1. IoT (and other) devices randomly go offline and some seconds/minutes later go back online. This is annoying as they are controlled by timed routines/scenes and if a device is offline when it should be turning off (like the hot water immersion heater), it remains on, costing money.

2. To try to understand this I used connection alerts for known devices. However, this only works randomly. I have to do each device separately and it often fails to set up, saying "try again later".
