Question: fromZigbee.js type 'devChange' vs. 'attReport'? about zigbee-herdsman-converters HOT 3 CLOSED

I could be wrong, but AFAIK attReport event is always generated when a device reports a message, devChange only when the values change.

I would recommend to base your converter on attReport

attReport events happen on attribute changes when device.report() has been issued. devChange happens as a response after you write an attribute, when you specifically read a particular attribute, or when the device decides to send it to the coordinator even though it hasn't been specifically requested.

To be as comprehensive as possible, there is also statusChange which doesn't seem to be documented on the zigbee-shepherd wiki but is the message type you get from a report after using the enroll procedure. To my knowledge, this only happens with ssIasZone cids, but, I could be wrong.

@Koenkk , @dlashua - thanks for your answers and also thanks for pointing me at the zigbee-shepherd wiki again. I had been looking for it before, but had only checked the local version, but not the one at zigbeer which does provide all the information I was looking for.
