Random Activation with MIP Door Chimes
It is very rare for any Door Chime to randomly activate.
Usually this is because water has penetrated the outdoor bell push, or the bell push has been physically broken due to too much pressure exerted onto the button.
Check that the bell push or other transmitters have not been damaged or contain moisture.
If they have, please replace.
Alternatively, try a factory reset and then relink all devices, see Guides shown in this Q&Q section.
