 +  - **central server required device list** so central server know which devices must be presents in order to turn central weather to good. If some devices are missing, central weather state is set to off.
 +  - **list of failed devices** in central server, so user knows from monitor why central server is in bad weather state.
 +  - **mootd**, which allows to connect two or more central server, and signals to all central server off states. If at least one central server is in hard off, mootd signals bad weather on all connected central servers.
