Cluster 0x80 → Displays (Multicast) 0xe7
Unlike the radio or telephone which sends display data at the time it’s required, the cluster will send display data at regular intervals irrespective of what is being displayed.
Essentially, radio and telephone displays are “lazily loaded”, and the cluster displays are “eager loaded”.

Seemingly always 0x00.
String
- ASCII encoding.
- The length is determined by the property.
- The unit/format of the property will be as per
0x15, i.e. 24H vs. 12H etc. - GT will parse some strings (presumably to generate a native object), thus the string format is restricted.
