CoolMaster IP
What it is
The CoolMaster IP box on the CoolMaster tab.
What to enter
The IP address of the CoolMaster unit on the home's network, for example 192.168.1.100.
What it changes
In the app: Nothing the owner sees directly; the app's CoolMaster ACs work through the hub.
In the house: The hub connects to this address for every AC set to CoolMaster at the next Save & Deploy. With no address the hub gets no CoolMaster module, and those ACs show without a gateway on the Rooms step.
If it goes wrong
If the ACs do not respond, check the address and that the hub can reach it.
