :D

But Domoticz detects just one device.
I have PARENTS and ENFANTS and just PARENTS is detected.

And when I send a command with Domoticz, the other instructions have changed to default in the MELCloud application.
I don't know why.

Log ...

Hello,

I have a little problem with MELCloud plugin in my Raspberry.
0 device is find.
The debug says :

MELCloud Login success. Key ID: XXXXXXXXXXXXXXXXXXXXXXXXX
Find 0 devices in MELCloud
Calling message handler 'onHeartbeat'.

Normally I have one building and 2 devices.

Have you an idea ...
