How to share values between LM in diferent buildings (secure way)

[Daniel]

If they are located on same network you can use KNX IP secure. If they are not then you can use MQTT but you need broker somewhere. You can even use our cloud. If you add all LMs to the same cloud network then objects added to cloud will exchange data. Objects added to mosaic are the one exported to cloud or you can tag objects with tag 'lmcloud'
