detect when button has been pressed, temperature has been changed on the device itself.

When the "boost" button on the eQ-3 device is pressed or the temperature has been changed on the eQ-3 device itself, then this is reflected in the response to the next get status request.

It would be good if the node-red flows would also report this as a separate event (a kind of changed-on-device-event).

This would make following use cases relatively easy to implement:

1. When the boost button on the eQ-3 is pushed, that this will also switch on the central heating (pump) if not yet the case.
2. When the temperature has been changed via the rotary knob on the eQ-3 that this will increase/decrease the volume of another IoT device.
