Hi,
I read this about setting min max values which allows to bring up the value of an attribute only if it has changed. This is very interesting for a Cstring for example. Can someone please confirm that this is correct (min:0 max:0)?
To set change based attribute reporting, you should set the maximum reporting interval field to 0x0000, and the minimum reporting interval field != 0xffff, so if you set both to 0x0000, it should be set to change based reporting. This is from the Zigbee cluster library specification Revision 7.
I tested on a Cstring and it seems to work. I would like to be sure that it goes back to a change and not constantly.
{
“at”: “0x0010”,
“dt”: “0x42”,
“min”: 0,
“max”: 0
},
