Broadcast messages
The primary bit to look at when deciding what type of message is being broadcast is the Action/Command bit.
For this, we know:
Actions
1: 'Ack Message',
2: 'Controller Status',
5: 'Date/Time',
7: 'Pump Status',
8: 'Heat/Temperature Status',
10: 'Custom Names',

224: 'Get is4/is10 Settings',
225: 'Get Intelliflo Spa Side Remote settings',
226: 'Get Solar/Heat Pump',

232: 'Get Settings, Heat Mode?',
252: 'SW Version Info',
253: 'Get SW Version'
There is a relationship between the various Status, Get, and Set messages. The low order bits designate the type of message and the high order bits control whether or not you are requesting the current status or setting the current values. For example the Date/Time message is type 5(00000101). To request the Date/Time you would set the top two bits resulting in a type of 197(11000101). To set the Date/Time you would set only the topmost bit resulting in a type of 133(10000101). The same seems to apply to many of the other message types.
Get Requests
All get requests are of the same form. The action is set as defined above. The payload is a single byte. For simple requests that byte is 0, when requesting something that has more than one return value that byte is the index.
