@AlecM, You should try to move those bulbs somewhere to the edge of your network, where they wouldn’t be used as repeaters.
Or, you can change them to cheaper and more reliable IKEA bulbs. (Osram sockets are working well as repeaters.)
I have got a proof how bad repeaters they are:
@Adam_Young, that is the reason why the sensor has written on it next to the battery place what battery to use. Otherwise, the side terminal can be bent to a level to work with the battery on the right as well.
